Number of Jordan blocks of the maximal size for local monodromies

description: We prove formulas for the number of Jordan blocks of the maximal size for local monodromies of one-parameter degenerations of complex algebraic varieties where the bound of the size comes from the monodromy theorem. In case the general fibers are smooth and compact, the proof calculates some part of the weight spectral sequence of the limit mixed Hodge structure of Steenbrink. In the singular case, we can prove a similar formula for the monodromy on the cohomology with compact supports, but not on the usual cohomology. We also show that the number can really depend on the position of singular points in the embedded resolution even in the isolated singularity case, and hence there are no simple combinatorial formulas using the embedded resolution in general.

Interacting effects of multiple herbivore guilds on the fitness and demography of a savanna tree.
Creators: name: Maclean, Janet Elizabeth
Publisher: name: University of British Columbia
Year: 2012

description: Plant populations are limited by a diverse array of herbivores that restrict growth and survival throughout the plant’s life cycle. Few studies, however, simultaneously quantify the impacts of multiple herbivore guilds on the lifetime performance or population growth rate of plants. In African savannas, large ungulates such as elephants are important drivers of woody plant population dynamics, while the potential impacts of smaller, more cryptic herbivores such as rodents, have largely been ignored. I integrated a five-year manipulation of rodent densities into a large-scale ungulate exclusion experiment to quantify the impacts of three herbivore guilds - wild ungulates, domestic cattle, and rodents - on all life stages of a widespread savanna tree, Acacia drepanolobium. I used demographic modeling to determine the overall influence of each guild on tree population dynamics, and to determine the importance of different demographic stages in limiting population growth under contrasting consumer communities. I showed that wild ungulates dramatically reduced population growth (λs reduced from 1.06 to 0.98), shifting the population trajectory from increase to decline. The processes that drive these effects, however, were strongly mediated by rodents. The impact of wild ungulates on population growth was predominantly driven by their negative effect on tree reproduction when rodents were excluded, and on adult tree survival when rodents were present. By limiting seedling survival, rodents also reduced population growth (decrease in λs from 1.06 to 1.01); however, this effect was strongly dampened where wild ungulates were present (decrease in λs from 0.98 to 0.97). I suggest that these complex interactions between disparate consumer guilds can have important consequences for the population demography of long-lived species, and that the effects of a single consumer group are often likely to vary dramatically depending on the larger community in which interactions are embedded.

description: As a founder and director of Pugliese Enterprises, a family-run film exhibition and production company, Caroline Pugliese owned and operated three theatres in Sydney from 1909 until 1922—the Alhambrain Haymarket, the Star Theatre in Bondi, and the Broadway in Leichhardt. According to reports in Kino Cinema International, running the theatres was a hands-on activity for the entire Pugliese family, with Caroline controlling the company finances and helming major business decisions and her children acting as ticket-sellers and projectionists (18). The Puglieses subsisted at the lower, populist end of the market, eking out an existence by showmanship and adding value via music and performance to film screenings. Like other small exhibitors in these early days, Pugliese experienced difficulty accessing a ready supply of motion pictures for screening, which may have prompted her foray into film production in partnership with son Humbert in 1917.

description: We solve the Anderson localization problem on a two-leg ladder by the Fokker-Planck equation approach. The solution is exact in the weak disorder limit at a fixed inter-chain coupling. The study is motivated by progress in investigating the hybrid particles such as cavity polaritons. This application corresponds to parametrically different intra-chain hopping integrals (a "fast" chain coupled to a "slow" chain). We show that the canonical Dorokhov-Mello-Pereyra-Kumar (DMPK) equation is insufficient for this problem. Indeed, the angular variables describing the eigenvectors of the transmission matrix enter into an extended DMPK equation in a non-trivial way, being entangled with the two transmission eigenvalues. This extended DMPK equation is solved analytically and the two Lyapunov exponents are obtained as functions of the parameters of the disordered ladder. The main result of the paper is that near the resonance energy, where the dispersion curves of the two decoupled and disorder-free chains intersect, the localization properties of the ladder are dominated by those of the slow chain. Away from the resonance they are dominated by the fast chain: a local excitation on the slow chain may travel a distance of the order of the localization length of the fast chain.

