MCM7 and nonpapillary renal cell carcinoma: The individual roles of miR-25-3p, miR-93-5p, and miR-106b-5p in ccRCC have been previously characterized [20,24,30,31]; the concomitant action of the three microRNAs acting as a single functional factor, as well as the combined role of MCM7 and the miR-106b-25 cluster as a whole, has not been described.
