| 000805 | CBy.RF-Tshrhyt/J | Repository- Live |
| Mice homozygous for the hypothyroid spontaneous mutation (Tshrhyt) are characterized by growth retardation, low thyroid hormone levels, elevated thyroid stimulating hormone (TSH) and hypoplastic thyroid glands. Homozygous mice of both sexes are infertile but fertility as well as growth can be restored by treatment with thyroid hormone. The mice do not respond to exogenous TSH. Homozygous mutant mice also display audiotory defects characterized by morphologic abnormalities of the stereocilia on both inner and outer hair cell systems | ||
| 001743 | STOCK dwg/J | Repository- Live |
| Mice homozgyous for the dwarf grey spontaneous mutation (dwg) are viable but do not breed. Homozygous mutant mice have grey coats, are smaller than littermates, and develop cataracts by 3-4 weeks of age. Additional characteristics include increased numbers of osteoclasts, reduced bone mass, reduced red pulp area of the spleen, and slightly reduced thyroxin levels. | ||
| 003100 | STOCK dwgBayer/J | Repository- Live |
| The dwarf-Bayer mutation (dwgBayer) occurred spontaneously in an embryonic stem cell line during genetic targeting of the insulin receptor gene. The phenotype of the mice resemble drawf grey (dwg, Stock No. 001743) and subsequent characterization determined that the two mutations are allelic. Homozygous mutant mice are grey and smaller in size than wildtype littermates. | ||
| 003462 | B6.129S1-Thrbtm1Df/J | Repository-Cryopreserved |
| Mice homozygous for the Thrbtm1Df targeted mutation are viable and fertile displaying normal growth rates. Homozygous mutant mice exhibit goiter and elevated levels of both thyroid hormone and thyroid stimulating hormone. Defects in liver responses to thyroid hormone and subtle behavioral abnormalities are observed. The mice fail to develop normal hearing, as assessed by impaired auditory-evoked brainstem responses, and are susceptible to audiogenic seizures. This strain provides a recessive model for the human syndrome of generalized thyroid hormone resistance (GTHR). | ||
| 004858 | B6;129S1-Tshrtm1Rmar/J | Repository-Cryopreserved |
| Mice that are homozygous for the targeted mutation exhibit delayed eye opening, are runted by day 21, and will die within 1 week if weaned at day 21. Homozygotes will survive by extending weaning to 28 days but will not reproduce. Homozygotes are viable and fertile when weaned at day 21 and subsequently placed on a hormone replacement therapy diet consisting of a 100ppm desiccated thyroid powder supplement. No gene product (mRNA or protein) is detected by RT-PCR or Western blot analysis of thyroid membranes. Enhanced Green Fluorescent Protein (EGFP) gene product is detected by RT-PCR and Western blot analysis of thyroid tissue. Hypothyroidism is exhibited by mutant mice that have a longer weaning period and a non-supplemented diet, as indicated by low T4 and T3 serum levels, and high thyrotropin (TSH) serum levels. Treatment with exogenous TSH does not result in a thyroid hormone release response. Mutant mice produce uniodinated thyroglobulin and do not accumulate radioactive iodide in

| 002494 | B6;129S2-Cgatm1Sac/J | Repository-Cryopreserved |
| Mice homozygous for the Cgatm1Sac targeted mutation are viable but both sexes are infertile. They lack TSH, LH, and FSH. Homozygous mutant mice are hypogonadal and exhibit severe hypothyroidism resulting in dwarfism. Development of the thyroid gland was arrested in late gestation. However, gonadotropin releasing hormone (GNRH) neuron migration, development of secondary sex organs, and fetal and neonatal gonadal development are normal. Mice heterozygous for the Cgatm1Sac targeted mutation appear normal. | ||
| 000936 | CBy.AK-Tgcog/J | Repository-Cryopreserved |
| The Tgcog mutation causes the development of goiters due to failed processing of thyroglobulin. Homozygotes are smaller in overall size by 15 days of age. They display an increase in growth rate at the time of weaning but generally do not attain comparable size with their wildtype littermates. Increased thyroidal volume is apparent at embryonic day 18, and continues enlarging to an average of 5 fold higher than normal at 8 weeks of age and 20 fold normal at 10 months of age. In addition to decreased serum T3 and T4 levels, homozygotes have increased serum thyroid stimulating hormone levels, reduced levels of serum IGFBP-3, IGFBP-4, and IGFBP-2, mild anemia, and hypomyelination restricted to the cerebrum. Tgcog is an outwardly recessive mutation, but microdissection reveals a heterozygous phenotype as well. Thyrofollicular cells of heterozygotes have swollen protein-containing vesicles similar to but more moderate than those found in homozygotes

| 006023 | NOD.Cg-H2-Ab1tm1Gru Tg(CD4,HLA-DQA1,HLA-DQB1)N8Ell/EllJ | Repository-Cryopreserved |
| This NOD congenic strain contains a targeted H2-Ab1 mutation also carries two transgenes: one expressing human CD4 under the regulation of the mouse Cd4 enhancer and a second expressing human HLA-DQ6. The latter transgene confers dominant protection to development of Type 1 diabetes in humans. These double transgenic, H2-Ab1-deficient mice are viable, fertile, normal in size, and free of both autoimmune diabetes and cardiomyopathy, a phenotype found in an NOD stock expressing an HLA-DQ8 transgene (Elliot JF et al. Proc Natl Acad Sci U S A 2003; 100:13447-52). By 55 weeks of age, 100% of the H2-Ab1-deficient, DQ6 transgenic mice develop thyroiditis and thyroid autoantibodies. Of these, 25% develop thyroid gland enlargement and goiter, and a subset of these animals develops thyroid failure with elevated serum TSH levels.
This model is useful for studying autoimmune thyroid disease and to understand the role of MHC class II in au

| The Tgncog mutation causes the development of goiters due to failed processing of thyroglobulin. Homozygotes are smaller in overall size by 15 days of age. They have an increase in growth rate at the time of weaning but generally do not attain comparable size with their wildtype littermates. Increased thyroidal volume is apparent at embryonic day 18 and continues enlarging to an average of 5 fold higher than normal at 8 weeks of age and 20 fold normal at 10 months of age.

Thyrofollicular cells of heterozygotes have swollen protein-containing vesicles similar to but more moderate than those found in homozygotes.
