This study aimed to elucidate the roles of cilia- and flagella-associated protein 61 (CFAP61) in male infertility and its underlying mechanisms. CFAP61 expression levels in the testicular tissues of male patients with infertility were determined using quantitative real-time polymerase chain reaction, immunohistochemical assay, and western blotting. Moreover, the specific roles of CFAP61 in male infertility were evaluated using cell counting kit-8, 5-ethynyl-2'-deoxyuridine, flow cytometry, and enzyme-linked immunosorbent assays. Here, CFAP61 was expressed at low levels in the testicular tissues of male patients with infertility. Functionally, CFAP61 knockdown reduced the Leydig cell viability and testosterone secretion and enhanced apoptosis. A mechanistic study further revealed that silencing CFAP61 promoted the expression levels of mitogen-activated protein kinase (MAPK)/cyclooxygenase-2 (COX-2) signaling pathway-related proteins (p-extracellular signal-regulated kinase (p-ERK), p–c-Jun N-terminal kinase (p-JNK), p-P38, and COX-2). In conclusion, CFAP61 knockdown facilitated male infertility by suppressing Leydig cell viability and testosterone secretion and enhanced cell apoptosis by activating the MAPK/COX-2 pathway. Our data suggest CFAP61 as a potential therapeutic target for male infertility. [ABSTRACT FROM AUTHOR] |