Korea's financial evolution: A personal perspective

description: When the Asian financial crisis first reared its ugly head in South East Asia, nobody knew how long, how awful, and how catastrophic Asian money centers would be rocked. And rocked they were, especially in Korea, as well as several other economies. Running a trade deficit for several years leading up to 1997, when several firms began to go bankrupt, Korean financial markets panicked, and fear took over. In late 1997, foreign banks,which had extended short-term credit to many Korean financial institutions, left a dust trail as they all bailed out, leaving banks and the Korean central bank clamoring for liquidity. The stock market and the won were devalued by about 50 percent as fear swept through the nation. Newspapers across the globe showed women hawking their jewelry and crying, while nationalism set in and everyone bought Korean instead of foreign goods. The International Monetary Fund and other global financial institutions all joined hands to help, and to this day, economists and other officials argue about how effective the IMF was or was not in the region.It was a dramatic moment in Korean financial history, but the results were spectacular. The government set high standards in the financial sector and forced banks to merge and restructure. New laws were set in place. And for the first time, the ownership of financial institutes was opened to foreign direct investment. Enter Robert Fallon, Chairman of Korea Exchange Bank, a $60 billion institution and the leading international bank in South Korea. In spring 2004 Mr. Fallon became the first foreigner to chair a publicly traded corporation in the history of South Korea after the U.S. investment group Lone Star took over the bank in 2003. He has charismatically led the bank's turnaround through vigorous restructuring, with bank profits reaching $509 million in 2004, after a $209 million loss in 2003. On February 28, 2005, the APEC Study Center (ASC) and the Program on Alternative Investments of the Center on Japanese Economy and Business (CJEB) at Columbia University hosted a symposium featuring Mr. Fallon about the evolution of Korea's financial sector. Lee Branstetter, Daniel W. Stanton Associate Professor of Business, presided,and Mark Mason, Director of the Program for Alternative Investments and Associate Director for Programs of CJEB, was the moderator.
Development of the Sage-King narratives : idealized concepts of rulership in Warring States Chinese thought
Creators: name: Chen, Chung Kuang Allen
Publisher: name: University of British Columbia
Year: 2012

description: The purpose of this thesis is to investigate how contemporary scholarship interpreted sage-kings (聖王) narratives, commonly used in Warring States and Chinese philosophical texts to represent particular visions of ideal rulership, in their understanding of the historical and political contexts of the development of early Chinese intellectual history. Another aim is to find out how these narratives changed over time, and how they revealed the different political concerns of the Warring States philosophers. This project uses a primarily historiographical approach and first surveyed the works of leading scholarship in the field that discusses the use of the sage-kings. Then, two particular narratives are examined in order to demonstrate their evolution over time. The first of these sage-king narratives was on the taming of the great flood by Yu 禹 and the rise of human civilization; the second was on the abdication of Yao 堯 to Shun 舜 and the issue of legitimacy in the transfer of political authority. The results of the study shows that even though contemporary scholarship recognizes the importance of the sage-king narratives in understanding political concerns in the history of early China, and the evolution of these narratives over time, there is no consensus in the methodology best used to systematically integrate them. This thesis also concludes that that the sage-kings were used not just as political ideals by texts like the Analects, the Mozi, the Mencius, and the Xunzi, but were also often consciously constructed by the authors of these texts to fulfill this precise role. Furthermore, the results indicate that the sage-kings were also used as counter-narratives by the Zhuangzi and the Hanfeizi, as a way to criticize and undermine those texts that were proponents of the sage-kings. The principal conclusion of this thesis is that sage-kings narratives are more complex and multifaceted than previously thought and deserve a more nuanced and historically aware analysis in future research.

