Abstract
One of the most common urological diseases is benign prostatic hyperplasia (BPH), with a high prevalence in the middle-aged and elderly male population. Patient's mental and physical health is affected significantly by this condition, causing them considerable discomfort. During the development of BPH, a synergistic effect occurs in response to inflammation, oxidative stress, and apoptosis induced by the activation of macrophages. The nuclear factor erythroid2-related factor 2 (Nrf2) signaling pathway can mediate macrophage activation and inhibit prostate hyperplasia by suppressing pro-inflammatory factors, anti-oxidative stress disorder, and initiating apoptosis. The purpose of this study was to review the mechanism of action of Nrf2 signaling pathway-mediated macrophage activation on the immune microenvironment of BPH and to summarize the Chinese medicine based on Nrf2 to provide an overview of BPH treatment options.

Quassinoids from Eurycoma longifolia Jack roots and their potential inhibitory activity against human benign prostatic hyperplasia cells (BPH-1) and testosterone-induced BPH rat model. Fitoterapia 2023; 166:105468. [PMID: 36931528 DOI: 10.1016/j.fitote.2023.105468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 03/01/2023] [Accepted: 03/03/2023] [Indexed: 03/18/2023]
Abstract
Benign prostate hyperplasia (BPH) is an enlargement of the prostate gland, because of hormonal changes in aging males which contribute significantly to excessive proliferation over apoptosis of prostatic cells. The anti-proliferative and induced apoptotic activities of Eurycoma longifolia quassinoids on cancer cell lines could be promising therapeutic targets on BPH. Hitherto, no report of the quassinoids against BPH problem was available. In this study, a systematic phytochemical fractionation of the root extract, TAF2 was performed, which led to the discovery of nine previously described C20 quassinoids (1-9). Two undescribed C20 (10 and 12) and one undescribed (11) C19 quassinoids were identified by detailed NMR and HR-ESI-MS data analysis. Their absolute configurations were assigned by ECD spectral analysis. The quassinoids (1-12) were tested for inhibitory activity against the proliferation of human BPH-1 and human skin Hs27 fibroblast cells cultured in vitro. 1, 2 and 3 at 10 μM significantly reduced BPH-1 cell viability and were cytotoxic to Hs27 fibroblast cells. 2 was selected for further study of anti-BPH activity against testosterone induced BPH rats. At 5 mg/kg, 2 reduced the rat prostatic weight and prostatic index, consistent with the decrease in papillary acini number and epithelial thickness of the prostate tissues. These quassinoids may be potential anti-BPH compounds that require further studies.

Origanum majorana L. Extract Attenuated Benign Prostatic Hyperplasia in Rat Model: Effect on Oxidative Stress, Apoptosis, and Proliferation. Antioxidants (Basel) 2022; 11:antiox11061149. [PMID: 35740046 PMCID: PMC9219805 DOI: 10.3390/antiox11061149] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 06/01/2022] [Accepted: 06/08/2022] [Indexed: 11/16/2022] Open
Abstract
Benign prostatic hyperplasia (BPH) is a widespread androgenic illness influencing elderly men. It is distinguished by prostatic epithelial and stromal muscle cell proliferation. Inflammation, oxidative stress, and apoptosis have all been interrelated to the development of BPH. Marjoram (Origanum majorana L.) is a herb with reported antiproliferative, proapoptotic, and antioxidative properties, which have not yet been studied in relation to BPH. Consequently, in this work, an ethanolic extract of O. majorana was prepared in two doses (250 and 500 mg/kg/day) to be injected into castrated rats after induction of a testosterone-BPH model. Testosterone propionate (TP) was subcutaneously injected (0.5 mg/kg/day) for one week after castration to induce BPH. Forty adult Wistar male rats were randomly allocated into five groups: control, BPH model, high and low O. majorana doses (250, 500 mg/kg/day), and finasteride (FN) (0.8 mg/kg/day) as a positive control. Treatment was continued with drugs/normal saline for 28 days. Rat’s body and prostate were weighed, prostate index (PI) and % of prostate growth inhibition were calculated, serum dihydrotestosterone (DHT), prostatic content of superoxide dismutase (SOD), catalase (CAT), total antioxidant capacity (TAC), and malondialdehyde (MDA), DN damage, histopathological changes, immune expression of proliferating cell nuclear antigen (PCNA), caspase-3, α-SMA, and TGF-β1 were assessed. In addition, molecular quantitative PCR and ELISA analyses were performed to identify the expression of mRNAs and related proteins of both caspase-3 and TGF-β1 in prostate tissue from O. majorana-treated and untreated groups. Rats with BPH had significantly higher prostate weights and PI, higher DHT, DNA damage (8-hydroxyguanine, 8-OH-dG), and MDA levels with prominent PCNA, α-SMA, and TGF-β expression, but lower SOD, CAT, and TAC activity and caspase-3 expression. O. majorana (250 and 500 mg/kg/day)-treated groups revealed a decrease in prostate weights and PI, lower levels of DHT, suppressed oxidative stress, reduced tissue proliferation and fibrosis, and restored antioxidant and proapoptotic activity. Additionally, quantitative PCR and ELISA analysis showed that treatment with O. majorana significantly upregulated the expression of caspase-3 and downregulated the expression of TGF-β in prostate tissues of BPH rats. The data were confirmed by the immunohistological reactivity of these targeted markers in the prostate tissues. These effects were more significant with O. majorana 500 mg/mL/rat. In conclusion, the current study indicates the efficient use of O. majorana in the treatment of testosterone-induced BPH through its antiproliferative, proapoptotic, and antioxidative mechanisms.

