Strain Data Sheet



BRC No.RBRC00857
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.Cg-Treh<tm1Tkam>/Rbrc
Former Common nametrehalase Knockout mice
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strainC57BL/6JJcl
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Dr. Masashi Kurimoto, Biochemical Laboratories, Inc. in 2001-2002. A neomycin selection cassette replaced exons 5-10 of the Treh gene.
Strain descriptionB6;B6CB-Treh<tm1Tkam>. Targeted disruption of the trehalase gene. The mice with this mutant allele lack the trehalase activity in small intestine and kidney.
Colony maintenanceSibling x Sibling (Homozygote x Homozygote)Homozygous mutant mice are viable and fertile.
ReferencesTrehalose itself plays a critical role on lipid metabolism: Trehalose increases jejunum cytoplasmic lipid droplets which negatively correlated with mesenteric adipocyte size in both HFD-fed trehalase KO and WT mice.
