Chloroquine (CQ), an effective inhibitor of autophagosome and lysosome fusion, blocks autophagy in later stages.[44] Notably, when compared to Cd treatment alone, the addition of both CQ and 6 μm Cd did not affect MAP1LC3B‐II levels, suggesting that Cd impedes the clearance of autophagosomes in BC cells (Figure 1P,Q). Here, MAP1LC3B is linked to breast cancer.
