HLA-G and renal cell carcinoma: To assess whether an inverse correlation between the expression levels of HLA-G and the two novel putative HLA-G-regulatory miRs detected in vitro also exists in situ 36 selected HLA-G+ and 36 HLA-G− RCC lesions were monitored for miR-548q and miR-628-5p expression as recently described for the miRs of the miR-148 family and the miR-133a [8].
