Triphenyltin induced darker body coloration by disrupting melanocortin system and pteridine metabolic pathway in a reef fish, Amphiprion ocellaris

Ecotoxicology and Environmental Safety
Triphenyltin (TPT) is a typical persistent organic pollutant whose occurrence in coral reef ecosystems may threaten the survival of reef fishes. In this study, a brightly colored representative reef fish, Amphiprion ocellaris was used to explore the ...

Influence of pteridines and statins on cancer: A therapeutic strategy targeting nitric oxide synthase (NOS) pathway

Advances in Redox Research
A family of enzymes known as nitric oxide synthases (NOS) produces nitric oxide (NO), a tiny, unstable, and potentially hazardous gas that is highly diffusible across cell membranes.
