However, whether IL-4/IL-4Rα participates in skeletogenesis during embryonic development is not completely understood. We used the anti-IL-4Rα monoclonal antibody (anti-IL-4Rα mAb) as a powerful investigational tool to evaluate the potential roles of IL-4/IL-4Rα in the chondrogenic differentiation of rat bone marrow mesenchymal stem cells (BMSCs) in vitro. Simultaneously, we explored the effect of IL-4/IL-4Rα on bone ossification during rat embryo-fetal development. In this study, we found that, compared to the control group, IL-4 can significantly promote the chondrogenic differentiation of BMSCs. Furthermore, following exposure to anti-IL-4Rα mAb in pregnant rats, unexpected phenomena were observed in fetal bone development, including non-ossification of the fetal sternum, an incomplete ossification centre in long bones and a reduced number of ossification points in digit (toe) bones. To further investigate the underlying mechanism of the phenotype, we studied the rat sternum as the target organ, starting from different time points of sternum development in the embryonic stage. The results indicated that the retardation mainly occurred in the middle and late stages of embryonic development. This retardation was characterized by the inhibition of the differentiation process of mesenchymal stem cells into chondrocytes, resulting in reduced angiogenesis near the ossification centre, failure of osteoblasts to invade the centre of the cartilage body with the blood vessels and delayed formation of the primary ossification centre (POC). Overall, our study demonstrated the significant function of IL-4/IL-4Rα in chondrogenic differentiation of BMSCs and bone ossification during embryo-fetal development.</p>","PeriodicalId":8733,"journal":{"name":"Basic & Clinical Pharmacology & Toxicology","volume":"135 6","pages":"693-704"},"PeriodicalIF":2.7,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142456971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the benefits outweigh the risks, potential serious side effects must be considered, such as immune-related metabolic-endocrine adverse events (AEs). These AEs may correlate with increased progression-free survival and overall survival in ICIs; however, their role as predictive biomarkers is underexplored. Our study aimed to characterize the spectrum, frequency and clinical characteristics of immune-related metabolic-endocrine AEs, as well as other non-specific AEs, associated with ICIs and reported to the FDA Adverse Event Reporting System (FAERS).</p><p><b>Material and/or methods:</b> Data were collected from the FAERS database covering the period from the first quarter of 2012 to the fourth quarter of 2023. The definition relied on System Organ Class and Preferred Terms by the Medical Dictionary for Regulatory Activities (MedDRA). A preliminary descriptive analysis was then performed using R software (version 4.2.3). A Sankey diagram was built with the networkD3 package.</p><p><b>Results:</b> The total number of AEs in FAERS related to the selected drugs was 209 065. AEs were more common in men (53.9%) than women (34.8%). People over 65 years of age account for 40.1% of total AEs. Endocrine disorders represented 8.0% with 16 665 results. Metabolic disorders represented 9.6% with 19 983 results. The most common endocrine AEs were hypothyroidism (27.4%), adrenal insufficiency (18.6%) and hypophysitis (12.7%). The most common metabolic AEs were decreased appetite (27.9%), dehydration (12.6%) and hyponatremia (10.8%). These findings align with previous studies.</p><p><b>Conclusions:</b> This study explores the incidence of metabolic-endocrine AEs associated with ICIs treatment. The results show particularly high rates among older people and men. These findings provide a reliable basis for further comprehensive AEs' investigations. To establish reliable biomarkers for predicting the effectiveness of anti-tumour treatment, additional research and advanced statistical analyses are necessary.</p><p><b>#10</b></p><p><b>Safety of defibrotide in the prevention and treatment of acute respiratory distress syndrome in patients with COVID-19</b></p><p>P.

While this flexibility has undoubtedly expedited the availability of potentially life-saving treatments, based more in expectative that in robust evidence, it has concurrently ushered in a host of challenges that warrant careful consideration.</p><p>One of the foremost concerns pertains to the level of uncertainty tolerated during the approval of new medications. Notably, the approval of numerous oncological drugs based on surrogate endpoints, without concrete evidence of meaningful improvements in overall survival or quality of life, underscores the delicate balance between expediency and robust evidence. Furthermore, the emergence of additional toxicities associated with many of these approved drugs raises pertinent questions about the net clinical benefit conferred by these treatments.</p><p>The adoption of methodologies in clinical trials that permit early termination in response to favourable interim analyses introduces a layer of complexity, as premature cessation can inadvertently overestimate treatment effects, especially in the absence of rigorous blinding or controlled designs. This underscores the imperative for stringent scrutiny of trial data to ensure the reliability and generalizability of findings.</p><p>In parallel, drugs catering to niche patient populations, such as orphan medicinal products (OMPs) and advanced therapy medicinal products (ATMPs), often grapple with methodological limitations in clinical trials, resulting in approvals that are underpinned by scant evidence of efficacy and safety. This poses a considerable challenge for healthcare providers tasked with the management of the intricacies of treatment decisions in such contexts.</p><p>The pricing and reimbursement (P&R) landscape, too, is fraught with complexities, as stakeholders endeavour to strike a delicate balance between ensuring equitable access to innovative therapies and safeguarding the fiscal sustainability of healthcare systems.
