THRB and clear cell renal carcinoma: Analysis of expression in tissue samples revealed that upregulation of miR-155 and miR-425 in clear cell renal cell carcinoma is accompanied by downregulation of THRB. Insufficient specificity of the commercially offered anti-TRβ antibodies and extremely low expression levels of the TRβ protein did not allow for showing the miR-mediated effect on the TRβ protein level.
