Chromosome

Chromosomes are thread-like structures located within the nucleus of eukaryotic cells, composed of a single molecule of DNA and associated proteins, primarily histones, which package the DNA into a compact and organized form (NIH, 2023). They serve as the primary vehicle for the storage, transmission, and expression of genetic information, with humans typically possessing 23 pairs (StatPearls, 2023). While the term "Chromosomes" is generally considered too broad to be a specific therapeutic target, the structural and functional integrity of chromosomes is the ultimate focus of many medical interventions. In oncology, for instance, many traditional chemotherapies function by inducing DNA damage within the chromosome or by inhibiting the mechanical segregation of chromosomes during mitosis (NCBI, 2022). Structural abnormalities such as translocations, deletions, or aneuploidy are central to the pathogenesis of various cancers and congenital syndromes. Consequently, monitoring chromosomal stability remains a critical component of diagnosis and therapeutic efficacy assessment in genetic and oncological medicine.

Drugs targeting chromosomal processes act through DNA intercalation, covalent DNA binding (alkylation), inhibition of topoisomerase enzymes, or disruption of the mitotic spindle to prevent proper chromosome segregation and induce apoptosis.
