[PMID: 38979434 PMCID: PMC11228079 DOI: 10.2147/jir.s458132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 06/18/2024] [Indexed: 07/10/2024] Open
Abstract
Introduction Although sertraline has been widely used for chronic prostatitis (CP), the mechanisms are unclear. Herein, we explored the mechanisms of sertraline in treating CP. Methods Network pharmacology methods were used to explore the potential targets and molecular mechanisms. LPS was used to stimulate RWPE-1 cells to construct an in vitro model of CP. An experimental autoimmune prostatitis (EAP) mice model was built. CCK-8 assay, EdU assay, BrdU detection, and Tunel assay were performed to evaluate the proliferation and apoptosis process of cells or tissues, respectively. DCFH-DA and Fluo-4 fluorescence probes were used to detect intracellular ROS and calcium concentrations. Von Frey filaments and open-field tests were utilized to evaluate pain response and depressive-like behavior of mice. Histopathology was evaluated through hematoxylin and eosin staining. RT-qPCR, Western blot, immunofluorescence, and immunohistochemistry were utilized to evaluate the transcription, expression, and location of related proteins. Molecular dynamics (MD) simulation and surface plasmon resonance (SPR) assay were performed to measure the binding capacity of sertraline and related proteins. Results Through a network pharmacology analysis, 27 potential targets of sertraline for CP were obtained, and 5 key targets (CHRM1, ADRA1B, HTR2B, HTR2A, and TRPV1) were finally identified. Functional experiments suggested that TRPV1 was involved in the proliferation, apoptosis inhibition, and ROS production of LPS-induced RWPE-1 cells. In vitro experiments showed that sertraline significantly inhibited cell proliferation, ROS generation, and transcription of inflammation cytokines of LPS-induced RWPE-1 cells. Additionally, sertraline markedly promoted the apoptosis level of LPS-stimulated RWPE-1 cells and elevated the expression level of BAX while reducing the expression levels of Bcl2 and Caspase-3. MD simulation and SPR assay confirmed the direct binding of sertraline to TRPV1. Moreover, sertraline significantly down-regulated the expression level of TRPV1 and inhibited calcium influx of LPS-induced RWPE-1 cells. TRPV1 agonist (Capsaicin) significantly restored the effects on proliferation, apoptosis, ROS production, and calcium influx of sertraline on LPS-induced RWPE-1 cells. Mice experiments demonstrated that sertraline treatment could reduce pain response, improve depression-like symptoms, and relieve local prostate inflammation of EAP mice, as well as down-regulated the expression level of TRPV1, inhibit the proliferation, and promote apoptosis of prostate tissues in EAP mice. Discussion The results revealed the anti-inflammatory effect of sertraline for RWPE-1 cells and EAP mice, and the potential mechanism was regulating the TRPV1 channel. It indicated that sertraline might serve as a complementary anti-inflammatory agent for CP.

Liao WC, Cheng WM, Fan YH, Liou YJ. Impact of type D personality and depressive symptoms on premature ejaculation in young adult males. Sex Med 2023; 11:qfad055. [PMID: 38028734 PMCID: PMC10661336 DOI: 10.1093/sexmed/qfad055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 09/08/2023] [Accepted: 09/29/2023] [Indexed: 12/01/2023] Open
Abstract
Background Premature ejaculation (PE) is one of the most common male sexual dysfunctions with prominent psychological consequences. Type D personality (TDP) is also associated with multiple psychological disorders, such as depression and anxiety. However, the correlation between PE and TDP remains unknown. Aim The study sought to investigate the relationships between depressive symptoms, TDP, and PE. Methods Adult males in Taiwan who were 20 to 40 years of age and who had sexual intercourse in the past 6 months were recruited to complete online questionnaires composed of general demographics, the Premature Ejaculation Diagnostic Tool (PEDT), 5-item International Index of Erectile Function (IIEF-5), Type D Scale-14, and Depression and Somatic Symptom Scale (DSSS). Chi-square test and independent Student's t test were used to compare the parameters between the TDP and non-TDP groups. Univariate and multivariate logistic regression analyses were conducted to evaluate factors related to PE. Outcomes Outcomes were the prevalence of PE and TDP in young Taiwanese men, the associations between depressive symptoms and PE and TDP, and the predictive factors of PE. Results In total, 2558 men with a mean age of 31.3 ± 5.3 years were included in the present study. Among them, 315 (12.3%) and 767 (30.1%) participants were classified as having PE and moderate-to-severe erectile dysfunction (ED), respectively. In total, 1249 (48.8%) participants met the criteria for TDP. The PEDT, IIEF-5, and DSSS, including the total scores and depression and somatic subscales, were significantly higher in men with TDP (all P < .001). PE prevalence was significantly greater in men with TDP than in those without TDP (16.2% vs 8.6%; P < .001). Most parameters, including age, moderate-to-severe ED, the Type D Scale-14 subscales, and the DSSS somatic and depressive subscales, were significantly associated with PE in the univariate analysis. Only the depressive subscale of the DSSS and moderate-to-severe ED (IIEF-5 ≤16) were the independent predictors of PE in the multivariate analysis. Clinical Implications The results suggest that it is important to consider the psychological effects of PE in young men, and the study has provided a biopsychosocial aspect to manage patients with PE. Strengths and Limitations This is the first study to evaluate the association between PE, TDP, and depression in a large population of young adult males. However, the cross-sectional design may have limited the investigation of causality, and selection bias may be present. Conclusion Men with TDP tended to have higher PEDT scores and a prevalence of PE and ED. Moderate-to-severe ED and depressive symptoms are the independent predictive factors of PE.

