Regulation of proglucagon transcription by activated transcription factor (ATF) 3 and a novel isoform, ATF3b, through the cAMP-response element/ATF site of the proglucagon gene promoter.

Glucagon, the second major glucose-regulated hormone in the control of glucose homeostasis, functions as a counter-regulator to insulin and is specifically produced by the pancreatic alpha cells. Its excessive biosynthesis and secretion is associated with diabetes mellitus. The expression of the proglucagon gene has been demonstrated to be regulated by a cAMP-dependent pathway through cAMP-resp...

Mechanical control of cAMP signaling through integrins is mediated by the heterotrimeric Galphas protein.

Mechanical stresses that are preferentially transmitted across the cell surface via transmembrane integrin receptors activate gene transcription by triggering production of intracellular chemical second messengers, such as cAMP. Here we show that the sensitivity of the cAMP signaling pathway to mechanical stresses transferred across beta1 integrins is mediated by force-dependent activation of t...

TGF-β Signaling Regulates Pancreatic β-Cell Proliferation through Control of Cell Cycle Regulator p27 Expression

Proliferation of pancreatic β-cells is an important mechanism underlying β-cell mass adaptation to metabolic demands. Increasing β-cell mass by regeneration may ameliorate or correct both type 1 and type 2 diabetes, which both result from inadequate production of insulin by β-cells of the pancreatic islet. Transforming growth factor β (TGF-β) signaling is essential for fetal development and gro...

miR-320 regulates inflammation in EAE through interference with TGF-β signaling pathway

Background: MicroRNAs are small noncoding RNAs that regulate gene expression and involve in many cellular and physiological mechanisems. Recent studies have revealed that dysregulation of microRNAs might contribute to autoimmune disorders such as multiple sclerosis. Based on these findings, we examined the potential role of miR-320 isoforms, miR-320-3p and miR-320-5p, in the context of autoimmu...

Swimming training alleviated insulin resistance through Wnt3a/β-catenin signaling in type 2 diabetic rats

Objective(s): Increasing evidence suggests that regular physical exercise improves type 2 diabetes mellitus (T2DM). However, the potential beneficial effects of swimming on insulin resistance and lipid disorder in T2DM, and its underlying mechanisms remain unclear. Materials and Methods: Rats were fed with high fat diet and given a low dosage of Streptozotocin (STZ) to induce T2DM model, and su...
