In particular, the expression of several well-known circRNAs was plotted in Supplementary Fig. 4b, whereas cancer-related circRNAs like hsa-CDYL_0005, has-BARD1_0006, hsa-HIPK3_0001, and hsa-FAM120A_0006 can be successfully detected in both normal and carcinoma cells53–56. This evidence concerns the gene FAM120A and cancer.
