MAP1LC3A and gastric cancer: In addition, we expressed a tandem monomeric RFP-GFP-tagged LC3 in GC cells and found that CPX-treated cells contained abundant GFP-/RFP+-LC3 and GFP+/RFP+-LC3 compared to the control treatment, implying the formation of autophagosomes and autolysosomes in CPX-treated GC cells (Fig. 2C, D).
