Many of these cell populations are crucial for homeostasis and/or exercise response. As for his career, Smith is now a postdoctoral researcher at Mount Sinai where he studies stochastic gene expression. For instance, immune cells promote inflammation in response to exercise and injury 1 , FAPs secrete IL−6, which promotes the differentiation of myogenic cells 11 , and endothelial cells secrete multiple myogenic and/or anti-apoptotic factors 12. Sign Up. It is not possible to directly measure the detailed interaction rates needed to parameterize a model, and there is only a limited amount of experimental evidence available to constrain possible pathways, with almost all of it gathered from in vitro studies of purified coat proteins.

Gregory Smith, Mount Sinai School of Medicine, Neurology Department, Faculty Member. Medicine - Clinical Immunology. These muscle fibers include several fiber types of differing metabolic and functional properties 2-4. Besides multinucleated fibers, skeletal muscle contains many mononuclear cells, such as immune cells, endothelial cells, satellite cells, and FAPs. The resulting fits suggest three different in vitro assembly mechanisms for the three systems, with HPV capsids fitting a model of assembly via a nonnucleation-limited pathway of accumulation of individual capsomers while HBV and CCMV capsids fit similar but subtly different models of nucleation-limited assembly through ensembles of pathways involving trimer-of-dimer intermediates. Postdoctoral Researcher at Icahn School of Medicine at Mount Sinai. Transcriptome exercise studies using bulk tissue analysis do not resolve changes in individual cell-type proportion or gene expression. Learn more about Gregory Smith, Mount Sinai Hospital including contact information, career history, news and intelligence. Virus capsids make an excellent model system for such questions because they typically have few distinct components, making them amenable to in vitro and modeling studies, yet their assembly can involve complex networks of possible reactions that cannot be resolved in detail by any current experimental technology. Gregory Smith. Studies Biology, Computational Biology, and Biological Sciences. Crucially, muscle fibers secrete myokines, which both act locally within muscle tissue as well as influence other organs and tissues via hormone-like signaling 10. PhD Candidate @ Carnegie Mellon University. Robert M Smith, CLINICAL INSTRUCTOR at Mount Sinai Health System, specializing in . We bypass that limitation by applying analytical models of nucleic acid effects to adjust kinetic rate parameters learned from in vitro data to see how these adjustments, singly or in combination, might affect fine-scale assembly progress.

As they ready themselves to receive the Torah, God instructs Moses to make a firm boundary around the base of Mount Sinai, which the Israelites are not to cross. While slow-twitch (or Type I) muscle fibers possess high oxidative capacity, fast-twitch (or Type II) muscle fibers have a high glycolytic capacity and are capable of supplying more power than Type I fibers 2-4.

Due to the complex interplay between these cell types and their influence on muscle fibers, changes in cells within the skeletal muscle such as FAPs and satellite cells are implicated in degenerative muscle disease (e.g., muscular dystrophy, heterotopic ossification) as well as aging-related fibrosis and reduced muscle regeneration 1,13,14 . The major challenge of such work is computational: simulating fine-scale assembly pathways on the scale and in the parameter domains of real viruses is far too computationally costly to allow for explicit models of nucleic acid interaction. ...

The so-called dispersion parameter controls this scaling, and our analysis suggests that the dispersion parameter is a continually decreasing function of the mean, as opposed to current approaches that impose an asymptotic value to the dispersion parameter at moderate mean read counts.

Gregory Smith. Skip to main content Summary: Gregory Goodman is 60 years old and was born on 03/30/1960. Virus capsid assembly has attracted considerable interest from the biophysical modeling community as a model system for complicated self-assembly processes. Faculty Profiles. Here, we apply the improved data-fitting approach to three capsid systems—human papillomavirus (HPV), hepatitis B virus (HBV), and cowpea chlorotic mottle virus (CCMV)—to assess both the range of pathway types the methods can learn and the diversity of assembly strategies in use between these viruses. Gregory Smith, Actor: Everwood. The work demonstrates how computer simulations can help us understand how assembly might differ between the in vitro and in vivo environments and what features of the cellular environment account for these differences.

Myokines may be responsible for the immune-, metabolism-, and cognition-related benefits of physical activity, as well as the chronic diseases that are caused by lack of physical activity (insulin resistance, cardiovascular disease, etc.) Log In. Gregory Edward Smith was born in Toronto, Ontario, to Terrea (Oster), an American-born actress, and Maurice Smith, a British-born film producer. We evaluate the merits of data-fitting methods based on derivative-free optimization (DFO) relative to gradient-based methods used in prior work. Here, we propose a mechanistic justification to model mRNAseq as a binomial process, with data from technical replicates given by a bino-mial distribution, and data from biological replicates well-described by a beta-binomial distribution. Gregory Smith Contact Details. To improve the understanding of skeletal muscle cell types and their transcriptional signatures, we studied human and mouse skeletal muscle mononuclear cells by single-cell RNA-sequencing and single human muscle fiber subtypes by RNA-seq. Court Records found View. More informative data sources lead to high-quality fits for all methods, but DFO methods show substantial advantages on less informative data sources that better represent current experimental practice. Medicine - … Simulation methods have proven valuable for characterizing the space of possible kinetics and mechanisms of capsid assembly, but they have so far been able to say little about the assembly kinetics or pathways of any specific virus. He is affiliated with Mount Sinai Beth Israel, New York Eye and Ear Infirmary of Mount Sinai, and Mount Sinai West. 10. He continues to work full time offering all aspects of general practice.

Medicine - Gastroenterology. The resulting simulations exhibit surprising behavioral complexity, with distinct effects often acting synergistically to drive efficient assembly and alter pathways relative to the in vitro model. We investigated the gene expression patterns of skeletal muscle cells using RNA-seq of subtype-pooled single human muscle fibers and single cell RNA-seq of mononuclear cells from human vastus lateralis, mouse quadriceps, and mouse diaphragm. The cell-type gene signatures provide the means to use computational methods to identify cell-type level changes in bulk studies.

A main application for mRNA sequencing (mRNAseq) is determining lists of differentially-expressed genes (DEGs) between two or more conditions. The underlying probability model used to describe mRNAseq data is central to deriving DEGs, and not surprisingly most softwares use different models and assumptions to analyze mRNAseq data. See, not all us blondes are dumber than rock salt before we become senile but what grown up Greg is doing is: Smith is now a postdoctoral researcher at Mount Sinai … His brother is actor Douglas Smith.

We demonstrate good agreement of this model with two large datasets. Search. Furthermore, the tran-scriptomic response to physical activity is different in each fiber-type as each fiber-type responds differently to different modes of exercise 8,9. The environment of a living cell is vastly different from that of an in vitro reaction system, an issue that presents great challenges to the use of in vitro models, or computer simulations based on them, for understanding biochemistry in vivo. Previous to Gregory's current city of Peoria, AZ, Gregory Goodman lived in Mount Sinai, NY, Commack NY, and Coram NY.
