Octylphenol and nonylphenol affect decidualization of human endometrial stromal cells

초록

This study investigated the effect of octylphenol (OP) and nonylphenol (NP) on decidualization of endometrial stromal cells. Telomerase-immortalized human endometrial stromal cells were cultured for 12 days and decidualization was induced in vitro. The cells were exposed to OP (5 or 10 mu M) or NP (5 mu M) during in vitro decidualization. The expression levels of decidualization markers were analyzed using qRT-PCR. The amount of prolactin (PRL) and insulin-like growth factor binding protein 1 (IGFBP1) was measured in medium using ELISA. The expression levels of PRL and IGFBPI were significantly decreased by treatment with OP or NP. The amounts of PRL and IGFBP1 were also significantly decreased by treatment with OP or NP. The patterns of PRL and IGFBP1 secretion into medium were consistent with their expression patterns. The findings indicate that OP or NP may disrupt the decidualization of endometrial stromal cells and eventually affect the reproductive health of women.
