Next, we stratified samples into 4 groups based on the combination of the HELQ and XAB2 expressions in ascites tumor cells: a high-expression HELQ/high-expression XAB2 group, a high-expression HELQ/low-expression XAB2 group, a low-expression HELQ/high-expression XAB2 group, and a low-expression HELQ/low-expression XAB2 group. Here, HELQ is linked to neoplasm.
