Obesity is tightly linked to hepatic steatosis and insulin resistance. One feature of this association is the paradox of selective insulin resistance: insulin fails to suppress hepatic gluconeogenesis but activates lipid synthesis in the liver. How lipid accumulation interferes selectively with some...

Diet-induced obesity (DIO) predisposes individuals to insulin resistance, and adipose tissue has a major role in the disease. Insulin resistance can be induced in cultured adipocytes by a variety of treatments, but what aspects of the in vivo responses are captured by these models remains unknown. W...

Background: Insulin's effect on protein synthesis (translation of transcripts) and post-translational modifications, especially those involving reversible modifications such as phosphorylation of various signaling proteins, are extensively studied. On the other hand, insulin's effect on the transcri...

Effect of insulin on the cardiomyocyte global transcriptome and RNAs recruited to polysomes.
For comparison with endothelin-1

The objective of this study was to investigate the link between signaling-network activation and transcriptional regulation downstream of tumor necrosis factor (TNF), epidermal growth factor (EGF), and insulin. Microarrays were used to capture the transcriptional responses to TNF, EGF, and insulin a...

Transcriptional profiling of insulin exposed H4IIE cells at different time points (6h-24h) to 100 nM insulin, with untreated solvent control cells (blanks). The central role of hepatic insulin resistance in pandemic metabolic diseases urges investigation of the underlying mechanisms of its developme...

Cellular and tissue defects associated with insulin resistance are coincident with transcriptional abnormalities and are improved after insulin sensitization with thiazolidinedione (TZD) PPAR? ligands. We transcriptionally profiled 364 biopsies gathered from 72 human subjects harvested before and af...

Insulin and IGF-1 promote adipocyte differentiation via complex and overlapping signalling networks. Here we used microarray analysis of brown preadipocytes derived from wild-type and insulin receptor substrate (IRS) knockout (KO) animals, which exhibited progressively impaired differentiation, to ...

Compared mRNA expression between control and insulin treated cells. HT29 cells were treated with 100nM Insulin for 24h. The RT2 Profiler PCR Arrays PAHS-30C (SA Biosciences, MD, USA) was designed to analyze 84 genes related to human insulin signaling pathway. The RT-PCR was carried out using an ABI ...

Glycerol kinase (GK) is at the interface of fat and carbohydrate metabolism and has been implicated in insulin resistance and type 2 diabetes mellitus (T2DM). To define GK's role in insulin resistance, we examined gene expression in brown adipose tissue in a glycerol kinase (Gyk) knockout (KO) mouse...
