To find the upstream of a selected RBP, starBase v2.0 was utilized to find RBP-LncRNA targets, with the consideration of the threshold of strict stringency (≥ 5) and pan-Cancer ≥ 10 cancer types in starBase v2.0, hub LncRNAs (|log2 FC|≥ 1, FDR < 0.05 and P value < 0.05) in TCGA ccRCC, LncRNAs positively correlated with AXL (correlation coefficient ≥ 0.3 and P value < 0.001) in TCGA ccRCC. Here, AXL is linked to nonpapillary renal cell carcinoma.
