Abstract
The effects of acupuncture on the protein and gene expression of oestrogen receptors (ERs) alpha (α) and beta (β) in testosterone-induced benign prostatic hyperplasia (BPH) in rats remains unclear. In this study, rats were randomly divided into four groups (n = 10 per group). The rats in the blank group did not receive any treatment, while the rats in the model group were injected intraperitoneally with testosterone propionate for 28 days to establish the BPH model and then randomly sub-divided into a control group, an acupuncture group and a finasteride group (positive control group). Dissections were performed after rats were anesthetized with isoflurane, and then the weight and volume of the prostate were then measured. The expression of ERs was detected via immunohistochemistry, western blot and real-time polymerase chain reaction. The results showed that ERα was discontinuously distributed in epithelial cells and expressed in large quantities in stromal cells, and ERβ was aggregated and expressed in hyperplastic nodules. Acupuncture and finasteride could significantly improve the distribution of ERα and ERβ which suggested that acupuncture and finasteride could improve BPH. There was no significant difference in ERα messenger ribonucleic acid (mRNA) expression among the groups, but the ERβ mRNA expression in the finasteride group showed a significant difference compared with the control and acupuncture groups. The mechanism of the acupuncture treatment of BPH may be related to the increased transcription level of ERβ mRNA in prostate tissues, the improved distribution of ERα expression in epithelial cells and the aggregation expression of ERs in hyperplastic nodules.

Abstract
Phytochemical investigation of the aerial part of Laportea bulbifera (Siebold & Zucc.) Wedd. (L. bulbifera) showed the isolation of seventeen compounds, including five flavonoids (1-4 and 6), one terpenoid (5), five phenolic acids (7-11), one coumarin (12), two steroids (13-14), and three alkaloids (15-17). Structure elucidations of these compounds were performed on the basis of extensive NMR experiments and compared with the published data in the references. It is remarkable that compounds (3-5) were firstly isolated from the Urticaceae family, compounds (3-8, 11 and 15-17) were firstly obtained from genus Laportea. Furthermore, the result of the chemotaxonomic significance discussion showed that compounds (2-4) may can be served as compound fingerprints to distinguish between species of L. bulbifera and genus Urtica, and what' more, we proposed a bold conjecture that isoflavones can distinguish between species of L. bulbifera and genus Urtica. At the same time, the molecular docking method was used to evaluate the inhibitory effect of these compounds on human steroid 5α-reductase 2 (SRD5α2). The results showed that compounds (1-4 and 6) had better expected effects than the positive drug finasteride can by effectively binding to the active sites of SRD5α2. This study assisted in the future phytochemical and chemotaxonomic research on genus Laportea. Simultaneously, this research provided the theoretical evidence for the application of L. bulbifera in treating benign prostatic hyperplasia (BPH).

Res Rep Urol 2022; 14:225-239. [PMID: 35651598 PMCID: PMC9150786 DOI: 10.2147/rru.s365598] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Accepted: 05/07/2022] [Indexed: 12/17/2022] Open
Abstract
Introduction Benign prostatic hyperplasia (BPH) is a major chronic disease affecting men, and the therapeutic agents currently used to manage it have significant side effects. As a result, an alternative medicine with improved therapeutic properties with no side effects is desperately needed. The current investigation aims to study whether the Caesalpinia bonduc seed extracts (ethanolic-A, hydroalcoholic-B, and aqueous-C) have inhibitory potential on testosterone propionate (TP)-induced BPH in Wistar rats. Methods Wistar rats (male) were randomly allocated to one of five groups: control, BPH (TP-3 mg/kg, subcutaneously daily), low dose (TP + C. bonduc seed extracts – 200 mg/kg body weight), high dose (TP + C. bonduc seed extracts – 400 mg/kg body weight), and standard drug (TP + finasteride – 10 mg/kg body weight). At the end of drug treatment, the rats were sacrificed and their serum and prostates were taken for biochemical and histological studies. Results C. bonduc seed extracts treatment significantly decreased prostate weight and prostatic index in rats with TP-induced BPH. The seed extracts exhibited a potent inhibitory effect on dihydrotestosterone (DHT) in serum and prostate. In addition, the PSA level in the serum showed a noteworthy decrease in comparison with the BPH group. Histopathological examination also indicated that extracts improved the tissue morphology of the prostate significantly. Out of three extracts tested, ethanolic and hydroalcoholic extract recorded significant effect. Finally, liquid chromatography quadrupole time-of-flight mass spectrometry (LC/MS-QTOF) analysis showed that the major compounds present in the extracts were tocopherols, fucosterol, linoleic acid, β-amyrin, β-sitosterol, campesterol, cassane furanoditerpene, norcassane furanoditerpene and other diterpenes. Conclusion Thus, C. bonduc seed extracts could be a potential source for the formulation of new drug for managing BPH. To the best of our knowledge, this is the first scientific animal investigation into the use of C. bonduc seed extract for the management of BPH.