Abstract
Benign prostatic hyperplasia (BPH) is a common pathology among aging men. Despite the broad pharmacological interventions, the available remedies to treat BPH are yet not devoid of side effects. Herbal compounds are suggested to be an alternative option for the BPH treatment. In our study, we evaluated the effect of kudzu isoflavones and astaxanthin on the BPH animal model. The animals were randomly divided into five groups: control; testosterone-induced BPH group; and three BPH-induced groups, which received intragastrically for 28 days finasteride (5 mg/kg) as a positive control, isoflavones (200 mg/kg), and astaxanthin (25 mg/kg). BPH was induced by castration of animals and subsequent subcutaneous injections of prolonged testosterone (25 mg/kg). Prostate index and histology, biochemical parameters, and antioxidant activity were evaluated. A significant decrease in prostate weight, immunohistochemical markers, and normalization of prostate Ca/Mg ratio was found in all treatment groups. Astaxanthin treatment also resulted in decreased epithelial proliferation and normalized superoxide dismutase activity. In conclusion, both isoflavones and astaxanthin inhibited BPH development at a level comparable to finasteride in terms of prostate weight, prostatic epithelium proliferation, and prostate tissue cumulative histology score. These results suggest that isoflavones and especially astaxanthin could serve as a potential alternative therapy to treat BHP.

Abstract
Epidemiological studies demonstrate that men with periodontitis are also susceptible to benign prostatic hyperplasia (BPH) and that periodontal treatment can improve the prostatic symptom. However, molecular links of this relationship are largely unknown. The goal of the current study was to elucidate the effects of experimental periodontitis on the hyperplasia of prostate and whether oxidative stress and inflammation participated in this process. For this purpose, ligature-induced periodontitis, testosterone-induced BPH, and the composite models in rats were established. Four weeks later, all the rats were sacrificed and the following items were measured: alveolar bone loss and histological examination of periodontal tissues were taken to assess the establishment of periodontitis model, prostate index and histological examination of prostate tissues were taken to test the establishment of the BPH model, inflammatory cytokines in plasma were assessed, and Bax/Bcl-2 proteins related to cell apoptosis were analyzed via western blot analysis. To further investigate whether oxidative stress participates in the aggravation of BPH, in vitro models were also conducted to measure the production of intracellular reactive oxygen species (ROS) and hydrogen peroxide (H2O2) concentration. We found that simultaneous periodontitis and BPH synergistically aggravated prostate histological changes, significantly increased Ki67 proliferation, and reduced apoptosis in rat prostate tissues. Also, our results showed that periodontal ligation induced increased Bcl-2 protein expression, whereas Bax expression was decreased in BPH rats than in normal rats. Compared with the control group, periodontitis and BPH both significantly enhanced inflammatory cytokine levels of TNF-α, IL-6, IL-1β, and CRP. Furthermore, Porphyromonas gingivalis lipopolysaccharide induced enhanced generation of intracellular expression of ROS and H2O2 in BPH-1 cells. Our experimental evidence demonstrated that periodontitis might promote BPH development through regulation of oxidative stress and inflammatory process, thus providing new strategies for prevention and treatment of BPH.

Abstract
Protaetia brevitarsis seulensis is an animal-based medicine used traditionally in China, Japan, and Korea to treat hepatic disorders; it has been shown to possess various pharmacological effects such as antibacterial and antioxidant activities. In this study, we investigated the effects of P. brevitarsis on a testosterone-induced benign prostatic hyperplasia (BPH) rat model. To establish the BPH model, the animals were administered a subcutaneous injection of testosterone daily for 28 days. P. brevitarsis was administered by oral gavage at doses of 12.5, 25, and 50 mg/kg for 28 days, along with testosterone injection. P. brevitarsis treatment markedly decreased the absolute and relative prostate weight of BPH animals. The levels of dihydrotestosterone was reduced in P. brevitarsis-treated animals compared to those in the BPH animals. Histological analysis of the prostate showed that P. brevitarsis treatment effectively suppressed the testosterone-induced hyperplasia of prostatic epithelial cells, which was accompanied by reductions in the PCNA and Ki-67 expressions in prostatic tissues. These results indicate that P. brevitarsis effectively suppresses testosterone-induced development of BPH, and thus, is a potential therapeutic agent for BPH.

