The albino (tyrosinase, Tyrc), brown (tyrosinase-related protein 1, Tyrp1b) and slaty (tyrosinase-related protein 2, tyrp2slt) loci are all involved in the regulation of melanogenesis. Phenotypes of inbred mice mutant at two or more of these loci are not a ...

2000

More than 90 different loci influence pigmentation in the mouse. During the past few years, an increasing number of genes have been identified, and assigned to the corresponding coat color loci and pigmentation mutants. As a consequence, different names ha ...

Blockade of CD28/B7 co-stimulation by mCTLA4-Hgamma1 inhibits antigen-induced lung eosinophilia but not Th2 cell development or recruitment in the lung

Nicola Harris

We have studied the role of the CD28/B7 co-stimulatory pathway in the development of a Th2-type lung immune response. Mice injected two or three times intraperitoneally with ovalbumin in alum adjuvant and then re-exposed to the same antigen by intranasal ( ...

1997

Current evidence suggests that melanogenesis is controlled by epidermal paracrine modulators. We have analyzed the effects of transforming growth factor-beta1 (TGF-beta1) on the basal melanogenic activities of B16/F10 mouse melanoma cells. TGF-beta1 treatm ...

Tyrosinase, the key enzyme in melanin synthesis, is expressed in murine brain

Friedrich Beermann

Tyrosinase is one of the key enzymes in mammalian melanin synthesis. The pigment is produced in two different cell types: the pigmented epithelial cell of the retina, and the melanocyte, a cell of neural-crest origin. We recently showed that a fusion gene ...

Tyrosinase is a new marker for cell populations in the mouse neural tube

Friedrich Beermann

Tyrosinase, the key enzyme in melanin synthesis, is expressed in pigment cells derived from both neural crest and neuroectoderm. The present study was performed to detect tyrosinase promoter activity and tyrosinase gene expression during murine brain devel ...

1996

Tyrosinase and related proteins in mammalian pigmentation

Friedrich Beermann

Tyrosinase is the key enzyme in pigment synthesis, initiating a cascade of reactions which convert the amino acid tyrosine to the melanin biopolymer. Two other tyrosinase-related proteins (TRP) are known, TRP-1 (probably DHICAoxidase) and TRP-2 (DOPAchrome ...

Molecular basis of dark-eyed albinism in the mouse

Friedrich Beermann

Dark-eyed albino (C44H) is a recessive allele at the mouse albino (c) locus, which encodes tyrosinase (monophenol,L-dopa:oxygen oxidoreductase, EC 1.14.18.1), the key enzyme in melanin synthesis. Similar to type IB oculocutaneous albinism in humans, overal ...

Expression of the mouse tyrosinase gene during embryonic development: recapitulation of the temporal regulation in transgenic mice

Friedrich Beermann

Pigment in mammals is produced in melanocytes of the skin derived from the neural crest and in the pigmented epithelial cells of the retina derived from the optic cup. Tyrosinase (monophenol, L-dopa:oxygen oxidoreductase, EC 1.14.18.1) is regarded as the k ...

1992

Molecular characterization of the mouse tyrosinase gene: pigment cell-specific expression in transgenic mice

Friedrich Beermann

Tyrosinase is the key enzyme in melanin synthesis, and is expressed in the pigment epithelium of the retina, a cell layer derived from the optic cup; and in neural crest-derived melanocytes of skin, hair follicle, choroid, and iris. The tyrosinase gene has ...