description: Like many other early Russian film actors, Ol’ga Rakhmanova entered into a new career after a long professional life in theater, mostly in the provinces. She was born in Odessa, Ukraine, then part of the Russian Empire, sometime in 1871 and studied there at the Drama School of the Russian Music Society. Abandoning her married name, Sokolova, and her three children, she first acted in semi-amateur troupes. In 1896, as the first Lumière films were shown in Moscow and Saint Petersburg, she made her professional stage debut under the guidance of a well-known provincial entrepreneur, Konstantin Nezlobin, in Vilna, now Vilnius, Lithuania. However, it would take her almost twenty years to branch out into cinema.

description: Disordered and frustrated graphical systems are ubiquitous in physics, biology, and information science. For models on complete graphs or random graphs, deep understanding has been achieved through the mean-field replica and cavity methods. But finite-dimensional `real' systems persist to be very challenging because of the abundance of short loops and strong local correlations. A statistical mechanics theory is constructed in this paper for finite-dimensional models based on the mathematical framework of partition function expansion and the concept of region-graphs. Rigorous expressions for the free energy and grand free energy are derived. Message-passing equations on the region-graph, such as belief-propagation and survey-propagation, are also derived rigorously.

It has been wrongly identified as M. tribulus Linné, 1758 in many publications but differs from M. tribulus in having a more nodose (cancellate) sculpture, fewer spines on the siphonal canal, and more rounded and nodose first teleoconch whorls (Ponder & Vokes 1988: 24). Both species have a conical multispiral protoconch, indicating planktotrophic larval development.

description: As a girl in England at the turn of the century, Olga Petrova (born Muriel Harding) felt stifled by her father’s strict rules. According to her memoir, Petrova’s father told her that while she lived in his house and ate his bread, he would set the rules. Petrova was determined to live in her own house and eat her own bread (Petrova 55-56). Her success in reaching this goal, and more, is reflected in the title of her memoir, Butter with My Bread.

Inter-Host Reassortment Patterns in Swine Influenza Viruses

description: Three pandemic influenza strains occurred in the 20th century, in 1918, 1957 and 1968. Influenza pandemic strains are the result of an emerging virus spreading in people which have little or non immunity. At least two of these pandemics strains, in 1957 and in 1968, were the result of reassortments between human and avian viruses. In 1957 three segments, PB1, HA and NA, and in 1968 two segments, PB1 and HA, were of avian origin. Recently new influenza viruses have been isolated in Mexico and the United States. These viruses are found to be a complicated reassortement of swine, avian and human strains. Pigs are frequently found co-infected with human, avian and swine viruses. This observation has led to the conjecture that pigs are the mixing vessel that cause the avian-human reassortments, and hence the pandemics. Understanding the process and the patterns of viral reassortment, especially in pigs, is key to estimate and/or predict the likelihoods and rates of influenza pandemics. In the last few years databases collecting the sequences of influenza viruses in diverse geographical locations since 1918, including swine viruses, have been developed and made publicly available. In this paper, we study the ensemble of the swine influenza viruses to analyze how the reassortments happen in pigs. Inter-host reassortment patterns in pigs confirm similar previous results found in human viruses, both in vitro and in vivo. More interestingly, we have found that one of the polymerases, PB1 reassorts more often than other segments. In the last two pandemics, 1957 and 1968, PB1 was of avian origin. This observation reinforces the hypothesis that pigs constitute the inter-host mixing vessel responsible for at least two of the three pandemics in the 20th century.

description: Screenwriter, short film director, and best-selling novelist, Elizabeth Pickett began her career in motion pictures directing a series of documentary films for the American Red Cross near the end of World War I. Much later, in 1942, she published an extremely successful novel (fittingly entitled Drivin’ Woman) as Elizabeth Chevalier, her maiden name. In interviews given around that time, she frequently mentions her early experiences working in film as crucial to her work as a novelist (although the novel does not deal with women in the film industry). But by the time she published the novel, much of her earlier work in the silent film industry had already been forgotten.

