Core Tip

Core Tip: This study demonstrated that mitogen-activated protein kinase kinase 7 regulates the proliferation and apoptosis of human spermatogonial stem cells by mediating the phosphorylation of c-Jun N-terminal kinases in vitro. In addition, we found that mitogen-activated protein kinase kinase 7 was significantly downregulated in patients with reproductive disorders, suggesting that mitogen-activated protein kinase kinase 7 may be associated with human spermatogenesis.
