Regulation of Chromatin by FACT and NuA3
Creators: name: Chruscicki, Adam Tadeusz
Publisher: name: University of British Columbia
Year: 2014

description: The presence of nucleosomes over vast regions of genome negatively influences transcription creating a need for temporal and structural regul ation of chromatin. The default transcription-repressive state can be countered by addition of post-translational modifications by ch romatin modifiers or chromatin alteration by histone chaperones. Chaperones alter chromatin structure before the RNAPII passage and restore it afterwards. How modifiers and chaperones function within chromatin is an area of intense research. Here we show how two complexes, the yeast FACT and NuA3 contribute to chromatin function. Yeast Facilitates Chromatin Transactions (yFACT) is a histone chaperone that maintains chromatin structure. The model of yFACT function in vivo is a subject of much debate. We provide evidence that yFACT acts by stably binding and altering nucleosomes. We also present the EM structure of yFACT associated with nucleosomes. We find that yFACT-associated nucleosomes are hyper-acetylated and show evidence for it being an effect of a direct interaction between yFACT and NuA3. At the same time, acetylation of the H3K56 residue by the histone acetyltransferase Rtt109, acts to recruit yFACT to chromatin through a nucleosome-dependent mechanism. To determine the distribution of yFACT- associated nucleosomes we constructed a map of yFACT-nucleosome localization at single-nucleosome resolution. We show that while yFACT-bound nucleosomes are distributed thought the genome they are also positioned over the canonical Nucleosome Depleted Regions (NDR). The yFACT- bound nucleosomes are positioned around TATA-elements and Nhp6 - target sequences genome-wide. Deletion of NHP6A/B leads to loss of chromatin at these loci. Our work suggests the first ever sequence-dependent mechanism of histone chaperone action in Saccharomyces cerevisiae. We also examined NuA3 recruitment to chromatin and showed that Yng1, a subunit of NuA3 with a known affinity for H3K4me3 is a bivalent protein. While as previously shown, the C-terminal PHD finer of Yng1 binds to H3K4me3, the N-terminus of Yng1 can also bind to unmodified chromatin. Although these motifs can bind independently, together they increase the apparent association of Yng1 with chromatin. Yng1 binding to chromatin is regulated by the HDA1 complex.

description: In genetic and genomics, Linkage disequilibrium (LD) is a fundamental concept playing critical roles in association mapping and molecular evolution. However, LD is only appropriate for assessing the association between common genetic variants, leaving rare variants that account for 90% of human variants unattended. This is because the low allele frequency of variants lead to very high uncertainty. Therefore the LDs are not stable at all. To bridge this gap, we proposed a novel statistic, cumulative Linkage Disequilibrium (cLD) based on rare variants to capture the associations between genes.To verify that the new statistic could reveal the interactions between genes, we calculated cLD basing on the 1000 Genomes Project dataset and designed a rigorous statistical test to analyze cLD’s properties. Notably, by calculating LD between common variants using the same data, other scholars reported negative results stating that the genetic LD map is not overlapping with 3D contact map (assessed by the Hi-C experiments)[20]. However, by reanalyzing the same data using cLD, we revealed positive results that the 3D chromatin interactions did leave genetic footprints. Moreover, the cLD of interacting gene pairs (as reported by the various database of interactions) is significantly higher than the cLD of non-interacting gene pairs. To quantify why cLD is stable despite the allele frequency being extremely low, we further investigated the theoretical properties of cLD by deriving the closed-form variance of cLD and LD. We proved that var(cLD) has lower magnitudes than var(LD) when the genetic variants are rare.

