Abstract
Introduction Chronic Pelvic Pain Syndrome or Chronic Prostatitis (CPPS/CP) is the most prevalent urologic affliction among young adult men. It is a challenging condition to treat, which significantly decreases patient quality of life, mostly because of its still uncertain aetiology. In that regard, an autoimmune origin is a prominent supported theory. Indeed, studies in patients and in rodent models of Experimental Autoimmune Prostatitis (EAP) have provided compelling evidence suggesting a key role of CD4 Th1 cells in disease pathogenesis. However, the implication of other prominent effectors of the immune system, such as CD8 T cells, has yet to be studied. Methods We herein analyzed the induction of prostatitis and the development of chronic pelvic pain in EAP using CD8 T cell-deficient animals. Results We found similarly elevated PA-specific immune responses, with high frequencies of specific IFNg+CD4+ and IL17+CD4+ T cells in prostate draining lymph nodes from PA-immunized either CD8 KO or wild type animals with respect to controls. Moreover, these peripheral immune responses were paralleled by the development of significant chronic pelvic pain, and accompanied by prostate histological lesions, characterized by hemorrhage, epithelial cell desquamation, marked periglandular leukocyte infiltration, and increased collagen deposition in both, PA-immunized CD8 KO and wild type animals. As expected, control animals did not develop prostate histological lesions. Discussion Our results indicate that CD8 T cells do not play a major role in EAP pathogenesis and chronic pelvic pain development. Moreover, our results corroborate the previous notion that a CD4 Th1 associated immune response drives the induction of prostate tissue inflammation and the development of chronic pelvic pain.

Dual deficiency of melatonin and dihydrotestosterone promotes stromal cell damage and mediates prostatitis via the cGAS-STING pathway in sleep-deprived mice. Cell Commun Signal 2024; 22:183. [PMID: 38491517 PMCID: PMC10941623 DOI: 10.1186/s12964-024-01554-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 03/02/2024] [Indexed: 03/18/2024] Open
Abstract
PURPOSE Prostatitis is a highly prevalent condition that seriously affects men's physical and mental health. Although epidemiological investigations have provided evidence of a correlation between insufficient sleep and prostatitis, the pathogenesis of prostatitis remains unclear. We sought to identify the underlying mechanism involved and identify a promising therapeutic target. METHODS Sleep deprivation (SD) was utilized to establish a mouse model of insufficient sleep in a special device. Prostatitis was observed at different time points post-SD. The degree of prostatitis was evaluated by pathological section and behavioural tests. Using immunofluorescence, western blot, and proteomic analyses, the underlying mechanism of SD-related prostatitis was investigated, and the development and therapeutic target of prostatitis were elucidated. RESULTS SD, as an initial pathological trigger, resulted in a reduction in dihydrotestosterone and melatonin levels. Proteomic analysis revealed that the cGAS-STING pathway may play a significant role in inducing prostatitis. The subsequent results illustrated that the dual reduction in dihydrotestosterone and melatonin led to an accumulation of reactive oxygen species and the release of mitochondrial DNA (mt-DNA). The accumulation of mt-DNA activated the cGAS-STING pathway, which recruited inflammatory cells into the prostatic stroma through the secretion of interferon-β. Consequently, an inflammatory microenvironment was formed, ultimately promoting the development of prostatitis. Notably, mice with SD-induced prostatitis gradually recovered to a normal state within 7 days of recovery sleep. However, after being subjected to SD again, these mice tended to have a more pronounced manifestation of prostatitis within a shorter timeframe, which suggested that prostatitis is prone to relapse. CONCLUSIONS The cGAS-STING pathway activated by dual deficiency of dihydrotestosterone and melatonin plays a comprehensive inflammatory role in SD-related prostatitis. This research provides valuable insights into the pathogenesis, therapeutic targets, and prevention strategies of prostatitis.

Abstract
BACKGROUND Chronic pelvic pain syndrome (CPPS) is a typical symptom of chronic prostatitis (CP) in males that may cause abnormal urination, sexual dysfunction, or depression and significantly affect the quality of life of the patient. Currently, there is no effective treatment for CPPS due to its recurrence and intractability. For synergistic CPPS therapy, we developed pH/reactive oxygen species (ROS) dual-responsive dexamethasone (Dex) nanoformulations using a ROS-responsive moiety and phytochemical modified α-cyclodextrin (α-CD) as the carrier. RESULTS Dex release from the nanoformulations can be controlled in acidic and/or ROS-rich microenvironments. The fabricated Dex nanoformulations can also be efficiently internalized by lipopolysaccharide (LPS)-stimulated macrophages, prostatic epithelial cells, and stromal cells. Moreover, the levels of proinflammatory factors (e.g., TNF-α, IL-1β, and IL-17 A) in these cells were significantly decreased by Dex nanoformulations treatment through the release of Dex, phytochemical and elimination of ROS. In vivo experiments demonstrated notable accumulation of the Dex nanoformulations in prostate tissue to alleviate the symptoms of CPPS through the downregulation of proinflammatory factors. Interestingly, depression in mice may be relieved due to alleviation of their pelvic pain. CONCLUSION We fabricated Dex nanoformulations for the effective management of CPPS and alleviation of depression in mice.

