The TISIDB database showed that the mRNA levels of DHCR7 were significantly differentially expressed between the tumor stages I and III or IV in BLCA (spearman r = 0.13, p = 0.00854) (Figure 3A), KICH (spearman r = 0.253, p = 0.0408) (Figure 3B), KIRP (spearman r = 0.249, p = 4.75e‐05) (Figure 3C), LUAD (spearman r = 0.139, p = 0.00165) (Figure 3D), LUSC (spearman r = 0.114, p = 0.0113) (Figure 3E) and TGCT (spearman r = 0.353, p = 0.00123) (Figure 3F). Here, DHCR7 is linked to neoplasm.