description: The s-wave pion-kaon ($πK$) scattering lengths at zero momentum are calculated in lattice QCD with sufficiently light $u/d$ quarks and strange quark at its physical value by the finite size formula. The light quark masses correspond to $m_π= 0.330 - 0.466$ GeV. In the "Asqtad" improved staggered fermion formulation, we measure the $πK$ four-point correlators for both isospin $I=1/2$ and 3/2 channels, and analyze the lattice simulation data at the next-to-leading order in the continuum three-flavor chiral perturbation theory, which enables us a simultaneous extrapolation of $πK$ scattering lengths at physical point. We adopt a technique with the moving wall sources without gauge fixing to obtain the substantiable accuracy, moreover, for $I = 1/2$ channel, we employ the variational method to isolate the contamination from the excited states. Extrapolating to the physical point yields the scattering lengths as $m_πa_{3/2} = -0.0505(19)$ and $m_πa_{1/2} = 0.1827(37)$ for $I=3/2$ and 1/2 channels, respectively. Our simulation results for $πK$ scattering lengths are in agreement with the experimental reports and theoretical predictions, and can be comparable with other lattice simulations. These simulations are carried out with MILC $N_f = 2+1$ flavor gauge configurations at lattice spacing $a \approx 0.15$ fm.

description: The triple negative breast cancer (TNBC) subtype is associated with poor prognosis. Classical chemotherapies are the only FDA-approved therapy available for TNBC patients and are associated with high adverse effects and development of resistance. Thus, identifying novel TNBC therapeutics is a major focus in the field of breast cancer research. Transforming growth factor ? (TGF?) is a secreted factor enriched in the TNBC microenvironment and is a potent inducer of epithelial to mesenchymal transition (EMT), a cellular transdifferentiation process. TGF?-induced EMT plays critical roles in cancer progression, therapy response, and recurrence, partly through the enrichment of tumor-initiating cells with enhanced expression of cluster of differentiation 44 (CD44) protein. Hyaluronic acid, elevated in the tumor stroma, binds to and promotes CD44-regulated signaling enhancing the tumorigenicity of cells making CD44 an ideal therapeutic target in TNBC.Proteoglycan 4 (PRG4) is a glycoprotein found in tissue interfaces where it maintains homeostasis through its lubricating and anti-inflammatory properties. Recombinant human (rh) PRG4 has been found to inhibit CD44-mediated inflammation and proliferation of different epithelial and fibroblast cells in different disease contexts. Considering the parallels of inflammatory diseases and TNBC, I asked the question whether rhPRG4 may suppress TNBC progression My findings in TNBC cells showed that rhPRG4 inhibits TGF?-induced invasion, migration, and anchorage-independent growth in a CD44-dependent manner, with potential involvement of EMT suppression. Using high-throughput drug screen, I identified a wide variety of targeted and classical FDA-approved drugs which show enhanced cytotoxicity when combined with rhPRG4. Bioinformatic analyses indicated that mRNA abundance of PRG4 may act as an independent prognostic marker in breast cancer whose disease predictivity is augmented in CD44high patient cohort. Lastly, proteomics screening followed by in silico analysis aided in identifying several potential downstream effector molecules of rhPRG4 in TNBC cells.The findings in this thesis unveil the novel tumor suppressive role of rhPRG4 with significant promise in the treatment of CD44high TNBC patients. Further studies are required to evaluate the molecular mechanisms of the tumor suppressive activity of rhPRG4, and its development as a potential anti-cancer therapeutic in the management of TNBC and other CD44high cancers.

Adapting RNA interactome capture to explore plant RNA-binding proteins and their RNA targets
Creators: name: Atugala, Dilini M
Publisher: name: Science
Year: 2022
Subjects: subject: Biological Sciences

