Figure 5: Survivin protein stability is increased in the presence of autophagy inhibitors in serum-free media, but not in serum-containing media. Western blots and protein quantitation graphs showing survivin protein levels over time after addition of CHX (100 μM) to media. One representative western blot out of three repeat experiments was shown for each treatment and condition. The prominent band shown is survivin while the smaller bands are nonspecific, as determined via control experiments utilizing a neutralizing peptide for the survivin antibody. *Indicates the time at which survivin protein is half of the amount at 0 hours (half-life), .
