Other studies indicated that HSPA6 may have an inhibitory effect on bladder cancer (Shin et al., 2017), lung cancer (Wang et al., 2020a), and triple-negative breast cancer (Hahm et al., 2021; Shen et al., 2021), while may be relevant to the early recurrence of human hepatocellular carcinoma (Yang et al., 2015). This evidence concerns the gene HSPA6 and urinary bladder cancer.