description: Rosa Porten’s work as a screenwriter, an actress, and a film director has been practically neglected in film history, but what she accomplished in the German silent cinema is truly noteworthy. In a two-decade career, from 1906 until 1928, she created a cinematic oeuvre that was substantial, original, versatile, and entertaining. The exact number of films to which Rosa Porten contributed is uncertain, but historical substantiation points to around forty titles. Between 1916 and 1919 alone, she wrote and co-directed at least twenty-four catching comedies and gripping social dramas and in most of them she played the protagonist. Even more notable in retrospect is that Porten’s stories often privileged the perspective of a female character who, with non-conformist pragmatism or jokey recalcitrance, seizes her chance to defy bourgeois conventions and role patterns. In the trade press, the comedies were often praised: 1e Internationale Film-Zeitung highlighted the “überschäumende Komik” [scintillating jocoseness] of Die Film-Kathi (1918) (1918, 47); Der Kinematograph noted the “herzerfrischenden” [heart-freshening] humor in Die Erzkokette (1917) (1917, n.p.); both Der Film and 1e Internationale Film-Zeitung noticed the serious undertones in Der Neueste Stern vom Varieté (1917) and Das Musikantenmädel (1918) respectively (1917, 57; 1918, 58).

Also from off Port Hedland, Western Australia. REMARKS. — At first sight, the Fiji specimens seem to differ from typical M. troscheli (in their heavier varices, narrower axial ribs, and absence of brown colouration at the top of the spiral cords); however, a careful study of the protoconch, spiral and axial sculpture of the teleoconch whorls, and organization of the spines leaves no doubt about their correct identification. The shells from Fiji are uniformly whitish, smaller and more slender than the typical form. They could be considered as intermediate between the typical form, from the Philippines, and the form named M. heros Fulton, 1936 from the Solomon Islands.

description: As Brazil is one of the economically uprising and promising BRIC countries, its development involves chances and risks. If unjust conditions remain, its long-term advancement is rather unlikely. The changes within the country are especially visible and present in its principal metropolis: São Paulo. In order to analyze its present situation in terms of spatially produced social (in)justices, some questions must be answered: How is spatial justice produced and by which processes? How are those processes integrated in Brazil’s urbanization development? Which effects does it have on the urban structure of São Paulo? And finally: Which socio-spatial development tendencies do the actual public policies and their realization within the metropolis suggest? This bachelor thesis outlines a theoretical base of the term spatial justice, the development of Brazil - and in this context the effects on São Paulo’s urbanization - with respect to its economy, politics, society, history, and especially urbanization in order to analyze São Paulo’s socio-spatial development and present situation in a multidimensional context. Applying Henri Lefèbvre’s, David Harvey’s, and Edward Soja’s theories on spatial justice on the public policies of the metropolis since the City Statute of 2001 – a major change in Brazil’s urban politics –, the author looks into their conformance with the necessary production conditions of spaces of justice.

description: Models of new physics induce K-Kbar mixing operators having Dirac structures other than the "left-left" form of the Standard Model. We calculate the functional form of the corresponding B-parameters at next-to-leading order in both SU(3) and SU(2) staggered chiral perturbation theory (SChPT). Numerical results for these matrix elements are being generated using improved staggered fermions; our results can be used to extrapolate these matrix elements to the physical light and strange quark masses. The SU(3) SChPT results turn out to be much simpler than that for the Standard Model B_K operator, due to the absence of chiral suppression in the new operators. The SU(2) SChPT result is of similar simplicity to that for B_K. In fact, in the latter case, the chiral logarithms for two of the new B-parameters are identical to those for B_K, while those for the other two new B-parameters are of opposite sign. In addition to providing results for the 2+1 flavor theory in SU(3) SChPT and the 1+1+1 flavor theory in SU(2) SChPT, we present the corresponding continuum partially quenched results, as these are not available in the literature.

