Differential expressions of melanocortin receptor subtypes in melanophores and xanthophores of barfin flounder

General and Comparative Endocrinology, 2010
alpha-Melanocyte-stimulating hormone (alpha-MSH) is a member of the melanocortin (MC) family, and the MC receptor (MCR) is a member of the G protein-coupled receptor (GPCR) superfamily. We previously found that in barfin flounder, a flatfish, alpha-MSH with an acetyl group at the N-terminus stimulated pigment dispersion in xanthophores; however, this ...

Transformation of amphibian xanthophores into melanophores in clonal culture

The Journal of Experimental Zoology, 1978
AbstractXanthophores isolated from bullfrog tadpoles were successfully cloned. The rapid disappearance of the yellow pigment‐containing organelles (pterinosomes) occurred in proliferating xanthophores and many black granules were newly synthesized in the cells. The granules were electronmicroscopically identified as melanin granules.

Local reorganization of xanthophores fine-tunes and colors the striped pattern of zebrafish

Science, 2014
Origin of fish pigment cell for pattern Zebrafish stripes arise from the interactions of pigment cells: black melanophores, iridescent iridophores, and yellow-orange xanthophores. Melanophores and iridophores develop from nerve-associated stem cells, but the origin of xanthophores is unclear.

Carotenoids, instead of pteridines, determine color of xanthophores and erythrophores in tilapia

Journal of Heredity
Abstract There has been controversy over whether the chromogenic substances of xanthophores and erythrophores are pteridines or carotenoids in fish. In this study, we first extracted and quantified carotenoids and pteridines from erythrophores and xanthophores in tilapia, respectively.

Rearrangements of pterinosomes and cytoskeleton accompanying pigment dispersion in goldfish xanthophores

Cytoskeleton, 1989
AbstractThe cytoskeleton of goldfish xanthophores contains an abundance of unique dense structures (400 nm in diameter) that are absent in goldfish nonpigment cells and are probably remnants of pterinosomes. No major difference in protein composition between xanthophores and nonpigment cells (without these structures) was found that could account for ...

Mutations affecting xanthophore pigmentation in the zebrafish, Danio rerio

Development, 1996
ABSTRACT In a large-scale screen for mutants with defects in embryonic development we identified 17 genes (65 mutants) specifically required for the development of xan-thophores. We provide evidence that these genes are required for three different aspects of xanthophore development.

Prolactin Signaling in Erythrophores and Xanthophores of Teleost Fish

Pigment Cell Research, 2000
Prolactin directly affects erythrophores and xanthophores of teleost fish, resulting in pigment dispersion. In the present study, signal transduction elicited by prolactin was examined using split‐tail fin preparations of the rose bitterling and Nile tilapia, and cultured erythrophores and xanthophores from the paradise goby and rose bitterling.

Epidermal xanthophores in a salamander

Canadian Journal of Zoology, 1973
Non-melanophore pigment cells are generally restricted to the dermis. In contrast, the xanthophores, forming the dorsal yellow stripe of the long-toed salamander, Ambystoma macrodactylum, are located within the epidermis. They are underlain by dermal iridophores and melanophores.

Actin‐dependent carotenoid droplet dispersion in permeabilized cultured goldfish xanthophores

Cell Motility, 1990
AbstractOrganelle translocations are essential cellular processes. Although much progress has been made with regards to microtubule‐dependent organelle translocations, little is known about actin‐dependent organelle translocation(s) except cytoplasmic streaming in Nitella.
