These Wnt-1/GAL4/cre-11 transgenic mice have expression of both Cre recombinase and the GAL4 transcriptional activator directed to midbrain and developing neural tube by the wingless-related MMTV integration site 1 (Wnt1) promoter/regulatory sequences. When Wnt-1/GAL4/cre-11 transgenic mice are bred to mice containing loxP site-flanked sequences, cre-mediated recombination results in deletion of the floxed sequences in the midbrain and developing neural tube of the resulting offspring.
Wnt-1/GAL4/cre-11 mice exhibit transgenic overexpression of Wnt1, both within and outside of the expected pattern of expression, which results in increased activation of WNT signaling, along with midbrain enlargement and accompanying loss of midbrain dopaminergic neurons (Lewis et al. 2013 Dev Biol 379:229). Further, it was reported in Goodwin et al. 2019 Genome Res. 29:494, that the Wnt1-cre transgene integrated into chromosome 11 causing a 31,283 bp deletion in the H2afv locus. In Stock No. 009107, founder line 1 had a copy number of greater than 5.

When homozygous for both co-injected transgenes, Wnt-1/GAL4/cre-11 transgenic mice are viable and fertile. Both Cre recombinase and the GAL4 transcriptional activator are expressed under the direction of wingless-related MMTV integration site 1 (Wnt1) promoter/regulatory sequences. Cre recombinase activity is detected in the Wnt1 pattern of expression: in the midbrain by 8.5 dpc and, after neural tube closure, in the dorsal and ventral midlines of the midbrain and caudal diencephalon, midbrain-hindbrain junction and dorsal spinal cord. Double transgenic mice exhibit psychiatric disorder-related behavioral abnormalities. Males, specifically, exhibit increased locomotor activity, increased anxiety, and decreased social interaction, while females exhibit impaired short-term spatial memory and nesting behavior. Both sexes have disordered cholinergic and glutamatergic fiber tracts from the medial habenula neurons in the interpeduncular nucleus.

When Wnt-1/GAL4/cre-11 transgenic mice are bred to mice containing loxP site-flanked sequences, cre-mediated recombination results in deletion of the floxed sequences in the midbrain and developing neural tube of the resulting offspring.
The transgenic line Wnt-1/GAL4/cre-11 was created by Dr. David H. Rowitch and Andrew P. McMahon (Harvard University). These mice resulted from co-injection of both the pWEXP2-GAL4 transgene (Wnt1-GAL4) and the pWEXP3C-cre transgene (Wnt1-Cre) into pronuclei of B6CBAF1/J (C57BL/6JxCBA/J) zygotes. Double transgenic mice from founder line 11 were obtained and bred with Swiss albino outbred mice. Double transgenic albino mice were sent to The Jackson Laboratory Repository in 2000 (as Stock No. 003829). Upon arrival, mice were bred together to establish the colony. The description of each transgene is below.
The pWEXP2-GAL4 transgene (Wnt1-GAL4) was designed by Dr. David H. Rowitch and Andrew P. McMahon (Harvard University) with the mouse Wnt1 promoter/enhancer elements upstream of a sequence encoding the full-length yeast GAL4 gene. Specifically, the Wnt1-GAL4 transgene was created by inserting a sequence encoding the full-length yeast GAL4 gene into a 10 kbp modified mouse Wnt1 genomic sequence at a polylinker site between the promoter and enhancer (the Wnt1 genomic sequence spans from approximately 1 kbp upstream of the translation initiation codon to approximately 5.5 kbp downstream of the polyA signal, and is modified with a polylinker that disrupts the translational start site and a reverse-oriented neo cassette in 3' UTR of exon 4).
The pWEXP3C-cre transgene (Wnt1-Cre) was designed by Dr. David H. Rowitch and Andrew P. McMahon (Harvard University) with the mouse Wnt1 promoter/enhancer elements upstream of a Cre recombinase cDNA sequence. Specifically, the Wnt1-Cre transgene was created by inserting the Cre recombinase cDNA into a 10 kbp modified mouse Wnt1 genomic sequence at a polylinker site between the promoter and enhancer (the Wnt1 genomic sequence spans from approximately 1 kbp upstream of the translation initiation codon to approximately 5.5 kbp downstream of the polyA signal, and is modified with a polylinker that disrupts the translational start site and a reverse-oriented neo cassette in 3' UTR of exon 4).
In Goodwin et al. 2019 Genome Res. 29:494, it was discovered that the Wnt1-cre transgene integrated into chromosome 11 causing a 31,283 bp deletion in the H2afv locus. In Stock No. 009107, founder line 1 had a copy number of greater than 5.

This strain has two co-injected transgenes that segregate together. When maintaining a live colony, transgenic carrier mice (harboring both co-injected transgenes) may be bred together, to to wildtype (noncarrier) mice from the colony, or occasionally to B6CBAF1/J hybrid mice (Stock No. 100011). Strain aggression is common and may require individual housing. On a different genetic background (see Stock No. 009107), it is reported that homozygous mice may be lethal as some offspring from transgenic carrier parents die around two months of age.
When using the Wnt-1/GAL4/cre-11 mouse strain in a publication, please cite the originating article(s) and include JAX stock #003829 in your Materials and Methods section.

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
