Abstract
Previous studies have shown that the activation of p38MAPK signaling plays a crucial role in regulating gonadal cell fate decisions in both mouse and human. Excessive activation of p38MAPK by radiation significantly causes testicular damage and negatively affects the male reproductive function. Therefore, fine-tuned regulation of p38MAPK signaling is critical in both physiological and pathological conditions. This review summarizes the impact of p38MAPK signaling on testicular germ cells and microenvironment under normal condition. The relationship between radiation, reactive oxygen species (ROS), and p38MAPK is summarized. In conclusion, radiation exposure triggers the overactivation of p38MAPK, which is regulated by ROS, resulting in testicular damage. Various p38MAPK-targeting agents are discussed, providing guidance for developing new strategies.