Traditional Chinese Medicine Danzhi qing'e decoction inhibits inflammation-associated prostatic hyperplasia via inactivation of ERK1/2 signal pathway. JOURNAL OF ETHNOPHARMACOLOGY 2023; 309:116354. [PMID: 36906158 DOI: 10.1016/j.jep.2023.116354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 02/28/2023] [Accepted: 03/02/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inflammation plays a critical role during benign prostatic hyperplasia (BPH) development. Danzhi qing'e (DZQE) decoction is a traditional Chinese medicine that has been widely used for estrogen and androgen-related diseases. However, its effect on inflammation-related BPH remains unclear. AIM OF THE STUDY To investigate the effect of DZQE on inhibition of inflammation-related BPH, and further identify the possible mechanism involved. METHODS AND MATERIALS Experimental autoimmune prostatitis (EAP)-induced BPH was established and then 2.7 g/kg of DZQE was administrated orally for 4 weeks. The prostate sizes, weights and prostate index (PI) values were recorded. Hematoxylin and eosin (H&E) was performed for pathological analyses. Macrophage infiltrate was evaluated by Immunohistochemical (IHC). The inflammatory cytokine levels were measured by Rt-PCR and ELISA methods. The phosphorylation of ERK1/2 was examined by Western blot. The expression differences of mRNA expressions between EAP-induced and oestrogen/testosterone (E2/T)-induced BPH was investigated by RNA sequencing analyses. In vitro, human prostatic epithelial BPH-1 cells were stimulated with the conditioned medium from monocyte THP-1-derived M2 macrophages (M2CM), followed by treatment of Tanshinone IIA (Tan IIA), Bakuchiol (Ba), ERK1/2 antagonist PD98059 or ERK1/2 agonist C6-Ceramide. The ERK1/2 phosphorylation and cell proliferation were then detected by Western blotting and CCK8 assay. RESULTS DZQE significantly inhibited the prostate enlargement and decreased PI value in EAP rats. Pathological analysis showed that DZQE alleviated prostate acinar epithelial cell proliferation by decreasing and reduction of CD68+ and CD206+ macrophage infiltration in the prostate. The levels of cytokines TNF-α, IL-1β, IL-17, MCP-1, TGF-β, and IgG in EAP rats' prostate or serum were significantly suppressed by DZQE as well. Moreover, mRNA sequencing data showed that the expressions of inflammation-related genes were elevated in EAP-induced BPH but not in E2/T-induced BPH. ERK1/2-related genes expression has been found in both E2/T and EAP-induced BPH. ERK1/2 is one of the core signal pathways involved in EAP-induced BPH, which was activated in EAP group but inactivated in DZQE group. In vitro, two active components of DZQE Tan IIA and Ba inhibited M2CM-induced BPH-1 cell proliferation, similarly to ERK1/2 inhibitor PD98059 did. Meanwhile, Tan IIA and Ba inhibited M2CM-induced ERK1/2 signal activation in BPH-1 cells. When re-activated the ERK1/2 by its activator C6-Ceramide, the inhibitory effects of Tan IIA and Ba on BPH-1 cell proliferation were blocked. CONCLUSION DZQE suppressed inflammation-associated BPH via regulation of ERK1/2 signal by Tan IIA and Ba.

Abstract
Purpose We aim to explore expression profiles of genes in SCDH of CPPS model rat relevant to pain and inflammation by RNA-Seq and to investigate the mechanism of anti-inflammatory and analgesic of EA. Methods Thirty-six SD male rats were randomly divided into three groups (n = 12): sham operation, model, and EA. The rat CPPS model was established by injecting CFA into the ventral lobes of the prostate. The rats in EA group were treated at Guanyuan (CV4), Zhongji (CV3), Sanyinjiao (SP6) and Huiyang (BL35) for a total of 20 times, with a frequency of 2/100Hz. Mechanical allodynia, H&E staining and ELISA were used to detect the changes of pain threshold and tissue inflammation; RNA-Seq technique was used for profiling gene changes in SCDH and qRT-PCR was used for further validation. Results Persistent mechanical allodynia and severe tissue inflammatory reaction both occurred in CPPS rats. After EA therapy, the pain sensitivity and inflammatory response of CPPS rats decreased significantly. RNA-Seq identified that a total of 46 DEGs were significantly up-regulated and 65 DEGs down-regulated after EA. GO enrichment showed that EA was mainly reflected in the regulation of the immune system by participating in the regulation of leukocyte, neutrophil cellular processes and cytokine metabolism. KEGG enrichment demonstrated that signal transduction and immune system were the most significant pathways. We further identified that the expressions of Pik3r2, Akt1, and Casp9 were significantly up-regulated and Jak2 and Stat3 down-regulated in the PI3K-AKT/JAK-STAT signal pathway. Conclusion Our study revealed that immune and inflammatory responses are the main biological events that induce chronic pelvic pain in rats, and EA can exert anti-inflammatory and analgesic effects by regulating the expression of related genes on PI3K-AKT/JAK-STAT signal pathway in SCDH. This study provided putative novel targets of EA, which may have anti-inflammatory and analgesic effects of CPPS.

