Versican G1 Domain and V3 Isoform Overexpression Results in Increased Chondrogenesis in the Developing Chick Limb In Ovo
Authors: Hudson Karla S. , Andrews Kristen , Early June , Mjaatvedt Corey H. , Capehart Anthony A. 
Published: September 2010

AbstractPrevious work has shown that versican proteoglycan is highly expressed in the extracellular matrix of precartilage limb mesenchyme. Although much of versican's role in chondrogenesis has been attributed to its glycosaminoglycan complement, N‐ and C‐terminal G1 and G3 domains of versican have been shown to possess distinct functions when expressed ectopically. This study was undertaken to test the hypothesis that overexpression of the versican G1 domain and short V3 isoform, comprised of only G1 and G3, in the chick wing in ovo would result in increased chondrogenesis, suggesting function for discrete versican domains in limb skeletal development. Recombinant adenoviruses encoding G1 and V3 proteins were microinjected into proximal HH19–25 chick wing buds which resulted in significant enlargement of humeral primordia at HH35. Enhanced cartilage deposition appeared due to increased chondrogenic aggregation as a result of recombinant G1 or V3 overexpression, further implicating versican in early stages of limb development.

Published: September 2010

AbstractObjectiveHypoxia is a prominent feature in rheumatoid arthritis (RA) synovium. However, its contribution to the pathogenesis of RA remains unclear. We undertook this study to systematically characterize the changes in gene expression induced by hypoxia in synovial fibroblasts.MethodsWe used microarray expression profiling in paired normoxic and hypoxic cultures of healthy synovial fibroblasts (HSFs) and RA synovial fibroblasts (RASFs). We used Student's paired t‐test with Benjamini and Hochberg multiple testing correction to determine statistical significance. Validation of microarray data was performed by quantitative real‐time reverse transcription–polymerase chain reaction analysis of selected genes. Biologic pathways differentially modulated by hypoxia in RASFs or HSFs were identified using unsupervised Ingenuity Pathways Analysis.ResultsHypoxia induced significant changes in the expression of a large group of genes in both HSFs and RASFs. In RASFs, we observed a lower number of hypoxia‐regulated genes and partial differences in their functional categories. The number of differentially expressed genes in RASFs compared with HSFs was significantly increased by hypoxia. Multiple gene sets involved in energy metabolism, intracellular signal transduction, angiogenesis, and immune and inflammatory pathways were significantly modified, the last in both proinflammatory and antiinflammatory directions.ConclusionThese data demonstrate that hypoxia induces significant changes in gene expression in HSFs and RASFs and identify differences between RASF and HSF profiles. The hypoxia‐induced gene expression program in synovial fibroblasts identifies new factors and pathways relevant to understanding their contribution to the pathogenesis of chronic arthritis.
The mechanics of development: Models and methods for tissue morphogenesis
Authors: Gjorevski Nikolce , Nelson Celeste M. 
Published: September 2010

AbstractEmbryonic development is a physical process during which groups of cells are sculpted into functional organs. The mechanical properties of tissues and the forces exerted on them serve as epigenetic regulators of morphogenesis. Understanding these mechanobiological effects in the embryo requires new experimental approaches. Here we focus on branching of the lung airways and bending of the heart tube to describe examples of mechanical and physical cues that guide cell fate decisions and organogenesis. We highlight recent technological advances to measure tissue elasticity and endogenous mechanical stresses in real time during organ development. We also discuss recent progress in manipulating forces in intact embryos. Birth Defects Research (Part C) 90:193–202, 2010. © 2010 Wiley‐Liss, Inc.
Cryopreservation of mammalian embryos: Advancement of putting life on hold
Authors: Tsang Wai Hung , Chow King L. 
Published: September 2010

AbstractRodent transgenesis and human‐assisted reproductive programs involve multistep handling of preimplantation embryos. The efficacy of production and quality of results from conventionally scheduled programs are limited by temporal constraints other than the quality and quantities of embryos per se. The emergence of vitrification, a water ice‐free cryopreservation technique, as a reliable way to arrest further growth of preimplantation embryos, provides an option to eliminate the time constraint. In this article, current and potential applications of cryopreservation to facilitate laboratory animal experiments, colony management, and human‐assisted reproductive programs are reviewed. Carrier devices developed for vitrification in the last two decades are compared with an emphasis on their physical properties that infer cooling rate of samples and sterility assurance. Biological impacts of improved cryopreservation on preimplantation embryos are also discussed. Birth Defects Research (Part C) 90:163–175, 2010. © 2010 Wiley‐Liss, Inc.
Imaging modalities to assess structural birth defects in mutant mouse models
Authors: Tobita Kimimasa , Liu Xiaoqin , Lo Cecilia W. 
Published: September 2010

