TranscriptomicsMicroarray analysis of surgical liver biopsies from 13 obese (nine with type 2 diabetes) and five control subjects
Hepatic lipid accumulation is an important complication of obesity linked to risk for type 2 diabetes. To identify novel transcriptional changes in human liver which could contribute to hepatic lipid accumulation and associated insulin resistance and type 2 diabetes (DM2), we evaluated gene expressi...

TranscriptomicsProtective unfolded protein response in human pancreatic beta cells transplanted into mice
Islet transplantation exposes beta cells to mild hyperglycemia and to the abnormal environment of the transplant site. These conditions may affect beta cells and induce the expression of genes involved in beta cell damage. Gene expression profile of human beta cells exposed to mild hyperglycemia by ...

TranscriptomicsTranscription profiling of skeletal muscle from diabetic or non-diabetic Mexican Americans with or without a family history of diabetes
Type 2 diabetes mellitus (DM) is characterized by insulin resistance and pancreatic beta-cell dysfunction. In high-risk subjects, the earliest detectable abnormality is insulin resistance in skeletal muscle. Impaired insulin-mediated signaling, gene expression, and glycogen synthesis, and accumulati...

TranscriptomicsHuman skeletal muscle - type 2 diabetes and family history positive individuals - Mexican American
Type 2 diabetes mellitus (DM) is characterized by insulin resistance and pancreatic beta-cell dysfunction. In high-risk subjects, the earliest detectable abnormality is insulin resistance in skeletal muscle. Impaired insulin-mediated signaling, gene expression, and glycogen synthesis, and accumulati...

TranscriptomicsIncreased SRF Transcriptional Activity is a Novel Signature of Insulin Resistance in Humans and Mice
Insulin resistance in skeletal muscle is a key phenotype associated with type 2 diabetes (T2D) and is even present in offspring of diabetic parents. However, molecular mediators of insulin resistance remain unclear. We find that the top-ranking gene set in expression analysis of muscle from humans w...

TranscriptomicsExpression of Splicing Factor Genes is Reduced in Human Obesity and Contributes to Enhanced Lipogenesis
Alternative mRNA splicing provides transcript diversity and has been proposed to contribute to several human diseases. Here, we demonstrate that expression of genes regulating RNA processing is decreased in both liver and skeletal muscle of obese humans. To determine the metabolic impact of reduced ...
