The helix-loop-helix factors Id3 and E47 are novel regulators of adiponectin.
Adiponectin is an adipocyte-derived cytokine with beneficial effects on insulin sensitivity and the development of atherosclerosis. Id3 is a helix-loop-helix factor that binds to E-proteins such as E47 and inhibits their binding to DNA. Although the helix-loop-helix factor sterol regulatory element binding protein (SREBP)-1c is a known activator of adiponectin transcription, this study provides...
متن کاملSREBP-2-deficient and hypomorphic mice reveal roles for SREBP-2 in embryonic development and SREBP-1c expression.
Cholesterol and fatty acid biosynthesis are regulated by the sterol regulatory element-binding proteins (SREBPs), encoded by Srebf1 and Srebf2. We generated mice that were either deficient or hypomorphic for SREBP-2. SREBP-2 deficiency generally caused death during embryonic development. Analyses of Srebf2(-/-) embryos revealed a requirement for SREBP-2 in limb development and expression of mor...
متن کاملSREBP-1c transcription factor and lipid homeostasis: clinical perspective.
Insulin has long-term effects on glucose and lipid metabolism through its control on the expression of specific genes. In insulin sensitive tissues and particularly in the liver, the transcription factor sterol regulatory element binding protein-1c (SREBP-1c) transduces the insulin signal. SREBP-1c is a transcription factor which is synthetized as a precursor in the membranes of the endoplasmic...
متن کاملMicroarray analyses of SREBP-1a and SREBP-1c target genes identify new regulatory pathways in muscle.
In this study we have identified the target genes of sterol regulatory element binding protein (SREBP)-1a and SREBP-1c in primary cultures of human skeletal muscle cells, using adenoviral vectors expressing the mature nuclear form of human SREBP-1a or SREBP-1c combined with oligonucleotide microarrays. Overexpression of SREBP-1a led to significant changes in the expression of 1,315 genes (655 u...
متن کاملmTORC1 activates SREBP-1c and uncouples lipogenesis from gluconeogenesis.
Correction for “mTORC1 activates SREBP-1c and uncouples lipogenesis from gluconeogenesis,” by Mathieu Laplante and David Sabatini, which appeared in issue 8, February 23, 2010, of Proc Natl Acad Sci USA (107:3281–3282; first published February 18, 2010; 10.1073/pnas.1000323107). The authors note that, on page 3281, left column, second paragraph, the fourth sentence is incorrect in part. “In add...
