ABSTRACT
Male infertility is closely associated with spermatogenesis disorders triggered by aberrant gene expression or abnormal signaling pathways in the testis. The mammalian target of rapamycin (mTOR) is a central regulator of cell metabolism, playing an important role in regulating cell proliferation, differentiation, translation, actin polymerization, cycle progression, energy metabolism, autophagy, and other cellular activities. PI3K-Akt and LKB1-AMPK, the two well-defined classic signal transduction pathways, regulate the expressions of mTOR and its downstream p70S6K/4EBP1 through different molecular pathways. Recent studies show that mTOR-p70S6K/4EBP1 signaling participates in the regulation of the proliferation and differentiation of testicular cells and spermatogenesis. This review focuses on the role of PI3K-Akt/LKB1- AMPK-mTOR signaling cascades in testis development and spermatogenesis, providing some new perspectives for the studies of the molecular mechanism underlying male sterility.
