Since Bcl3 gene expression is significantly increased in ovarian clear-cell adenocarcinoma, endometrioid adenocarcinoma, ovarian mucinous adenocarcinoma, ovarian serous adenocarcinoma and ovarian serous surface papillary carcinoma [47], Bcl3 might serve as a potential novel biomarker in OC. The gene discussed is BCL3; the disease is ovarian clear cell adenocarcinoma.
