Over the past few decades, our understanding of the cell death mechanisms has expanded significantly revealing a diverse, and interconnected array of regulated cell death (RCD) pathways that includes apoptosis, necroptosis, pyroptosis, cuproptosis etc. While the complexities of these pathways have incrementally increased with the evolution of multicellularity, many core components associated with cell death have remained conserved. This points towards the essential function of cell death in maintenance of homeostasis at the cellular, organismal and individual level. It is thus not a surprise that their dysregulation can manifest in the form of several pathologies. Therefore, the ability to accurately detect and distinguish different forms of cell death is essential not only for advancing our understanding of the fundamental cellular and molecular processes but also for elucidating their role in disease pathogenesis, where their dysregulation contributes to various pathological conditions. However, detecting and differentiating various forms of cell death is a challenging task. Since there are multiple cell death modalities, many of their characteristics overlap, such as a condensed nucleus being observed in both secondary necrosis and apoptosis. Further, a cell can undergo more than one kind of cell death simultaneously, a process known as \"cell death continuum\" further complicating detection and classification. This chapter provides an overview of the conventional methods used for detecting cell death, highlighting both probe-based and non-probe-based techniques. Recent advancements in high-throughput strategies, AI based predictive modelling and other such novel techniques that offer greater specificity in cell death characterization are particularly emphasized.","PeriodicalId":49280,"journal":{"name":"Progress in Molecular Biology and Translational Science","volume":"217 ","pages":"25-65"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145126447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of its structural flexibility, it can stop denatured proteins from aggregating and building up within the lens over time. α-crystallin's dynamic quaternary structure, which allows it to exist in a variety of oligomeric forms, from dimers to massive assemblies, improves its chaperone function and flexibility. Its intrinsically disordered nature enables it to interact with a variety of client proteins due to its large non-polar and polar residue content and lack of a hydrophobic core. Furthermore, under physiological stress, osmolytes like sorbitol, TMAO, and urea are essential in regulating the stability and function of α-crystallin. Post-translational modifications (PTMs) such as glycation, in which reducing sugars combine with amino groups on the protein to generate advanced glycation end-products, impair α-crystallin's ability to function. These AGEs can cross-link α-crystallin molecules to prevent protein aggregation, changing their structure and decreasing their chaperone action. Because of their raised blood glucose levels, diabetics have an increased chance of developing cataracts as a result of this process. Comprehending how glycation and other PTMs affect α-crystallin is crucial for formulating treatment plans to maintain lens transparency and fight cataracts linked to aging and metabolic disorders.","PeriodicalId":49280,"journal":{"name":"Progress in Molecular Biology and Translational Science","volume":"211 ","pages":"89-111"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is also recognized that the phenomenon of protein intrinsic disorder contains keys to answer numerous questions that do not have obvious solutions within the classic \"lock-and-key\"-based structure-function paradigm. In fact, reality is much more complex than the traditional \"one-gene - one-protein - one-function\" model, as many (if not most) proteins are multifunctional. This multifunctionality is commonly rooted in the presence of the intrinsically disordered or structurally flexible regions in a protein. Here, in addition to various events at the DNA (genetic variations), mRNA (alternative splicing, alternative promoter usage, alternative initiation of translation, and mRNA editing), and protein levels (post-translational modifications), intrinsic disorder and protein functionality are crucial for generation of proteoforms, which are functionally and structurally different protein forms produced from a single gene. Therefore, since a given protein exists as a dynamic conformational ensemble containing multiple proteoforms characterized by a broad spectrum of structural features and possessing various functional potentials, \"protein structure-function continuum\" model represents a more realistic way to correlate protein structure and function.","PeriodicalId":49280,"journal":{"name":"Progress in Molecular Biology and Translational Science","volume":"211 ","pages":"1-15"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential to correct genetic mutations responsible for numerous hereditary disorders from single-gene disorders to complex polygenic diseases through precise DNA editing is feasible. The tactic now employed in CRISPR-Cas systems for treating inherited disorders is the usage of particular guide RNAs to target and edit disease-causing mutations in the patient's genome. Several methods such as CRISPR-Cas9, CRISPR-Cas12, and CRISPR-Cas13 are being thoroughly researched and optimized to increase effectiveness, accuracy, and safety in gene editing. Additionally, it is predicted that CRISPR-based therapies will be able to treat complex genetic illnesses such as cancer predisposition syndromes, neurological disorders, and cardiovascular conditions in addition to single-gene disorders. The available editing tools and creation of base editing technology facilitate the simultaneous correction of many mutations or accurate nucleotide changes leading to further advances in the development of multiplex editing tools and base editing technology fiction. When combined with other paradigms such as gene therapy using stem cell treatment, CRISPR-Cas promises improved efficacy. Patient treatment and lowering side effects significantly in individual genetic profiles will guide CRISPR-based treatments. These procedures will undoubtedly lead to therapies that are both efficient and curative of a wide range of genetic diseases, ushering in a new era of precision medicine.
