Description

C57BL/6J DIO Control mice are provided a low fat diet with the same protein content as the diet provided to C57BL/6J DIO (diet-induced obese) mice. DIO controls do not develop the pre-type 2 diabetes phenotypes observed in DIO mice. Male C57BL/6J mice are placed on low fat diet at 6 weeks of age and study-ready animals are available between 7 and 20 weeks of age. For projects requiring a custom diet or a different strain, our project managers can work with you to get the mice you need.

Detailed description

In comparison to DIO mice fed a high fat diet, C57BL/6J mice fed a low-fat control diet do not become obese, maintain normal blood glucose and serum lipid levels, and have improved glucose tolerance (see detailed phenotypic data). They serve as a control for DIO C57BL/6J mice.

Development

The C57BL/6J inbred strain was created by Dr. CC Little from the mating of female 57 with male 52 from Miss Abbie Lathrop's stock. The same cross gave rise to the C57L and C57BR strains.

Symbol: Cdh23^ahl
Name: age related hearing loss 1
MGI accession ID: MGI:3028349
Generation method: Spontaneous
Synonyms: Cdh23^753A; mdfw
Marker symbol: Cdh23
Marker name: cadherin 23 (otocadherin)
Marker synonyms: 4930542A03Rik; ahl; bob; CDHR23; mdfw; nmf112; nmf181; nmf252; PITA5; sals; USH1D
Chromosome: 10
Strain of origin: multiple strains
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) at the 3' end of exon 7 (in ENSMUST00000073242). This hypomorphic allele changes splice donor site G-GT to A-GT, causing skipping of out-of-frame exon 7. This is predicted to delete part of the 2nd and 3rd ectodomains in the encoded peptide 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.

Symbol: Ahr^b-1
Name: b-1 variant
MGI accession ID: MGI:2667308
Generation method: Not Applicable
Synonyms: Ah; Ah^b; Ah^b-1; Ahhⁱ; Ahr^b; In
Marker symbol: Ahr
Marker name: aryl-hydrocarbon receptor
Marker synonyms: Ah; Ahh; Ahre; bHLHe76; dioxin receptor; In; RP85
Chromosome: 12
Strain of origin: C57BL/6J
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.
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).

Allele

Symbol: Aanat^{rs216509331-A}
Name: rs216509331 SNP allele with the A variant
MGI accession ID: MGI:2180134
Generation method: Spontaneous
Attributes: Hypomorph
Synonyms: Aanat^C57BL/6J; NAT
Marker symbol: Aanat
Marker name: arylalkylamine N-acetyltransferase
Marker synonyms: AA-NAT; DSPS; Nat-2; Nat4; SNAT
Chromosome: 11
Strain of origin: C57BL/6J
Molecular note: Low levels of melatonin production in C57BL/6J mice have been correlated with a point mutation in the gene encoding arylalkylamine N-acetyltransferase. A G to A conversion within a cryptic splice site results in the preferential incorporation of a pseudo-exon, containing an in-frame stop codon as the second codon, into the transcript. In vitro analysis demonstrates that the resulting truncated protein, which lacks several conserved C-terminal motifs, has less than 1% enzyme activity when compared to control C3H/HeJ mice.
General note: The A variant of this SNP has also been identified in strain LG/J.

Marker synonyms: IFI78; IFI-78K; lncMX1-215; MX; Mx-1; MxA; MXB; myxovirus (influenza) resistance 1 polypeptide
Chromosome: 16
Strain of origin: multiple strains
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.
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).