AbstractAssessment of structural birth defects (SBDs) in animal models usually entails conducting detailed necropsy for anatomical defects followed by histological analysis for tissue defects. Recent advances in new imaging technologies have provided the means for rapid phenotyping of SBDs, such as using ultra‐high frequency ultrasound biomicroscopy, optical coherence tomography, micro‐CT, and micro‐MRI. These imaging modalities allow the detailed assessment of organ/tissue structure, and with ultrasound biomicroscopy, structure and function of the cardiovascular system also can be assessed noninvasively, allowing the longitudinal tracking of the fetus in utero. In this review, we briefly discuss the application of these state‐of‐the‐art imaging technologies for phenotyping of SBDs in rodent embryos and fetuses, showing how these imaging modalities may be used for the detection of a wide variety of SBDs.

Metabolic engineering of resveratrol and other longevity boosting compounds
Authors: Wang Yechun , Chen Hui , Yu Oliver 
Published: September 2010

AbstractResveratrol, a compound commonly found in red wine, has attracted many attentions recently. It is a diphenolic natural product accumulated in grapes and a few other species under stress conditions. It possesses a special ability to increase the life span of eukaryotic organisms, ranging from yeast, to fruit fly, to obese mouse. The demand for resveratrol as a food and nutrition supplement has increased significantly in recent years. Extensive work has been carried out to increase the production of resveratrol in plants and microbes. In this review, we will discuss the biosynthetic pathway of resveratrol and engineering methods to heterologously express the pathway in various organisms. We will outline the shortcuts and limitations of common engineering efforts. We will also discuss briefly the features and engineering challenges of other longevity boosting compounds.
Phytochemical Analysis andin vitroFree‐Radical‐Scavenging Activities of the Essential Oils from Leaf and Fruit ofMelaleuca leucadendraL.
Authors: Pino Jorge A. , Regalado Erik L. , Rodríguez José L. , Fernández Miguel D. 
Published: September 2010

AbstractThe phytochemical profile ofMelaleuca leucadendraL. leaf and fruit oils from Cuba was investigated by GC and GC/MS. Forty‐one and sixty‐four volatile compounds were identified and quantified, accounting for 99.2 and 99.5% of the leaf‐oil and fruit‐oil total composition, respectively. The main components were 1,8‐cineol (43.0%), viridiflorol (24.2%),α‐terpineol (7.0%),α‐pinene (5.3%), and limonene (4.8%) in the leaf oil, and viridiflorol (47.6%), globulol (5.8%), guaiol (5.3%), andα‐pinene (4.5%) in the fruit oil. The antioxidant capacity of these essential oils was determined by three differentin vitroassays (2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical, thiobarbituric acid reactive species (TBARS), and 2,2′‐Azinobis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS) radical cation), and significant activities were evidenced for all of them.
Early‐Season Headspace Volatiles from Apple and Their Effect on the Apple Blossom Weevil Anthonomus pomorum
Authors: Piskorski Rafal , Dorn Silvia 
Published: September 2010

AbstractApple volatiles emitted at early phenological stages are little investigated, although they may influence behavior of early‐season pests. The apple blossom weevil Anthonomus pomorum is a herbivore pest of orchards in Europe. It colonizes apple trees in early season and oviposits into developing flower buds, often leading to economic damage. Using in situ radial diffusive sampling and thermal desorption, followed by GC/MS analysis, headspace volatiles from apple twigs with flower buds at three early phenological tree stages were identified and quantified. The volatile blend consisted of 13 compounds for the first, and increased to 15 compounds for the third phenological stage sampled. These blends included benzenoids, terpenes, and derivatives of fatty acids. A recombined synthetic blend served as the odor source in a still‐air dual‐choice olfactometer bioassay, in which individual male and female weevils were tested. Results from this behavioral test document an attraction of both sexes to odors of their host plant, suggesting that apple volatiles emitted in early season serve as olfactory cues for host location of A. pomorum in the field.
Dicationic Tellurium Analogues of the Classic N‐Heterocyclic Carbene
Authors: Dutton Jason L. , Ragogna Paul J. 
Published: September 2010

AbstractThe synthesis and comprehensive characterization of the first dicationic tellurium analogues of N‐heterocyclic carbenes (NHCs) has been reported, in both the +2 and +4 oxidation states. For the +2 oxidation state, a base‐stabilized form of TeCl2 is used as the starting material. The dications are isolated by means of halide metathesis and the solid‐state structures confirm the previously calculated diimine bonding arrangement. For TeIV, a diamine is used in a high‐yielding dehydrohalogen coupling reaction from TeCl4. The dicationic NHC analogue is isolated in a base‐stabilized form through halide abstraction and subsequent coordination by pyridine.
