NOVEL CYTOGENETIC IMAGING APPROACHES FOR CHARACTERIZING CHROMOSOME CONDENSATION MECHANISMS

Abstract

Background: The condensation of chromosomes is a fundamental cellular process that is required for proper genome organization as well, chromosomal stability and accurate segregation throughout mitosis and meiosis. imperfections in compaction of chromatin and the chromosome organization lead to DNA instability, cancer development, and developmental disorders. Conventional microscopy methods generally do not have the resolution to allow detailed characterisation of chromatin structure.

Objective:The objective of this study is to assess new cytogenetic imaging methods in order to characterize the mechanisms of condensing of and the dynamics of chromatin throughout cell division at high resolution.

Method: We employed cutting-edge cytogenetic ways of imaging such as fluorescence imaging in situ hybridization (FISH), conventional confocal microscopy, STED ultra-resolution microscopy, cell-based imaging, as well as AI-assisted image analysis to investigate chromatin structure as well as chromosomal compaction in cultivated cellular systems.

Results: Advanced imaging systems displayed significantly higher resolution of chromatin structures (92%), enhanced imaging of normal condensation domains (88%), greater susceptibility to chromosome abnormalities (85%) and improved real-time tracking of chromatin (83%) compared with standard microscopy methods. In addition to integration of computation-based image processing and quantified chromatin analysis significantly improved the characterization of condensin-mediated genetic organization and remodeling of chromatin dynamics.

Conclusion: Novel cytogenetic imaging procedures convey powerful tools for understanding the mechanism of chromosome condensation using significant applications in genetic stability investigations, cancer cytogenetics, molecular diagnosis and precision medicine.
