- 論文の詳細を見る
Melanophores of a teleost Oryzias latipes permeabilized by treatment with a detergent, Brij 58, are capable of responding to epinephrine and melanocyte concentrating hormone (MCH) with melanosome aggregation. This response is totally and irreversibly prevented by the presence of a dynein ATPase inhibitor, sodium orthovanadate. Pigment aggregation in intact melanophores elicited by either epinephrine or MCH is also blocked by another inhibitor of dynein ATPase, erythro9 [3-(2-hydroxynonyl)] adenine (EHNA). These findings suggest that pigment aggregation is an ATP dependent process where dynein-like ATPase is probably involved. Melanophores which have been treated with Brij in the presence of epinephrine contain aggregated melanosomes. These preparations respond to a phosphodiesterase inhibitor, theophylline, with only a partial, slow pigment dispersion, which is prevented by the addition of vanadate. Neither cyclic AMP nor cyclic GMP is capable of eliciting pigment dispersal.