Abstract
Purpose Radiotherapy is one of the most common treatments for prostate cancer. Finding a useful predictor of the therapeutic outcome is crucial as it increases the efficacy of treatment planning. This study investigated the individual susceptibility to radiation based on chromosome 1 aberration frequency measured by the FISH (fluorescence in situ hybridization) method. Patients and Methods Whole blood samples were collected from 27 prostate cancer (PCa) patients and 32 subjects with benign prostatic hyperplasia (BPH), who were considered as a control group. Samples were irradiated with 2 Gy of x-rays, cultured, harvested, and used in the FISH procedure. Results After irradiation, significantly higher levels of all studied chromosome 1 aberrations (except for deletions) in the group of PCa patients were revealed. Furthermore, in the lymphocytes of cancer patients, nearly five-fold higher frequencies of acentric fragments were observed compared to the BPH group. The highest individual radiosensitivities for all estimated biomarkers were seen in PCa patient cells who reported cancer incidence in the immediate family (CIF+). Conclusion The differences in chromosome 1 aberrations between PCa and BPH demonstrate that lymphocytes taken from patients with prostate cancer have higher radiosensitivity which might be related to hereditary or familiar inclinations. Therefore, this technique may find future application in searching biomarkers of the cellular radiotherapy response in prostate cancer patients.

Abstract
Green tea is among the most popular beverages in the world and is an important source of phytoestrogens. Epigallocatechin‑3‑gallate (EGCG) is the major polyphenol in green tea. The aim of this study was to investigate the anti-benign prostatic hyperplasia (BPH) activity and underling mechanisms of EGCG in testosterone-induced BPH rats and in BPH-1 cells. Prostatic levels of oxidative stress and inflammation makers, as well as angiogenesis related growth factors were measured. Additionally, the prostatic levels of sex hormonal mediators (androgen receptor (AR), estrogen receptor (ER)-α and ER-β), hypoxia-inducible factor (HIF)-1α, transforming growth factor-β1 (TGF-β1), type I TGF-β receptor (TGF-βRI), Smad3, phosphorylation-Smad3 (p-Smad3), epithelial-mesenchymal transition (EMT) markers (E-cadherin, collagen-I, fibronectin and α-SMA) and microRNA (miR)-133a/b were analyzed by immunohistochemistry assay, western blot and/or quantitative RT-PCR. It was observed that EGCG attenuated the prostatic oxidative stress and inflammatory microenvironment, ameliorated prostatic hyperplasia and collagen deposition, reduced the levels of angiogenesis related growth factors, inhibited the over-expression of AR, ER-α, HIF-1α, TGF-β1, TGF-βRI and p-Smad3, enhanced the expression of ER-β, increased the levels of miR-133a/b, as well as relieved prostatic EMT in rats. Both HIF-1α inhibitor and EGCG decreased the expression of HIF-1α and TGF-β1, as well as attenuated EMT in BPH-1 cells. It indicated that EGCG could attenuate testosterone-induced BPH and fibrosis.

