The TNF-α-FABP4-Dhhc7 Axis Mediates Olanzapine-Induced Insulin Resistance in Rats and Humans. (PubMed, Clin Exp Pharmacol Physiol)
In summary, our study demonstrated that long-term exposure to olanzapine increases circulating plasma levels of TNF-α, thus leading to increased expression of FABP4 protein in white adipose tissue and subsequently inhibiting Dhhc7expression, which correspondingly leads to reduced membrane translocation of GLUT4 and consequent insulin resistance. In conclusion, this study elucidated the signalling pathway through which olanzapine inhibits GLUT4 membrane transport via the TNF-α/FABP4/Dhhc7 axis, thus ultimately leading to insulin resistance.
