Consistent with previous observations, overexpression of GLUD1 suppressed HBX-facilitated cell growth (Supplementary Figure S3A and B) and migration (Supplementary Figure S3C and D) in HBX-expressing HCC cells and the growth of HCC tumor xenografts induced by HBX in vivo (Supplementary Figure S3E–G). This evidence concerns the gene GLUD1 and hepatocellular carcinoma.
