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-1β, 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.

Front Pharmacol 2021; 12:667524. [PMID: 33995096 PMCID: PMC8116945 DOI: 10.3389/fphar.2021.667524] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Accepted: 04/12/2021] [Indexed: 12/11/2022] Open
Abstract
Random-pattern skin flap is widely used in tissue reconstruction. However, necrosis occurring in the distal part of the flap limits its clinical application to some extent. Activation of autophagy has been considered as an effective approach to enhance the survival of skin flaps. Pseudoginsenoside F11 (PF11), an ocotillol-type saponin, is an important component of Panax quinquefolium which has been shown to confer protection against cerebral ischemia and alleviate oxidative stress. However, it is currently unknown whether PF11 induces autophagy to improve the survival of skin flaps. In this study, we investigated the effects of PF11 on blood flow and tissue edema. The results of histological examination and western blotting showed that PF11 enhanced angiogenesis, alleviated apoptosis and oxidative stress, thereby improving the survival of the flap. Further experiments showed that PF11 promoted nuclear translocation of TFEB and by regulating the phosphorylation of AMPK. In summary, this study demonstrates that PF11 activates autophagy through the AMPK-TFEB signal pathway in skin flaps and it could be a promising strategy for enhancing flap viability.

Cyclopamine functions as a suppressor of benign prostatic hyperplasia by inhibiting epithelial and stromal cell proliferation via suppression of the Hedgehog signaling pathway. Int J Mol Med 2020; 46:311-319. [PMID: 32319534 PMCID: PMC7255449 DOI: 10.3892/ijmm.2020.4569] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2018] [Accepted: 03/12/2019] [Indexed: 12/17/2022] Open
Abstract
Stromal-epithelial interaction serves a pivotal role in normal prostate growth, as well as the onset of benign prostatic hyperplasia (BPH). The present study aimed to explore the role of cyclopamine in the proliferation and apoptosis of epithelial and stromal cells in rats with BPH by blocking the Hedgehog signaling pathway. Cyclopamine (an inhibitor of the Hedgehog signaling pathway) was administered in a rat model of BPH, and the expression of Ki67 (proliferation factor) was determined by immunohistochemistry. In addition, epithelial and stromal cells were separated and cultured in order to investigate the role of cyclopamine in the progression of BPH. The expression of Hedgehog signaling pathway- and apoptosis-related genes, including basic fibroblastic growth factor (b-FGF) and transforming growth factor β (TGF-β), was evaluated using reverse transcription-quantitative polymerase chain reaction and western blot analysis. Cell proliferation, cell cycle and apoptosis were analyzed using an MTT assay and flow cytometry. We identified upregulated Ki67 expression and activated Hedgehog signaling pathway in rats with BPH. Cyclopamine inhibited the activation of the Hedgehog signaling pathway. In response to cyclopamine treatment, epithelial and stromal cell proliferation was inhibited; this was concomitant with decreased Ki67, TGF-β, and b-FGF expression. On the other hand, epithelial cell apoptosis was enhanced, which was associated with increased Bax and reduced Bcl-2 expression. Based on these findings, we proposed that cyclopamine may serve as a potential therapeutic agent in the treatment of BPH. Cyclopamine could inhibit epithelial and stromal cell proliferation, and induce epithelial cell apoptosis by suppressing the Hedgehog signaling pathway.

Abstract
Benign prostatic hyperplasia (BPH) is common among elderly men, of which inflammation, oxidative stress, proliferative, and apoptotic changes play important roles. Xialiqi (XLQ) capsule, a traditional Chinese herbal formula, is used as a potential drug in treating BPH. This study aims to evaluate the therapeutic effect of XLQ capsule on testosterone propionate- (TP-) induced BPH in rats. Fifty male Sprague-Dawley rats were randomly divided into 5 groups: sham control, BPH model, high and low dose of XLQ, and finasteride as a positive control group. All groups were treated with appropriate drugs/normal saline for 28 consecutive days. Prostate weights were recorded; histopathological changes and content of IL-8, TNF-α, DHT, SOD, MDA, caspase-3, and PCNA of the prostate were determined. Animals with BPH demonstrated significantly increased prostate weights and prostate index, higher levels of IL-8, TNF-α, DHT, MDA, and PCNA, but lower activity of SOD and reduced expression of caspase-3. After treatment with XLQ, significant reductions of prostate weights, prostate index, IL-8, TNF-α, DHT, MDA, and PCNA, increased activity of SOD, and higher level of caspase-3 were shown. The present study indicates that XLQ can effectively prevent the development of TP-induced BPH model through mechanisms of anti-inflammation, antioxidation, antiproliferation, and proapoptosis.

Abstract
Exercise has beneficial effect on cancer apoptosis and benign prostatic hyperplasia (BPH). The BH3 interacting domain death agonist (BID) gene expression is associated with apoptosis or cell proliferation. In this study, we investigated the association between BID single nucleotide polymorphisms (SNPs) and the development, prostate volume, and international prostate symptom score (IPSS) of BPH. In 222 BPH males and 214 controls, two SNPs in BID [rs8190315 (Ser56Gly), and rs2072392 (Asp106Asp)] were genotyped and analyzed using multiple logistic regression models. In the result, the genotype and allele frequencies of rs8190315 and rs2072392 were not associated with BPH development or IPSS, however, the allele frequencies [odd ratio (OR)= 1.90, 95% confidence interval (CI)= 1.07–3.41, P= 0.03] and genotype frequencies (in dominant model, OR= 1.94, 95% CI= 1.01–3.74, P= 0.42) of rs8190315, and the genotype frequencies of rs2072392 (in dominant model, OR= 1.94, 95% CI= 1.01–3.74, P= 0.42) were associated with increased prostate volume. We propose that rs8190315 and rs2072392 of BID may contribute to the disease severity of BPH.

Abstract
Purpose Benign prostatic hyperplasia (BPH) is the most common prostate problem in older men. The present study aimed to investigate the inhibitory effect of Panax ginseng C.A. Meyer (P. ginseng) on a rat model of testosterone-induced BPH. Methods The rats were divided into 3 groups (each group, n=10): control, testosterone-induced BPH (20 mg/kg, subcutaneous injection), and P. ginseng (200 mg/kg, orally) groups. After 4 weeks, all animals were sacrificed to examine the blood biochemical profiles, prostate volume, weight, histopathological changes, alpha-1D adrenergic receptor (Adra1d) mRNA expression, and epidermal growth factor receptor (EGFR) and B-cell CLL/lymphoma 2 (BCL2) protein expression. Results The group treated with P. ginseng showed significantly lesser prostate size and weight than the testosterone-induced BPH group. In addition, P. ginseng decreased the mRNA expression of Adra1d as well as the expression of EGFR and BCL2 in prostate tissue. Conclusions These results suggest that P. ginseng may inhibit the alpha-1-adrenergic receptor to suppress the development of BPH.
