Abstract:
The present disclosure describes an unexpected and novel insight into hepatic insulin resistance through the description of the ability of VEGF inhibitors to revert hyperglycemia and hyperinsulimenia in murine Type 2 diabetes mellitus models through modulation of a HIF-2α-IRS-2 axis operative in hepatocytes. As such, the data of the present disclosure uncover a novel pathway regulating hepatic IRS-2 expression, and identify VEGF inhibitors as an FDA-approved class of therapeutics capable of increasing liver IRS levels and ameliorating Type 2 diabetes mellitus. Accordingly, this disclosure identifies stabilization of HIF-2α as a robust method for improving glucose metabolism. The disclosure provides embodiments of a method of modulating the level of glucose metabolism of a mammalian cell, comprising: contacting a mammalian cell with an effective amount of a composition, where the composition can modulate the levels of HIF-2α and IRS-2 activity in said cell, thereby modulating the level of glucose metabolism by said cell. The disclosure also provides embodiments of a pharmaceutical composition and methods for their use for the treatment of Type 2 diabetes in an animal or human subject, the method comprising administering to an animal or human subject a effective amount of a pharmaceutically acceptable composition, the composition, when administered to an animal or human subject, increasing the activity of HIF-2α and IRS-2 in the animal or human subject, thereby reducing the level of blood glucose in the animal or human subject.
