Genetic response to DNA damage: proapoptotic targets of RhoB include modules for p53 response and susceptibility to Alzheimer's disease.

Abstract excerpt

Knockout mouse studies indicate that the small GTPase RhoB is critical for apoptosis triggered by genotoxic stress in transformed mouse cells. However, the mechanisms used by RhoB to sensitize cells to cell death are obscure. To gain insight into this question, we compared the genetic response of cells with different rhoB genotypes to the DNA damaging anticancer drug doxorubicin (DOX). The microarray...