Abstract
OBJECTIVES However, the pathogenesis and etiology of CP/CPPS are still poorly understood. Therefore, there is a need for further research through the Image J software to develop models capable of imitating the pathogenesis and etiology of CP/CPPS with different doses of the pathogenesis and the etiology of CP/CPPS is still poorly understood. The aim was to determine the area of the prostatic interstitium, the localization of the inflammation, and the impact of different doses on the group model. MATERIALS AND METHODS A total of 30 male ICR mice were randomly grouped into 5 (n = 6): 45 μg group = 6, 60 μg group = 6, 90 μg group = 6, 120 μg group = 6, 120 μg group = 6, control group = 6. With the exception of the control group, all the groups were immunized by injecting 0.2 mL of T2 peptide emulsion and immune adjuvant CFA to induce non-bacterial chronic prostatitis on days 0 and 14 of the mice and finally executed on day 28. All injections were administered subcutaneously. HE staining was used to evaluate changes in prostate pathology. Image J was used to calculate the area of the prostate interstitium, which represents the degree of prostate edema. To compare statistical differences between groups, the ANOVA test was used. RESULTS From the perspective of pathological scoring, the 60 μg, 90 μg, and 120 μg groups had the highest scores using Image J to treat inflammatory cells. In addition, in the prostate interstitium area treated, it was found that the 90 μg group attained the largest prostate interstitial area as well as the highest degree of swelling. CONCLUSIONS From the results, Image J software is an effective tool in the calculating the surface of the prostatic interstitium and the specific localization of the inflammation.

Jiedu Huoxue decoction improves chronic abacterial prostatitis/chronic pelvic pain syndrome through activating Wnt/GSKβ/β-catenin signaling pathway and alleviating apoptosis. Pharmacotherapy 2022; 149:112830. [PMID: 35306428 DOI: 10.1016/j.biopha.2022.112830] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 03/12/2022] [Accepted: 03/14/2022] [Indexed: 01/02/2023]
Abstract
BACKGROUND Chronic abacterial prostatitis/chronic pelvic pain syndrome (CP/CPPS) accounts for 90% of clinical prostatitis, and there is no specific and effective treatment for it. Jiedu Huoxue decoction (JDHXD) has been believed to be an effective agent for CP/CPPS, but the specific mechanism remains unclear. METHODS Carrageenan and LPS were used to established the animal and cell models of CP/CPPS, respectively. The prostate index, urine volume, lumen area, epithelial thickness, and pain response time were investigated. TUNEL staining and flow cytometry were applied to measure apoptosis levels in vivo and in vitro. RESULTS JDHXD improved CP/CPPS recovery in a dose-dependent manner. JDHXD restrained apoptosis and activated Wnt/GSK-3β/β-catenin signaling pathway in the CP/CPPS animal model. Inhibition of Wnt/GSK-3β/β-catenin signaling pathway remarkably aggravated apoptosis and suppressed the improvement of CP/CPPS by JDHXD. XAX939 markedly reversed the suppression of cell apoptosis and ROS level caused by JDHXD in vitro. CONCLUSION Jiedu Huoxue decoction improved CP/CPPS through activating Wnt/GSKβ/β-catenin signaling pathway and inhibiting apoptosis. This study might provide a novel insight for the prevention and treatment of CP/CPPS through activating Wnt/GSK-3β/β-catenin signaling pathway.

Abstract
BACKGROUND Prostatitis is the third most common urologic condition affecting more than half the male population at some point in their lives. There are different categories of prostatitis, of which approximately 90% of cases can be classified under the National Institute of Health (NIH) type III category (chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)) with no causative agents identified. CP/CPPS is associated with several symptoms, of which the most prominent being chronic pain. Despite its high incidence, pain management in patients with CP/CPPS has been poor, possibly due to the lack of understanding of aetiological factors and mechanisms underlying pain development. METHODS An extensive literature search of published articles on the molecular mechanisms of pain in CP/CPPS was conducted using PubMed and Google Scholar search engines (https://pubmed.ncbi.nlm.nih.gov and https://scholar.google.com). The terms used for the search were: prostatitis, pain mechanism in CP/CPPS, prostatitis pain models, acid-sensing ion channels (ASICs), transient receptor potential vanilloid type 1 (TRPVs), purinergic channels (P2X) in prostatitis pain mechanism and inflammatory mediators in CP/CPPS. The papers were identified based on the title and abstract, and after excluding the articles that did not emphasize the pain mechanism in CP/CPPS. Ninety-five articles (36 review and 59 original research papers) met our criteria and were included in the review. RESULTS A number of inflammatory mediator molecules and pain channels, including ASICs, transient receptor potential vanilloid channels (TRPVs) and P2Xs have been investigated for their role in prostatitis pain pathology using various animal models. CONCLUSION This review summarizes the pain mechanisms in CP/CPPS focusing on the inflammatory mediators, neurotransmitters, pain-transducing ion channels and small animal models developed for studying prostatitis.

