Mitochondria in DRG neurons undergo hyperglycemic mediated injury through Bim, Bax and the fission protein Drp1.

Dorsal root ganglia (DRG) neurons degenerate in diabetic neuropathy (DN) and exhibit mitochondrial damage. We studied mitochondria of cultured DRG neurons exposed to high glucose as an in vitro model of DN. High glucose sequentially increases the expression, activation and localization of the pro-apoptotic proteins Bim and Bax and the mitochondrial fission protein dynamin-regulated protein 1 (Drp1). High glucose causes association of Drp1/Bax, similar to other apoptotic stimuli. Collectively, these events promote mitochondrial fragmentation and reduce mitochondrial number, suggestive of apoptotic mitochondrial fission. Drp1 is also upregulated in DRG from experimentally diabetic rats, suggesting a role for mitochondrial fission in DN. Insulin-like growth factor-I (IGF-I) protects high glucose-treated DRG neurons by preventing mitochondrial accumulation of Bim and Bax but does not modulate Drp1 expression or localization. We propose that mitochondria are compromised by convergence of Bim/Bax proteins with Drp1, which contributes to high glucose-induced injury in DRG neurons.[1]
