Domosławska-Wyderska A, Zduńczyk S, Rafalska A. Potential role of oxidative stress in pathogenesis of benign prostatic hyperplasia in male dogs. Reprod Domest Anim 2024; 59:e14580. [PMID: 38698701 DOI: 10.1111/rda.14580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Accepted: 04/22/2024] [Indexed: 05/05/2024]
Abstract
The pathogenesis of benign prostatic hyperplasia (BPH) in dogs is still not fully understood. Some studies suggest that oxidative stress may have a potential role in the pathogenesis of BPH in dogs. Age-related hormonal changes may activate a chronic inflammatory response in the prostate. This causes the generation of reactive oxygen species (ROS) and results in oxidative stress. Excessive production of ROS results in DNA damage and hyperplastic transformation of prostatic cells. The use of antioxidants for improvement of treatment outcomes for canine PBH has been discussed. Further research is needed on the importance of oxidative stress in the development of BPH in dogs and the usefulness of antioxidants in the supportive treatment of this condition.

Abstract
Prostatic hyperplasia is very common in elderly men and is a typical disease that reduces quality of life. Histologically, hyperplasia of the prostate gland causes obstruction at the bladder outlet, resulting in symptoms such as a weak urine stream. Various factors have been considered to cause histological enlargement of the prostate, but the underlying cause is still unknown. The factors that cause prostate hyperplasia can be broadly classified into intrinsic and extrinsic ones. Extrinsic factors include things that we directly come into contact with such as bacteria and food. On the other hand, intrinsic factors are those that cause changes in functions originally provided in the body due to some cause, including extrinsic factors, such as chronic inflammation and an imbalance of sex hormones. A large number of reports have been made to date regarding the etiology of prostatic hyperplasia, although they have not yet clarified the fundamental cause(s). The various factors currently known should be outlined for future research. Should it be possible to prevent this highly prevalent prostatic hyperplasia which is mainly cause of dcreasing quality of life, there is no doubt that it would be a huge contribution to humanity.

Prostate 2024; 84:329-341. [PMID: 38073004 DOI: 10.1002/pros.24652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 11/04/2023] [Accepted: 11/16/2023] [Indexed: 01/25/2024]
Abstract
BACKGROUND Chronic prostatitis demonstrates a prevalence rate of nearly 5%-10% among young and middle-aged individuals, significantly affecting their daily lives. Researchers have obtained significant outcomes investigating the anti-inflammatory properties of itaconic acid (IA) and its derivative, 4-Octyl itaconate (4-OI), against diverse chronic inflammatory disorders, such as osteoarthritis and airway inflammation. Nevertheless, whether IA can also exert anti-inflammatory effects in chronic prostatitis requires extensive research and validation. METHODS Human prostate tissues obtained through transurethral prostate resection (TURP) from individuals were divided into three groups based on different levels of inflammation using hematoxylin and eosin staining (H&E). Subsequently, immunohistochemistry (IHC) was employed to detect the expression of immune-responsive gene 1 (IRG-1) in these different groups. The animal experiment of this study induced experimental autoimmune prostatitis (EAP) in nonobese diabetic mice through intradermal prostate antigen injection and complete Freund's adjuvant. Then, the experimental group received intraperitoneal injections of different doses of 4-OI, while the control group received injections of saline. Western blot (WB), H&E staining, and TUNEL staining helped analyze the prostate tissues, while enzyme-linked immunosorbent assay (ELISA) helped evaluate serum inflammatory factors. Reactive oxygen species, superoxide dismutase (SOD), and malondialdehyde (MDA) were assessed for oxidative stress across experimental groups. RESULTS IHC analysis of human prostate tissue depicts that IRG-1 expression enhances as prostate inflammation worsens, highlighting the critical role of IA in human prostatitis. The application of 4-OI increased Nrf2/HO-1 expression while inhibited NLRP3 expression following the WB results, and its application resulted in a decrease in cell pyroptosis in prostate tissue, demonstrated by the results of TUNEL staining. Administering a Nrf2 inhibitor ML385 1 h before intraperitoneal injection of 50 mg/kg 4-OI reversed the previous conclusion, further confirming the above conclusion from another perspective. Meanwhile, the ELISA results of serum inflammatory factors (IL-1β, IL-6, and TNF-α), as well as the measurements of oxidative stress markers MDA and SOD, further confirmed the specific anti-inflammatory effects of 4-OI in EAP. CONCLUSIONS The present study indicates that 4-OI can alleviates EAP by inhibiting the NLRP3 inflammasome-induced pyroptosis through activating Nrf2/HO-1 pathway, which may facilitate a novel approach toward prostatitis treatment.

