BUB1 and cancer: This module contained a number of genes previously linked to prostate or other types of cancers including RAD51, AURKA, CENPE, EZH2, TOP2A, BUB1, TPX2, CDK1, and CCNB1. Because of the overlapping transcriptomes of full‐length AR and AR‐V7, we examined whether full‐length AR also regulated genes in the green module.