Song Z, Jin C, Bian Z, Liang C. Radial Extracorporeal Shock Wave Therapy Combined with Resveratrol Derivative Alleviates Chronic Nonbacterial Prostatitis in Rats. Inflammation 2023; 46:584-597. [PMID: 36434437 DOI: 10.1007/s10753-022-01757-3] [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: 04/06/2022] [Revised: 06/21/2022] [Accepted: 10/12/2022] [Indexed: 11/27/2022]
Abstract
Resveratrol (Res) is a non-flavonoid polyphenol compound with biological pleiotropic properties, but low bioavailability limits its application value. Here, we synthesized a new Res derivative ((E)-5-(dimethylamino)-2-(4-methoxystyryl)phenol), and attempted to determine the function of Res derivative combined with radial extracorporeal shock wave therapy (rESWT) in chronic nonbacterial prostatitis (CNP). CNP model rats were constructed by subcutaneous administration of prostatein suspension (15 mg/ml), followed by rESWT treatment alone or in associated with Res or Res derivatives. In this study, inflammatory cell infiltration and tissue fibrosis in the prostate tissues of CNP rats were significantly deteriorated, which was effectively abolished by rESWT treatment alone or in combination with Res or Res derivative. The expression of interleukin 1β (IL-1β), tumor necrosis factor-α (TNF-α), nerve growth factor (NGF), and nuclear factor kappa-B (NF-κB) were increased, while silent information regulator 1 (SIRT1) expression was suppressed in the prostate tissues of CNP rats, which were then rescued by rESWT treatment alone or in associated with Res or Res derivative. Importantly, compared with Res derivative treatment alone or rESWT combined with Res treatment, combination treatment with rESWT and Res derivative was more effective in alleviating inflammation and fibrosis, in reducing IL-1β, TNF-α, NGF, and SIRT1 expression, and in facilitating SIRT1 expression. Overall, rESWT combined with Res derivative treatment improved CNP in rat by reducing inflammation and fibrosis, which attributed to regulate the expression of SIRT1 and NF-κB. Thus, this work provides a theoretical basis for rESWT combined with Res derivative in the clinical treatment of CNP.

Front Cell Infect Microbiol 2022; 12:966004. [PMID: 36250064 PMCID: PMC9563248 DOI: 10.3389/fcimb.2022.966004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 08/24/2022] [Indexed: 11/29/2022] Open
Abstract
Background Microbiota play essential roles in the pathogenesis of prostatitis and depression. However, the changes in prostate microbiota have not yet been explored in rats with prostatitis/depression. This study aimed to investigate the changes of prostate microbiota in rats with prostatitis/depression. Methods Rats with experimental autoimmune prostatitis (EAP) complicated with depression were constructed through injection of rat prostate antigen with immunoadjuvants followed by application of chronic unpredictable mild stress (CUMS). The rats were subjected to inflammatory factor detection and behavioral testing to confirm the establishment of the model. Subsequently, the prostate microbiota was assayed in the rats and compared by 16S rRNA gene sequencing. Results A rat model of EAP complicated with depression was established and confirmed by increases in IL-1β, IL-6, and TNF-α as well as the occurrence of depressive‐like behaviors. EAP/CUMS significantly altered the richness, evenness, and composition of prostate microbiota. Forty-six taxonomic biomarkers for prostate microbiota were enriched in rats with EAP/depression and exhibited statistically significant and biologically consistent differences. Metabolomics profiling revealed that EAP/depression was associated with reductive acetyl coenzyme A pathway, L-lysine fermentation to acetate and butanoate, protein N-glycosylation and purine nucleobases degradation I, which is regulated by DCE29, Nocardioes, Helicobacter and Dorea. Conclusion Findings from the study demonstrate the existence of abnormal prostate microbiota in EAP complicated with depression and may be helpful in the treatment of comorbid diseases of prostatitis and depression.
