| Genetic information | Double transgenic mice carrying two constructs for doxycycline-mediated tyrosinase gene regulation (TET-ON model). Animal mouse model of oculocutaneous albinism type 1 (OCA1). It uses the first Tet system developed by H. Bujard and colleagues, therefore the version used of the transactivator was "Tet On/Off" (Tet On scheme, using rtTA) and the version of the Tet promoter was "PTRE". See PubMed ID:15250938. |
| Phenotypic information | In the off status, externally undistinguishable from a common albino phenotype. Upon doxycycline/tetracycline treatment from first gestational week pups will show a darker ruby eye colour. Coat colour is not modified by doxycycline/tetracycline treatment. |
| Breeding history | Transgenic mice were initially generated in FVB/HanHsd albino inbred mice but expanded in HsdWin:NMRI albino outbred mice to avoid the retinal degeneration mutation (Pdebrd1), carried by the FVB/HanHsd genotype. Mice were bred to double transgenic homozygosity and have been maintained since then as double transgenic homozygous in HsdWin:NMRI albino outbred mice (more than 20 generations). |