description: This paper traces the profound decline in German unionism over the course of the last three decades. Today just one in five workers is a union member, and it is now moot whether this degree of penetration is consistent with a corporatist model built on encompassing unions. The decline in union membership and density is attributable to external forces that have confronted unions in many countries (such as globalization and compositional changes in the workforce) and to some specifically German considerations (such as the transition process in postcommunist Eastern Germany) and sustained intervals of classic insider behavior on the part of German unions. The ‘correctives’ have included mergers between unions, decentralization, and wages that are more responsive to unemployment. At issue is the success of these innovations. For instance, the trend toward decentralization in collective bargaining hinges in part on the health of that other pillar of the dual system of industrial relations, the works council. But works council coverage has also declined, leading some observers to equate decentralization with deregulation. While this conclusion is likely too radical, German unions are at the cross roads. It is argued here that if they fail to define what they stand for, are unable to increase their presence at the workplace, and continue to lack convincing strategies to deal with contemporary economic and political trends working against them, then their decline may become a rout.

description: Olga Printzlau was a prolific writer who began her career as an artist, but turned to screenwriting after becoming interested in the “literary possibilities” of film. By 1920 she was credited with having written 352 produced scenarios (“Olga Printzlau to Write” 183). During the twenties she was sought after for her skill in adapting popular stories and novels to the screen, most notably F. Scott Fitzgerald’s The Beautiful and the Damned (1922) and Edith Wharton’s The Age of Innocence (1924). But by the late 1920s Printzlau’s attention seems to have turned more to her theatre work, and her film career dwindles significantly after 1930, with no known screen credits after 1933.

description: We present the results of the magnetization and dielectric constant measurements on untwinned single crystal samples of the frustrated S=1/2 chain cuprate LiCu_2O_2. Novel magnetic phase transitions were observed. A spin flop transition of the spiral spin plane was observed for the field orientations H||a,b. The second magnetic transition was observed at H~15 T for all three principal field directions. This high field magnetic phase is discussed as a collinear spin-modulated phase which is expected for an S=1/2 nearest-neighbor ferromagnetic and next-nearest-neighbor antiferromagnetic chain system.

description: Temporal event correlation is essential to realizing self-managing distributed systems. Autonomic controllers often require that events be correlated across multiple components using rule patterns with timer-based transitions, e.g., to detect denial of service attacks and to warn of staging problems with business critical applications. This short paper discusses automatic adjustment of timer values for event correlation rules, in particular compensating for the variability of event propagation delays due to factors such as contention for network and server resources. We describe a corresponding Management Station architecture and present experimental studies on a testbed system that suggest that this approach can produce results at least as good as an optimal fixed setting of timer values.
An Analytic Model for the Evolution of the Stellar, Gas, and Metal Content of Galaxies

description: We present an analytic formalism that describes the evolution of the stellar, gas, and metal content of galaxies. It is based on the idea, inspired by hydrodynamic simulations, that galaxies live in a slowly-evolving equilibrium between inflow, outflow, and star formation. We argue that this formalism broadly captures the behavior of galaxy properties evolving in simulations. The resulting equilibrium equations for the star formation rate, gas fraction, and metallicity depend on three key free parameters that represent ejective feedback, preventive feedback, and re-accretion of ejected material. We schematically describe how these parameters are constrained by models and observations. Galaxies perturbed off the equilibrium relations owing to inflow stochasticity tend to be driven back towards equilibrium, such that deviations in star formation rate at a given mass are correlated with gas fraction and anti-correlated with metallicity. After an early gas accumulation epoch, quiescently star-forming galaxies are expected to be in equilibrium over most of cosmic time. The equilibrium model provides a simple intuitive framework for understanding the cosmic evolution of galaxy properties, and centrally features the cycle of baryons between galaxies and surrounding gas as the driver of galaxy growth.

description: In loop quantum gravity, states of the gravitational field turn out to be excitations over a vacuum state that is sharply peaked on a degenerate spatial geometry. While this vacuum is singled out as fundamental due to its invariance properties, it is also important to consider states that describe non-degenerate geometries. Such states have features of Bose condensate ground states. We discuss their construction for the Lie algebra as well as the Weyl algebra setting, and point out possible applications in effective field theory, Loop Quantum Cosmology, as well as further generalizations.