description: RNA-binding proteins (RBPs) function in every step of RNA metabolism, from synthesis todecay. Thus, the global identification of RBPs and their RNA targets provide important insight intopost transcriptional gene regulation during organismal development and in response toenvironmental cues. To better understand the repertoire of RBPs in Arabidopsis, an RNAinteractome capture (RIC) approach was applied to root and leaf tissues, and to suspensionculture cells. RIC identified 416, 611 and 110 proteins comprising the root, leaf and cell culturemRNA-binding proteomes (RBPomes), respectively. Similar to other RNA interactome studiesthere were a large number of ‘moonlighting’ RBPs (up to 46%) that had activities not related toRNA biology, but rather to processes that included intermediate metabolic pathways,photosynthesis, cytoskeleton, and membrane transporters. These results highlight the overlapbetween interactome studies and reports RBPs that have not been identified in other Arabidopsisstudies. Additionally, the root RIC results provide insight into the RBPome of a tissue that has notbeen reported previously.To understand the responses of cellular RBPs to an abiotic stress, we applied RIC coupledwith stable isotope dimethyl labeling-mass spectrometry to Arabidopsis roots treated withnaphthenic acid fraction compounds (NAFCs) isolated from oil sands tailings pond water. NAFCtreatment resulted in a remodeling of the cellular RBPome, identifying 205 RBPs that increasedin their association with RNA. In addition to RBPsrelated to RNA biology processes, classical stressresponsive proteins were detected and included metabolic enzymes involved in carbohydratemetabolism, suggesting that these RBPs may govern metabolic changes during stress responses.Lastly, an approach was developed and tested for the identification of in vivo target RNAsof RBPs under stringent, denaturing extraction conditions. This immunoprecipitation approachidentified over 300 mRNA targets of a specific RBP (AtGRP7). This approach has the potential tobe used as a simplified option to identify RNA targets over other more advanced techniques suchas crosslinking and immunoprecipitation (CLIP).

description: We study the stability and chaos of three compact objects using post-Newtonian (PN) equations of motion derived from the Arnowitt-Deser-Misner-Hamiltonian formulation. We include terms up to 2.5 PN order in the orbital part and the leading order in spin corrections. We performed numerical simulations of a hierarchical configuration of three compact bodies in which a binary system is perturbed by a third, lighter body initially positioned far away from the binary. The relative importance of the different PN orders is examined. The basin boundary method and the computation of Lyapunov exponent were employed to analyze the stability and chaotic properties of the system. The 1 PN terms produced a small but noticeable change in the stability regions of the parameters considered. The inclusion of spin or gravitational radiation does not produced a significant change with respect to the inclusion of the 1 PN terms.

description: Sometime before 500 BC, a dynamic interaction and exchange network developed among the villages and hamlets in western Nicaragua and northwestern Costa Rica. Traveling across land and canoeing or rafting over the large freshwater lakes and rivers, these peoples voyaged for many hours to trade goods and maintain social and political ties with their neighbors. The range and frequency of these interactions within this region is demonstrated by geochemically sourced ceramic and obsidian artifacts. However, the travel routes along which these artifacts were exchanged remain poorly understood. Geographic information systems (GISs) offer a means to predictively model the optimal travel routes that interconnected the settlements of western Nicaragua and the surrounding regions. In this dissertation, I use a GIS to present a probable simulation of the overland travel infrastructure that facilitated the regional movement of exchange goods during the Tempisque (500 BC – AD 300), Bagaces (AD 300–800), and Sapoá (AD 800–1250) periods. I then discuss and interpret the results of my simulations against the rest of the archaeological record and consider the ethnohistoric accounts of trade and exchange in the region. By interpreting this simulated travel network and the given distribution of exchanged goods within an intersocietal interaction framework, I discuss the role that intraregional movement and mobility played in the evolution of the societies that once thrived in this section of southern Central America. While some exchange goods traveled long distances, most interactions were oriented locally or among neighboring polities.