Oxidative stress, free radicals and antioxidants: potential crosstalk in the pathophysiology of human diseases. Front Chem 2023; 11:1158198. [PMID: 37234200 PMCID: PMC10206224 DOI: 10.3389/fchem.2023.1158198] [Citation(s) in RCA: 37] [Impact Index Per Article: 37.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 04/26/2023] [Indexed: 05/27/2023] Open
Abstract
Introduction: Free radicals are reactive oxygen species that constantly circulate through the body and occur as a side effect of many reactions that take place in the human body. Under normal conditions, they are removed from the body by antioxidant processes. If these natural mechanisms are disrupted, radicals accumulate in excess and contribute to the development of many diseases. Methodology: Relevant recent information on oxidative stress, free radicals, reactive oxidative species, and natural and synthetic antioxidants was collected by researching electronic databases such as PubMed / Medline, Web of Science, and Science Direct. Results: According to the analysed studies, this comprehensive review provided a recent update on oxidative stress, free radicals and antioxidants and their impact on the pathophysiology of human diseases. Discussion: To counteract the condition of oxidative stress, synthetic antioxidants must be provided from external sources to supplement the antioxidant defense mechanism internally. Because of their therapeutic potential and natural origin, medicinal plants have been reported as the main source of natural antioxidants phytocompounds. Some non-enzymatic phytocompounds such as flavonoids, polyphenols, and glutathione, along with some vitamins have been reported to possess strong antioxidant activities in vivo and in vitro studies. Thus, the present review describes, in brief, the overview of oxidative stress-directed cellular damage and the unction of dietary antioxidants in the management of different diseases. The therapeutic limitations in correlating the antioxidant activity of foods to human health were also discussed.

Abstract
PURPOSE Tomato is an important source of lycopene, a carotenoid that has been emerging as a natural preventive agent for prostate disease. Moreover, tomato contains other components with a wide range of physiological properties, but their potential beneficial effects on prostatic hyperplasia (PH) during obesity have not been completely established. In this study, we compared the effect of a lipidic extract of tomato saladette (STE) with Serenoa repens (SR) on obese rats with PH. METHODS Forty-eight Wistar rats were divided in Control (C) and Obese (Ob) treated without (n = 12) and with (n = 36) testosterone enanthate (TE), once a week for 8 weeks to induce PH. After 4 weeks, SR and STE were administered. Biochemical parameters, oxidative stress markers and inflammatory cytokines production were determined. RESULTS TE increased prostate weight and caused prostatic hyperplasia in C group, and these effects were exacerbated by obesity. SR and STE reverted the increase in prostate weight and hyperplasia caused by TE in C and Ob groups. Obesity increased LDL, TGs, NOx and MAD, but decreased HDLc, GSx, SOD and CAT. SR reverted the effects of obesity, but these were significantly reduced and HDLc increased with STE. Obesity and TE increased TNFα, IL-1β and IL-6 levels, but these were partially reverted by STE compared with SR. CONCLUSIONS Excess of fat tissue increases the alterations by PH. STE diminishes these alterations compared with SR, suggesting its beneficial effect to improve prostate function. Whole tomato lipid extract could serve as sole therapy or as an adjunct to pharmacological treatment for PH.

Pain Res Manag 2023; 2023:7754876. [PMID: 36960418 PMCID: PMC10030225 DOI: 10.1155/2023/7754876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 09/25/2022] [Accepted: 03/04/2023] [Indexed: 03/16/2023]
Abstract
Background Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex male dysfunction, mostly seen in young and middle-aged men with a history of more than 3 months. As a traditional therapy of Traditional Chinese Medicine, acupuncture has been proven an effective method to treat CP/CPPS in recent years. Though some meta-analyses on acupuncture for chronic prostatitis were published in 2018 and 2019, most of the included studies were low in quality according to the JADAD score (JADAD < 4). The conclusions of acupuncture for CP/CPPS remain indefinite. Purpose This review aims to evaluate the efficacy of acupuncture for CP/CPPS by including high-quality literature only (JADAD ≥ 4) to provide a reliable basis for clinical applications and research. Method Nine electronic databases were searched from inception to March 1, 2022, and only randomized controlled trials (RCT) with high-quality (JADAD ≥ 4) were included. Data were analyzed using Review Manager 5.3. and was verified through trial sequential analysis (TSA). We carried out a sensitivity analysis for the heterogeneity (I 2 ≥ 50%). Publication bias was explored using a funnel plot. Result Ten RCTs (11 trials) of high-quality methodology involving 798 patients were included. Meta-analysis showed that compared to sham acupuncture (SAT) and western medicine (WM), acupuncture (AT) played superior roles for CP/CPPS patients in pain score, NIH-CPSI score, quality of life score, urinary symptom, and efficacy rate. As for the adverse effects, 4 RCTs described mild hematoma and pain in AT and SAT groups, while specific symptoms including nausea, abdominal pain, dizziness, and low blood pressure were reported in WM groups. Conclusion This meta-analysis indicated that acupuncture has measurable benefits on CP/CPPS, and security has also been ensured. However, this meta-analysis only included 10 RCTs; thus, RCTs with a larger sample size and longer-term observation are required to verify the effectiveness of acupuncture further in the future.

