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. Here, ATG9A is linked to breast carcinoma.
