Genetic Alterations
These OVE2353A-SB1 (OVE#2353A-SB1) mice harbor a mutation created by random insertion of the SB-cHS4core-SB-Tyro-WPRE-FUGW lentiposon transgene (LV2229), and the transposon was subsequently mobilized via exposure to sleeping beauty transposase (SB10) to generate the mutation. Using inverse PCR analysis, a chromosomal inversion was identified between intron 9 of the Smad4 gene (Smad4) on chromosome 18. The IR/DR is linked to the -)] strand of DNA at position nic[3'-86,038,197(-)] / Smad4[L3-73,805,670( bp [NCB137/mm9; agenic[3'-86,038,197(-)] / Smad4[L3-73,805,670(-)]]. The donating investigator reports the phenotype of homozygous mice as: flattened "pancake" appearance at embryonic day (E)9. When maintaining a live colony, heterozygous mice may be bred together, bred with wildtype siblings, or bred with FVB/N inbred mice (Stock No. 001800).These OVE2353A-SB1 (OVE#2353A-SB1) mice harbor a mutation created by random insertion of the SB-cHS4core-SB-Tyro-WPRE-FUGW lentiposon transgene (LV2229)nic[3'-86,038,197(-)] / Smad4[L3-73,805,670(

Strain Development
A lentiviral transgenic approach was used to generate these mice. The SB-cHS4core-SB-Tyro-WPRE-FUGW lentiposon transgene (LV2229) was designed with a Sleeping Beauty (SB) transposon (inward-facing SB arms flanking a tandem pair of cHS4 core insulator elements), followed by a mouse tyrosinase minigene (Tyro) and a woodchuck hepatitis virus post-transcriptional regulatory element (WPRE) in the FUGW self-inactivating HIV-based lentiviral vector backbone. The SB transposon and Tyro minigene replaced the ubiquitin-c promoter and EGFP sequences originally found in the FUGW lentiviral vector. The SB transposon used in this transgene has an inverted repeat/direct repeat sequence (IR/DR; the SB transposon recognition site), two copies of the 0.25 kb chicken beta-globin core insulator element (cHS4 core), and a second IR/DR sequence. The IR/DR sequences are inward-facing (pointed towards the cHS4core). The cHS4 core insulator element functions to terminate transcription of the upstream locus into which it integrates (and also enhance expression from the downstream Tyro minigene). The Tyro minigene is composed of the mouse Tyr enhancer region (623 bp), promoter region (657 bp), and 1566 bp cDNA sequence (including the stop codon); all in sense orientation relative to the FUGW backbone. There is no polyA site between the Tyro minigene and WPRE sequence. The WPRE sequence functions to enhance the mRNA transcript stability. This packaged lentiposon was injected subzonally (under the zona pellucida) into 1-8 cell stage FVB/N mouse embryos. Expression of the tyrosinase minigene results in melanin synthesis, so founder mice (F0) were identified by inspection for pigmentation. All F0 mice exhibited mosaic pigmentation. Most F0 mice had more than one lentiviral integration site. F0 mice were assigned an OVE number and then bred with FVB/N mice. Pigmented offspring (F1) with different coat colors were designated as subline A, B, C, etc., for each family. F1 mice were bred with FVB/N mice. F2 mice with different coat colors were designated as sublines A-1, A-2, etc., or B-1, B-2, etc. Breeding with FVB/N mice was continued until litters with only one or two different coat colors were obtained. Mice with identical coat colors were then inbred to generate homozygotes. Homozygous mice were viable and fertile. Homozygous females were bred to males with testes-specific expression of the SB transposase (PGK2-SB10 transgenic line OVE1780 on an FVB/N genetic background). The resulting double mutant male offspring ("seed males") have the ability to mobilize transposons in their germline; and mobilization from the inward-facing, IR/DR configuration leads to genomic rearrangements including deletions, inversions and translocations, in conjunction with loss of the cHS4 core insulator element initially located between the IR/DR elements. The seed males were bred with FVB/N wildtype females, and the offspring were screened for deletion of the core insulator element. Mice with transpositions (new F0 mice) were bred to FVB/N mice to establish new lines (SB1, SB2, etc.). F1 mice for each new line were inbred and assessed for the presence or absence of viable homozygotes. Hemizygous mice of line OVE2353A-SB1 (OVE#2353A-SB1) exhibit medium grey coat color. The donating investigator reports the PGK2-SB10 transgene was bred out of the line as well. Using inverse PCR analysis, a chromosomal inversion was identified on chromosome 18 between the original lentiviral integration site (agenic region linked to the (-) strand of DNA at position 86,038,197 bp [NCB137/mm9; 3'-86,038,197(-)]) and the transposition site (intron 9 of the Smad4 gene (Smad4); the left IR/DR is linked to the (-) strand of DNA at position 73,805,670 bp [NCB137/mm9; L3-73,805,670(-)]). Transgenic males were used to freeze sperm, and that cryopreserved sperm were sent to The Jackson Laboratory Repository node of the Mutant Mouse Regional Resource Center (MMRRC-JAX). Upon arrival, aliquots of this frozen sperm were used to fertilize oocytes from FVB/NJ inbred females (Stock No. 001800) to establish the live colony.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary.