Abstract
BACKGROUND The aim of this study was to evaluate total antioxidant capacity (TAC) and biomarkers of lipid and protein peroxidation in the blood serum of dogs with benign prostatic hyperplasia (BPH). The study was conducted on 36 intact male dogs of various breeds. The dogs were assigned to two groups: BPH group (n = 18) and non-affected group (n = 18). Blood samples were collected from the cephalic vein. The antioxidant status of the serum was assessed using TAC. The levels of bityrosine, formylkynurenine and SH-groups were used as protein peroxidation biomarkers and the level of radical cations of N,N-diethyl-paraphenylene diamine (RC-DEPPD) was used as a marker for lipid peroxidation. TAC and the concentrations of SH-groups and RC-DEPPD in the serum were determined spectrophotometrically, the concentrations of bityrosine and formylokynurenine, were determined using spectrofluorimetric methods. RESULTS The mean value of TAC in the serum was significantly lower (P = 0.01) in BPH dogs than in non-affected dogs (3.10 ± 0.56 vs 4.20 ± 1.60 μmol/g protein). Mean levels of protein and lipid oxidation biomarkers showed a trend towards oxidative imbalance, but there were no statistically significant differences between dogs with BPH and controls (P > 0.05). CONCLUSION In conclusion, significantly lower serum TAC in dogs with BPH compared to non-affected dogs suggests a potential involvement of oxidative stress in the pathogenesis of BPH in dogs. More studies are needed to clarify the role of oxidative stress in the development of BPH in dogs.

Antioxidants (Basel) 2022; 11:antiox11071234. [PMID: 35883725 PMCID: PMC9312030 DOI: 10.3390/antiox11071234] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 06/16/2022] [Accepted: 06/21/2022] [Indexed: 01/12/2023] Open
Abstract
Flavonoids and proanthocyanidins (PACs) have been the subject of intense scientific investigations, both for their antioxidant properties and anti-adhesion activity against uropathogenic bacteria. We investigated the metabolomics and antioxidant capacity of SP4TM, a patent-pending formulation based on a mixture of plant extracts with a high content of bioactive PACs and other polyphenols. The total content of polyphenols (885.51 ± 14.19 mg/g), flavonoids (135.52 ± 8.98 mg/g), anthocyanins (54.84 ± 2.97 mg/g), and PACs (379.43 ± 12.44 mg/g) was quantified using UV-Vis assays. Use of HPLC-ESI-MS/MS revealed the presence of 5 flavanols (100.77 ± 3.90 mg g−1 d.wt), 11 flavonols (59.96 ± 1.83 mg g−1 d.wt), and 8 anthocyanins (46.96 ± 1.59 mg g−1 d.wt), whereas MALDI-TOF MS showed that SP4TM contains PACs with one or more type-A interflavan bonds at each degree of polymerization. Regarding antioxidant properties, LUCS technology on HepG2 cells evidenced the ability of SP4TM to neutralize intracellular free radicals, inhibit membrane lipid peroxidation, quench H2O2, and reduce free radicals mainly through chelating mechanism, as demonstrated by a higher FRAP value (2643.28 ± 39.86 mmol/g) compared with ABTS (139.92 ± 6.16 mmol/g) and DPPH (89.51 ± 3.91 mmol/g). Finally, the SP4TM type-A PAC content strongly prevented bacterial adhesion of P-fimbriated uropathogenic Escherichia coli (0.23 mg/mL). In conclusion, SP4TM has a strong antioxidant capacity involving multitarget mechanisms and is a potential supplement to fight urinary tract infections due to its ability to inhibit uropathogenic E. coli adhesion.

