Genomic Integrity: The Foundation of Cellular Stability and Human Health

Genomic integrity is crucial for maintaining cellular stability, ensuring proper physiological functions, and preventing diseases such as cancer. It refers to the stability and accuracy of the genome across generations, safeguarded by robust mechanisms that counteract genetic damage. DNA is continuously exposed to endogenous and exogenous stressors, such as reactive oxygen species, replication errors, and environmental agents like radiation and chemicals. To counteract these threats, cells have evolved sophisticated systems, including DNA damage recognition, repair pathways, checkpoint activation, and apoptosis. This article provides an in-depth exploration of the key mechanisms that preserve genomic integrity, the consequences of its disruption, and its implications for human health and disease. Emphasis is placed on the roles of DNA repair pathways, chromatin remodeling, genome surveillance, and therapeutic strategies to enhance genomic stability. Advances in understanding these processes have significant implications for developing treatments for genetic disorders, cancer, and age-related diseases.
