The Effect of The Divalent Cation Ionophore A23187 on Amphibian Melanophores and Iridophores
Journal of Investigative Dermatology, 1977 Calcium ions are required in the medium for the full darkening action of melanocyte-stimulating hormone, but not for its second messenger, cyclic adenosine monophosphate, on isolated frog skin. Thus, the possible effect of the divalent cation ionophore A23187 was studied, using the skin of Rana pipiens.

, 1988 Ofall amphibians living in arid habitats, reed frogs (belonging to the super species Hyperolius viridiflavus) are the most peculiar. Froglets are able to tolerate dry periods of up to 35 days or longer immediately after metamorphosis, in climatically ...

Ultrafast light sensing mediated by dermal iridophores in the silverside fish Hypoatherina tsurugae
Light-induced body color changes and direct optical sensing in the skin of amphibians and fishes have been debated for more than half a century. Previously reported chromatophore-mediated photoresponses generally occur on timescales of tens of seconds to

Local reorganization of xanthophores fine-tunes and colors the striped pattern of zebrafish
, 2014 The pattern of alternating blue and golden stripes displayed by adult zebrafish is composed of three kinds of pigment cells: black melanophores, yellow xanthophores, and silvery-blue iridophores.

Tunable structural color in organisms and photonic materials for design of bioinspired materials
Science and Technology of Advanced Materials, 2011 In this paper, the key topics of tunable structural color in biology and material science are overviewed. Color in biology is considered for selected groups of tropical fish, octopus, squid and beetle. It is caused by nanoplates in iridophores and varies

A Simple, Highly Visual in Vivo Screen for Anaplastic Lymphoma Kinase Inhibitors
, 2016 Anaplastic lymphoma kinase (ALK) is an important drug target in many cancers, including lymphoma, neuroblastoma, and lung cancer. Here, we demonstrate proof-of-principle for a novel and inexpensive assay for ALK inhibitor activity and identification in ...
