The differential expression of 7 DEGs in ovarian cancer, normal fallopian tube (FT), and ovary tissues was analyzed using the data from TCGA-GTEX database, and the results showed that only TIMELESS was overexpressed, and OBSL1, DNASE1, CSNK1E, and ZNF711 were downregulated in ovarian cancer compared with normal FT and ovary tissues (Fig. 4E). Here, DNASE1 is linked to ovarian carcinoma.
