Аннотация
OBJECTIVE: To study the effect of human chorionic gonadotropin (hCG) on olfactomedin-1 (Olfm1) expression and spheroid attachment in human fallopian tube epithelial cells in vitro.
DESIGN: Experimental study.
SETTING: Reproductive biology laboratory.
PATIENT(S): Healthy nonpregnant women.
INTERVENTION(S): No patient interventions.
MAIN OUTCOME MEASURE(S): Luteinizing hormone/chorionic gonadotropin receptor (LHCGR) and Olfm1 expression in fallopian tube epithelium cell line (OE-E6/E7 cells). OE-E6/E7 cells treated with hCG, U0126 extracellular signal-regulated kinase (ERK) inhibitor, or XAV939 Wnt/β-catenin inhibitor were analyzed by Western blotting, real-time polymerase chain reaction, and in vitro spheroid attachment assay.
RESULT(S): Human chorionic gonadotropin increased spheroid attachment on OE-E6/E7 cells through down-regulation of Olfm1 and activation of Wnt and mitogen-activated protein kinase (MAPK) signaling pathways. U0126 down-regulated both MAPK and Wnt/β-catenin signaling pathways and up-regulated Olfm1 expression. XAV939 down-regulated only the Wnt/β-catenin signaling pathway but up-regulated Olfm1 expression.
CONCLUSION(S): Human chorionic gonadotropin activated both ERK and Wnt/β-catenin signaling pathways and enhanced spheroid attachment on fallopian tube epithelial cells through down-regulation of Olfm1 expression.
