TARDBP (NM_007375) was amplified from a human cDNA library (hTDP-43) and cloned into an mTUB expression vector containing a murine Thy-1 promoter. The expression vector was microinjected into pronuclear oocytes of Bl6/SJL mice. Founders were bred with C57Bl6/J mice.
Mutation: Overexpressing hTDP-43.
Promoter: Murine Thy-1 promoter.
Mouse strain: C57Bl6/J. Background strain: Bl6/SJL. Current Generation Number: ˜F4. Colony maintenance: Homozygous hTDP-43-overexpressing mice were generated for two selected lines by crossbreeding hemizygous hTDP-43-overexpressing mice.
Neuropathological analysis:
HOverexpression of WT TDP-43 leads to degeneration of specific neurons in the central nervous system, including spinal and cortical motor neurons and non-motor cortical neurons characteristically affected in FTLD-TDP, and causes spastic quadriplegia in a dose-dependent manner (ALS).
Behavioral Phenotype:
Abnormal limb reflex seen in highest expressing homozygous mice at ~ 14 days characterized by retraction of hindlegs toward the trunk upon lifting them by their tail.
At 18 days mice show poor motor performance on accelerating rotarod.
At ~22 days, fasciculations and spasms of facial muscles were observed, followed by an extremely rapid disease progression, with mice becoming completely paralyzed and dying within 3–4 days.
