Excerpt
Proteomic technologies verified AGR-2 as a protein family overexpressed in human cancers, including breast, prostate and oesophagus cancers, with the ability to inhibit the tumour suppressor protein p53 [
1]. The
AGR-2 gene is a hormone responsive gene with an unexpected induction by the anticancer drug tamoxifen highlighting the proto-oncogenic role of this protein. The
hAGR-2 gene was first described in the MCF-7 breast carcinoma cell line, and was found to be coexpressed with the estrogen receptor (ER), in ER-positive cell lines [
2,
3]. Moreover, it was recently revealed that AGR-2 is secreted from androgen-inducible cell lines in prostate cancer cell lines [
