Growing evidence has illustrated that Wnt/β-catenin pathway is hyperactivated in ovarian cancer, exerting essential functions in ovarian cancer stemness, drug resistance, metastasis, etc. For example, β-catenin was shown to play an important role in maintaining ovarian cancer stem cell phenotype through regulation of ALDH1A1 (20). The gene discussed is ALDH1A1; the disease is ovarian carcinoma.
