Furthermore, miR-20a has been shown to negatively regulate autophagy by targeting RB1CC1/FIP200 in breast cancer cells (Li S. et al., 2016) and inhibit autophagy induced by leucine deprivation via suppression of ULK1 expression in C2C12 myoblasts (Wu et al., 2012). Here, RB1CC1 is linked to breast cancer.
