Key result
Ultraviolet radiation with anthracene induces DNA binding, protein crosslinking, and lipid peroxidation in vitro.
Why the study?
The effects of ultraviolet radiation in the presence of anthracene on covalent binding and damage to cellular macromolecules were investigated to understand molecular interactions under light exposure.
Ultraviolet radiation induces covalent binding of anthracene to cellular macromolecules, causing DNA damage, protein crosslinking, and lipid peroxidation.
These in vitro effects suggest possible phototoxic DNA risks; leaves open clinical translation or mechanistic extensions in photobiology.
Ultraviolet radiation (δ > 295 nm) induced covalent binding of anthracene to DNA which increased with time and was not affected by oxygen. Irradiation in the presence of anthracene induced nicking of Col E, circular DNA and decreased the thermal denaturation temperature of calf thymus DNA. These effects were oxygen dependent, and were decreased by GMP. Irradiation of anthracene and human serum albumin resulted in covalent binding of the hydrocarbon to the protein accompanied by crosslinking of the protein. Protein crosslinking decreased under anaerobic conditions. Irradiation of anthracene bound to liposomes induced lipid peroxidation which was not affected by superoxide dismutase or catalase.