Abstract
Chronic non-bacterial prostatitis (CNP) is one of the most prevalent diseases in human males worldwide. In 2005, the prostate-gut axis was first proposed to indicate the close relationship between the prostate and the intestine. This study investigated CNP-induced changes of the gut microbiota, gene expression and DNA methylation in a rat model by using multi-omics analysis. Firstly, 16S rDNA sequencing presented an altered structure of the microbiota in cecum of CNP rats. Then, transcriptomic analysis revealed that the expression of 185 genes in intestinal epithelium was significantly changed by CNP. These changes can participate in the immune system, digestive system, metabolic process, etc. Finally, methylC-capture sequencing (MCC-Seq) found 73,232 differentially methylated sites (DMSs) in the DNA of intestinal epithelium between control and CNP rats. A combined analysis of methylomics and transcriptomics suggested an epigenetic mechanism for CNP-induced differential expression genes correlated with intestinal barrier function, immunity, metabolism, enteric infectious disease, etc. More importantly, the transcriptomic, methylomic and gut microbial changes were highly correlated with multiple processes including intestinal immunity, metabolism and epithelial barrier function. In this study, disrupted homeostasis in the gut microbiota, gene expression and DNA methylation were reported in CNP, which supports the existence of the gut-prostate axis.

Abstract
The assessment and management of urologic chronic pelvic pain syndrome (UCPPS), is controversial. It is classified by voiding symptoms, pelvic pain, and bladder pain, which is weekly treated, weekly understood, and bothersome. In the aspect of clinical efforts and research to help people with this syndrome have been hampered by the deficiency of a widely reliable, accepted, and a valuable tool to evaluate the patient symptoms and quality of life (QoL) impact. However, the etiology comes into sight is multifactorial, and available treatment options have been imprecise considerably in present years. We compiled the published literature on the assessment of the syndrome, a tentative role of pharmacological and non-pharmacological (conservative, alternative, and invasive therapy) interventions in eradicating the disease as well as improving symptoms. The previously published literature on animal models has established the association of immune systems in the etiology, pathogenesis, and progression of the disease. The UPOINT system for clinical phenotyping of UCPPS patients has six predefined domains that direct multimodal therapy, which would lead to significant symptom improvement in the medical field. The narrative review aims to scrutinize the fluctuating scientist's views on the evaluation of patient and multimodal treatment of the UPOINT system.

Abstract
Purpose Chronic prostatitis (CP) is a common urinary disease characterized by a complex sequence of symptoms including prostatodynia, which results in significant physical pain and mental burden to affected patients. Currently, CP has no standard treatment. Thus, physical therapy electroacupuncture (EA) which has been successful in treating several inflammation-related pain conditions was used to determine its effect on rats with CP. Materials and Methods Rats were castrated and treated with beta-estradiol for 28 days for CP modeling, and EA was initiated one week after. Following three weeks of treatment, pain-related behavioral testing, mechanical withdrawal threshold, and potential histopathological mechanisms were examined. Results EA treatment produced a significant antinociceptive effect, effectively increasing the pain threshold of CP rats, and the biochemical results revealed significantly lowered prostatic specific antigen levels. Histopathological results also demonstrated that EA exerted protective properties on prostate morphological changes, as well as decreased inflammation cytokines and oxidative stress molecular expressions in prostate tissue. Furthermore, EA alleviated microglial and astrocyte activation in the dorsal horn of the spinal cord, decreasing CXC motif ligand 1 expressions in activated spinal astrocytes. Conclusion In conclusion, it was demonstrated that EA alleviated CP-induced pain, which was partly achieved by the downregulation of inflammation, oxidative stress, and spinal cord glial activation.

Abstract
BACKGROUND Prostate Cancer (PCa) is defined as a major health problem faced by the male population. AIM We aimed to investigate the protective effects of Orange Peel Extract (OPE) and/or Selenium (Se) on chronic non-bacterial prostatitis in a rat model. METHODS Fifty-six adult male Wistar albino rats were castrated; after 5 days, they were divided randomly into eight groups (n= 7). The control group received saline treatment; while 17β-estradiol (E2) (0.25mg/kg) was injected subcutaneously in rats from Groups V, VI, VII, and VIII to induce chronic non-bacterial prostatitis. They were then treated with OPE (400mg/kg body weight; Groups II, IV, VI, and VIII) and/or sodium selenite (0.5mg/kg body weight; Groups III, IV, VII, and VIII) for 30 days. Interleukin-2 (IL2) and Prostate Cancer Antigen 3 (PCA3) mRNA expressions were determined using qPCR; Prostate-Specific Antigen (PSA) protein expression was determined immunohistochemically. Prostate tissue histology was examined by hematoxylin and eosin staining, and the levels of oxidative stress markers and antioxidant enzymes were measured. RESULTS E2 administration significantly increased IL2 and PCA3 mRNA expressions, and PSA protein expression. It also increased the prostate wet weight and body weight, and lipid peroxidation, nitric oxide, TNF-α, and IL-1β levels, decreased the glutathione and antioxidant enzyme levels and caused distinct histological alterations in the prostate gland. OPE and/or Se markedly improved all the studied parameters due to their antioxidant properties and anti-inflammatory effects. CONCLUSION OPE and Se showed protective effects against 17β-estradiol-induced chronic non-bacterial prostatitis. These results suggest that protection of chronic non-bacterial prostatitis by OPE+Se combination involves anti-oxidation and anti-inflammation. Moreover, their synergistic mechanism was mostly achieved via the regulation of oxidative stress and inflammation processes.

