In support to our prediction, we observed significant upregulation of PTBP1 expression in tumor samples compared to normal (p = 0.0467) (Fig. 2c) and it showed significant positive correlation with EGFR-A isoform (r = 0.7404, p < 0.0001) (Fig. 2d). The gene discussed is PTBP1; the disease is neoplasm.
