As indicated, in Figure 3A, five snoRNAs (SNORA81, SNORA56, SNORD72, SNORA6 and SNORA19) were mostly uniformly overexpressed in HGSC when compared with SBT and displayed similar or better association with high-grade ovarian cancer than the known mRNA markers VEGF-A and WFDC2. Here, WFDC2 is linked to ovarian cancer.
