摘要

Activation of phosphatidylinositol (PI) 3-kinase, protein kinase A (PKA) and protein kinase C (PKC) is associated with the survival effect elicited by PDGF-AB and TGF-beta1 against the apoptotic inducer 2-deoxy-D-ribose (dRib) in the fat body cell line, IPLB-LdFB, from the insect Lymantria dispar. dRib induces apoptosis and provokes mitochondrial membrane depolarization (MMD). The antioxidant N -acetyl-L-cysteine annuls only the first effect. These findings suggest that apoptosis and MMD are provoked by two different mechanisms, and that dRib induces apoptosis by oxidative stress. Copyright 2001 Academic Press.
