CDKL1 and neoplasm: Amongst the host genes whose circRNAs harbor miRNA target sites, 4 were differentially expressed (both at the mRNA and at circRNA level) between the tumor grade subtypes: CDKL1, HP1BP3, MVB12B, and TMPO. The circRNAs from these 4 host genes harbor target sites for 11 different miRNAs: miR-7-5p, miR-30-5p, miR-31-5p, miR-96-5p/1271-5p, miR-139-5p, miR-181-5p, miR-182-5p, miR-433-3p, miR-489-3p, miR-493-5p, and miR-543.
