The treatment of human androgen-sensitive LNCaP and hormone refractory PC-3 prostate cancer cells with UA (55 μM for 24 and 48 h) reduced viability (MTT assay) and induced apoptosis (Annexin assay) and these effects were associated with a downregulation of the anti-apoptotic protein B-cell lymphoma 2 (Bcl-2) [38] (Table 1). Here, BCL2 is linked to prostate cancer.
