RB1 and hepatocellular carcinoma: Transcription analyses of HCC RNA-sequencing data (The Cancer Genome Atlas, PanCancer Atlas) by cBioPortal (http://www.cbioportal.org) showed that PGM1 mRNA expression had no or low correlation with the mRNA expressions of CTNNB1 (r = 0.255), MYC (r = 0.009), IGF2 (r = −0.276), TGFA (r = −0.288), TP53 (r = −0.374), or RB1 (r = −0.11) genes (S1D Fig).
