A novel role of Kruppel-like factor 4 in Zhikong scallop Chlamys farreri during spermatogenesis.

ABSTRACT: Krüppel-like factor 4 (KLF4) is a kind of zinc finger transcription factor, which is involved in terminal differentiation of epithelial cells and reprogramming of somatic cells to induced pluripotent stem (iPS) cells in mammals. In the present study, we identified a full-length cDNA of Klf4 in Zhikong scallop Chamys farreri (Cf-Klf4) and found that Cf-Klf4 presented a sexual dimorphic expression characteristic in C. farreri gonads. Cf-Klf4 expression was significantly higher in testes than in ovaries from growing stage to mature stage detected by quantitative real-time PCR, and was located in male gametes, except for spermatozoa during spermatogenesis through in situ hybridization and immunohistochemistry, while no positive signal was visible in female gametes during oogenesis.
