The Expression and Function of NUMB in Endometrial Cancer and the Interaction with HDM2 and P53

Abstract

Based on present data, we think NUMB acts as an anti-oncogene role and could regulate p53 level and function in endometrial cancer like in other cancers, meanwhile, the function of NUMB depend on P53. On the other hand, the location of NUMB could be regulated mainly by HDM2. So far we are not able to explain why endometrial cancer patients had high NUMB expression level since NUMB was regarded as a tumor suppressor, which is worthy studying further to explore underlying mechanism.
