The stabilities, structures, and functions of nucleic acids are responsive to surrounding conditions. Living cells contain biomolecules, including nucleic acids, proteins, polysaccharides, and other soluble and insoluble low-molecular weight components, that occupy a significant fraction of the cellular volume (up to 40%), resulting in a highly crowded intracellular environment. We ...

Plasma membrane is an early target of polycyclic aromatic hydrocarbons (PAH). We previously showed that the PAH prototype, benzo[a]pyrene (B[a]P), triggers apoptosis via DNA damage-induced p53 activation (genotoxic pathway) and via remodeling of the membrane cholesterol-rich microdomains called lipid rafts, leading to changes in pH homeostasis (non-genotoxic pathway). As omega-3 ...
