Erectile dysfunction (ED) is a male sexual dysfunction with a gradually increasing prevalence, and current treatments are ineffective. This study aims to find a safer and more effective treatment for erectile dysfunction. Bone marrow-derived mesenchymal stem cells (BM-MSCs) treated with VEGFA. The expression of endothelial markers vWF, VE-cadherin and eNOS were determined by overexpressing MALAT1 and CDC42, respectively. The results showed that interference with CDC42 and MALAT1 expression inhibited the differentiation of BM-MSCs to ECs and the expression of endothelial marker-related proteins. Moreover, MALAT1 induced differentiation of BM-MCs to ECs through the CDC42/PAK1/Paxillin pathway was explored by transfecting si-MALAT1 and overexpressing CDC42 as well as PAK1 in the BM-MSCs. Next, miR-206 was overexpressed within BM-MCs to determine CDC42 expression. The binding sites of MALAT1, miR-206 and CDC42 were reported using luciferase. it was found that the MALAT1 competes with CDC42 3'-UTR for binding miR-206, which in turn is involved in differentiating BM-MSCs to ECs. Finally, DMED rat modeling success was demonstrated by APO experiments. MALAT1 overexpression-modified BM-MSCs had significant therapeutic effects in DMED rats.

Background In 1999, 1 year after the approval of the first oral phosphodiesterase type 5 (PDE5) inhibitor for the treatment of erectile dysfunction (ED), the first Princeton Consensus Conference was held to address the clinical management of men with ED who also had cardiovascular disease. These issues were readdressed in the second and third conferences. In the 13 years since the last Princeton Consensus Conference, the experience with PDE5 inhibitors is more robust, and recent new data have emerged regarding not only safety and drug–drug interactions, but also a potential cardioprotective effect of these drugs. Aim In March 2023, an interdisciplinary group of scientists and practitioners met for the fourth Princeton Consensus Guidelines at the Huntington Medical Research Institutes in Pasadena, California, to readdress the cardiovascular workup of men presenting with ED as well as the approach to treatment of ED in men with known cardiovascular disease. Method A series of lectures from experts in the field followed by Delphi-type discussions were developed to reach consensus. Outcomes Consensus was reached regarding a number of issues related to erectile dysfunction and the interaction with cardiovascular health and phosphodiesterase-5 inhibitors. Results An algorithm based on recent recommendations of the American College of Cardiology and American Heart Association, including the use of computed tomography coronary artery calcium scoring, was integrated into the evaluation of men presenting with ED. Additionally, the issue of nitrate use was further considered in an algorithm regarding the treatment of ED patients with coronary artery disease. Other topics included the psychological effect of ED and the benefits of treating it; the mechanism of action of the PDE5 inhibitors; drug–drug interactions; optimizing use of a PDE5 inhibitors; rare adverse events; potential cardiovascular benefits observed in recent retrospective studies; adulteration of dietary supplements with PDE5 inhibitors; the pros and cons of over-the-counter PDE5 inhibitors; non–PDE5 inhibitor therapy for ED including restorative therapies such as stem cells, platelet-rich plasma, and shock therapy; other non–PDE5 inhibitor therapies, including injection therapy and penile prostheses; the issue of safety and effectiveness of PDE5 inhibitors in women; and recommendations for future studies in the field of sexual dysfunction and PDE5 inhibitor use were discussed. Clinical Implications Algorithms and tables were developed to help guide the clinician in dealing with the interaction of ED and cardiovascular risk and disease. Strengths and Limitations Strengths include the expertise of the participants and consensus recommendations. Limitations included that participants were from the United States only for this particular meeting. Conclusion The issue of the intersection between cardiovascular health and sexual health remains an important topic with new studies suggesting the cardiovascular safety of PDE5 inhibitors.

Introduction Phosphodiesterase 5 inhibitors (PDE5-is) are used worldwide as first line therapy for erectile dysfunction (ED). Current literature reported data on the warning association between PDE5-is use and the development of cutaneous melanoma. However, these data are contrasting, thus we aim to summarise evidence regarding this association. Content A systematic review of all published articles related to the effects of PDE5-is in the development of cutaneous melanoma was performed. PubMed, EMBASE, and Cochrane library were queried for all the published studies indexed up to the 26th of May 2023. A combination of keywords related to PDE5-is and melanoma were used. Only original studies based on human subjects in the English language were included in the analysis. Summary and Outlook Of 505 articles identified, only eight original articles were considered for further analysis. Overall, five of the selected articles including 657,984 subjects agrees on an increased risk of developing melanoma in PDE5-is users. On the other hand, three original articles based on data regarding 360,915 subjects, disagree with the previous statement declaring any association between PDE5-i use and melanoma. Current literature still reports contrasting data regarding the association between PDE5-is assumption and increased risk of melanoma, but a possible association is described, bringing attention to higher risk melanoma category of patients. More clinical studies are needed to clarify the impact of PDE5-is in the development and progression of melanoma.
