Herein, it was demonstrated by Western blot that nucleolin was overexpressed in the cytoplasm and cell membrane (Figure 1B) of cell lines derived from different sub-types of patient-derived ovarian cancer as endometrioid ovarian carcinoma (TOV-112D) and high-grade serous ovarian carcinoma (OVCAR-3 and SKOV-3) [43], similar (excepting TOV-112D, p < 0.05) to the nucleolin positive control MDA-MB-435S cells. This evidence concerns the gene NUCLEOLIN and ovarian endometrioid carcinoma.
