In vivo studies showed insulin was able to suppress IRS-2 expression via activation of SREBP-1 in the liver, but this mechanism was not apparent in pancreatic islets from the same animal.

Hepatocytes in primary culture were used to delineate the insulin signalling pathway for induction of SREBP1 gene expression.

Thus acute activation of PKB is sufficient to induce SREBP1 mRNA accumulation in primary hepatocytes, and might be the major signalling event by which insulin induces SREBP1 gene expression in the liver.

Exposure of isolated human adipocytes to insulin enhanced SREBP1 gene expression and promoted its proteolytic cleavage to the active form.

|
Exposure of isolated human adipocytes to tumor necrosis factor-alpha (TNF-alpha) produced a marked and specific decrease in the mRNA encoding the SREBP1c isoform and completely blocked the insulin-induced cleavage of SREBP1 protein.

Previous work showed that acute stimulation of a conditionally active protein kinase B (PKB or cAKT) was sufficient to elicit insulin-like induction of GCK (glucokinase) and SREBP1 (sterol regulatory element-binding protein 1) in hepatocytes [Iynedjian, Roth, Fleischmann and Gjinovci (2000) Biochem.

A PKB-CaaX fusion protein, which can act as a dominant-negative inhibitor of PKB activation in other cells, was shown to be constitutively activated in hepatocytes and to trigger insulin-like induction of GCK and SREBP1.

The stimulation of gene expression by constitutively active PKB-CaaX and inhibition of the insulin effect by ceramide are compatible with a role for PKB in the insulin-dependent induction of GCK and SREBP1.

Thus, alcohol exerts biphasic actions on hepatic insulin signaling, such that low doses activate insulin signaling pathways associated with reduced p55gamma to increase nSREBP-1, whereas high doses of ethanol elevate TRB3 and suppress insulin signaling to decrease SREBP-1.

We studied SCD1 in visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) from morbidly obese patients and their association with insulin resistance, sterol regulatory element binding protein-1 (SREBP-1) and ATPase p97, proteins involved in SCD1 synthesis and degradation.

Conversely, inhibition of SOCS-1 and SOCS-3 in livers of obese diabetic db/db mice by antisense treatment modestly improves insulin sensitivity, but completely normalizes the increased expression of SREBP-1.

Insulin treatment of cultured atrial myocytes stimulated GIRK1 expression 2.68+/-0.12-fold (P<0.01), which was reversed by overexpression of dominant negative SREBP-1.

Insulin-activated gene expression for SREBP-1 is suggested to be involved in stress-augmented hepatic lipogenesis.