Abstract
DNA-nanotechnology-based nano-architecture scaffolds based on circular strands were designed in the form of DNA-nanowires (DNA-NWs) as a polymer of DNA-triangles. Circularizing a scaffold strand (84-NT) was the critical step followed by annealing with various staple strands to make stiff DNA-triangles. Atomic force microcopy (AFM), native polyacrylamide gel electrophoresis (PAGE), UV-analysis, MTT-assay, flow cytometry, and confocal imaging were performed to assess the formulated DNA-NWs and cisplatin (CPT) loading. The AFM and confocal microscopy images revealed a uniform shape and size distribution of the DNA-NWs, with lengths ranging from 2 to 4 μm and diameters ranging from 150 to 300 nm. One sharp band at the top of the lane (500 bp level) with the loss of electrophoretic mobility during the PAGE (native) gel analysis revealed the successful fabrication of DNA-NWs. The loading efficiency of CPT ranged from 66.85% to 97.35%. MTT and flow cytometry results showed biocompatibility of the blank DNA-NWs even at 95% concentration compared with the CPT-loaded DNA-NWs. The CPT-loaded DNA-NWs exhibited enhanced apoptosis (22%) compared to the apoptosis (7%) induced by the blank DNA-NWs. The release of CPT from the DNA-NWs was sustained at < 75% for 6 h in the presence of serum, demonstrating suitability for systemic applications. The IC50 of CPT@DNA-NWs was reduced to 12.8 nM CPT, as compared with the free CPT solution exhibiting an IC50 of 51.2 nM. Confocal imaging revealed the targetability, surface binding, and slow internalization of the DNA-NWs in the scavenger-receptor-rich cancer cell line (HepG2) compared with the control cell line.

Abstract
PURPOSE Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has uncertain etiology and lacks effective treatment. Autoimmunity is an important pathogeny, and experimental autoimmune prostatitis (EAP) models have long been used for studying CP/CPPS. This review presents the detailed current knowledge of EAP models based on evaluation criteria aspects to provide a tool for model selection in pathogenesis studies and therapeutic drug screening. METHODS We extensively searched the published literature on CP/CPPS and different antigen-induced EAP models focusing on the histopathology, clinical-related phenotypes, and biochemical indicators. We also cover the changes in the prostate function and other organs in EAP. Finally, we try to get some insights about antigen-based therapeutic approaches for CP/CPPS. RESULTS Several inciting autoantigens were reported in EAP, including male accessory gland extracts, prostate extracts (PE), prostatic steroid-binding protein, prostatic spermine-binding protein (p25), prostatic acid phosphatase, seminal vesicle secretory protein 2, and T2 peptide. All of these models mimicked histological prostatitis, however only p25- and T2-induced models developed both pelvic pain and voiding behaviors. PE immunization is the most widely used method. Diminished fertility and mental health disorders can be found in PE model. Oral and intravenous T2 peptide have been studied for antigen-specific therapy and achieved preliminary progress in EAP models. CONCLUSIONS PE-induced model is the most commonly used, while T2- or p25-model could serve as a promising CP/CPPS model. Antigen-specific therapy in CP/CPPS deserves further study.

Abstract
Chronic nonbacterial prostatitis (CNP) is a common male disease with high incidence and low cure rate. This study aims to investigate the anti-CNP potential of Poria cocos polysaccharides (PPs) in a λ-carrageenan-induced CNP rat model. Results showed that PPs exerted anti-CNP functions by reducing the prostate weight and prostate index as well as the level of C-reactive protein (CRP) and pro-inflammatory cytokines (TNF-α and IL-1β). Further analysis on sex hormones revealed that PPs could favor CNP alleviation by regulating the production of testosterone (T), dihydrotestosterone (DTH), and estradiol (E2). PPs could also alleviate CNP by regulating the level of inducible nitric oxide synthase (iNOS), malonaldehyde (MDA), and superoxide diamutase (SOD) in inflamed prostate, thereby enhancing the anti-oxidative stress activity. As most non-digestive polysaccharides are fermented by gut microbiota rather than being digested directly by the host, we further analyzed PP-induced changes in gut microbiota. Microbiomic analysis revealed that PPs significantly change the profile of gut microbiota. Moreover, the relative abundance of five genera was recovered by PPs with a dose-effect relationship, thereby being suggested to play critical roles in the alleviation of CNP. Epigenomic (methylomic) analysis showed that PPs remodeled the DNA methylome of intestinal epithelia, by which PPs might modify hormone production. In the present study, we reported the anti-CNP activity of PPs as well as the involved mechanisms.

