NEDD4L and nonpapillary renal cell carcinoma: In our screening (Tables 2  and 3), although miR-23a was not identified as one of the putative miRNAs regulated by KSRP in ccRCC cells, it is still possible that miR-23a is involved in KSRP-mediated NEDD4L mRNA decay in ccRCC, but this issue needs to be further determined.
