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-β1 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).

Abstract
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-β1 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. © 2001 Academic Press.Pubblicazioni consigliate
