Mitochondrial Outer Membrane Permeability Change and Hypersensitivity to Digitonin Early in Staurosporine-induced Apoptosis [PDF]

open access: yes, 2003
We have shown here that the apoptosis inducer staurosporine causes an early decrease in the endogenous respiration rate in intact 143B.TK- cells. On the other hand, the activity of cytochrome c oxidase is unchanged for the first 8 h after staurosporine ...