Abstract
Overproduction of reactive oxygen species (ROS) and superlative lipid peroxidation promote tumorigenesis, and mitochondrial aldehyde dehydrogenase 2 (ALDH2) is associated with the detoxification of ROS-mediated lipid peroxidation-generated reactive aldehydes such as 4-hydroxy-2-nonenal (4-HNE), malondialdehyde, and acrolein due to tobacco smoking. ALDH2 has been demonstrated to be highly associated with the prognosis and chemoradiotherapy sensitivity of many types of cancer, including leukemia, lung cancer, head and neck cancer, esophageal cancer, hepatocellular cancer, pancreatic cancer, and ovarian cancer. In this study, we explored the possible relationship between ALDH2 and urological cancers from the aspects of ferroptosis, epigenetic alterations, proteostasis, mitochondrial dysfunction, and cellular senescence.

Abstract
This study investigates the inhibitory effect of astaxanthin (AST) on testosterone-induced benign prostatic hyperplasia (BPH) in rats. Except for the sham operation, BPH model rats were randomly assigned to five groups: the BPH model control rats, AST-treated BPH model rats (20 mg/kg, 40 mg/kg, and 80 mg/kg), and epristeride (EPR)-treated BPH model rats. After treatment, as compared with the BPH model control rats, the prostate and ventral prostate weights of the AST-treated rats decreased, while there was a marked decline in the 80 mg/kg AST-treated rats. The same effect was also observed in the prostate index and ventral prostate index. The proliferation characteristics of epithelia observed in the BPH model control group were gradually alleviated in the AST-treated rats. As compared with the BPH model control rats, lower epithelial thicknesses of prostates and fewer secretory granules in epithelia were observed in the AST-treated rats. The superoxide dismutase (SOD) activity of prostates increased in all the AST-treated rats with a significant increase in the 40 mg/kg and 80 mg/kg AST-treated rats. The testosterone (T) and dihydrotestosterone (DHT) levels of prostates in the AST-treated groups were lower than those in the BPH model control group, and a significant decline was found in the T level of prostates in the 40 g/kg and 80 mg/kg AST-treated rats and the DHT level of prostates in the 40 mg/kg AST-treated rats. These results indicate that AST might have an inhibitory effect on T-induced BPH in rats, possibly due to SOD activity regulation and T and DHT levels.

Background The Prinsepia utilis Royle leaves (P. utilis) is a folk herb used for benign prostatic hyperplasia (BPH) control by ethnic minorities for centuries in China with rich in resources. Our previous studies have confirmed the anti-BPH effect of its water extract (QCJ) and the active fraction (Fr. B) separated from the QCJ by animal test. The Fr. B from P. utilis should be a potential candidate for BPH control. Methods In this study, the chemical ingredients of Fr. B were identified by UPLC-QTOF-MS, and quantified by HPLC. Murine animal models were divided into 8 groups, Sham rats, BPH rats, BPH rats administered with finasteride (1 mg/kg), BPH rats administered with Pule’an (460 mg/kg), BPH rats administered with low, high dosage of QCJ (860 mg/kg, 2580 mg/kg respectively), BPH rats administered with low, high dosage of Fr. B (160 mg/kg, 480 mg/kg respectively). The expression of vascular endothelial growth factor (VEGF) in the prostate tissue of rats was tested, and serum levels of dihydrotestosterone (DHT), testosterone (T), estradiol (E2), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and total superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT), malondialdehyde (MDA) in prostate homogenate were measured. One-way ANOVA followed by LSD was used for statistical analysis. Results The BPH rats treated by Fr. B exhibited significant reductions of VEGF and MDA levels, as well as significant increases of SOD, GSH-Px and CAT in the prostate tissue after 28 day administration (P < 0.05). Moreover, Fr. B significantly reduced DHT, DHT/E2 ratio, TNF-α, while increased T levels in serum of BPH rats (P < 0.05). UPLC-QTOF-MS analysis revealed 10 flavonoids as the key constituents of this fraction, which accounted for 54.96% of all substance of Fr. B. The relative contents of compound 1, 2 are 11.1%, 13% in Fr. B respectively. Conclusions These results indicated that the Fr. B obtained from P. utilis alleviated the symptoms of BPH rats through multiple mechanisms including reduction of DHT/E2 ratio, inhibition of growth factor, anti-inflammation and anti-oxidation, in which flavonoids might be the key constituents. It supported the hypothesis that the Fr. B should be further explored as a candidate for BPH patients.

