Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Targeted Mutation Species laboratory mouse Background Strain NOD/ShiLtJ Donor Strain 129S4 (J1 ES cell) Donating Investigator Stephan Martin, Dusseldorf at the Heinrich-Heine-Univers H2 Haplotype g7 Generation N2F3p Strain Description
Homozygous mutant mice are diabetes resistant. No membrane bound ICAM-1 is detectable in homozygous mutant mice. Histological examination shows no or only mild peri-insular infiltration at 330-410 days of age, By comparison, 64% of their wild-type and 44% of their heterozygote cohorts become diabetic by 310 days of age. In contrast to wild-type, 110-day-old ICAM-1 deficient females do not develop severe insulitis 10 days post cyclophosphamide treatment. Protection is associated with suppression of destructive insulitis as well as a deviation to a T-helper 2 cytokine mRNA expression pattern (Martin et al 2001).This targeted mutant strain is useful for studying the ICAM-1/LAF-1 interaction and its role in diabetes.
In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.
Strain Development
Intercellular adhesion molecule 1 (Icam1), located on Chr 9, 7cM, contains 7 exons and is one of the immunoglobulin superfamily that binds to the integrins LFA-1 and Mac-1 on leukocytes. A neomycin resistance cassette was inserted into exon 4 (one of the 5 Ig-like extracellular domains) of the Icam1 gene. J1 ES cell clone 74 was injected into B6 blastocysts. This Icam1 mutation has been backcrossed to NOD for at least 6 generations (Martin et al, 2001). The Type 1 Diabetes Resource received Stock No. 005983 - NOD.129S4(B6)-Icam1tm1Jcgr/SmtnJ in 2005. Shortly after arriving at The Jackson Laboratory additional genetic quality control indicated C57BL/6 genomic contamination on Chr 6 and 7. Markers D6Mit178, D6Mit52 and D6Mit135 on Chr 6 were segregating for both NOD and C57BL/6. Through selective breeding the Chr. 6 markers are NOD in origin. Markers D7Mit139, D7Mit96 and D7Mit328 on Chr 7 were found to be of C57BL/6 origin. After 2 crosses to NOD/ShiLtJ, all three Chr 7 markers were homozygous for the NOD-derived alleles. In 2007, this strain is at generation N?+N2F2.

| Molecular Note | A neomycin resistance cassette was inserted into exon 4 of the gene. While King, et. al. (J:25530) reported the potential for the production of functional proteins arising from alternative transcripts, corresponding signals were undetected by immunohistochemical analysis of homozygous mutant mice.

Cryopreserved Embryos This strain is also available as cryopreserved embryos from our Repository. Orders for cryopreserved embryos are supplied subject to a signed agreement that must be returned to the Customer Service Department after order placement. Experienced technicians at The Jackson Laboratory have recovered frozen embryos of this strain successfully. We will provide you enough embryos to perform two embryo transfers. The Jackson Laboratory does not guarantee successful recovery at your facility. For complete information on purchasing embryos from our repository, please visit our Cryopreserved Embryos web page. Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. |
