Overview

Also Known As:C57 Leaden, L, Leaden

C57L/J mice are used widely in research as a general purpose strain. Mice have a high incidence of Hodgkin's-like reticulum cell neoplasm at 18 months of age and pituitary tumors in old multiparous females. C57L/J mice are highly susceptible to experimental allergic encephalomyelitis and highly responsive to phytohemagglutinin. In addition, C57L/J mice are highly susceptible to developing atherosclerotic aortic lesions following 14 weeks on an atherogenic diet. On a lithogenic diet, C57L/J mice develop gallstones as a result of abnormal regulation of cholesterol synthesis.

Detailed Description

C57L/J mice are used widely in research as a general purpose strain. Mice have a high incidence of Hodgkin's-like reticulum cell neoplasm at 18 months of age and pituitary tumors in old multiparous females. C57L/J mice are highly susceptible to experimental allergic encephalomyelitis (EAE) and highly responsive to phytohemagglutinin. In addition, C57L/J mice are highly susceptible to developing atherosclerotic aortic lesions (4500 to 8000 um² atherosclerotic aortic lesions/aortic cross-section) following 14 weeks on an atherogenic diet (1.25% cholesterol, 0.5% cholic acid and 15% fat) (Paigen et al. 1990). On a lithogenic diet, C57L/J mice develop gallstones as a result of abnormal regulation of cholesterol synthesis (Xua et al. 2004). C57L/J mice carry no detectable endogenous ecotropic MuLV DNA sequences.

Development

C57L/J mice were inbred following a mutation in a now extinct substrain of C57BR at F22. Inbreeding was carried out by J Murray at The Jackson Laboratory beginning in 1933. They were transferred to the production facility in 1947 at F45. The current generation of inbreeding is F203+.

Gene Symbol and Name	Obq3, obesity QTL 3
Gene Synonym(s)
Strain of Origin	C57L/J

Rmcf^s

Allele Symbol: Rmcf^s

Allele Name	MCF sensitive
Allele Type	Spontaneous
Allele Synonym(s)
Gene Symbol and Name	Rmcf, resistance to MCF virus
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	5
General Note	This locus controls resistance and susceptibility of cells in tissue culture to infection by mink cell focus-forming murine leukemia viruses. The allele Rmcf^r determines resistance and occurs in strains DBA/1, DBA/2, and CBA/Ca; the allele Rmcf^s determines susceptibility and occurs in strains AKR/J, C57BL/6, BALB/c, CBA/J, NFS, NZB, 129/J, and many others. Heterozygotes are as resistant as the resistant parent or nearly so. Rmcf is different from and independent of Fv1, a locus that controls susceptibility to infection by ecotropic viruses. Rmcf is located on Chr 5 close to Hm near the centromeric end (J:7108). Rmcf^r protects (AKR x CBA/Ca)F1 and (AKR x DBA/2)F1 hybrids from development of spontaneous thymic lymphomas and reduces the incidence of MCF-induced thymic lymphomas (J:7175). It also reduces susceptibility of cells of Sxv^s/Sxv^r mice to exogenous xenotropic viruses (J:7951). In addition, in strains susceptible to Friend virus-induced erythroleukemia, a condition thought to be due to the replication of MCF virus, Rmcf^r increases resistance to the virus-induced erythroleukemia. It may cause resistance by coding for or regulating the production of an MCF-related envelope glycoprotein that blocks the receptor for MCF viruses (J:8074). This conclusion is reinforced by the findings of Buller et al. (J:8497), who showed that the Rmcf^r allele contains an endogenous MCF gp70 env gene and that the Rmcf^s allele, at least in some strains (C57BL/6, CBA/J, and A/WySn), contains a xenotropic gp70 env gene. Presumably the MCF gp70 inhibits exogenous MCF infection in vitro by a mechanism of viral interference.
Molecular Note	This locus controls resistance of cells to infection by mink cell focus-forming murine leukemia viruses. The recessive s (susceptible) allele is found in AKR/J, C57BL/6, BALB/c, CBA/J, NFS, NZB and 129/J.

