Up-regulation of RALA expression was significantly positively correlated with M1 macrophages in bladder urothelial cancer (BLCA), BRCA, head and neck squamous cell cancer (HNSC), LGG, HCC, LUAD, LUSC, MESO, PAAD, stomach adenocarcinoma (STAD), THCA and UVM (Figure 4A). Here, RALA is linked to bladder transitional cell carcinoma.
