To observe the effect of Cai’s Neiyi Prescription (CNYP) on the apoptosis and inflammation in endometrial stromal cells with endometriosis (EM) both in vivo and in vitro, EM model rats and endometrial stromal cells were treated with CNYP and the level of USP10, p-ERK1/2, ERK1/2, and apoptosis-related protein as well as the levels of proinflammatory factors were measured by Western blotting and ELISA, respectively. Rats with surgically induced EM showed increased USP10 expression and ERK/2 activation. Intragastric administration of CNYP granule significantly inhibited EM-induced ERK1/2 activation and expression of USP10 and Bcl-2, but increased the expression of Bax and Caspase-7 in EM-induced rats. CNYP granule administration also inhibited EM-induced inflammation in rats. Moreover, the ectopic endometrial stromal cells isolated from EM patients demonstrated decreased ERK1/2 activation and expression of USP10 and Bcl-2 and increased expression of Bax and Caspase-7 after cultured in DMEM containing CNYP-medicated rat serum, which were reversed by USP10 overexpression and were enhanced by USP10 siRNA. USP10 overexpression also inhibited while USP10 siRNA enhanced the CNYP-induced inhibition of inflammation in ectopic endometrial stromal cells. Taken together, our results suggest that CNYP granule promotes apoptosis and inhibits inflammation in endometrial stromal cells with EM through inhibiting USP10.
