Cellular cholesterol levels are controlled by endoplasmic reticulum (ER) sterol sensing proteins, which include Scap and Insig-1. With cholesterol sufficiency, Insig inhibits the activation of sterol regulatory element binding proteins (SREBPs), key transcription factors for cholesterol and fatty acid biosynthetic genes, by associating with Scap-SREBP complexes to promote their ER retention. He...
Stearoyl CoA desaturase (SCD) is responsible for converting SFA into MUFA and plays an important role in regulating the fatty acid composition of tissues. Although the number of SCD isoforms differs among species, SCD-1 is the predominant isoform expressed in the major lipogenic tissues of all species studied. The SCD-1 gene promoter region has been cloned for several species, including the hum...
BACKGROUND Sterol regulatory element binding protein-2 (SREBP-2) is a membrane-bound transcription factor that upon proteolytic processing can activate the expression of genes involved in cholesterol biosynthesis and uptake. We as well as others have demonstrated that the accumulation of misfolded proteins within the endoplasmic reticulum (ER), a condition known as ER stress, can dysregulate li...
Yellow tea has been widely recognized for its health benefits. However, its effects and mechanism are largely unknown. The current study investigated the mechanism of dietary supplements of large yellow tea and its effects on metabolic syndrome and the hepatic steatosis in male db/db mice. Our data showed that dietary supplements of large yellow tea and water extract significantly reduced water...

In the Gram-negative bacterium Escherichia coli, the E pathway responds to protein misfolding in the envelope. The stress signal is transduced...
The integrity of cell membranes is maintained by a balance between the amount of cholesterol and the amounts of unsaturated and saturated fatty acids in phospholipids. This balance is maintained by membrane-bound transcription factors called sterol regulatory element-binding proteins (SREBPs) that activate genes encoding enzymes of cholesterol and fatty acid biosynthesis. To enhance transcripti...
Microarray studies generating lists of genes with altered expression in placentas from pregnancies complicated with pre-eclampsia (PE) have so far been published in several different studies. Working under the assumption that altered gene expression in PE may be the result of altered expression of regulatory transcription factors (TFs), we looked for over-represented TF-binding sites (TFBSs)-wh...
t cells have been identified as key players in the pathogenesis of type 1 diabetes. however, the exact role of t-cell subpopulations in this pathway is presently unknown. the purpose of this study was to assess the expression pattern of two lineage-specifying transcription factors gata - 3 and t - bet , which are important in t helper type 1 (th1) and th2 cell development , respectively. gene e...
