Abstract
Advanced gene editing tools have transformed oncology by facilitating precise molecular therapies aimed at the hereditary basis of cancer. This thorough study examines the mechanisms, applications, and clinical implementation of advanced genome editing technologies in cancer treatment. This review commences with the molecular principles of genome editing and DNA repair mechanisms, systematically analyzing established technologies such as Zinc Finger Nucleases, Transcription Activator-Like Effector Nucleases, and various CRISPR/Cas systems (Cas9, Cas12, Cas13), in addition to novel advancements including base editors, prime editors, and the PASTE system. Additionally, hybrid platforms such as ARCUS, MegaTALs, and modified recombinases are examined, highlighting their amalgamation with artificial intelligence, biosensors, and synthetic biology concepts. The study outlines significant applications including functional genomics, disease modeling, synthetic lethality screening, and direct therapeutic interventions, with a specific focus on CAR-T cell engineering and immune checkpoint regulation. Applications unique to various cancer types are thoroughly examined throughout lung, breast, colorectal, hematologic, liver, pancreatic, head & neck, esophageal, prostate, gastric, and brain cancers. Significant obstacles such as delivery optimization via viral and non-viral vectors, tumor-specific targeting, off-target effects, immunogenicity, and ethical issues related to germline vs somatic editing are comprehensively examined. The translational landscape is analyzed via current clinical trials, regulatory structures, and the incorporation of organoid models and patient-derived xenografts for the advancement of personalized therapies. This review highlights the transformative impact of gene editing on cancer medicine, advancing toward more accurate, effective, and personalized therapeutic approaches.
Colorectal cancer (CRC) is a leading cause of cancer-related deaths worldwide, characterized by genetic heterogeneity and the accumulation of mutations in key oncogenes and tumor suppressor genes. CRISPR-Cas9 technology has greatly advanced genetic research by enabling precise genome editing. This review focuses on the innovative applications of CRISPR-Cas9 in CRC research, particularly its role in identifying novel therapeutic targets, elucidating mechanisms of drug resistance, and uncovering metabolic and stem cell pathway alterations in tumorigenesis. We highlight the diverse CRISPR systems, including Cas9, Cas12, Cas13, and advanced variants such as CRISPR activation (CRISPRa), CRISPR interference (CRISPRi), base editing, and prime editing, which have expanded gene knockout studies and enhanced our understanding of CRC. Despite these breakthroughs, challenges such as off-target effects and delivery limitations remain. Ongoing efforts to refine CRISPR technology aim to enhance its precision and clinical applicability, ultimately paving the way for more effective and personalized treatment strategies for CRC. In this review, we explore these advances and focus on the latest developments in CRISPR-based approaches for CRC treatment.

CRISPR has emerged as a next-generation gene-editing tool with the potential to target the molecular pathways associated with ageing and related disorders. It functions through RNA-guided Cas nucleases, directing DNA cleavage and utilizing the native DNA repair machinery for genetic manipulations. Advances in CRISPR technology have significantly enhanced the precision and flexibility of techniques for genome editing. The enzyme Cas9's ability to cut DNA at exact site has revolutionized genome editing by enabling accurate modifications within living eukaryotic cells. This review critically examines recent developments in CRISPR-based technologies, including Cas9, Cas12, base editing, prime editing, and CRISPR-mediated gene regulation. It highlights their rising applications in ageing research, with more emphasis on neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. The review also discusses the major pharmacological and translational challenges that currently limit clinical applications, including inefficient tissue-specific delivery, off-target genome editing, immunogenicity, manufacturing complexity, and long-term safety concerns. Also, recent progress in both, viral and non-viral delivery methods are critically evaluated, including adeno-associated viruses, lentivirus vectors, lipid nanoparticles, gold nanoparticles, exosomes, electroporation, and microinjection, is thoroughly discussed to highlight their therapeutic potential and translational limitations. Current studies indicate that CRISPR-based approaches have preclinical potential for targeting important hallmarks of ageing, particularly genomic instability, telomere attrition, and mitochondrial dysfunction. Other hallmarks of ageing, such as stem cell exhaustion, epigenetic modifications, and microbiome changes, are at earlier stages of development. Overall, this review describes future strategies for developing safe, precise, and clinically translatable CRISPR-based treatments to promote healthy ageing.
