STAT3 and cancer: Because ROS‐mediated activation of STAT3 signaling is involved in stress‐induced cellular senescence (Liu et al., 2017), and because ROS/STAT3 signaling pathway also regulates autophagy of cancer cells (Yoon et al., 2010), we reason that LMCD1 may function as an important converging point linking oxidative stress, testicular phagocytosis, and SC senescence.
