A pan-cancer analysis based on The Cancer Genome Atlas (TCGA) in Tumor Immune Estimation Resource 2.0 (TIMER2.0; http://timer.cistrome.org/; Li et al., 2020) has also shown that there is significant upregulation of RHOA mRNA expression across 12 of the 34 tumor types compared to their equivalent normal counterparts, with stomach adenocarcinoma (STAD) being one of them (Fig. S1A). Here, RHOA is linked to neoplasm.