description: This thesis investigated the effect of novel and eco-friendly nano-sized titanomagnetite particles (NTG) on the mechanical and microstructural properties of cementitious mixtures (i.e., cement paste and mortar). The NTG was synthesised and fully characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), Brunauer-Emmett-Teller (BET), and Zeta potential analysis. The NTG’s characteristics that were obtained confirmed the successful formation of titanomagnetite particles with an average size of 20 nm and a near-spherical morphology. The NTG was added to cement paste and mortar at concentrations of 0.2, 1, 2, and 4% of cement mass. The effects of the incorporation of NTG on the properties of the cementitious mixtures were assessed by evaluating the changes in their compressive strength, flowability, and microstructure. To examine the nature of the interactions between the NTG and the cementitious mixtures, the pore solution (PS) of the pastes incorporating the NTG was extracted and tested for ion concentration measurements. Calcium hydroxide (CH) was also used as a simplified model to understand the nature of possible interactions. The compressive strength data suggested that adding 1 wt% of NTG to the cement pastes and mortars was the optimal amount to achieve the highest level of improvement (20 to 30%) in the compressive strength of the mixtures at different ages. The results showed that the flowability of cement pastes and mortars was not significantly influenced by the addition of NTG up to 1 wt%. The results of isothermal calorimetry TGA and XRD were also generally similar for the samples with and without 1 wt% NTG. Nevertheless, the addition of NTG to cement paste resulted in the refinement of the porosity network. The interaction of NTG with CH and pore solution suggested a robust interaction between various ions and the development of calcium hydroxide on the NTG’s surface. The mechanical performance improvement was possibly caused by pore network refinement and the interactions of NTG with CH and various cations, while the decline in the enhancement level above the 1 wt% addition level was caused by the agglomeration of NTG and an increased water requirement.

description: Beyond lithium-ion batteries (LIB) are required to meet high energy density applications of modern society. Lithium-sulfur (Li-S) battery technology offers a theoretical energy density of 2500 Wh kg-1, which is around 5 times that of existing LIBs. However, at a cell level energy density of >350 Wh kg-1 (where sulfur loading >5 mg cm-2) at room temperature, the Li-S battery demonstrates severe capacity fade, limited cyclability, and poor rate performance. In this thesis, in-situ sulfur cathodes, MoS3 and WS3, are explored as solutions to improve the rate performance of Li-S batteries. Presence of S22- disulfide ligands in MoS3 or WS3, provides an alternative sulfur source to electronically insulating S8. The Li-S battery with MoS3 cathode demonstrated a high reversible capacity of ~1500 mAh g-1 in the first cycle at a rate of 0.3 C, indicating a high sulfur utilization percent of ~89%. Furthermore, when cycled long term at a rate of 2 C (~1000 mAh g-1 in the first cycle), the device was cyclable close to 200 cycles with a capacity fade rate of 0.13% per cycle. The analogous WS3 cathode delivered similar performance. The device was rate capable up to a C-rate of 2C with a specific capacity of ~600 mAh g-1. On long-term cycling the WS3 cathode exhibited a capacity fade rate of ~0.02% per cycle. To increase the sulfur loading tolerance of cathode architecture, a freestanding electrode is investigated. Into this electrode matrix a hybrid MoS2-WS2 anchoring material is incorporated. The novel cathode design maximizes the geometric coverage for anchoring-conversion of polysulfides to restrain shuttle effect at practical sulfur (S) loadings. The strategy presented in chapter 6 prevents the accumulation of polysulfide molecules at a localized site of the anchoring surface. Our systematic analysis (5 – 50 mg cm-2 of S-loadings) reveals that the unique cathode architecture exhibits reversible S-loading tolerance up to 28 mg cm-2. A high initial areal capacity of 32 mAh cm-2 with an area specific energy density of 67 mWh cm-2 is achieved, which is highest among the hybrid composites reported till date. The approach can unlock high S-loading Li-S cells with extended cyclability and rate performance. Finally, we propose a computational aided design principle to screen an ideal surface for polysulfide electrocatalysis.

