This increase of hsa-miR-144-5p and hsa-miR-186 excretion in ccRCC and the decrease in the production of hsa-miR-186-3p by HKC-8 was always followed by an increase of GLUT-1 mRNA levels, showing the importance of these miRNAs for the regulation of GLUT-1’s mRNA levels. This evidence concerns the gene SLC2A1 and nonpapillary renal cell carcinoma.
