Zhang B et al. found that LncRNA TUG1 is the ceRNA of Mir-141-3p and inhibits its expression, thereby down-regulating downstream β -catenin expression, activating C-MYC, accelerating glutamine metabolism of ccRCC cells, and thus promoting ccRCC migration 85. The gene discussed is TUG1; the disease is nonpapillary renal cell carcinoma.
