ZFP57 and ovarian carcinoma: To further verify the above database analysis results, we used IHC to detect the expression of ZFP57 in 51 ovarian cyst and 151 various ovarian cancer subtypes clinical samples (123 serous ovarian cancer samples, 10 mucinous ovarian cancer samples, 11 endometrioid ovarian cancer samples and 7 clear cell ovarian cancer samples) and found that the ZFP57 expression in various types of OC was significantly increased compared to that in cysts (Table 1, Figure 1I).
