ABSTRACT
Benign prostatic hyperplasia (BPH) is a non-malignant disease of the prostate characterized by uncontrolled proliferation of the prostate gland. Inflammation and oxidative stress have been reported to play a role in the development of BPH. Kolaviron, a bioflavonoid complex of Garcinia kola seed, has been shown to possess anti-inflammatory effect. In this study, we investigated the effect of Kolaviron on testosterone propionate (TP)-induced BPH in rats. Fifty male rats were assigned in 5 groups. Groups 1 and 2 were orally exposed to corn oil (2 ml/kg) and Kolaviron (200 mg/kg/day, p.o) for 28 days. Group 3 rats received TP (3 mg/kg/day, s.c) for 14 days while Groups 4 and 6 were treated with Kolaviron (200 mg/kg/day, p.o) and Finasteride (5 mg/kg/day, p.o), respectively, for 14 days prior to TP (3 mg/kg, s.c) co-exposure for the remaining 14 days. Administration of Kolaviron to TP-treated rats reverted histological alteration and significantly decreased prostate weight, prostate index, 5α-reductase, dihydrotestosterone, androgen receptor expression, tumor necrosis factor α, interleukin-1ß, cyclooxygenase-2, prostaglandin E2, 5-lipoxygenase leukotriene B4, inducible nitric oxide synthase and nitric oxide concentration. In addition, Kolaviron alleviated TP-induced oxidative stress and reduced the expression of Ki-67, VEGF, and FGF to almost control levels. Furthermore, Kolaviron promoted apoptosis in TP-treated rats through downregulation of BCL-2 and upregulation of P53 and Caspase 3 expressions. Overall, Kolaviron prevented BPH via regulation of androgen/androgen receptor signaling, anti-oxidative and anti-inflammatory mechanisms.