Abstract
Prostatitis, defined as a pathological inflammatory change in the prostate tissue, is one of the most prevalent urological conditions in men. However, optimal management of prostatitis remains unclear, and treatment outcomes are unsatisfactory owing to adverse effects. Carica papaya leaf extract (PAL) is known for its antioxidant, immunomodulatory, and anticancer properties; however, evidence of its anti-inflammatory effect in prostatic tissues remains elusive. In this study, the therapeutic effects and underlying molecular mechanisms of PAL in mice with experimental autoimmune prostatitis (EAP) and a prostatic cell line (RWPE-1 cells) exposed to inflammatory conditioned medium were investigated. PAL suppressed pathological alterations in EAP and markedly reduced prostate weight in EAP mice. Histological analysis revealed that PAL alleviates prostatic hyperplasia. Furthermore, PAL significantly reduced cyclooxygenase-2 mRNA and protein expression; production of inflammatory cytokines, including interleukin-6, tumor necrosis factor-α, and transforming growth factor-β; and TRAF6/TAK1/MEK/ERK and NF-κB pathway-related protein expression. TRAF6/TAK1/MEK/ERK and NF-κB pathway-related proteins were upregulated in inflammatory conditioned medium-stimulated RWPE-1 cells, but PAL reduced the expression of these markers. Particularly, PAL treatment suppressed the nuclear translocation of NF-κB p65 and phosphorylation of p65 in RWPE-1 cells exposed to the inflammatory conditioned medium. Collectively, the results demonstrate the anti-proliferative and anti-inflammatory effects of PAL in the experimental prostatitis model, which highlights the potential of PAL as a new therapeutic agent in the treatment of prostatic disease.

Abstract
AIM To investigate the possible modulatory effect of febuxostat in testosterone-induced benign prostatic hyperplasia (BPH) in rats with emphasis on xanthine oxidase (XO)/Janus Kinases (JAK)/signal transducer and activator of transcription (STAT) axis. MAIN METHODS Male Wistar rats were treated with testosterone with/out febuxostat. Effect of febuxostat on BPH was assessed at the structural level by histopathology and determination of prostate weight/index. Cyclin D1 protein expression was assessed immunohistochemically and the ratio of Bax/Bcl-2 mRNA expression was determined by real time polymerase chain reaction analysis (RT-PCR). Besides, uric acid serum level was determined colorimetrically. Prostatic XO activity, as well as oxidative stress and inflammatory markers were evaluated. Additionally, western blot analysis was performed for determination of JAK-1 and phosphorylated form of STAT-3 expression in tissues. KEY FINDINGS Results revealed that febuxostat inhibited the increase in prostatic weight and index compared to testosterone-treated group. Additionally, febuxostat ameliorated testosterone-induced histopathological changes, prevented the rise in cyclin D1 expression and enhanced Bax/Bcl2 ratio. Febuxostat suppressed testosterone induced- increase in XO activity in prostates and serum level of uric acid. Moreover, it regulated oxidative stress markers including; malondialdehyde (MDA), superoxide dismutase (SOD) activity and glutathione (GSH) content. Also, it inhibited the increase in prostate contents of interleukin-6 (IL-6), interleukin-1β (IL-1 β), tumor necrosis factor (TNF-α) and nuclear factor (NF-κB). Interestingly, febuxostat markedly reduced JAK-1 and subsequent phosphorylation of STAT-3 protein expression. SIGNIFICANCE Febuxostat ameliorates testosterone-induced BPH via suppressing XO/JAK/STAT axis. This may help to re-purpose the use of XO inhibitors.

Abstract
Chronic cigarette smoke (CS) exposure induces prostate deficits. We previously found that swertiamarin had prostatic protective potential. This study was to investigate the possible protective effect of swertiamarin against CS-induced prostate dysfunction on human prostate epithelial cells, stromal cells and rats. Rat prostate collagen deposition and fibrosis were assessed by sirius red staining and measuring hydroxyproline content, as well as by qPCR and western blot analysis for fibrotic extracellular matrix components. Prostatic levels of oxidative stress and inflammatory-related factors were also analyzed. In order to explore its underling mechanisms, the activities of Hedgehog signaling pathway and epithelial-mesenchymal transition of human prostate cells and rat prostate tissue were estimated. It was found that swertiamarin ameliorated CS-induced prostatic collagen deposition, relieved oxidative stress and local inflammation, inhibited the activation of Hedgehog signaling pathway and attenuated epithelial-mesenchymal transition. It indicated that swertiamarin could ameliorate CS-induced prostatic fibrosis by inhibiting epithelial-mesenchymal transition and Hedgehog pathway.
