Additionally, our study identified a number of novel markers, such as CASP14, CLEC2B, CADM3, NRBP2, SPC25, ESCO2, and GTSE1, which are upregulated in a cluster‐specific manner (Figure S2K) and critical for ovarian cancer cell proliferation and migration (Figure 3A, B). This evidence concerns the gene GTSE1 and ovarian cancer.