description: Digital dermatitis (DD) is an infectious disease affecting feet of cattle, a major cause of lameness, significantly impacting productivity and welfare. DD’s emergence in feedlots and its impact on the behaviour and welfare of feedlot cattle is not well understood. This thesis’s aim was to understand the initiation of DD in beef cattle, and its impact on behaviour and welfare. Two studies were conducted, a field study and an experimental study. Impact of DD on behaviour was measured by way of an ear accelerometer and through video recordings, pain and inflammation was assessed with an algometer and infrared camera. Behaviour changes 5 to 2 days before DD diagnosis in heifers. Rumination is depressed, 3% less per day, and inactivity increased, 3% more per day, in heifers afflicted with DD compared to heifers without lesions. Further, daily mean time ruminating was 5% less in cattle with active lesions compared to heifers without lesions. Pain (mechanical nociceptive threshold; MNT), and inflammation (maximum foot temperature; MFT) were measured at the lesion site. MNT was significantly less in feet with DD lesions. MNT was lowest in active lesions, which withstood 8 N and 4 N less pressure than feet without lesions and feet with chronic lesions respectively. A 1 °C increase in MFT was associated with a 0.6 N decrease in MNT. Higher MFT was associated with feet with DD lesions and increased when cattle were lame. Cattle with DD were determined to be more likely to be lame and have altered gait compared to cattle without lesions. Locomotion score, reluctance to bear weight and asymmetric gait were determined to be most predictive of cattle with DD. The final chapter of this thesis describes an experimental model that was used to successfully induce DD lesions in beef calves. An induction rate of 60% was realised within 28 days. Overall, this thesis increased scientific knowledge on the impact of DD on beef cattle, induction, impact on behaviour and locomotion, and pain implications. This thesis provides information that would be useful when developing strategies for early detection, diagnosis of DD and when conducting intervention studies.

description: We study the fragmentation of (light) quarks and gluons to hadrons inside a jet of cone size R. This allows for a more exclusive analysis of fragmentation than is currently the case. The shape of semi-inclusive cross sections in the hadron energy fraction z is described by fragmenting jet functions (FJFs), which we calculate in terms of R and the jet energy E. We introduce a new joint resummation to sum the double logarithms of R and 1-z in the FJFs, which may similarly be applied to initial-state radiation at hadron colliders. Our results at next-to-leading logarithmic order indicate that the resummation of the threshold logarithms of 1-z is already important for z > 0.5 and improves the convergence of perturbation theory. Our framework may be used to analyze LHC and RHIC data and to test and tune Monte Carlo event generators.

description: Virtual reality facilitates a level of immersion impossible with two-dimensional interfaces. Through it, users are able to interact with virtual environments while gaining many of the benefits of interacting within the physical world, most notable of which for my work is the improved perception of depth and the ease of three dimensional interactions. I investigate how virtual reality impacts the study and modeling of plant structures by introducing two applications: Virtual Network Explorer (ViNE) and Tree Wand. ViNE has been designed to aid in the study of complicated networks, such as the intricate vascular structure of flower heads. It allows the user to immerse themselves inside networks, and segment their various components. In Tree Wand a controller is used as a brush to guide the growth of a tree, combining the user's input with a biologically motivated algorithm to simulate a tree’s development. In addition, it provides an interface for the user to manipulate the algorithm’s parameters, allowing a wide variety of tree forms to be represented. Taken together, these applications demonstrate the usefulness of virtual reality in the visual analysis and modeling of plants.

description: We propose a scheme for the dissipative preparation of W-type entangled steady-states of three atoms trapped in an optical cavity. The scheme is based on the competition between the decay processes into and out of the target state. By suitable choice of system parameters, we resolve the whole evolution process and employ the effective operator formalism to engineer four independent decay processes, so that the target state becomes the stationary state of the quantum system. The scheme requires neither the preparation of definite initial states nor the precise control of system parameters and preparation time.

description: Carbon nanofibers (CNFs) have received a great deal of attention as an additive to enhance engineering material properties. In recent years, the use of carbon nanofibers for environmental applications and hydrogen storage has increased due to their high surface area. It is the high cost of CNFs that severely limits their wide application in addition to most of the existing production methods relying on fossil fuels.In the prior art, Dr. M. Zarabian and Dr. Pereira, at the University of Calgary succeeded to develop a net-zero emission technology to produce CNFs from greenhouse gases (GHG) as a feedstock. This M.Sc. thesis aims to evolve the carbonization reactor design to be upscaling-ready by introducing a configuration that could provide uniform reactant concentration, effective transfer of heat generated in exothermic reaction and ease of removing solid fibres. To accomplish this goal, first, the bench-scale method had been fully understood and then new concepts to overcome process bottlenecks were investigated. A new configuration of the reactor to fullfill the requirement was proposed. Then computational fluid dynamics (CFD) was employed to study the flow regime inside the new configuration. Based on CFD results, a prototype of a new configuration was built, and different aspects of process and product were investigated. The results showed that the new reactor configuration to produce carbon nanofiber on sheet metal substrate provides faster nucleation, a more uniform conversion rate and a steady rate of product accumulation compared to monolith configuration. In addition, it shows high up-scalability potential. A prototype of an Autodipping machine was built and successfully employed to impregnate catalysts on the disks. A series of standard characterization procedures for different methods were developed and employed to characterize the products and compare them with commercially available products. The evaluations indicated that both disk and monolith configuration CNF products had comparable and even better features than those of commercial ones.
The Play of Silence and Talk in Difficult Conversations about Literary Texts

