The “Pathological Stage Plot” module from GEPIA2 was used to analyze the relationship between STK38 expression and the pathological staging in different tumors, which demonstrated that there were significant stage-specific expressional changes in some cancers including adrenocortical carcinoma (ACC), LIHC, ovarian serous cystadenocarcinoma (OV), pancreatic adenocarcinoma (PAAD), thyroid carcinoma (THCA), UCEC, SKCM (Figure 1B, all p < 0.05), while in other cancers, we found no clear relationship. This evidence concerns the gene STK38 and pancreatic adenocarcinoma.