Cdh23^ahl

Allele Symbol: Cdh23^ahl

Allele Name	age related hearing loss 1
Allele Type	Spontaneous
Allele Synonym(s)	Cdh23^753A; mdfw
Gene Symbol and Name	Cdh23, cadherin 23 (otocadherin)
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	10
Molecular Note	Genetic complementation tests have shown allelism between the mdfw (modifier of deaf waddler) locus and the ahl locus. Further analysis has shown this is caused by a G to A transition at coding nucleotide position 753 of Cdh23 (SNP rs257098870). This hypomorphic allele changes splice donor site G-GT to A-GT, causing frame skipping of exon 7. This is predicted to delete part of the 2nd and 3rd ectodomains and cause reduced message stability. Twenty-seven strains classified with ahl and carrying the 753A allele include: CD-1, RBF/DnJ, PL/J, AKR/J, RF/J, BALB/cBy, A/WySnJ, P/J, SENCARA/PtJ, DBA/1J, ALS/LtJ, C58/J, C57BLKS/J, 129P1/ReJ, C57BR/cd, SKH2/J, BUB/Bn, MA/MyJ, LP/J, 129X1/SvJ, NOR/LtJ, A/J, C57BL/6, NOD/LtJ, DBA/2J, ALR/LtJ, C57L/J. Strains classified with ahl that DO NOT carry this mutation include: 129S1/SvImJ, C3H/HeSnJ, I/LnJ, YBR/Ei, MRL/MpJ.

Mx1^s1

Allele Symbol: Mx1^s1

Allele Name	myxovirus susceptibility 1
Allele Type	Spontaneous
Allele Synonym(s)
Gene Symbol and Name	Mx1, MX dynamin-like GTPase 1
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	16
General Note	The Mx genes determine resistance to the lethal effects of various myxoviruses including neurotropic avian influenza A virus injected intracerebrally, pneumotropic strains injected intranasally, and a hepatotropic strain injected intraperitoneally (J:5645, J:13136). Resistance is not dependent on presence of the thymus and is not abolished by immunosuppression or by inhibitors of macrophage function (J:5735, J:5478, J:5645). Resistance is specific for the orthomyxoviruses (J:6265). It is dependent on the presence of interferon-alpha and -beta but not -gamma (J:7365). The resistance allele at the Mx1 locus, under induction by alpha/beta interferon, produces the 75 kDa protein MX-1, which confers resistance to the influenza virus, in the nuclei of cells carrying the allele. Susceptibility alleles do not produce the protein (J:8273). The protein is located in the nucleus (J:7703) and produces its antiviral effect by preventing synthesis of viral mRNA in the nucleus (J:7992). Nuclear localization is necessary for anti-influenza virus activity (J:1417), but mutations induced in Mx1 showed that nuclear position was not sufficient for the effect; mutations in several domains can cause its loss (J:11840). The MX-1 protein is a GTPase containing a GTP binding domain (J:1417) and this binding core is also necessary (J:21243). Resistance is expressed by macrophages and other cells in vitro (J:6649, J:5940) but could not be transferred to susceptible animals by transfer of macrophages from resistant mice (J:6149). Resistance to infection with two tick-borne viruses, Thogoto virus (J:8273) and Dhori virus (J:27760), is also conferred by Mx1^r. The Mx1^r allele occurs only in strains A2G, SL/NiA, and T9, the latter being a strain derived from an influenza-resistant wild stock, and CAST/Ei, derived from Mus musculus castaneus. Most inbred strains, including C57BL/6J, C3H/HeJ, and BALB/cJ, carry an influenza susceptible Mx1^s1 allele which produces mRNA lacking exons 9, 10, and 11 of the Mx1^r allele. This large deletion apparently renders the protein incapable of providing resistance to influenza. The CBA/J, CE/J, I/LnJ, and PERA/Ei strains, also susceptible to the virus, have another form of the Mx1^s2 allele in which there is a nonsense mutation (J:9452). Interferon is induced by viral infection and in turn induces the Mx protein (J:7703). Although some interferon-induced genes respond directly to virus invasion as well as indirectly through induction by virus-induced interferon, this primary response is very weak for the MX-1 protein in response to either influenza or Newcastle disease viruses (J:1892).
Molecular Note	Many inbred mouse strains have an exon 9 to 11 deletion, resulting in a null allele and susceptibility to myxoviruses, including: A/J, ABP/Le, AKR/J, AU/SsJ, BALB/cJ, BDP/J, BUB/BnJ, C3H/HeJ, C57BL/6J, C57BL/10J, C57BL/KsJ, C57L/J, C58/J, DA/HuSn, DBA/2J, FSB/GnEi, FVB/NJ, LIS/A, LP/J, MA/MyJ, MAS/A, NZB/BINJ, P/J, PL/J, RIIIS/J, RF/J, SEA/GnJ, SEC1/ReJ, SJL/J, ST/bJ, TS1/A, TW1/A. YBR/Ei, 020/A, 129/J, SF/CamEi and SK/CamEi.

