Background

The expression of the Noxa gene, a BH3 only member of the Bcl2 family, involves direct activation of its promoter by p53. Increased expression of Noxa protein occurs in normal thymocytes but not in p53 deficient thymocytes. Co-immunoprecipitation data suggests that Noxa protein may interact with proteins belonging to the Bcl2 family, such as, BclXL and Mcl1. Blocking endogenous Noxa induction results in the suppression of apoptosis. Treatment of cells with Noxa antisense oligonucleotides blocks radiation induced apoptosis, suggesting that Noxa may mediate p53 dependent apoptosis.
