SNCG is overexpressed in EOC tissue and correlated with poor prognosis in patients with HGSOC. a IHC staining showed SNCG expression in the normal ovary, fallopian tube tissues, benign tumor, and borderline tumor (original magnification, × 200). b Representative images of IHC staining of SNCG expression in different pathological types of EOC tissues (original magnification, upper× 200, lower×400). c Kaplan-Meier analysis was performed for EOC patients to analyze the association between SNCG expression and survival outcome (OS and PFS). d In the HGSOC cohort, Kaplan-Meier analysis indicated the correlation of SNCG overexpression with OS (upper) and PFS (lower). By multivariate Cox regression analysis (Forest plot), results showed that SNCG overexpression was an independent prognostic factor
