The Repression of IRS2 Gene by ATF3, a Stress-Inducible Gene, Contributes to Pancreatic β-Cell Apoptosis

IRS2 is a target gene of ATF3, and its repression by ATF3 contributes, at least partly, to the apoptosis induced by ATF3. Because ATF3 is a stress-inducible gene, our work provides a direct link to explain how environmental stress factors can modulate IRS2 gene transcription.
