In another work on ccRCC, it was found that the expression of circHIAT1 is downregulated by AR and through suppressing its host gene named HIAT1 at the transcriptional level via a regulatory axis involving of the circ_HIAT1 and miR‐195‐5p/29a‐3p/29c‐3p/CDC42.14 Here, CDC42 is linked to nonpapillary renal cell carcinoma.
