Generation DefinitionsDonating Investigator Haiyan Xu, Rhode Island Hospital Description
These aP2-hIKKbeta SE transgenic mice express a constitutively active form of the human inhibitor of kappaB kinase beta (IKBKB) gene in adipose tissue under direction of the mouse fatty acid binding protein 4 (Fabp4) promoter. Hemizygous mice are viable and fertile. IKBKB gene product, IKKβ, is a master kinase involved in obesity-related inflammation and insulin resistance. These mice exhibit increased food intake, reduced weight of white adipose tissue, increased energy expenditure, and reduced triglyceride contents in adipose tissue, liver and muscle. They also exhibit reduced plasma free fatty acid (FFA) levels, increased systemic and tissue inflammation, decreased blood glucose levels, and improved glucose and insulin tolerance. These aP2-hIKKbeta SE mice show a decrease in hepatosteatosis even on a high fat diet. These mice may be useful for studying the effects of inflammation on adipose tissue and metabolism.Development
The aP2-hIKKbeta SE transgene was designed with a constitutively active form of the human inhibitor of kappaB kinase beta (IKBKB) gene driven by a mouse fatty acid binding protein 4 (Fabp4) promoter, followed by an SV40 polyadenylation site. The transgene was microinjected into fertilized FVB/NJ oocytes, and mice from founder line 49 were bred to C57BL/6 mice for at least five generations to establish a colony. Upon arrival at The Jackson Laboratory, transgenic mice were bred to C57BL/6J inbred mice (Stock No. 000664) to establish the colony.

Cryopreserved Mice - Ready for Recovery
Animals Provided
Price (US dollars $) Cryorecovery* $1980.00 At least two mice that carry the mutation (if it is a mutant strain) will be provided. Their genotypes may not reflect those discussed in the strain description. Please inquire for possible genotypes and see additional details below.
Standard Supply
Cryopreserved. Ready for recovery. Please refer to pricing and supply notes on the strain data sheet for further information.
Supply Notes
- Cryorecovery - Standard.
Progeny testing is not required.
The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided, their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders are needed. Animals typically ship between 11 and 14 weeks from the date of your order. If a second cryorecovery is needed in order to provide the minimum number of animals, animals will ship within 25 weeks. IMPORTANT NOTE: The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 (from U.S.A., Canada or Puerto Rico only) or 1-207-288-5845 (from any location).
