This regulation was supported by the expression of downstream genes controlled by FXR, including SHP-1 as the nuclear receptor induced by FXR and involved in bile acid biosynthesis (19), SREBP-1, which is associated with lipid metabolism and negatively regulated by FXR (20), PPARa, which controls SREBP activity and lipid synthesis (21), CYP7A1, which acts as another important regulator of bile acid metabolism inhibited by both FXR and SHP (19,22), and also PEPCK, which regulates the rate-limiting step of hepatic gluconeogenesis and is activated by FXR (23).
When the cholesterol or lanosterol level is high in the cell, the SSDs of HMG-CoA reductase and SREBP cleavage activating protein (SCAP) sense the sterol and cause those proteins to bind to Insig in the ER membrane .
An increase of ER cholesterol above ~5 mol% results in the appearance of PFO-accessible cholesterol and in the disappearance of SREBP-2 in the nucleus controlled by SREBP cleavage-activating protein (SCAP).
Adipogenesis is a well-orchestrated process, in which preadipocyte proliferation, differentiation, and lipid biosynthesis are regulated by a set of factors that include signal transducer and activator of transcription 5A (STAT5A), sterol-regulatory-element-binding protein 1c (SREBP 1c), and peroxisome proliferator-activated receptor gamma (PPAR[gamma]).
Moreover, PI3K/Akt/ mTORC1 signaling conversely exerts crucial effects on the maintaining integrity of lipid rafts by modulating SREBP activation and subsequent cholesterogenesis .

It is an oral small molecule that modulates the SREBP pathway.

To safely make the trip to the Golgi, says Espenshade, cells give each SREBP a chauffeur - the protein SCAP - which binds to SREBP before they both make their way to the Golgi.
The mTORC2 substrate GSK3 (glycogen synthase kinase 3) connects AKT to lipid synthesis since GSK phosphorylates lipogenic transcription factor SREBP (sterol responsive element binding protein) and targets it for protein degradation which is opposed by AKT mediated phosphorylation and inactivation of GSK.
Consistent with these data, it has been previously shown in Ob/Ob mice that increased rates of hepatic fatty acid synthesis are associated with increased nuclear SREBP-1c protein and mRNA levels for known SREBP target genes involved in fatty acid biosynthesis .
