ULK1 and breast cancer: Next, we used the inhibitors for AMPK (compound C) and ULK1 (SBI-0206965) to block AMPK-ULK1 pathway, and the results showed that both compound C and SBI-0206965 reversed Dox-induced autophagy in DR-BC cells, suggesting that Dox activated autophagy in a AMPK-ULK1 pathway dependent manner, which were supported by the previous work [21].
