Compared to normal tissues, ZBTB20-AS4, CIRBP-AS1, GDNF-AS1, and LINC00265 were differentially expressed in a variety of tumors, including BRCA, COAD, KIRC, KIRP, LUAD, LUSC, and UCEC, suggesting that these m5C-related lncRNAs may be conserved in the tumor progression (Figure 2E). Here, CIRBP is linked to neoplasm.
