Also, X. Wang et al. research presented a remarkable surge in PD-L1 expression on gastric cancer cell lines with the use of autophagy inhibitors chloroquine (CQ), 3-methyladenine, and bafilomycin A1 (Baf), which influenced the p62/SQSTM1-NF-κB pathway [157]. Here, SQSTM1 is linked to gastric cancer.
