LAMB1 and intrahepatic cholangiocarcinoma: Most importantly, KEGG and GSEA analysis showed that LAMB1 played a pivotal role in pro-metastatic processes, including focal adhesion, ECM-receptor interaction, and cellular junction in LIHC, CHOL, and COAD, highlighting that LAMB1 might also be a potential treating target for cHCC-ICC (Additional file 1: Fig. S2).