description: Mary Pickford was born Gladys Smith in 1892 in Toronto, Canada. After her father was killed in an accident, Gladys became the family’s main breadwinner by performing in the theatre. She was seven years old. In fact, the stage became a family venture, as her younger siblings Lottie and Jack and even her mother took up the trade. But the drive and determination to be a star belonged solely to Gladys. In 1907, her ambition would take her to Broadway and famed producer-director David Belasco, who changed her name to Mary Pickford and gave her a part in “The Warrens of Virginia.”

description: Although best known as the premiere Hollywood gossip columnist of the classical Hollywood studio era, Louella Parsons began her career in the film industry in 1911 when she was hired by the Chicago-based production company Essanay as its chief scenario editor. Referencing a story published in Louella’s hometown Illinois newspaper the Dixon Telegraph in 1936, Parsons biographer Samantha Barbas writes that, although Parsons’s application for the position was initially discarded, she ingratiated herself with Essanay cofounder George Spoor’s wife, who subsequently persuaded Spoor to hire her. Barbas’s account of Louella’s hire differs slightly from that of Louella herself, put forward in her best-selling 1944 book, The Gay Illiterate. Barbas writes that Louella, upon discovering that her cousin Margaret Oettinger was friendly with Ruth Helms, the daughter of George Spoor’s wife’s closest acquaintance, begged the little girl to introduce her to Mrs. Spoor in exchange for movie tickets. In contrast, Parsons recalls that Helms was so impressed by a scenario she had written entitled Chains that the twelve-year-old took it upon herself to acquire Louella a job in the film industry: “Ruth hounded poor Mrs. Spoor so unmercifully that she, in turn, hounded her busy husband into giving me the appointment.” Parsons notes that Essanay not only hired her as scenario editor, but purchased the scenario for the sum of twenty-five dollars. Although no longer extant, Parsons reports that Chains was produced in 1912 staring Essanay heartthrob Francis X. Bushman (Barbas 2005, 33; Parsons 1944, 20–21).
Leipzig Glossing Rules

description: The Leipzig Glossing Rules have been developed jointly by the Department of Linguistics of the Max Planck Institute for Evolutionary Anthropology (Bernard Comrie, Martin Haspelmath) and by the Department of Linguistics of the University of Leipzig (Balthasar Bickel). They consist of ten rules for the "syntax" and "semantics" of interlinear glosses, and an appendix with a proposed "lexicon" of abbreviated category labels. The rules cover a large part of linguists' needs in glossing texts, but most authors will feel the need to add (or modify) certain conventions (especially category labels). Still, it will be useful to have a standard set of conventions that linguists can refer to, and the Leipzig Rules are proposed as such to the community of linguists. The Rules are intended to reflect common usage, and only very few (mostly optional) innovations are proposed.

description: Many plant-level studies find that average wages in exporting firms are higher than in non-exporting firms from the same industry and region. This paper uses a large set of linked employer-employee data from Germany to analyze this exporter wage premium. We show that the wage differential becomes smaller but does not completely vanish when observable and unobservable characteristics of the employees and of the work place are controlled for. For example, blue-collar (white-collar) employees working in a plant with an export-sales ratio of 60 percent earn about 1.8 (0.9) percent more than similar employees in otherwise identical non-exporting plants.
A Well-Posed Kelvin-Helmholtz Instability Test and Comparison

description: Recently, there has been a significant level of discussion of the correct treatment of Kelvin-Helmholtz instability in the astrophysical community. This discussion relies largely on how the KHI test is posed and analyzed. We pose a stringent test of the initial growth of the instability. The goal is to provide a rigorous methodology for verifying a code on two dimensional Kelvin-Helmholtz instability. We ran the problem in the Pencil Code, Athena, Enzo, NDSPHMHD, and Phurbas. A strict comparison, judgment, or ranking, between codes is beyond the scope of this work, though this work provides the mathematical framework needed for such a study. Nonetheless, how the test is posed circumvents the issues raised by tests starting from a sharp contact discontinuity yet it still shows the poor performance of Smoothed Particle Hydrodynamics. We then comment on the connection between this behavior to the underlying lack of zeroth-order consistency in Smoothed Particle Hydrodynamics interpolation. We comment on the tendency of some methods, particularly those with very low numerical diffusion, to produce secondary Kelvin-Helmholtz billows on similar tests. Though the lack of a fixed, physical diffusive scale in the Euler equations lies at the root of the issue, we suggest that in some methods an extra diffusion operator should be used to damp the growth of instabilities arising from grid noise. This statement applies particularly to moving-mesh tessellation codes, but also to fixed-grid Godunov schemes.