Abstract
Pharmacological treatment for BPH includes 5-α reductase inhibitors as Finasteride and Dutasteride as a monotherapy or in combination with antimuscarinic drugs, alpha-blockers, 5-phosphodiesterase inhibitor drugs. Androgen receptor inhibitors revealed several adverse events as decreased libido, erectile dysfunction, ejaculatory dysfunction, and gynecomastia. Hence, the emergence of complementary and alternative medications having safety profile—preferably, edible natural products—would be highly desirable. In-silico studies based on Maestro Molecular Modelling platform (version 10.5) by Schrӧdinger, LLC was used to identify the lead molecules. The in-vivo activity studied on rats gave the positive results. The findings based on experiments as antioxidant parameters showed the potential to quench the free radicals. The significant results were also seen in prostatic index and histopathological studies supported the above findings. Based on these data, sesamol and derivative have proven efficacy in protecting against testosterone induced BPH.

Abstract
All men, almost, suffer from prostatic disorders in average life expectancy. In the year of 1950s, the first autopsy of prostate gland discovered the link between Benign prostatic hyperplasia (BPH) and Prostate Cancer (PCa). After that, many histology, biochemistry, epidemiology studies explained the association and associated risk factor for the same. From the various scientific evidence, it is proved that both diseases share some common transcription factors and signalling pathways. Still, BPH cannot be considered as the first step of PCa progression. To define, the relationship between both of the diseases, a well-defined large epidemiological study is needed. Along with androgen signalling, imbalanced apoptosis, oxidative stress, and microbial infection also crucial factors that significantly affect the pathogenesis of BPH. Various signalling pathways are involved in the progression of BPH. Androgen signalling is the driving force for the progress of PCa. In PCa androgen signalling is upregulated as compared to a healthy prostate. Some dominant Androgen-regulated genes and their functions have been discussed in this work.

Abstract
Mechanisms of the brain-related comorbidities in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) are still largely unknown, although CP/CPPS is one of the major urological problems in middle-aged men, while these neuropsychological incapacities considerably diminish life quality. The objectives of this study were to assess behavioral patterns in rats with CP/CPPS and to determine whether these patterns depend on alterations in the brain oxidative stress, corticosterone, and hippocampal parvalbumin-positive (PV+) interneurons. Adult male Wistar albino rats from CP/CPPS (intraprostatic injection of 3% λ-carrageenan, day 0) and sham (0.9% NaCl) groups were subjected to pain and anxiety-like behavior tests (days 2, 3, and 7). Afterwards, rats were sacrificed and biochemical and immunohistochemical analyses were performed. Scrotal allodynia and prostatitis were proven in CP/CPPS, but not in sham rats. Ethological tests (open field, elevated plus maze, and light/dark tests) revealed significantly increased anxiety-like behavior in rats with CP/CPPS comparing to their sham-operated mates starting from day 3, and there were significant intercorrelations among parameters of these tests. Increased oxidative stress in the hippocampus, thalamus, and cerebral cortex, as well as increased serum corticosterone levels and decreased number of hippocampal PV+ neurons, was shown in CP/CPPS rats, compared to sham rats. Increased anxiety-like behavior in CP/CPPS rats was significantly correlated with these brain biochemical and hippocampal immunohistochemical alterations. Therefore, the potential mechanisms of observed behavioral alterations in CP/CPPS rats could be the result of an interplay between increased brain oxidative stress, elevated serum corticosterone level, and loss of hippocampal PV+ interneurons.

Abstract
Benign prostatic hyperplasia (BPH) is a serious illness affecting middle-aged and elderly male patients. It is a complication of several diseases including metabolic syndrome. BPH has been associated with inflammation and increased oxidative stress in prostatic tissues. Piceatannol (PIC) is an active natural polyhydroxylated stilbene found in many plants. It has profound anti-inflammatory as well as antioxidant activities. However, it suffers relatively poor pharmacokinetic properties. Nanoformulation is an acknowledged approach to improve PIC bioavailability. The goal was to evaluate the ability of PIC in preventing testosterone-induced benign prostatic hyperplasia in rats. PIC was prepared in a self-nanoemulsifying drug delivery system (SNEDDS). Animals were placed into seven groups: 1) control (vehicle), 2) PIC SNEDDS (20 mg/kg), 3) testosterone (3 mg/kg), 4) testosterone + PIC SNEDDS (5 mg/kg), 5) testosterone + PIC (10 mg/kg), 6) testosterone + PIC SNEDDS (20 mg/kg) and 7) testosterone + finasteride (5 mg/kg). Testosterone was injected SC while PIC SNEDDS and finasteride were given orally. All treatments were given once daily, 5 days/week for four consecutive weeks. PIC administration ameliorated increased prostate weights and indices in addition to histopathological alterations. Further it inhibited accumulation of lipid peroxidation, depletion of glutathione (GSH) and exhaustion of catalase (CAT). PIC SNEDDS exhibited anti-proliferative activities as demonstrated by the inhibition of cyclin D1 protein expression and Bcl2 mRNA expression in addition to enhancement of Bax mRNA expression and caspase-3 content. Immunohistochemically, PIC SNEDDS protected against the testosterone-induced increased expression of tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), nuclear factor kappa B (NFκB) and also offered protection against the decline in Nrf2 expression. Further, a significant enhancement of Nfe212 and Homx1 mRNA expression was detected in PIC SNEDDS-treated animals in comparison to the testosterone group. Conclusively, PIC prepared in SNEDDS protects against experimentally induced BPH via modulation of, at least partly, Nrf2/HO-1/NFκB axis.