Abstract
INTRODUCTION We evaluated the association between serum sex hormone levels and prostate volume in Taiwanese men. METHODS A cross-sectional study was conducted in 505 men (aged 40-79 years, mean age 58 years). Serum total testosterone (TT), free testosterone (FT), dihydrotestosterone (DHT) and estradiol (E2) levels were measured. Total prostate volume (TPV) and transition zone volume (TZV) were measured by transrectal ultrasonography. Body mass index (BMI), DHT/TT and E2/TT were calculated. Correlations were determined using univariate and multivariate regression analyses. RESULTS Apart from DHT, an age-dependent change of sex hormone levels were observed. On univariate analyses, age, BMI, serum DHT level and DHT/TT ratio, as well as serum E2 level and E2/TT ratio, but not serum TT and FT levels showed a significant association with prostate volume. On multivariate analysis, however, only serum DHT level and DHT/TT ratio remained significant. Logistic regression analysis showed that the odds ratios (95% confidence interval) of the second, third, and fourth quartiles of serum DHT levels for benign prostatic hyperplasia (defined as TPV ≥ 20 ml) risk were 2.06 (1.21-3.51), 2.66(1.56-4.53) and 7.15(4.0-12.6), respectively (p < 0.001). CONCLUSIONS Higher serum DHT level and DHT/TT ratio were associated with larger prostate volume and higher prevalence of BPH in Taiwanese men.

Abstract
Epilobium species (Onagraceae) are commonly used herbal remedies in traditional, adjuvant therapy of benignus prostate hyperplasia (BPH), however the pharmacological and clinical standardization of commercially available Epilobii herba (willow-herb) remains difficult. Willow-herb products usually consist of mixtures from various species, with different phenoloid content, often only partially identified. The present study reports comprehensive LC-MS/MS investigation on the polyphenol composition of the most common Epilobium species, emphasizing the pharmaceutical importance of a uniform standardization protocol in case of their products. The antioxidant capacity of species was evaluated by a simple spectrophotometric method, using ABTS(+) (2,2'azinobis-(3-ethylbenzthiazoline-6-sulfonic acid)). High ratio of macrocyclic tannins, mainly oenothein B was identified in all Epilobium species examined. Flavonoid composition of Epilobium extracts showed several differences, especially comparing E. angustifolium to other species. Myricetin, quercetin, kaempferol and their various glycosides were dominant in samples, but their combination and ratio were distinctive in all cases. Epilobium extracts showed high radical-scavenger activity, comparable to that of well-known antioxidants, Trolox and ascorbic acid. Among species examined, extract of Epilobium parviflorum possessed the highest antioxidant capacity (EC(50)=1.71+/-0.05 microg/ml).

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) develops in elderly males when serum androgens are relatively lower than in healthy younger males, but it is not well understood whether and how sex steroids are altered in prostatic hyperplasia. It is also uncertain whether there is any change in sex steroid levels in males older than 40 years of age. The use of androgens in elderly males is often discouraged because of the probable worsening effect of androgens on prostatism. This study aimed to determine the relationship between prostatic hyperplasia and sex steroid levels and whether there is any significant change in these hormones after the age of 40 years. SUBJECTS AND METHODS We studied healthy males of age >or=40 years with (n=92) or without (n=93) clinical prostatic hyperplasia. Serum testosterone, estradiol, gonadotrophins and sex hormone-binding globulin (SHBG) were compared. The hormones and SHBG were also correlated with age. RESULTS No significant difference was found in any hormone in cases with prostatic hyperplasia as compared with the controls. There was no significant age-related change in any hormone except estradiol where as a negative correlation (P<.003) with age was found. CONCLUSIONS Serum sex steroids and SHBG remained unchanged in symptomatic prostatic hyperplasia and except for estradiol there was no significant age-related change in serum testosterone, gonadotrophins and SHBG in healthy males after the fourth decade. More studies are needed to confirm the age-related decline of estrogens in males.
