Type II Opsins in the Eye, the Pineal Complex and the Skin of Xenopus laevis: Using Changes in Skin Pigmentation as a Readout of Visual and Circadian Activity

Frontiers in Neuroanatomy, 2022
The eye, the pineal complex and the skin are important photosensitive organs. The African clawed frog, Xenopus laevis, senses light from the environment and adjusts skin color accordingly.

Taisho-Sanshoku koi have hardly faded skin and show attenuated melanophore sensitivity to adrenaline and melanin-concentrating hormone

Frontiers in Endocrinology, 2022
IntroductionKoi carp, an ornamental fish derived from the common carp Cyprinus carpio (CC), is characterized by beautiful skin color patterns. However, the mechanism that gives rise to the characteristic vivid skin coloration of koi carp has not been ...

Thyroid hormone regulates distinct paths to maturation in pigment cell lineages

eLife, 2019
Thyroid hormone (TH) regulates diverse developmental events and can drive disparate cellular outcomes. In zebrafish, TH has opposite effects on neural crest derived pigment cells of the adult stripe pattern, limiting melanophore population expansion, yet

Associations of MC1R Substitutions With Body Color Variation in a Desert Lizard. [PDF]

Ecol Evol
We successfully identified two amino acid substitutions (V165I and V237I) in MC1R that are significantly associated with body color variation between melanistic and non‐melanistic populations of a toad‐headed lizard, P. versicolor. In silico analysis revealed that both substitutions located in transmembrane (TM) domains affect the binding affinity ...

Melanophore Response and Behavior of the Marine Isopod Sphaeroma quadridentatum in the Presence of A Common Estuarine Predator Species [PDF]

, 2023
Sphaeroma quadridentatum (Say 1818) is a coastal species of marine isopod common in the US East and Gulf coasts that can be found in the TAMUG Small Boat Basin. S. quadridentatum has been shown to employ a melanophore response mechanism which changes the
