Genetic Alterations
This strain features human hepatic lipase cDNA in which an A to G nucleotide transition was introduced at position 559 leading to a change of the amino acid serine 145 to glycine resulting in catalytically inactive (ci) HL. The mouse HL sequences were amplified from an HL-specific BAC clone derived from a BAC library of the C57BL/6 mouse strain. The ciHL cDNA targeting vector disrupts the mouse hepatic lipase in exon 2 by in frame fusion of the human ciHLcDNA with the murine ATG transcriptional start site creating a humanized knock-in allele by homologous recombination in C57BL/6 embryonic stem cells. The targeting vector featured Neomycin-positive selection cassette flanked by lox P site, a 6.1 kb long homology region, a 1.6 kb short homology region and the 1.6 kb ciHL cDNA.
Genotype Determination
ES Cell Line
Not specified derived from C57BL/6
Phenotype

Homozygous: When compared to the hl-/hHL (MMRRC:041566) model, these mice display a lean phenotype, resistance to diet-induced obesity, reduced fat mass, reduced food intake, increased energy expenditure, and increased ambulatory activity. Background hepatic lipase activity is the same as hepatic lipase knockout mice.

Heterozygous: Not characterized

Strain Development
Successfully targeted ES cells were injected into blastocysts isolated from albino C57BL/6(C57BL/6J-Tyrc-2J/J) female mice. The injected blastocysts were reimplanted into OF-1 Peudopregnant mice. Male offspring with >50 % chimerism were bred with C57BL/6 Cre-recombinase expressing deleter mice to excise the neomycine selection cassette. Offspring were analyzed by PCR to verify excision of the neomycin selection cassette and to confirm absence of mouse hepatic lipase.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to mmrrc@missouri.edu for more information.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The donor or their institution limits the distribution to non-profit institutions only.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

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.