Abstract
Camptothecin (CMPT) in a free form is extremely cytotoxic as well as hydrophobic drug, and is considered to be highly contagious for systemic administration. The fibronectin (FN)-functionalized DNA-based nanocarrier has been designed to load CMPT and target integrin (αvβ3) receptors which are highly expressed on the A549 cancer cells. Here, we report DNA nanocarrier in the form of DNA-nanofibers (DNA-NFs) capable of loading CMPT via strand intercalation in the GC (base pairs)-rich regions of the DNA duplex. Hence, our keen purpose was to explore the potential of DNA-NFs to load CMPT and assess the improvements of the outcomes in terms of enhanced therapeutic effects to integrin-rich A549 cancer cells with reduced cytotoxic effects to integrin-lacking HEK293 cells. DNA-NFs were formulated as a polymer of DNA triangles. DNA triangles arranged in a programmed way through the complementary overhangs present at the vertices. DNA triangles were primarily obtained through the annealing of the freshly circularized scaffold strands with the three distinct staple strands of specific sequences. The polymerized triangular tiles instead of forming two-dimensional nanosheets underwent self-coiling to give rise to DNA-NF-shaped structures. Flow cytometry and MTT assays were performed to observe cytotoxic and apoptotic effects on integrin-rich A549 cancer cells compared with the integrin-deficient HEK293 cells. AFM, native-page, and confocal experiments confirmed the polymerization of DNA triangles and the morphology of the resulting nanostructures. AFM and confocal images revealed the length of DNA-NFs to be 3-6 μm and the width from 70 to 110 nm. CMPT loading (via strands intercalation) in GC-rich regions of DNA-NFs and the FN functionalization (TAMRA tagged; red fluorescence) via amide chemistry using amino-modified strands of DNA-NFs were confirmed through the UV-shift analysis (> 10 nm shift) and confocal imaging. Blank DNA-NFs were found to be highly biocompatible in 2-640 μM concentrations. MTT assay and flow cytometry experiments revealed that CMPT-loaded DNA-NFs showed a dose-dependent decrease in the cell viability to integrin-rich A549 cancer cells compared with the integrin-deficient HEK293 cells. Conclusively, FN-functionalized, CMPT-loaded DNA-NFs effectively destroyed integrin-rich A549 cancer cells in a targeted manner compared with integrin-deficient HEK293 cells. Grapical abstract.

Influence of Experimental Autoimmune Prostatitis on Sexual Function and the Anti-inflammatory Efficacy of Celecoxib in a Rat Model. Front Immunol 2020; 11:574212. [PMID: 33013933 PMCID: PMC7509491 DOI: 10.3389/fimmu.2020.574212] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Accepted: 08/17/2020] [Indexed: 11/13/2022] Open
Abstract
Experimental autoimmune prostatitis (EAP) is a well-established model induced by an autoimmune response to prostate antigen. The symptomatic, pathological, and immunological characteristics of EAP animals are highly consistent with human chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), which makes EAP an ideal model for this disease. Here, we investigate the influence of EAP on male rat sexual function and the efficacy of anti-inflammatory therapy with celecoxib. EAP rat models were established using male Wistar rats. Rats were randomly assigned to a normal control group, an EAP model group, or an EAP model with celecoxib treatment group (celecoxib group). Behavioral changes, sexual behavioral changes, and erectile function were estimated using an open-field test, a sucrose consumption test, mating experiments, and by intracavernous pressure/mean arterial pressure ratio (ICP/MAP). Histological changes in the prostate were observed by HE staining, and the serum inflammatory factors IL-1β and TNF-α levels were measured by enzyme-linked immunosorbent assay. In addition, serotonin (5-hydroxytryptamine, 5-HT), 5-HT1A receptor, 5-HT2C receptor, and serotonin transporter (SERT) expression levels in the hippocampus and spinal cord (T13–L1, L5–S2) were examined by immunohistochemistry and western blot analysis. Results showed that EAP rats exhibited characteristics of depression, decreased sexual drive, premature ejaculation, and increased threshold of penile erection. Moreover, all these changes were effectively alleviated by celecoxib. Significant increases in prostatic interstitial infiltration by inflammatory cells and in serum IL-1β and TNF-α levels were observed in EAP rats, and these were partially reduced by celecoxib. Additionally, the expression pattern of serotonin system regulators in the hippocampus and spinal cord were altered in EAP model rats, including a decrease in 5-HT levels and an increase in 5-HT1A receptor levels. In conclusion, autoimmune prostatitis impaired rat sexual function, and this was effectively prevented by anti-inflammatory therapy with celecoxib. Moreover, a serotonin system disorder in the central nervous system was likely mediated via inflammation in EAP rats.