description: Mrs. M. T. Pender was a prolific Ulster fiction writer and outspoken nationalist whose serialized novel, O’Neill of the Glen (1891), was the source for the Film Company of Ireland’s (FCOI) first indigenous Irish feature, O’Neil of the Glen (1916). The FCOI was incorporated in March 1916 with the goal of producing Irish films with Irish themes and an all-Irish cast and crew, according to “Irish Film Production” (1916, 6). The Irish Limelight reports in “What the Irish Film Co. is Doing,” however, that never-released work was destroyed in the Dame Street office fires during the Easter Rising in April: “… the first three months work was wiped out in a week” (1917, 3). The FCOI immediately resumed production and O’Neil of the Glen was released to censors and the press in June, exhibitors in July, and the public in August. It is widely regarded, then, as the company’s first production. Founded and managed by Jim Sullivan and Ellen O’Mara Sullivan, the FCOI went on to produce highly nationalist films until 1920 when O’Mara Sullivan died. Pender’s writing, which promoted Irish culture and advocated a free and united Ireland, appealed to the company’s nationalist leanings.
Role of E-cadherin in the serous borderline ovarian tumor and low-grade serous ovarian carcinoma cell invasion
Creators: name: Cheng, Jung-Chien
Publisher: name: University of British Columbia

description: E-cadherin is a membrane glycoprotein located at cell adherens junctions. A switch from E-cadherin to N-cadherin expression has been considered a hallmark of the epithelial-mesenchymal transition (EMT), which is primarily due to the up-regulation of the transcription factors Snail, Slug, Twist and ZEB1. Epithelial ovarian cancer cells with low E-cadherin expression are more invasive, and the absence of E-cadherin expression in ovarian cancer is associated with poor prognosis and survival. Serous borderline ovarian tumors (SBOT) are slow-growing, non-invasive ovarian epithelial neoplasms. SBOT are considered distinct entities that give rise to invasive low-grade serous carcinomas (LGSC), which have a relatively poor prognosis and are unrelated to high-grade serous carcinomas (HGSC). The mechanisms underlying the progression of non-invasive SBOT to invasive LGSC are not understood. We have established short-term cultures of SBOT cells from tumor biopsies and have shown that inactivation of p53, Rb and/or PP2A by the SV40 large T (LT) and small T (ST) antigens allows SBOT cells to acquire characteristics associated with neoplastic progression, including increased cell motility, invasion and EMT. However, the overexpression of N-cadherin does not induce cell invasion in SBOT cells. In this study, using loss- and gain-of-function approaches, we show that p53 acts as a tumor suppressor in the regulation of SBOT and LGSC cell invasion by regulating E-cadherin expression through PI3K/Akt-mediated transcriptional and epigenetic machineries. In high-grade ovarian cancer cultures, it has been shown that epidermal growth factor (EGF) and transforming growth factor-beta (TGF-β) induce cell invasion by activating the EMT. However, the effects of EGF and TGF-β on SBOT and LGSC cell invasion remain unknown. We show that EGF induces SBOT cell invasion by activating the EMT. In addition, our results suggest that there are EMT-independent mechanisms that mediate EGF-induced LGSC cell invasion. Interestingly, we show a dual function for TGF-β in which it induces invasion in SBOT cells by activating the EMT and promotes apoptosis in LGSC cells. Overall, this study demonstrates that the loss of E-cadherin expression in SBOT may play an important role in the transition to invasive LGSC.
