RAB3A and hepatocellular carcinoma: To investigate the mechanisms how Rab3A and its O-GlcNAcylation regulate HCC progression, we analyzed the co-expression genes with RAB3A and/or OGT in TCGA-LIHC dataset, and determined 147 genes moderately correlated with RAB3A (Pearson |R| > 0.3, p < 0.001) (Fig. 5a and Additional file 8: Table S3.1).
