MAP1LC3A and gallbladder cancer: Furthermore, immunohistochemical staining of PGK1, LC3, p62, ATG5 and ATG12 showed that PGK1, ATG5 and ATG12 were dramatically downregulated in Lv-shRNA-GBCDRlnc1 group and confirmed that knockdown of GBCDRlnc1 inhibited the autophagic activity of gallbladder cancer cells in vivo, which is consistent with the aforementioned results in vitro (Fig. 8c).