Bladder sensation evaluation of a carrageenan-induced chronic prostatitis model using a direct measurement of the bladder mechanosensitive single-unit afferent nerve activity. Neurourol Urodyn 2020; 39:2111-2119. [PMID: 32725829 DOI: 10.1002/nau.24453] [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: 04/14/2020] [Revised: 06/09/2020] [Accepted: 06/30/2020] [Indexed: 11/12/2022]
Abstract
AIMS Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) causes long-standing pain and/or storage symptoms. This study aimed to evaluate the likelihood of deterioration of bladder sensation in a carrageenan-induced CP/CPPS model by direct measurement of the bladder mechanosensitive single-unit afferent nerve activity. METHODS In this study, male adult Sprague-Dawley rats were used. They were injected 50 µL of 3% λ-carrageenan or its vehicle (saline) into both lobes of the ventral prostate. Seven days following injection, the pain behavior at the pelvic-perineal area (using von Frey filaments), prostatic blood flow (using a laser blood flowmeter), and histology were examined along with cystometry (under conscious free-moving condition) and mechanosensitive single-unit afferent nerve activity (under urethane anesthesia). RESULTS The prostate showed increased tissue weight and decreased blood flow and inflammatory cell infiltration in the carrageenan group compared to the control group. Consequently, the threshold of the pain behavior was decreased, and the basal and threshold pressures of the bladder were increased in the carrageenan group. In contrast, no significant differences of bladder histology and other cystometric parameters were found between the groups. Regarding Aδ- or C-fibers, the mechanosensitive afferent nerve activities revealed no differences in either group. CONCLUSIONS The carrageenan-induced CP/CPPS rat model showed edema, ischemia, and inflammatory pain in the prostate, whereas a little change was detected in bladder sensation. These findings, which were evaluated using a direct measurement of the mechanosensitive single-unit afferent nerve activity, suggest that the bladder sensation is unlikely deteriorated in this model.

Abstract
Abstract
Objectives
This study was undertaken to reveal therapeutic effects and the preliminary mechanism of Chinese medicine formula Qianlie Tongli decoction (QTD) in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).
Methods
A total of 50 male C57BL/6 mice were randomly divided into five groups. All groups except the control group were injected subcutaneously T2 peptide emulsion, which induced the CP/CPPS model. After the induction of CP/CPPS, the model group was given normal saline by oral gavage while low-dose, medium-dose and high-dose groups were treated with Chinese medicine formula. Micturition habits and pain behaviour of mice were analysed for each group. Haematoxylin and eosin (H&E) staining was used to investigate prostate inflammation. The serum level of tumour necrosis factor-α (TNF-α) was measured by enzyme-linked immunosorbent assay (ELISA) kit.
Key findings
Chinese medicine formula significantly reduced the number of urine spots and improved pain response frequency in the medium-dose and high-dose group. The high-dose group showed reduced considerably inflammatory lesion and inflammatory cell infiltration than the low-dose and medium-dose groups. Serum levels of TNF-α in the high-dose group were significantly reduced compared with the model group.
Conclusions
The results demonstrated the therapeutic effects of Qianlie Tongli decoction in CP/CPPS mice by analysing clinically relevant symptoms (urinary tract system, pelvic pain and prostate inflammation) and preliminarily explored the inflammatory-related treatment mechanisms by measuring TNF-α.

Abstract
To explore the mechanism of microRNA-155 (miR-155) deficiency, protecting against experimental autoimmune prostatitis (EAP) in a toll-like receptor 4 (TLR4)-dependent manner. After wild-type (WT) and miR-155-/- mice were injected with complete Freund's adjuvant and prostate antigen to establish EAP model, half were randomly selected for injection with lipopolysaccharide (LPS, a TLR4 ligand). The following experiments were then performed: von Frey filaments, hematoxylin-eosin (HE) staining, real time quantitative polymerase chain reaction (qRT-PCR), Western blotting, and enzyme-linked immunosorbent assay (ELISA). And the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and the level of Malondialdehyde (MDA) were detected by corresponding kits.miR-155-/- mice with prostatitis exhibited the attenuated pelvic tactile allodynia/hyperalgesia and the suppressed TLR4/nuclear factor-kappa B (NF-κB) pathway as compared with the WT mice with prostatitis. In addition, LPS enhanced the upregulation of miR-155 and the activation of the TLR4/NF-κB pathway in the prostatic tissues of WT mice with EAP. Furthermore, prostatitis mice had aggravated inflammation scores accompanying the increased interleukin (IL)-1β, tumor necrosis factor-α, IL-6, interferon-γ, IL-12, and MDA in prostatic tissues with the decreased IL-10, SOD and GSH-Px, and the unaltered IL-4. Compared with the mice from the WT + EAP group and the miR-155-/- + EAP + LPS group, mice from the miR-155-/- + EAP group had decreased inflammation and oxidative stress. miR-155 deficiency ameliorated pelvic tactile allodynia/hyperalgesia in EAP mice and improved inflammation and oxidative stress in prostatic tissues in a TLR4-dependent manner involving NF-κB activation, thereby exerting a therapeutic effect in chronic prostatitis treatment.

