Unraveling tumor suppressor networks with in vivo RNAi

Abstract

BMI1 is a known oncogenic transcriptional repressor in glioblastoma stem-like cells, but its downstream mediators are poorly understood. Recently, in Cancer Cell, Gargiulo et al. (2013) designed a rational in vivo RNAi screen based on BMI1 ChIP-seq from neural progenitors and identified functional tumor suppressor targets, including Atf3 and Cbx7.
