|The ht-PAC-377M transgenic mouse expresses all 6 human tau isoforms with 3 repeat (3R)-tau as the predominant isoform and 4 repeat (4R) -tau as the second most abundant isoform. Mutations in MAPT are associated with frontotemporal dementia with Parkinsonism linked to chromosome 17 (FTDP 17). Unpublished data suggests that these mice have behavioral deficits and oxidative damage in the brain. This mutant mouse strain may be useful in studies of tau isoforms in neurodegenerative disease.|

Homozygotes/Hemizygotes: Mice that are homozygous for the targeted mutation and hemizygous for the transgene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These double mutant mice produce mutated human tau (MAPT), while no endogenous mouse tau (Mapt) is produced. The ht-PAC-377M transgenic mouse expresses all 6 human tau isoforms with 3 repeat (3R)-tau as the predominant isoform and 4 repeat (4R) -tau as the second most abundant isoform. Mutations in MAPT are associated with frontotemporal dementia with Parkinsonism linked to chromosome 17 (FTDP 17). Unlike several of the other ht-PAC mutations, 377M does not influence exon 10 expression. Unpublished data suggests that these mice have behavioral deficits and oxidative damage in the brain. This mutant mouse strain may be useful in studies of tau isoforms in neurodegenerative disease.
The transgenic construct contains the 201 kb P1 artificial chromosome (PAC) 61D6 and includes 5 kb of sequence upstream of the human MAPT promoter and an additional 62 kb downstream of the 3' end of MAPT. The downstream segment also contains the 3' end of the gene KIAA1267, however, human MAPT is the only complete gene in the PAC. The construct includes the mutation V337M in exon 12 representing a GTG to ATG nucleotide substitution. This mutation results in an amino acid substitution of methionine for valine at position 337. This transgene was microinjected into fertilized C57BL/6 x C3H hybrid oocytes and founder mice were crossed to C57BL/6 mice for 15 generations. Mice were crossed to B6.129-Mapttm1Hnd mice to generate mice that are homozygous for the targeted mutation and hemizygous for the transgene. The colony was maintained by sibling mating. Upon arrival, mice were bred to C57BL/6J mice to establish the colony.
