Phase separation in biochemical and biological systems: Implications for disease pathogenesis.

Abstract

Phase separation is the phenomenon where distinct liquid phases within solution, play a critical role in the organization and function of biomolecular condensates within cells. Dysregulation of phase separation has been implicated, which can be witnessed in various diseases including neurodegenerative disorders, metabolic syndromes, and cancer. This review provides a comprehensive analysis of the role of phase separation in disease pathogenesis, which focuses on single amino acids, carbohydrates, and nucleotides. Molecular mechanisms underlying phase separation are also discussed with specific examples of diseases associated with dysregulated phase separation. Furthermore, consideration of therapeutic strategies targeting phase separation for disease intervention is explored.