Abstract
PURPOSE We have aimed to determine whether oxidants-antioxidants play a role in the etiopathogenesis of bladder tumour by measuring their levels in the serums of patients with bladder tumour. MATERIAL METHOD Thirty patients with bladder tumour with superficial bladder tumour and 27 normal healthy volunteers were included in the study. Four cc of venous blood was taken from these patients and volunteers in the control group and centrifuged at 5000 rpm for 10 minutes and divided into serum and plasma. The activities of xanthine oxidase, glutathione reductase, glutathione-s transferase, reduced glutathione and superoxide dismutase enzymes in serum were then measured spectrophotometrically. FINDINGS Antioxidant parameters (glutathione-s-transferase, reduced glutathione, superoxide dismutase and glutathione reductase) in the serum of patients with bladder tumours were found statistically significantly lower than control group (p < .05). On the other hand, xanthine oxidase which is an oxidant indicator, was found significantly higher in patients with bladder cancer than control group (p < .05). CONCLUSION Oxidative stress is effective in the etiopathogenesis of bladder tumour. We, therefore, believe that antioxidants are protective against bladder tumours and will be effective in the treatment of bladder tumours.

Abstract
The antioxidant activity of natural compounds consists in their ability to modulate gene and protein expression, thus inducing an integrated cell protective response and repair processes against oxidative stress. New screening tools and methodologies are crucial for the actual requirement of new products with antioxidant activity to boost endogenous oxidative stress responsive pathways, Reactive Oxygen Species (ROS) metabolism and immune system activity, preserving human health and wellness. In this study, we performed and tested an integrated oxidative stress analysis, using DPPH assay and PNT2 cells injured with DPPH. We firstly investigated the mechanism of action of the oxidising agent (DPPH) on PNT2 cells, studying the variation in cell viability, oxidative stress genes, inflammatory mediator and ROS levels. The results reveal that DPPH activated ROS production and release of Prostaglandin E2 in PNT2 at low and intermediate doses, while cells switched from survival to cell death signals at high doses of the oxidising agent. This new in vitro oxidative stress model was validated by using Trolox, β-carotene and total extract of the green microalga Testraselmis suecica. Only the T. suecica extract can completely counteract DPPH-induced injury, since its chemical complexity demonstrated a multilevel protecting and neutralising effect against oxidative stress in PNT2.

Abstract
Benign prostatic hyperplasia (BPH) is a widespread disorder in elderly men. Cinnamaldehyde, which is a major constituent in the essential oil of cinnamon, has been previously reported to reduce xanthine oxidase activity, in addition to its anti-inflammatory, anti-oxidant, and anti-proliferative activities. Our study was designed to investigate the potential modulatory effects of cinnamaldehyde on testosterone model of BPH in rats through reduction of uric acid level, and suppression of IL-6/JAK1/STAT3 signaling pathway. Cinnamaldehyde (40 and 75 mg/kg) was orally administered to male Wistar rats for 3 weeks, and concurrently with testosterone (3 mg/kg, s.c.) from the second week. Cinnamaldehyde ameliorated the elevation in prostatic weight and index compared to rats treated with testosterone only, that was also confirmed by alleviation of histopathological changes in prostate architecture. The protective mechanisms of cinnamaldehyde were elucidated through inhibition of xanthine oxidase activity and reduced uric acid level. That was accompanied by reduction of the pro-inflammatory cytokines; interleukin-6 (IL-6), IL-1β, tumor necrosis factor-alpha (TNF-α), and the nuclear translocation of the transcription factor NF-κB p65, that could be attributed also to the enhanced anti-oxidant defense by cinnamaldehyde. The protein expression of JAK1, which is IL-6 receptor linked protein, was reduced with subsequently reduced activation of STAT3 protein. That eventually suppressed the formation of the proliferation protein cyclin D1, while elevated Bax/Bcl2 ratio. It can be concluded that reducing uric acid level through xanthine oxidase inhibition and suppression of the inflammatory signaling cascade; IL-6/JAK1/STAT3; by cinnamaldehyde could be a novel and promising therapeutic approach against BPH.

