As shown in Figure 4A, high expression of GJB2, S100A2, SPOCK2, TGM1or EPS8 indicated a poor OS of patients with ovarian cancer, whereas ovarian cancer patients with higher expression of ADAMDEC1, CHEK1, EGFL6, FAM181A, FOXA2, LYPD1, PART1 or XPR1 possessed better OS. This evidence concerns the gene SPOCK2 and ovarian cancer.
