She had a history of obesity and stage 1B endometrial carcinoma treated with surgery and radiation 1-year prior. Despite several unsuccessful biopsy attempts and unclear imaging findings, she was ultimately diagnosed with a pelvic sidewall abscess secondary to a bowel microperforation, a rare late complication of radiation related to adhesions, weakened bowel, and peristalsis. Her condition was successfully treated with drainage and antibiotics. It is widely known that patients with endometrial cancer and comorbid obesity often experience diagnostic delay, weight stigma, and other barriers and thus deserve careful attention and continued advocacy.","PeriodicalId":73176,"journal":{"name":"Global translational medicine","volume":"95 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140228213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we review the methods of identifying the most efficacious drugs through these approaches for the treatment of cancer in detail. While various drugs have been identified for cancer treatment, there remains a pressing need for more relevant phenotypic assays. These assays aim to produce the desired disease phenotype, with a specific emphasis on highlighting targets rather than off-targets.

To elucidate the proteomic shifts in cardiac ECs accompanying MI-induced cardiac fibrosis, a standard MI mice model was established through ligation of the left anterior descending branch. Following 14 days of effective modeling, we isolated primary ECs from the hearts of both sham and MI models utilizing the CD31 microbeads sorting technique. Quantitative proteomics and bioinformatics methodologies, including tandem mass spectrometry, were employed to discern proteomic alterations in the primary endothelial cells of the experimental groups. Comprehensive analyses, including Gene Ontology analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, functional enrichment analysis, and functional enrichment cluster analysis, revealed an up-regulation of proteins associated with extracellular matrix-receptor interaction pathway in cardiac fibrosis post-MI. Subsequent Western blot analysis confirmed the up-regulation of specific proteins involved in this pathway, namely collagen type VI alpha 2 (Col6α2), vitronectin (Vtn), and integrin beta (Itgβ). We conclude that the expression levels of Col6α2, Vtn, and Itgβ in primary ECs during the early stage of cardiac fibrosis, 14 days post-MI, were significantly elevated compared to the sham group (P < 0.05). This observation suggests that ECM-receptor interaction could potentially influence the progression of cardiac fibrosis following MI.","PeriodicalId":73176,"journal":{"name":"Global translational medicine","volume":" 35","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139144788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on investigating pre- and post-operative concentrations of SCC antigen in blood serum, as well as the percentage of CXCR2-containing lymphocytes and CD44v6-containing monocytes in blood cell populations among patients with Stages I–II squamous cell lung cancer (SCLC) within 1 year after tumor resection. The primary objective was to assess their potential for predicting relapse. The study cohort comprised 57 patients (32 men and 25 women) with newly diagnosed squamous cell lung cancer (21 at stage I and 36 at stage II). Following tumor resection, categorized as R0 in terms of surgical intervention, all parameters were examined before surgery and at 3 weeks, 3 months, and 6 months postoperatively. Analysis revealed that the probability of relapse could be accurately predicted, ranging from 68.4% to 89.5%, based on differences in SCC antigen concentration, the percentage of lymphocytes with CXCR2, and monocytes with the CD44v6 receptor during various post-operative intervals. Subsequent regression analysis and the formulation of a combined model incorporating the above-mentioned parameters led to an enhanced predictive value for tumor recurrence, reaching 96.5% accuracy (with specificity at 95.6% and sensitivity at 100%). These results indicate the potential utility of the combined model as an additional marker for predicting postoperative relapse in patients with Stage I–II SCLC.","PeriodicalId":73176,"journal":{"name":"Global translational medicine","volume":"145 3‐9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139149347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Louridas","doi":"10.36922/gtm.1868","DOIUrl":"https://doi.org/10.36922/gtm.1868","url":null,"abstract":"Atherosclerosis and coronary artery disease are the main causes of impairment and cardiac death, placing a significant burden on our health-care system. This review focuses on elucidating the involvement of various epigenetic mechanisms in the genesis and progression of cardiovascular diseases (CVDs), particularly chronic CVDs. The deregulation of epigenetic mechanisms plays a crucial role in the progression of CVDs, prompting exploration into novel preventive approaches. Advancements in molecular procedures, network-based approaches, and data analysis have identified new targets in CVDs, permitting the utilization of individualized epigenetic factors for personalized diagnosis and treatment. While promising for improving diagnostic and prognostic assessments, the clinical implementation of epigenetic biomarkers lags behind. Multicenter clinical documentation in a large sample population is crucial to confidently ascertain the clinical utility of specific epigenetic biomarkers. Of particular interest is the interplay between epigenetics and the conflict between the gene-based reductionist theory and the holistic principle of systems biology (SB). The holistic principle analyzes the structural organization and regulation of biological networks, influencing the genesis and progression of complex cardiac diseases like CVDs. This review emphasizes the complexity of CVDs, elucidates the interrelationship between disease networks and epigenetic mechanisms, and highlights the importance of the holistic principle of SB, coupled with artificial intelligence, in clarifying this interrelationship. The constant and uninterrupted epigenetic impact holds immense potential for advancing our understanding of disease progression and treatment across cells and tissues. Despite these advancements, the full integration of the epigenetic impact into medical practice remains incomplete, with limited utilization in clinical applications. Nevertheless, it is likely that in the near future, the epigenetic regulation of gene expression, with its lifelong and extended effects on health, will become an integral part of everyday clinical practice.","PeriodicalId":73176,"journal":{"name":"Global translational medicine","volume":"226 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139152715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the disease progresses, integration of the viral genome into the host genome is often observed, yet the means of integration and its intrinsic relationship to carcinogenesis remain unclear. To address this gap, novel sequencing technologies have been developed to enhance the accuracy, intuitiveness, and cost-effectiveness of identifying integration breakpoints. HPV genome integration is thought to induce imbalances or dysfunctions in gene expression, epigenetic changes, chromosomal translocation, and genetic instability. The precise mechanisms underlying the changes in gene expression caused by genome integration offer avenues for tumor risk prediction and prognosis assessment. Personalized precision medicine, grounded in the integration patterns unique to each patient, holds promise for cancer treatment. This review summarizes and discusses the current state of knowledge regarding the mechanisms, carcinogenesis, detection and analysis, and clinical significance of HPV integration. It synthesizes existing information to offer a comprehensive overview, potentially enhancing our understanding of HPV-related tumorigenesis and aiding in the development of more effective diagnostic and therapeutic strategies.","PeriodicalId":73176,"journal":{"name":"Global translational medicine","volume":"105 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139176124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
