Overview

Also Known As: loxTB Mc4r

Homozygous mice exhibit severe early-onset obesity, accompanied by hyperphagia, increased snout-anus length and hyperinsulinemia. The function of this disrupted allele can be restored by the enzymatic activity of Cre-recombinase. These mutant mice may be useful in studies of neurobiology, obesity, diabetes, hunger/appetite, and fat and energy metabolism.

Detailed Description

The mice have a loxp-flanked transcriptional blocking (loxTB) sequence that prevents normal endogenous gene transcription and translation from the endogenous locus. As such, homozygous mice are devoid of functional mRNA in all tested regions of the brain. Homozygous mice exhibit severe early-onset obesity, accompanied by hyperphagia, increased snout-anus length and hyperinsulinemia. The function of this disrupted allele can be restored by the enzymatic activity of Cre-recombinase. These mutant mice may be useful in studies of neurobiology, obesity, diabetes, hunger/appetite, and fat and energy metabolism.

When bred to a strain expressing Cre recombinase in the hypothalamus see Stock No. 006395 for example), this mutant mouse strain exhibits as intermediate phenotype in comparison to homozygous null mice.

When crossed to STOCK Slc32a1^tm2(cre)Lowl/J (see Stock No. 016962) Cre recombinase expression in inhibitory GABAergic neuron cell bodies results in offspring that exhibit obesity.

When crossed to B6;129S-Oxt^{tm1.1(cre)Dolsn}/J (see Stock No. 024234) Cre recombinase expression in oxytocin-expressing cells results in offspring that exhibit obesity.

Development

A targeting vector was designed to insert a loxp-flanked transcriptional blocker sequence (loxTB) between the transcriptional start site and ATG of the endogenous gene. The blocker sequence contains an SV40 enhancer, neomycin resistance gene, two HSV-TK polyA sequences, and an additional transcriptional pause signal from the pGL3-control vector. The construct was electroporated into 129S4/SvJae-derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. Chimeric mice were bred to C57BL/6 mice. Mutant mice heterozygous for the "loxTB Mc4r" allele were bred together and maintained as such prior to arrival at The Jackson Laboratory.

Mc4r^tm1Lowl

Allele Symbol: Mc4r^tm1Lowl

Allele Name	targeted mutation 1, Bradford B Lowell
Allele Type	Targeted (Conditional ready (e.g. floxed), Null/Knockout)
Allele Synonym(s)	Mc4r^tb; loxTB Mc4r
Gene Symbol and Name	Mc4r, melanocortin 4 receptor
Gene Synonym(s)	Fatboy; Glu3; glucose 3
Strain of Origin	129S4/SvJae
Chromosome	18
Molecular Note	A loxP flanked PGK-neomycin selection marker inserted in the 5' UTR created a null allele. Cre recombinase deletes the selection marker, restoring normal activity of the allele. Mice fail to respond to MC4R agonist MTII. This is a null allele that can be "reactivated" by cre recombinase.
