Klotho regulated cell viability, apoptosis, invasion and senescence in hypoxic human trophoblasts by regulating the Nrf2/ARE signal pathway. A, B The cell viability of human trophoblasts was determined by using the MTT assay. C Cell apoptosis in human trophoblasts was determined by using the apoptosis detection kit. D Transwell assay was performed to examine cell invasion abilities of human trophoblasts. E The cellular senescence-associated proteins (p16 and p21) were examined by performing Western Blot analysis. Each experiment was repeated at least for three times, and *P < 0.05 was considered as statistical significance. Each experiment was repeated at least for three times
