Meanwhile, we found that apoptosis inducing factor (AIF) and cytochrome C (Cyc) were released from mitochondria to cytoplasm after 60 nM shFAS infection via immunofluorescent staining (Figures 6(a) and 6(b)) and Western blotting (Figures 6(c) and 6(d)). The gene discussed is CYCS; the disease is infection.
