Endotoxemia-mediated activation of acetyltransferase P300 impairs insulin signaling in obesity
Elevated plasma LPS levels have been associated with insulin resistance. Here Cao et al. show that LPS induces ER stress and P300 activity via the XBP1/IRE1 pathway. P300 acetylates IRS1/2 and inhibits its binding with the insulin receptor. The consequent impairment of insulin signaling can be rescu...

| Sumario: | Elevated plasma LPS levels have been associated with insulin resistance. Here Cao et al. show that LPS induces ER stress and P300 activity via the XBP1/IRE1 pathway. P300 acetylates IRS1/2 and inhibits its binding with the insulin receptor. The consequent impairment of insulin signaling can be rescued by pharmacological inhibition of P300. |
