From: Crosstalk between autophagy and microbiota in cancer progression
Different proteins or small molecules regulate autophagy pathways. Autophagy is a key regulator during tumorigenesis. It can not only promote cancer by providing nutrition for tumor cells but can also inhibit cancer progression by increasing apoptosis. Autophagy can be divided into four parts: initiation, elongation, maturation, and the fusion of autophagosomes and lysosomes. ATGs participate in each step and eventually promote or inhibit cancer
