title: Metabolic energy requirements during teleost melanophore adaptations.
abstract: Inhibition of oxidative phosphorylation by 2,4-dinitrophenol or sodium cyanide promotes complete melanosome aggregation in teleost melanophores. This aggregation is not promoted via the alpha-sympathetic receptor sites because it occurs in the presence of tolazoline hydrochloride, an alpha-receptor blocking agent. Interpretation of these results suggests metabolic energy release is required in the centrifugal direction only.
