On the other hand, the analysis of benign or borderline ovarian tumors (n = 16) and clear cell ovarian cancers (n = 5) identified low NOTCH1/3 expressions and also presented low expressions of Notch-related lncRNAs and their related gene sets, compared to those in HGSC (n = 79) (Figure 4D–G). Here, NOTCH1 is linked to ovarian clear cell cancer.
