RIP140 regulation of glucose transport
Inhibition of RIP140 increases glucose transport. Compounds that inhibit RIP140 expression or activity are useful for treating disorders associated with aberrant glucose transport (e.g., diabetes), treating obesity, increasing metabolism (e.g., fatty acid metabolism), and increasing brown fat.
1. A method for increasing glucose transport in a cell in vitro, the method comprising:
providing a cell in vitro; and
contacting the cell with a small inhibitory RNA (siRNA) that inhibits expression of a RIP140 polypeptide, thereby increasing glucose transport in the cell.
2. The method of claim 1 , wherein the siRNA comprises a sequence selected from SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3, and SEQ ID NO:4.
3. The method of claim 1 , wherein the siRNA inhibits RIP140-mediated suppression of expression of a gene.
4. The method of claim 1 , wherein the cell is an adipocyte.
