- Uttarwar L, Gao B, Ingram A, Krepinsky J. SREBP-1 activation by glucose mediates TGF-? upregulation in mesangial cells. Am J Physiol Renal Physiol. 2012;302:F329-41 pubmed publisher..Activated SREBP-1 binds to the TGF-? promoter, resulting in TGF-?1 upregulation in response to HG. SREBP-1 thus provides a potential novel therapeutic target for the treatment of diabetic nephropathy. ..

Identification of CCAAT/enhancer-binding protein beta as an SREBP-1C target. J Biol Chem. 2002;277:35625-34 pubmed..Thus, some of the effects of insulin and/or SREBP-1c in mature fat cells might require C/EBPbeta or C/EBPdelta as transcriptional relays. ..
- Xu G, Muller O, Stange E, Fuchs M. Impaired regulation of sterol regulatory element binding protein 2 in cholesterol gallstone-susceptible mice. Biochim Biophys Acta. 2004;1688:274-9 pubmedLipid synthesis is under tight transcriptional control involving sterol regulatory element binding proteins (SREBP1, SREBP2)...
- Moon Y, Hammer R, Horton J. Deletion of ELOVL5 leads to fatty liver through activation of SREBP-1c in mice. J Lipid Res. 2009;50:412-23 pubmed publisher..These studies demonstrate that reduced ELOVL5 activity leads to hepatic steatosis, and endogenously synthesized PUFAs are key regulators of SREBP-1c activation and fatty acid synthesis in livers of mice. ..

Hepatology. 2012;55:437-46 pubmed publisher..In conclusion, ethanol-induced up-regulation of lipin-1 gene expression is mediated through inhibition of AMPK and activation of SREBP-1. ..
- Pols T, Ottenhoff R, Vos M, Levels J, Quax P, Meijers J, et al. Nur77 modulates hepatic lipid metabolism through suppression of SREBP1c activity. Biochem Biophys Res Commun. 2008;366:910-6 pubmed..Taken together, our study demonstrates that Nur77 modulates hepatic lipid metabolism through suppression of SREBP1c activity. ..
- Seo Y, Chong H, Infante A, Im S, Xie X, Osborne T. Genome-wide analysis of SREBP-1 binding in mouse liver chromatin reveals a preference for promoter proximal binding to a new motif. Proc Natl Acad Sci U S A. 2009;106:13765-9 pubmed publisher..SREBP-1 bound not only to many well-characterized SREBP-1 target genes but to several other previously unknown targets in lipid and carbohydrate metabolism as well as many putative target genes in other diverse biological pathways. ..
- Lee G, Jang H, Lee J, Huh J, Choi S, Chung J, et al. PIASy-mediated sumoylation of SREBP1c regulates hepatic lipid metabolism upon fasting signaling. Mol Cell Biol. 2014;34:926-38 pubmed publisher..Together, these data suggest that PKA-induced SREBP1c sumoylation by PIASy is a key regulatory mechanism to turn off hepatic lipogenesis during nutritional deprivation. ..
