Additionally, ITGB2 was found to be positively expressed (27.27%) in the cytoplasm in serous ovarian cancer cells and tissues (Figure 5a–d) but was almost negative (5.93%) in the normal ovarian epithelial cells and non-tumor tissues, with a significant difference (p < 0.0001) (Figure 5e). The gene discussed is ITGB2; the disease is ovarian serous adenocarcinoma.