Abstract
Protocatechuic acid (PA) is a polyphenol-recognized for its efficacy as an antioxidant-possesses anticancer, anti-inflammatory, antioxidant properties. The efficacy of PA in the management of benign prostatic hyperplasia (BPH) has not been investigated. Forty-two castrated rats (n = 7) were treated as follows: control (corn oil), BPH only received testosterone propionate (TP) (TP 3 mg/kg intraperitoneally), BPH + PA (TP 3 mg/kg + PA 40 mg/kg), BPH + finasteride (Fin) (TP 3 mg/kg + Fin 10 mg/kg), PA only (40 mg/kg: by gavage), and Fin only (10 mg/kg: by gavage) for 4 weeks. In BPH rats, there were significant (P < .05) increases in prostatic (250%) and organosomatic (280%) weights compared with controls. Cotreatment decreased prostatic weights by 19% (PA) and 21% (Fin). Markers of inflammation: myeloperoxidase activities increased in serum (148%) and prostate (70%), as well as nitric oxide levels serum (92%) and prostatic (95%). Proinflammatory cytokines interleukin-1β and tumor necrosis factor-α increased by 3.6- and 2.8-fold. Furthermore, prostatic malondialdehyde, superoxide dismutase, and serum total acid phosphatase increased by 97%, 25%, and 48%, respectively. Histology revealed poor architecture and severe proliferation of the prostate in BPH rats. Inflammation and oxidative stress markers, as well as the histological alteration in BPH rats, was attenuated (P < .05) upon cotreatment with PA and comparable with Fin cotreatment. These results suggest that PA mitigates oxido-inflammatory responses and restored prostatic cytoarchitecture to levels comparable with control in rats induced with BPH.

Abstract
BACKGROUND There is some evidence that Benign Prostatic Hyperplasia (BPH) may increase the risk of developing prostate cancer, so conducting research on effective BPH inhibitors is important. OBJECTIVE This research studied the inhibitory effect of Iodized Serum Milk Protein (ISMP) on BPH in rats. ISMP is a concentrate of lactic protein containing 2.2% iodine. METHODS Male Wistar rats, aged 18 months, were used. In the intact control group, sunflower oil was administered intragastrically by gavage. In 36 rats, BPH was induced by surgical castration, followed by subcutaneous injections of prolonged testosterone - omnadren, 25mg/kg every other day (7 administrations). One group of rats served as BPH-control. ISMP and finasteride (positive control), dissolved in sunflower oil, were administered to rats intragastrically daily at a dose of 200μg/kg and 5mg/kg, respectively, for 4 weeks starting immediately after castration. RESULTS ISMP inhibited the development of BPH in rats, significantly reducing the mass of the prostate and its parts (except for the anterior lobes) by 1.1-1.3 times and the prostatic index (the ratio of prostate weight to the body weight) - by 1.3-1.4 times. Finasteride inhibited the development of BPH, and its activity was higher (by 1.1-1.3 times) than in ISMP. Histological analysis of the prostate showed fewer pronounced morphological hyperplasia signs in animals treated with ISMP or finasteride. CONCLUSION The iodine-containing preparation ISMP has the ability to inhibit the development of BPH in rats although its activity is somewhat lower than that of finasteride.

