PTBP1 and non-small cell lung carcinoma: 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).
