Emerging lipid-lowering therapies targeting proprotein convertase subtilisin/kexin 9 (PCSK9), lipoprotein(a), apolipoprotein C-III, and angiopoietin-like protein 3 represent promising advances in the management of patients with hyperlipoproteinemia. These therapies offer novel approaches for lowering pathogenic lipid and lipoprotein species, particularly in patients with serious perturbations who are not adequately controlled with conventional treatments or who are unable to tolerate them. Molecular targets for these novel therapeutic agents were identified and validated through genetic epidemiology studies. Proprotein convertase subtilisin/kexin 9 inhibitors (e.g., monoclonal antibodies and small interfering RNA) have revolutionized hypercholesterolemia management by significantly reducing both low-density lipoprotein cholesterol levels and major cardiovascular events. Genome editing of PCSK9 promises to provide a potential cure for patients with familial hypercholesterolemia. Several investigational lipoprotein(a)-targeting therapies aim to reduce the risk of atherosclerotic cardiovascular disease and aortic valve disease, although definitive clinical endpoint studies remain to be completed. Inhibition of APOC3 messenger RNA expression by olezarsen and plozasiran significantly lowers plasma triglyceride levels and markedly reduces pancreatitis risk in patients with familial chylomicronemia syndrome. Finally, angiopoietin-like protein 3 inhibition by the monoclonal antibody evinacumab has transformed management of patients with homozygous familial hypercholesterolemia. Together, these novel agents expand the therapeutic cache, offering personalized lipid-lowering strategies for high-risk patients with hyperlipoproteinemia, improving clinical outcomes and addressing previously unmet medical needs.</p>","PeriodicalId":49797,"journal":{"name":"Molecular Diagnosis & Therapy","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143061448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This issue is particularly critical for infectious diseases, where reliable and rapid diagnosis is crucial for effective treatment and easier containment, thereby reducing economic and societal impacts. Diagnostic technologies are vital in disease modeling, tracking, treatment decision making, and epidemic containment. At the point-of-care level in modern healthcare, accurate diagnostics, especially those involving genetic-level analysis and nucleic acid amplification techniques, are still needed. However, implementing these techniques in remote or non-laboratory settings poses challenges because of the need for trained personnel and specialized equipment, as all nucleic acid-based diagnostic techniques, such as polymerase chain reaction and isothermal nucleic acid amplification, require temperature cycling or elevated and stabilized temperatures. However, in smart food packaging, there are approved and commercially available methods that use temperature regulation to enable autonomous heat generation without external sources, such as chemical heaters with phase change materials. These approaches could be applied in diagnostics, facilitating point-of-care, electricity-free molecular diagnostics, especially with nucleic acid-based detection methods such as isothermal nucleic acid amplification. In this review, we explore the potential interplay between self-heating elements, isothermal nucleic acid amplification techniques, and phase change materials. This paves the way for the development of truly portable, electricity-free, point-of-care diagnostic tools, particularly advantageous for on-site detection in resource-limited remote settings and for home use.</p>","PeriodicalId":49797,"journal":{"name":"Molecular Diagnosis & Therapy","volume":" ","pages":"67-80"},"PeriodicalIF":4.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11742007/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645090","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}
