p53/HMGB1 Complexes Regulate Autophagy and Apoptosis

Abstract excerpt

The balance between apoptosis ("programmed cell death") and autophagy ("programmed cell survival") is important in tumor development and response to therapy. Here, we show that high mobility group box 1 (HMGB1) and p53 form a complex that regulates the balance between tumor cell death and survival. We show that knockout of p53 in HCT116 cells increases expression of cytosolic HMGB1 and induces autophagy....
