Appearance
Strain developmentDeveloped by Jamie Modiano, University of Minnesota. The double mutant mice were generated by crossing with Nfatc2 KO (Anjana Rao, Harvard Medical School) and Tob1 KO(Tadashi Yamamoto, The Institute of Medical Science, Tokyo University).
Strain descriptionNfatc2 and Tob1 double knockout mice. Approximately 50% of Nfatc2 knockout mice develop B-cell lymphomas by 15-18 months of age. But, Nfatc2 and Tob1 double knockout mice do not have obvious gross phenotypes up to 6 months of age. Salivary glands showed lymphoid infiltration into the parenchyma, but no more severe than that observed in single Nfatc2 knockout mice, suggesting Tob1 neither accelerates nor delays lymphoid hyper-reactivity observed under conditions of Nfatc2 deficiency. Nfatc2 homozygous and Tob1 heterozygous dams generally fail to produce milk (so pups must be fostered). Histologically, adult female Nfatc2 homozygous/Tob1 heterozygous mice show comparable mammary development as wild type B6 mice, suggesting the inability to nurse pups is not due to anatomic defects in mammary development. Matings using Tob1 homozygous males created larger pups and more dystocias in the females.
Colony maintenanceNfatc2: Homozygote x Homozygote; Tob1: Wild-type (female) x Heterozygote (male) [or Crossing to C57BL/6J(Crlj)]
