Additionally, we interrogated ovarian cancer datasets (http://www.rocplot.org/ovarian/index, accessed on 12 February 2022) to determine the differential expression (box plot; chemoresistance vs. chemosensitive) and test performance (receiver operating characteristic (ROC) analysis; chemoresistance prediction) of VPS18, VPS39 and VPS41. Here, VPS39 is linked to ovarian carcinoma.
