After simulated treatments, participants in the Sham Arm were converted to active LiSWT, while participants initially in the Active Treatment Arm received no further treatment. Assessments were performed at baseline and two follow-up visits. Subjective parameters of erectile function (EF) were assessed by total and EF domain scores of the International Index of Erectile Function (IIEF) and sexual encounter profile (SEP). Objective parameters of penile erection were measurements of hypoechoic areas in images obtained by grayscale ultrasound (GUS) with high resolution 15.4 MHz probe and cavernosal artery peak systolic velocity (PSV) and end diastolic velocity (EDV) by color duplex Doppler ultrasound (DUS).

The expression of lncRNA ENST00000510619 was shown to be down-regulated by psoralen in a concentration-dependent manner. CCK-8 assay, wound healing, and transwell assay showed that both psoralen and si-lncRNA ENST00000510619 transfection significantly inhibited the activity, invasion, and migration of PC3 cells (P<0.01 for all).</p><p><strong>Conclusions: </strong>Psoralen was confirmed to inhibit proliferation and block the cell cycle in PC3 cells in this <i>in vitro</i> study. The molecular mechanism involves multiple differentially expressed lncRNAs and mRNAs and is related to the down-regulation of lncRNA ENST000000510619 expression. This study provides the experimental basis for the development of psoralen as a novel anti-CRPC drug and for the consideration of lncRNA ENST00000510619 as a potential clinical target for CRPC.</p>","PeriodicalId":23270,"journal":{"name":"Translational andrology and urology","volume":"13 10","pages":"2294-2306"},"PeriodicalIF":1.9,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11535728/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142591538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
