Differences in the role of Gper1 in colorectal cancer progression depending on sex.

ABSTRACT: To evaluate the role of 17β-oestradiol (E2) in the sex-dependent progression of colorectal cancer (CRC), the present study focused on E2 signalling mediated via the nuclear receptors [oestrogen receptor (ESR)1 and ESR2] and the membrane G protein-coupled oestrogen receptor 1 (Gper1) in males and females diagnosed with CRC. This study also investigated Gper1 signalling in the CRC cell lines DLD1 and LoVo, which differ in the p53 pathway. In cancer tissue, Gper1 becomes by far the most abundant E2 receptor due to an increase in Gper1 and a decrease in ESR2 expression. These changes are more prominent in males than in females. More pronounced differences in Gper1 expression between cancer and adjacent tissues were observed in males in lower stages compared with those in higher stages o
