Activation of the E2F1-CDK1 pathway and cell cycle re-entry contributes to the apoptosis of spiral ganglion cells (SGCs).
CR8 inhibits the E2F1-CDK1 pathway and down-regulates cleaved caspase-9 to potentially protect SGCs from apoptosis.
This is the first study focusing on the E2F1-CDK1 pathway and cell cycle re-entry in SGC apoptosis.
