Previously, we identified LZTFL1 as a target of miR-106b-5p that promotes RCC aggressiveness and found that lower LZTFL1 expression was associated with shorter overall survival time (OS) of ccRCC patients through analysis of LZTFL1-mRNA in The Cancer Genome Atlas (TCGA) pan-cancer database [16]. This evidence concerns the gene LZTFL1 and nonpapillary renal cell carcinoma.
