OVOL1 expression is elevated in pancreatic cancer and has diagnostic potential. (A, B) The expression of OVOL1 in pancreatic cancer and normal tissues was investigated in the TCGA cohort (A) and GSE71729 cohort (B). (C) Immunohistochemistry analysis of OVOL1 in pancreatic cancer and adjacent normal tissues. (D, E) The diagnostic value of OVOL1 expression in the TCGA pancreatic cancer cohort was determined by ROC curve analysis (D), and the PPV, NPV, SEN, and SPE were calculated (E). PPV, positive predictive value; NPV, negative predictive value; SEN, sensitivity; and SPE, specificity. **p < 0.01 and ***p < 0.001.
