On the other hand, with the increase in the MP risk factor, expression levels of ATF2A (activating transcription factor 2A), ATG3, ATG4, ATG4B, ATG4C, ATG5, ATG9A, ATG9B, ATG12, ATG13, and ATG101 increased, suggesting their role in worsening breast cancer prognosis. The gene discussed is ATG5; the disease is breast cancer.
