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.

Refining the Mouse Subtotal Nephrectomy in Male 129S2/SV Mice for Consistent Modeling of Progressive Kidney Disease With Renal Inflammation and Cardiac Dysfunction. Front Physiol 2019; 10:1365.

Abstract
Chronic kidney disease (CKD) is prevalent worldwide and is associated with significant co-morbidities including cardiovascular disease (CVD). Traditionally, the subtotal nephrectomy (remnant kidney) experimental model has been performed in rats to model progressive renal disease. The model experimentally mimics CKD by reducing nephron number, resulting in renal insufficiency. Presently, there is a lack of translation of pre-clinical findings into successful clinical results. The pre-clinical nephrology field would benefit from reproducible progressive renal disease models in mice in order to avail of more widely available transgenics and experimental tools to dissect mechanisms of disease. Here we evaluate if a simplified single step subtotal nephrectomy (STNx) model performed in the 129S2/SV mouse can recapitulate the renal and cardiac changes observed in patients with CKD in a reproducible and robust way. The single step STNx surgery was well-tolerated and resulted in clinically relevant outcomes including hypertension, increased urinary albumin:creatinine ratio, and significantly increased serum creatinine, phosphate and urea. STNx mice developed significant left ventricular hypertrophy without reduced ejection fraction or cardiac fibrosis. Analysis of intra-renal inflammation revealed persistent recruitment of Ly6Chi monocytes transitioning to pro-fibrotic inflammatory macrophages in STNx kidneys. Unlike 129S2/SV mice, C57BL/6 mice exhibited renal fibrosis without proteinuria, renal dysfunction, or cardiac pathology. Therefore, the 129S2/SV genetic background is susceptible to induction of progressive proteinuric renal disease and cardiac hypertrophy using our refined, single-step flank STNx method. This reproducible model could be used to study the systemic pathophysiological changes induced by CKD in the kidney and the heart, intra-renal inflammation and for testing new therapies for CKD.

Int Immunopharmacol 2018; 64:162-169. [PMID: 30179845 DOI: 10.1016/j.intimp.2018.08.038] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Revised: 08/15/2018] [Accepted: 08/26/2018] [Indexed: 12/15/2022]
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.

Antioxidants (Basel) 2017; 6:antiox6040087. [PMID: 29113120 PMCID: PMC5745497 DOI: 10.3390/antiox6040087] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2017] [Revised: 10/25/2017] [Accepted: 10/31/2017] [Indexed: 02/07/2023] Open
Abstract
Pelvic radiation for cancer therapy can damage a variety of normal tissues. In this study, we demonstrate that radiation causes acute changes to pelvic fibroblasts such as the transformation to myofibroblasts and the induction of senescence, which persist months after radiation. The addition of the manganese porphyrin, MnTE-2-PyP, resulted in protection of these acute changes in fibroblasts and this protection persisted months following radiation exposure. Specifically, at two months post-radiation, MnTE-2-PyP inhibited the number of α-smooth muscle actin positive fibroblasts induced by radiation and at six months post-radiation, MnTE-2-PyP significantly reduced collagen deposition (fibrosis) in the skin and bladder tissues of irradiated mice. Radiation also resulted in changes to T cells. At two months post-radiation, there was a reduction of Th1-producing splenocytes, which resulted in reduced Th1:Th2 ratios. MnTE-2-PyP maintained Th1:Th2 ratios similar to unirradiated mice. At six months post-radiation, increased T cells were observed in the adipose tissues. MnTE-2-PyP treatment inhibited this increase. Thus, MnTE-2-PyP treatment maintains normal fibroblast function and T cell immunity months after radiation exposure. We believe that one of the reasons MnTE-2-PyP is a potent radioprotector is due to its protection of multiple cell types from radiation damage.