Abstract
Chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) is commonly diagnosed in men younger than 50 years old. It is characterized by pelvic pain, voiding symptoms and sexual dysfunction. The considerable discomfort or pain experienced has a negative impact on the quality of life of patients and is a huge economic burden because of the high recurrence rate and the low cure rate. Appropriate animal models are essential for the development of new drugs for the treatment of CP/CPPS, and several rodent models induced by different methods and over different time frames have been established. This article reviews studies of three in vivo rodent models of prostatitis, namely, chemical-induced, autoimmune-induced and hormone-associated models reported by us and other investigators. Recent clinical investigation has suggested that tadalafil improves the International Prostatic Symptom Score and the total National Institutes of Health Chronic Prostatitis Symptom Index score of patients with benign prostatic hyperplasia with CP/CPPS, which enables us to investigate the effect of tadalafil on the pelvic-pain-related behavior and prostatic inflammation in two of these prostatitis model types, experimental autoimmune prostatitis (EAP) and hormone/castration-induced prostatitis (HCP). Both models showed the pelvic-pain-related behavior and prostatic inflammation that are characteristic of chronic prostatitis. In EAP, tadalafil suppressed both the pelvic-pain-related behavior and the prostatic inflammation. In HCP, tadalafil suppressed the pelvic-pain-related behavior. These results mimic the clinical findings. Therefore EAP and HCP are suitable for the evaluation of the potency of drugs for the treatment of CP/CPPS.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common clinical syndrome with unknown aetiology. In this study, we used the T2 peptide in C57BL/6 (B6) mice and Sprague Dawley (SD) rats model during different stages. We sought to understand the role of CD4+ T cells and macrophages in CP/CPPS. A total of 16 B6 mice and 18 SD rats were divided into five groups: B6-naïve (n = 6), B6 model (n = 10), SD-naïve (n = 6), SD-45-day model (n = 6) and SD-56-day model (n = 6). The B6 model group was subcutaneously injected with 0.2 ml of (225μg/ml) T2 peptide on 0 and 14th day and was finally sacrificed on 28th day. The SD-45- and SD-56-day model groups were subcutaneously injected with 1ml of (50 μg/ml) T2 peptide on 0 and 14th day and were finally sacrificed on 45th and 56th day respectively. An equivalent volume of normal saline (NS) solution was injected to the naïve groups and analysed the pain and voiding behaviour. We have calculated the prostate index, H&E staining and immunofluorescence of CD4+ T cells and macrophages (CD68) in each group. T2 peptide immunization in B6 mice and SD rats caused severe prostatitis and cell infiltration, mainly composed of CD4+ T cells and macrophages. The SD-56-day model group showed more severe inflammatory cells infiltration than SD-45-day model group. Moreover, inflammatory cells infiltration and red secretions in B6 model were less than SD model. Expression of CD4+ T cells and macrophages was also consistent with H&E results. These results indicated that different stages of CP/CPPS, inflammatory response, and the inflammation of the rat were stronger than the mouse. Our study suggests that CD4+ T cells and macrophages are key factors in the development of CP/CPPS.

Abstract
Poor control towards glycemic levels among diabetic patients may lead to severe micro/ macro-vascular and neuropathic complexities. Proper functioning of alpha-beta cells of pancreases is required to attain long term glycemic control among type 2 diabetics. The recent developments to manage diabetes are focused on controlling the insulin-glucagon secretions from the pancreases. DPP-4 inhibitors class of drugs after elevating GLP-1/GIP (incretins) levels in the blood, not only raise the insulin levels but also suppress the glucagon level. Vildagliptin (VI) is a potent DPP-4 inhibitor with least adverse events compared to other DPP-4 inhibitors. We encapsulated VI into 3D nanocube that gets bind to the DNA due to secondary amine in its chemical structure. DNA-nanocube being negatively charged was incubated with the PLL to attain positive surface. Ultimately VI loaded nanocubes were coated with the negatively charged Na-alginate via electrostatic attraction method to get stable spherical nanospheres for oral delivery of VI. Nanospheres were evaluated physically through native PAGE analysis, DSC, TGA, dissolution testing, XRD and FTIR. We attained uniformed and spherical nanospheres with stable topology, nanoscale size precision (40–150 nm in diameter), Entrapment efficiency (up to 90%), prolonged drug release (13 ± 4 h) at basic pH, and superior oral antidiabetic effects with improved GLP1 and glycemic levels. The formulated nanospheres attained size uniformity and better therapeutic outcomes in terms of reduced adverse events and better control of glycemic levels than previously reported methods with decreased dosage frequency tested in Db/Db mice.
