Because there is mounting evidence to suggest that oxidative stress is involved in the pathophysiology of albinism, albino amphibians are useful tools for studies on imbalances in the oxidant-antioxidant system. In the course of maintaining albino mu

Three cell lines have been established from melanotic and amelanotic melanophores of wild and albino Rana nigromaculata and albino Rana porosa brevipoda after experiencing three culture crises. The population doubling rate increased with culture time

Karyotypes of the Tago brown frog Rana tagoi and stream Tago brown frog Rana sakuraii from a mountain region in the Nishitama district in Tokyo were examined by conventional Giemsa staining, C-banding and late replication (LR)-banding. Chromosome num

A ventrally localized melanization-inhibiting factor (MIF) has been suggested to play a role in the expression of dorsal-ventral pigment patterns in amphibia. Here we investigate the onset and localization of MIF appearance in frog development. The e

A cDNA encoding tyrosinase of Rana nigromaculata was introduced into cultured, tyrosinase-negative amelanotic melanophores of R. brevipoda by a calcium phosphate precipitation method. Within a few days following transfection, dark pigmentation became

Three genomic DNA fragments containing the tyrosinase-encoding gene (TYR) of the Japanese pond frog, Rana nigromaculata, were cloned. The first, clone I, was isolated from a genomic library of sperm DNA using the mouse TYR cDNA as the probe and conta