description: This inquiry into the visible invisibility of language experience considers how silence may be understood as a generative aspect of difficult conversations about literary texts. Being in silence, being with others in a class discussion setting disrupts the expectation that deep enriching discussions about literature will occur. Hermeneutics begins in disruptions to expectations and familiar understanding so for this inquiry, interpretations of experience are framed by hermeneutic methodological principles. For instructors and students silence disrupts the play of the expected literary studies discourse. Or does it? Can it create the advent of the interrogative, interpretive process of understanding? Can it be eventful? I consulted theoretical perspectives on dialogic pedagogy and spoke with instructors and students about their experiences of silence in literary studies class discussions in higher education. Scholars have noted that literary studies ought to be marked by opportunities for students to engage with difficult topics, in conversation, for students to become competent in literary analysis. That is the curricular context of this inquiry. To interpret what silence means, for instructors and students, is to understand what occurs in understanding and its event. To understand requires positioning and orientation. I can be thrown into silence or choose it. I can be in a shared silence with others or within my solitary meaning of silence. Using the conversation principle of hermeneutic inquiry and the conversation motif of the literary salon, to be in conversation with scholarship, participants, and readers, accompanied by my pauses, interludes, and fermata, I present an understanding of silence’s intentionality to speak of silence’s orientation.

description: In the model of extended non-Abelian tensor gauge fields we have found new metric-independent densities: the exact (2n+3)-forms and their secondary characteristics, the (2n+2)-forms as well as the exact 6n-forms and the corresponding secondary (6n-1)-forms. These forms are the analogs of the Pontryagin densities: the exact 2n-forms and Chern-Simons secondary characteristics, the (2n-1)-forms. The (2n+3)- and 6n-forms are gauge invariant densities, while the (2n+2)- and (6n-1)-forms transform non-trivially under gauge transformations, that we compare with the corresponding transformations of the Chern-Simons secondary characteristics. This construction allows to identify new potential gauge anomalies in various dimensions.

description: Hydrocarbon extraction is deeply connected to questions of power and territory. While many studies have addressed extraction conflicts, few have examined the socio-political foundations of discourses and power behind natural gas extraction in the Amazon with its tremendous ecological, cultural, and economic complexities. Biological conservation, climate change adaptation and development approaches have shed light on indigenous livelihoods and the ecological importance of the Amazon, but tend to overlook their mutual constitutions with strategies of power and knowledge production during extraction negotiations. This study helps to uncover those dynamics by examining the roles of power and knowledge in defining environmental impacts and in influencing social acceptability of hydrocarbon operations across cultural worldviews and a multi-scalar geography. Camisea is the most influential natural gas operation in the Peruvian Amazon. Some praise it as a national example of sustainable and clean energy by defining its impacts to “acceptable” levels. This research examines such definitions of “acceptable” as social constructions, that is to say as an active process in which power and knowledge production dynamics play important (but usually hidden) roles in meaning-making and behavior. Drawing on political ecology with a qualitative design, the project investigates power relationships in Peru’s energy extraction, its political networks and narratives, historical roots, connections and practices, as well as their potential influence on environmental policies and institutional transformations. This research generates theoretical contributions for the political and cultural understanding of energy extraction conflict; applied policy recommendations for hydrocarbon extraction practices; and advocacy-directed input for indigenous communities affected