Chromosome	17

Ahr^b-1

Allele Symbol: Ahr^b-1

Allele Name	b-1 variant
Allele Type	Not Applicable
Allele Synonym(s)	Ah; Ah^b; Ah^b-1; Ahhⁱ; Ahr^b; In
Gene Symbol and Name	Ahr, aryl-hydrocarbon receptor
Gene Synonym(s)
Strain of Origin	C57BL/6J
Chromosome	12
General Note	C57BL/6 carries the responsive Ahr^b allele; DBA/2 carries nonresponsive Ahr^d. Heterozygotes (Ahr^b/Ahr^d) are responsive (J:5282). Later work identified a second (J:8895) and later a third (J:22144) allele conferring response. Thus the allele in C57, C58, and MA/My strains is now Ahr^b-1; Ahr^b-2 is carried by BALB/cBy, A, and C3H; and Ahr^b-3 by Mus spretus, M. caroli, and MOLF/Ei. The nonresponsive strains AKR, DBA/2, and 129 carry Ahrd (J:22144). Nucleotide and amino acid sequence differences between Ahr^b-1 and Ahr^d have been determined (J:17460). Strain of origin - this allele was found in C57BL/6, C58/J, C57BR, MA/My strains
Molecular Note	This allele encodes a high affinity, relatively heat stabile, 95 kDa receptor. PCR sequencing of cDNA revealed ten nucleotide differences between the coding sequences of the DBA/2J and C57BL/6J receptors. Five of the ten differences would cause amino acid changes. One of these, a C to T transition in exon 11 would change the arginine codon in the DBA/2J allele to an opal termination codon in the C57BL/6J allele. This change would prevent the 43 amino acid extension of mRNA translation predicted for the DBA/2J allele and account for the smaller size of the peptide produced by this allele (95 kDa vs 104 kDa for the DBA/2J allele). A second C to T transition changes a proline codon in the DBA/2J allele to leucine codon in the C57BL/6J allele, and would likely change secondary structure of the peptide and thus ligand affinity.

Mlph^ln

Allele Symbol: Mlph^ln

Allele Name	leaden
Allele Type	Spontaneous
Allele Synonym(s)	ln
Gene Symbol and Name	Mlph, melanophilin
Gene Synonym(s)
Strain of Origin	C57BR
Chromosome	1
Molecular Note	This allele has a C-to-T transition at mRNA nucleotide position 266. This introduces a stop codon at arginine codon 31 (p.R31*) in the sequence of the normally spliced transcript and it also creates a new G-GT splice donor site in exon 2. Use of this alternative splice site yields a transcript with an in-frame 21 base pair deletion that deletes 7 amino acids from the translated protein. Northern blots failed to detect this size difference and did not find any change from normal in transcript expression level. Sequence analysis failed to detect any wild-type transcripts.

Cox7a2l^l

Allele Symbol: Cox7a2l^l

Allele Name	long
Allele Type	Not Applicable (Not Specified)
Allele Synonym(s)	SCAF1¹¹³
Gene Symbol and Name	Cox7a2l, cytochrome c oxidase subunit 7A2 like
Gene Synonym(s)
Strain of Origin	multiple strains
Chromosome	17
General Note	Querying the sequences of the Sanger Mouse Genomes Project reveals that the short allele with its 6 bp deletion exists in C57BL/6J, C57BL/10J, C57BL/6NJ, C58/J, BALB/cJ, C3H/HeH, 129S5/SvEvBrd, NZW/LacZ, and SEA/GnJ, but the long allele lacking the deletion exists in 129S1/SvImJ, A/J, AKR/J, BTBR T⁺ Itpr3^tf/J, BUB/BnJ, C3H/HeJ, C57BR/cdJ, C57L/J, CAST/EiJ, CBA/J, DBA/1J, DBA/2J, FVB/NJ, I/LnJ, KK/HiJ, LEWES/EiJ, LP/J, MOLF/EiJ, NOD/ShiLtJ, NZB/BlNJ, NZO/HlLtJ, PWK/PhJ, RF/J, SPRET/EiJ, ST/bJ, WSB/EiJ, ZALENDE/EiJ.
Molecular Note	This allele encodes the long isoform with 113 amino acids. It is found in 129S2/SvPasCrl, CBA/CaOlaHsd, Hsd:ICR, and NZB/OlaHsd.

Payment Terms and Conditions

Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.

The Jackson Laboratory's Genotype Promise

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.
