This strain is segregating for the retinal degeneration allele Pde6brd1.Strain Description
Mice that are homozygous for the targeted allele and hemizygous for the transgene are viable and fertile. Although no endogenous mouse MAPT is detected, all six isoforms (including both 3R and 4R forms) of human MAPT are expressed. Hyperphosphorylated MAPT is detected in cell bodies and dendrites by 3 months of age. Paired helical filaments of aggregated insoluble MAPT can be isolated from brain tissue as early as 2 months of age. These mutant mice may be useful in studies examining the relationship between human MAPT and Alzheimer's disease pathogenesis.Strain Development
Double mutant mice were generated by crossing transgenic mice (mouse line 8C) with Mapt targeted mutant mice. The targeted mutant allele was created by inserting EGFP coding sequence into the first Mapt exon, disrupting expression of the Mapt gene and producing a cytoplasmic EGFP protein fused to the first 31 MAPT amino acids (see Stock Number 004779). The transgenic allele consists of a PAC insert of 200-250 kb that includes the coding sequence, intronic regions and regulatory elements of the human MAPT gene. The targeted allele was created in 129S4/SvJae-derived J1 embryonic stem cells which were subsequently injected into C57BL/6 blastocysts. The transgenic allele was generated in embryos derived from a cross between Swiss Webster females and B6D2F1 males.

| General Note |
Pde6brd1, retinal degeneration 1, recessive. Formerly r, rd, rd1. A mutation causing retinal degeneration described by Bruckner (J:25576) and by Tansley (J:15333) in various stocks was later found to be present in many inbred strains (J:114). Keeler (J:5007) thought it to be identical with the rodless retina mutation he had described in 1924 (J:24999); the identity has recently been proven by analyses of DNA from Keeler's original slides (J:15231). Homozygotes are fully viable and fertile.Eyes develop normally up to 7 to 10 days after birth. At this stage the outer segment of the rod cell has begun to form, and in wild type mice it elongates rapidly during the 10th to 15th days. In Pde6brd1/Pde6brd1 mice the nascent outer segments and the rod cells degenerate rapidly so that by 15 days there is only a thin layer of rod cells left, and they have disappeared completely by 35 days (J:5250, J:5708). The inner nuclear layer and the retinal ganglion cells appear normal butmay show slight quantitative reduction (J:5812, J:5292). Although the eyes of Pde6brd1 homozygotes are devoid of normal rods, the mice have some visual capacity (J:5980). About 3% of cones among the visual cells degenerate at a much slower rate than do rods, so that a few cones are still present at 18 months (J:5988). The surviving cones are postulated (J:25157) as the light receptors required for the persistence of circadian responses to dawn and dusk in Pde6brd1 homozygotes past the sstage when rods have disappeared (J:29236). In fusion chimeras between wild type and Pde6brd1 homozygous embryos, the Pde6brd1 mutant acts in the photoreceptor cells rather than in the pigment epithelium of the retina (J:5708). Action within photoreceptor cells is also implied by the long term survival of wild type rod cells transplanted into Pde6brd1 homozygote retinas (J:20769). At a stage before degeneration can be seen, a deficiency of cGMP-PDE, andan excess of cGMP, appears in rod photoreceptor cells (J:5332). The rate of retinal degeneration in mutants doubly homozygous for two retinal degeneration mutations (Pde6brd1 and RdsRd2) is intermediate between those of the two homozygotes (J:12044). The double homozygote shows an intermediate level of mRNAs for the ß subunit of cGMP-PDE and for several other phototransduction related proteins, suggesting an interaction between Pde6brd1 and RdsRd2 (J:2579). Genbank ID for mutant sequence: M75166 | ||
| Molecular Note | Two mutations have been identified in rd1 mice. A murine leukimia virus (Xmv-28) insertion in reverse orientation in intron 1 is found in all mouse strains with the rd1 phenotype. Further, a nonsense mutation (C to A transversion) in codon 347 that results in a truncation eliminating more than half of the predicted encoded protein, including the catalytic domain has also been identified in all rd1 strains of mice. A specific degradation of mutant transcript during or after pre-mRNA splicing is suggested. [J:11513] [J:4366] [J:51361] | ||

Mapttm1GFPklt
Tg(MAPT)8cPdav
| Breeding & Husbandry | The targeted allele is maintained in a homozygous state while the transgenic allele is maintained in a hemizygous state. Mice that are heterozygous for the Mapt targeted mutation and hemizygous for the MAPT transgene will be distributed. Breeder pairs will also be heterozygous for the targeted allele and hemizygous for the trangene by the same. Expected coat color is agouti. |
