Strain Information

MCL1
Name: myeloid cell leukemia sequence 1 (BCL2-related)
Type: Gene
Species: Homo sapiens (human)
Chromosome: 1
Tg(MCL1)8Caig
Name: transgene insertion 8, Ruth W Craig
Type: Transgene
Species: Mus musculus (mouse)
Chromosome: unknown
Alteration at locus: Transgenic (random, gene disruption)
Genetic Alterations
Cloned fragments of human genomic DNA were used to prepare a transgene construct containing all exons and introns of Mcl-1, the 3′-untranslated region, and approximately 10.5 kb of the genomic 5′-flanking region and 1.7 kb of the 3′-flanking region.
Phenotype

Homozygous: Strain was not bred to homozygosity.

Hemizygous: Hematopoietic and lymphoid cells exhibit extended survival, which results in enlargement of the spleen and thymus. These survival-promoting effects occur in cells at specific stages of differentiation and under defined environmental conditions. This is exemplified in the thymus, where the transgene enhances viability in progenitors at the earliest stage of development. Enhanced viability in this tiny population of early progenitors has a marked effect, as it results in an overall expansion of all cells at subsequent stages of differentiation. A further example of the potential of MCL1-induced enhanced cell viability is that this allows for additional changes the result in the development of lymphoma upon long-term observation.

Strain Development
This mouse was derived by introducing a human MCL1 genomic construct onto a mixed background yielding B6;SJL-Tg(MCL1)8Caig/J, which has now been repeatedly backcrossed onto the C57BL/6NTac background. The rationale for developing this strain is as follows. MCL1 expression is normally increased in response to environmental signals in a cell type-specific manner. The original strain was made by introducing MCL1 at increased copy number under the control of its own promoter, the rationale being to allow for increased MCL1 expression in tissues that are normally subject to upregulation. To facilitate transplantation studies of the role of MCL1 in the immune response, this strain has now congenic on the C57BL/6NTac background .
Suggested Control Mice
Wild-type littermates or C57BL/6NTac mice.

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. (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.
