Currently, employing the datasets from TCGA and Clinical Proteomic Tumor Analysis Consortium (CPTAC, http://ualcan.path.uab.edu/analysis.html), we demonstrated that PTBP1 mRNA and protein levels were markedly elevated in NSCLC tissues compared to adjacent controls (Fig. 7A, B), which was negatively associated with circEPB41L2 levels (Fig. 7C). This evidence concerns the gene PTBP1 and neoplasm.
