In vivo Analysis of H2AX Phosphorylation Induced by γ-Radiation
ABSTRACT Background and Objectives: Exposure to ionizing radiation in modern societies is inevitable and can cause a variety of adverse health effects such as cancer and birth defects. Therefore, a reliable, repeatable and sensitive method is required for evaluation of radiation exposure. The aim of this study was to determine the amount of hist...
متن کاملInsulin-induced phosphorylation of FKHR (Foxo1) targets to proteasomal degradation.
Forkhead transcription factor FKHR (Foxo1) is a key regulator of glucose homeostasis, cell-cycle progression, and apoptosis. It has been shown that FKHR is phosphorylated via insulin or growth factor signaling cascades, resulting in its cytoplasmic retention and the repression of target gene expression. Here, we investigate the fate of FKHR after cells are stimulated by insulin. We show that in...
متن کاملGlucose-induced phosphorylation of the insulin receptor. Functional effects and characterization of phosphorylation sites.
Elevated glucose concentrations have been reported to inhibit insulin receptor kinase activity. We studied the effects of high glucose on insulin action in Rat1 fibroblasts transfected with wild-type human insulin receptor (HIRcB) and a truncated receptor lacking the COOH-terminal 43 amino acids (delta CT). In both cell lines, 25 mM glucose impaired receptor and insulin receptor substrate-1 pho...
متن کاملPrep1 Controls Insulin Glucoregulatory Function in Liver by Transcriptional Targeting of SHP1 Tyrosine Phosphatase
OBJECTIVE We investigated the function of the Prep1 gene in insulin-dependent glucose homeostasis in liver. RESEARCH DESIGN AND METHODS Prep1 action on insulin glucoregulatory function has been analyzed in liver of Prep1-hypomorphic mice (Prep1(i/i)), which express 2-3% of Prep1 mRNA. RESULTS Based on euglycemic hyperinsulinemic clamp studies and measurement of glycogen content, livers from...
متن کاملSTIM1 Phosphorylation at Y361 Recruits Orai1 to STIM1 Puncta and Induces Ca2+ Entry
Store-operated Ca2+ entry (SOCE) mediates the increase in intracellular calcium (Ca2+) in endothelial cells (ECs) that regulates several EC functions including tissue-fluid homeostasis. Stromal-interaction molecule 1 (STIM1), upon sensing the depletion of (Ca2+) from the endoplasmic reticulum (ER) store, organizes as puncta that trigger store-operated Ca2+ entry (SOCE) via plasmalemmal Ca2+-sel...
