Glucuronidation is an enzymatic process that terminally inactivates steroid hormones, including estrogens and androgens, thereby influencing carcinogenesis in hormone-dependent cancers. While estrogens drive breast carcinogenesis via the estrogen receptor alpha (ERα), androgens play a critical role as prohormones for estrogen biosynthesis and ligands for the androgen receptor (AR). Herein, the expression and regulation of two androgen inactivating UDP-glucuronosyltransfer...

Estrogen receptor α (ERα) is a key transcriptional regulator in the majority of breast cancers. ERα-positive patients are frequently treated with tamoxifen, but resistance is common. Through ChIP-seq analyses, we presviously identified direct target genes of ERα acting in complex with SRC1, SRC2 or SRC3 (Zwart et al., 2011 EMBO J). Only the 111 genes there were under direct control of ERα in conjunction with SRC3 (but not the other two p160s) predicted...