Ercan M, Alp HH, Kocaturk H, Bakan N, Gul M. Oxidative stress before and after surgery in benign prostatic hyperplasia patients. Andrologia 2019; 51:e13326. [PMID: 31158928 DOI: 10.1111/and.13326] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2019] [Revised: 04/07/2019] [Accepted: 05/01/2019] [Indexed: 01/15/2023] Open
Abstract
The aim was to assess oxidative stress in benign prostatic hyperplasia patients and also to evaluate the effect of operation in late (60 days) post-operative period. This study was conducted with 16 patients with benign prostatic hyperplasia and 16 healthy subjects. Serum malondialdehyde, blood 8-hydroxy-2'-deoxyguanosine/deoxyguanosine, erythrocyte superoxide dismutase, serum total coenzyme Q10 and coenzyme Q10 levels were measured. Independent samples t test was used to analyse the differences between control group and patients, while paired t test was used to analyse the differences between pre-operative and post-operative periods. Malondialdehyde and total coenzyme Q10 levels were lower in patients, while 8-hydroxy-2'-deoxyguanosine/deoxyguanosine level was increased. However, superoxide dismutase activity and coenzyme Q10 levels did not differ. After 60 days of operation, 8-hydroxy-2'-deoxyguanosine/deoxyguanosine and superoxide dismutase activity decreased, while total coenzyme Q10 level increased. However, malondialdehyde and coenzyme Q10 levels were not affected. The international prostate symptom scores of the patients were also decreased after the operation. The results suggest that blood 8-hydroxy-2'-deoxyguanosine/deoxyguanosine level may reflect the oxidative stress better than the malondialdehyde level, and surgical operation attenuates the oxidative stress in late post-operative period in benign prostatic hyperplasia patients.

Periprostatic Adipose Tissue Favors Prostate Cancer Cell Invasion in an Obesity-Dependent Manner: Role of Oxidative Stress. Mol Cancer Res 2019; 17:821-835. [PMID: 30606769 DOI: 10.1158/1541-7786.mcr-18-0748] [Citation(s) in RCA: 68] [Impact Index Per Article: 13.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2018] [Revised: 10/02/2018] [Accepted: 12/19/2018] [Indexed: 11/16/2022]
Abstract
Prostate gland is surrounded by periprostatic adipose tissue (PPAT), which is increasingly believed to play a paracrine role in prostate cancer progression. Our previous work demonstrates that adipocytes promote homing of prostate cancer cells to PPAT and that this effect is upregulated by obesity. Here, we show that once tumor cells have invaded PPAT (mimicked by an in vitro model of coculture), they establish a bidirectional crosstalk with adipocytes, which promotes tumor cell invasion. Indeed, tumor cells induce adipocyte lipolysis and the free fatty acids (FFA) released are taken up and stored by tumor cells. Incubation with exogenous lipids also stimulates tumor cell invasion, underlining the importance of lipid transfer in prostate cancer aggressiveness. Transferred FFAs (after coculture or exogenous lipid treatment) stimulate the expression of one isoform of the pro-oxidant enzyme NADPH oxidase, NOX5. NOX5 increases intracellular reactive oxygen species (ROS) that, in turn, activate a HIF1/MMP14 pathway, which is responsible for the increased tumor cell invasion. In obesity, tumor-surrounding adipocytes are more prone to activate the depicted signaling pathway and to induce tumor invasion. Finally, the expression of NOX5 and MMP14 is upregulated at the invasive front of human tumors where cancer cells are in close proximity to adipocytes and this process is amplified in obese patients, underlining the clinical relevance of our results. IMPLICATIONS: Our work emphasizes the key role of adjacent PPAT in prostate cancer dissemination and proposes new molecular targets for the treatment of obese patients exhibiting aggressive diseases.

Abstract
Benign prostate hypertrophy (BPH) is among the most common diseases with a huge impact on the quality of life of elderly men. There is a current need for the development of well-tolerated and effective preventive strategies to improve the clinical outcome. Caffeic acid phenethyl ester (CAPE) is an important active ingredient isolated from honey-bee propolis with potent anti-proliferative, anti-inflammatory and antioxidant effects. These properties promote CAPE as a promising candidate to be tested as an alternative therapy for BPH, which is still uninvestigated. Herein, we tested the ability of CAPE to guard against testosterone-induced BPH and investigated the involvement of IGF1-R/Akt/β-catenin signaling as a protective mechanism in testosterone-induced BPH rat model. Treatment with CAPE reduced testosterone-induced increase in the prostate index and histopathological alterations. In addition, co-treatment with CAPE significantly suppressed insulin-like growth factor-1 receptor (IGF-1R)/Akt/β-catenin/cyclinD1 axis as well as tumor necrosis factor-α level and nuclear factor (NF)-kB activity. Furthermore, the treatment with CAPE replenished the antioxidant defense systems, superoxide dismutase (SOD) and reduced glutathione (GSH) with subsequent reduction in prostate tissue lipid peroxides. This study highlights the potential merit of CAPE-enriched propolis formulations to protect elderly men against the development of BPH. © 2018 IUBMB Life, 70(6):519-528, 2018.
