Description
While acute aerobic and resistance exercise stimulate a number of shared genes, each exercsie mode stimlutes a number of uniquely responsive genes, thus highlighting that different forms of exercise facilitate distinct molecular responses in skeletal muscle. Overall design: Randomized, counter-balanced, cross-over design (n=6) in which subjects performed an acute bout aerobic and resistance exercise separated by ~1 week.
Publication Title
Transcriptome response of human skeletal muscle to divergent exercise stimuli.

Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
Serum levels of interleukin-8 (IL-8) are increased in the serum of people with pancreatic cancer and associated with the loss of body weight and low muscle mass. We have identified that systemic (intraperitoneal) injection of IL-8 into mice induces significant skeletal muscle atrophy. Transcriptional profiling of muscle harvested from these same mice identified the genes and biological processes associated with this IL-8 induced atrophy including gene clusters related to chromatin modification, muscle cell differentiation, and ubiquitin ligase complex.

Description
Human pluripotent stem cells (hPSCs) are potential sources of cells for modeling disease and development, drug discovery, and regenerative medicine. However, it is important to identify factors that may impact the utility of hPSCs for these applications. In an unbiased analysis of 205 hPSC and 130 somatic samples, we identified hPSC-specific epigenetic and transcriptional aberrations in genes subject to X chromosome inactivation (XCI) and genomic imprinting, which were not corrected during directed differentiation. We also found that specific tissue types were distinguished by unique patterns of DNA hypomethylation, which were recapitulated by DNA demethylation during in vitro directed differentiation. Our results suggest that verification of baseline epigenetic status is critical for hPSC-based disease models in which the observed phenotype depends on proper XCI or imprinting, and that tissue-specific DNA methylation patterns can be accurately modeled during directed differentiation of hPSCs, even in the presence of variations in XCI or imprinting.
