Differentiation of zebrafish melanophores depends on transcription factors AP2 alpha and AP2 epsilon.

open access: yesPLoS Genetics, 2010
A model of the gene-regulatory-network (GRN), governing growth, survival, and differentiation of melanocytes, has emerged from studies of mouse coat color mutants and melanoma cell lines.

The expression of melanopsin and clock genes in Xenopus laevis melanophores and their modulation by melatonin [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2012
Vertebrates have a central clock and also several peripheral clocks. Light responses might result from the integration of light signals by these clocks. The dermal melanophores of Xenopus laevis have a photoreceptor molecule denominated melanopsin (OPN4x)

Characterization of the Leucistic Texas Rat Snake Pantherophis obsoletus

open access: yesFrontiers in Ecology and Evolution, 2021
Albinism and leucism are phenotypes resulting from impaired melanin pigmentation in the skin and skin appendages. However, melanin pigmentation of eyes remains unaffected in leucism.

Melanosome transfer, photoreception and toxicity assays in melanophores [PDF]

open access: yes, 2006
Many animals such as fish and frogs have developed the ability to change colour of their skin to adapt to the environment or to signal to other individuals. This ability is due to specialised skin cells called melanophores. Melanophores contain thousands

Generation of ornamental Nile tilapia with distinct gray and black body color pattern by csf1ra mutation

open access: yesAquaculture Reports, 2022
Nile tilapia (Oreochromis niloticus) is an important species in aquaculture and an excellent model fish for studying teleost color patterns. Colony-stimulating factor 1 receptor a (csf1ra) is critical for xanthophores development and body color formation

Melanophores [PDF]

open access: yes, 1998
Melanophores move pigment organelles (melanosomes) from the cell center to the periphery and vice-versa. These bidirectional movements require cytoplasmic microtubules and microfilaments and depend on the function of microtubule motors and a myosin ...

Molecular identification and morphological description of a Neoclinus chihiroe (Actinopterygii, Blenniiformes, Chaenopsidae) larva from the East Sea, Korea [PDF]

open access: yesActa Ichthyologica et Piscatoria
A single specimen of Neoclinus (family Chaenopsidae) was collected from the East Sea, Korea, in June 2016.This is the first report of the larval stage of Neoclinus chihiroe Fukao, 1987.

The effect of static magnetic field on melanophores in the sea trout (Salmo trutta m. trutta Linnaeus, 1758) embryos and larvae

open access: yesItalian Journal of Animal Science, 2019
Magnetic field affects many living organisms, fishes included. The fish reactions are observed from the early stage of development, during embryogenesis and larval period, and into adult stage.

Bar, stripe and spot development in sand-dwelling cichlids from Lake Malawi

open access: yesEvoDevo, 2019
Background Melanic patterns such as horizontal stripes, vertical bars and spots are common among teleost fishes and often serve roles in camouflage or mimicry. Extensive research in the zebrafish model has shown that the development of horizontal stripes
