Genetic informationThe targeting construct comprises (5' to 3'): a 4.5 kb EcoRI-Sal I fragment of the desmin gene, a nls-lacZ cassette inserted in frame in the Sal I site of desmin exon 1 (pos. +608) followed by a pgk-neo cassette, a 2.5 kb Sal I-Sal I fragment containing the remaining region of exon 1 to the middle region of exon 6. The vector also contains a 3'-pgk/tk cassette, out of the region of homology with the desmin gene. ES cell clones were selected by ganciclovir/G418 double selection.
Phenotypic informationDesmin is a member of the intermediate filament family which forms a cytoskeletal lattice in all kind of muscle cells. In striated muscle, desmin links myobrils in parallel and in series between themselves and to the membrane cytoskeleton by interconnecting Z disks together and to the sarcolemma. Desmin is enriched at the myotendinous region in skeletal muscle and at the intercalated disks in cardiac myocytes. In smooth muscles, desmin filament link to dense bodies and dense plaques. Homozygous Des -/- mice are born and fertile with a reduced life expectancy (around 6 months). They develop a severe dilated cardiomyopathy evidenced by visible calcified lesions, as well as a skeletal myopathy and vascular and visceral smooth muscle defects. Desmin plays a crucial in the cellular transmission of active and passive force in striated and smooth muscles. Desmin was also found to play a role in the dynamic of mitochondria positioning in the heart and thereof in mitochondrial metabolism. The homozygous males are fertile but the homozygous females can be normally pregnant one time only, because desmin is involved in the smooth muscle of uterus. The heterozygous females do not have this problem.
Breeding historyBackcrossed more than 10 times to C57BL/6.

Order

Availabilities

Requesting frozen sperm or embryos is generally advisable wherever possible, in order to minimise the shipment of live mice.

  • Frozen embryos. Delivered in 4 weeks (after paperwork in place). €1740*
  • Rederivation of mice from frozen stock, delivery time available upon request . €3880*

Due to the dynamic nature of our processes strain availability may change at short notice. The local repository manager will advise you in these circumstances.

* In addition users have to cover all the shipping costs (including the cost for returning dry-shippers, where applicable).
