Foxo4L/L floxed mice may be useful for studying the regulatory role of the FOXO4 transcription factor on insulin signaling and tumor suppression.
Dr. Ronald DePinho, MD Anderson Cancer Center
These Foxo4L/L mutant mice possess loxP sites flanking exon 1 of the forkhead box O4 (Foxo4) gene. FOXO4 is a transcription factor involved in the regulation of insulin signaling, and is involved in tumor suppression by promoting cell cycle arrest and apoptosis. Mice that are homozygous for this allele are viable and fertile. When these mutant mice are bred to mice that express Cre recombinase, the resulting offspring will have exon 1 deleted in the cre-expressing tissue, resulting in inactivation of Foxo4 gene expression.
A targeting vector was designed to insert a loxP site upstream of exon 1, and a frt-flanked neomycin resistance (neo) cassette followed by a second loxP site downstream of exon 1 of the forkhead box O4 (Foxo4) gene. The construct was electroporated into 129S6/SvEvTac-derived TC1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and resulting chimeric mice were bred to Tg(ACTFLPe)9205Dym transgenic mice to delete the neo cassette. Progeny were crossed to remove the Flp-expressing transgene. Mice were bred to FVB mice for at least 3 generations before being bred with mice carrying Foxo1tm1Rdp and Foxo3tm1Rdp. Upon arrival, mice were bred to FVB/NJ inbred mice (Stock No. 001800) for at least one generation to establish the colony. The three alleles in this strain were separated and maintained as separate strains (for Foxo1tm1Rdp see Stock No. 024756 and for Foxo3tm1Rdp see Stock No. 024668). Single mutants were bred to FVB/NJ for at least one more generation.

Foxo4 is X-linked. When maintaining a live colony, homozygous females may be bred to heterozygous males.
When using the FoxO4L mouse strain in a publication, please cite the originating article(s) and include JAX stock #024757 in your Materials and Methods section.
|X linked - females are Heterozygous and males are wildtype for Foxo4<tm1Rdp>, 1 pair minimum|
We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We 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.
