| 004337 | 129(Cg)-Foxg1tm1(cre)Skm/J | Repository- Live |
| This strain expresses Cre recombinase from the endogenous Foxg1 locus. Forkhead box G1 is required for telencephalon development and is expressed specifically in the telencephalon and discrete head structures. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in tissue-specific deletion of the target. Recombination occurs in the telencephalon, anterior optic vesicle (developing lens and retina), otic vesicle, facial and head ectoderm, olfactory epithelium, mid-hindbrain junction and pharyngeal pouches. Mice that are homozygous for the targeted mutation die perinatally. Heterozygous mutant mice are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain represents a model that may be useful in studies of telencephalic development. | ||

Forkhead box G1 is required for telencephalon development and is expressed specifically in the telencephalon and discrete head structures.

Mice that are homozygous for the targeted mutation die perinatally. Heterozygous mutant mice are viable, fertile, normal in size. On the C57BL/6 background, forebrain volume in heterozygotes is substantially reduced especially in the cerebral cortex (40.7%), striatum (29.7%), and hippocampus (18.6%). In the adult, the thalamus is reduced in volume by 21.6%. This mutant mouse strain represents a model that ma

| 005964 | B6.Cg-Tg(GFAP-tTA)110Pop/J | Repository- Live |
| Mice hemizygous for the transgene are viable fertile, normal in size and do not display any gross physical or behavioral abnormalities. These mice express a tetracycline-controlled transactivator protein (tTA) driven by the human glial fibrillary acidic protein (GFAP) promoter. When these mice are mated to a second transgenic strain that carries a target gene under the regulation of a tetracycline-responsive promoter element (TRE; tetO), expression of the target gene in astrocytes in the bitransgenic offspring can be induced by withdrawal of the tetracycline analog, doxycycline. Doxycycline may be administered in the animals' water supply. This strain represents an effective tool for generating bitrangenic animals that may be useful to study inducible gene expression in the astrocytes of the central nervous system. | ||
| 003692 | B6;129X1-Sncatm1Rosl/J | Repository- Live |
| Homozygous null mice are viable, fertile, normal in size and do not display any gross abnormalities. No gene product (mRNA or protein) is detected in brain tissue. A wild-type complement of dopamine neurons, fibers and synaptic terminals is present and the overall brain architecture appears to be intact. They suffer from a reduction in total striatal dopamine and exhibit an attenuated locomotor response when given amphetamine. Normal dopamine release is observed upon stimulation of the nigrostriatal terminal with a single electrical pulse. When multiple stimuli are applied however, null mice exhibit an accelerated recovery of dopamine release. A similar acceleration is seen in wildtype mice in the presence of increased extracellular calcium. The phenotype observed in homozygous Snca-null mice suggests that Snca is an activity-dependent negative regulator of dopamine neurotransmission. | ||
| 003095 | B6.D2-ingls/J | Repository-Cryopreserved |
| Mice homozygous for the recessive ingls mutation are significantly smaller than their littermates, and their coat color is dilute with white underfur both dorsally and ventrally (Sweet 1991; Samples 2003). Most develop hydrocephalus with onset by one week of age. Homozygotes are weak and uncoordinated and have difficulty righting themselves. They fail to gain weight during the second week of life, and most die by three weeks of age. (Bronson et al. 2003) Length of survival appears to correlate with the severity of hydrocephalus, which varies from absent to severe; however, all homozygotes die by 4 weeks, whether or not they are hydrocephalic (Samples et al. 2003). Hydrocephalus affects the lateral ventricles most severely; serial sections reveal an intact cerebral aqueduct. Diffuse astrocytic hypertrophy and hyperplasia are observed in brains and spinal cords of mutant mice. A few mutants develop status spongiosis, and a few exhibit gliosis alone. Astrocytes cul

| 002642 | B6;129S-Gfaptm1Mes/J | Repository-Cryopreserved |
| Mice homozygous for the Gfaptm1Me targeted mutation are viable and fertile. Homozygous mutant mice show subtle changes in astrocyte morphology, CNS physiology, and enhanced LTP of both population spike amplitude and EPSP slope compared to control mice. Homozygotes are also hypersensitive to cervical spinal cord injury. These mice may be useful in studies dealing with transplantation, injury, or astrocyte biology. | ||
| 003487 | FVB/NJ-Tg(XGFAP-lacZ)3Mes/J | Repository-Cryopreserved |
| Mice carrying this transgene express beta galactosidase in the nuclei of astrocytes. The donating investigator reports that more recent studies on this particular line indicate low level expression of the lacZ reporter gene in many neuronal populations as well. The transgene integrated on the X chromosome and therefore undergoes X-inactivation. This strain may be useful for cell culture and transplantation studies. | ||
