Twitcher
Definition:
(n.) One who, or that which, twitches.
Example Sentences:
(1) In the twitcher mice with BMT examined at ages 44 and 71 days (transplanted at the day 9 to 12), degeneration of oligodendrocytes and myelin was still present.
(2) Also, the established twitcher cells were crossed with neomycin-resistant control human fibroblasts and selected in G418 medium.
(3) The assay conditions for both these activities in several mouse tissues have been optimized to facilitate the enzymatic characterization of homozygous and heterozygous twitcher mice.
(4) Although extensive demyelination was noted in the CNS of both mice and additionally, macrophage infiltration was pronounced in the twitcher, BBB remained intact to horseradish peroxidase.
(5) Boiled supernatant fractions, which contained saposins, were prepared from homogenates of twitcher brain, liver, kidney, and spleen.

(7) Although psychosine levels in sciatic nerves of HCT-treated twitcher mice increased more slowly than in the nerves of untreated twitchers, the levels in 100-day-old HCT-treated twitcher mice had reached the same high values as those seen in untreated 40-day-old twitchers.
(8) The effect on the activity of galactosylceramide beta-galactosidase as well as 4-methylumbelliferyl-beta-glucoside beta-glucosidase in the twitcher brain and liver homogenates by authentic saposin A and C was similar to that in control tissues.
(9) To determine whether Krabbe patients' cells complement twitcher cells to produce, in hybrid combination, greater than deficient levels of galactocerebrosidase activity, five separate crosses were made between an established twitcher mouse cell line and five cell strains from unrelated Krabbe disease patients.
(10) After postnatal day 10, the number of Schwann cell-axon units gradually increased and the number of unmyelinated axons per unit progressively decreased in the twitcher mouse.
(11) However, marked accumulation of psychosine was found in the 30-day-old-twitcher DRG.
(12) These data correlate well with the pathological changes; tissues containing higher concentrations of galactosylsphingosine show earlier and more severe pathological changes than those containing lower concentrations, thereby indicating the close link of galactosylsphingosine to the pathogenesis of the twitcher mouse.
(13) In attempts to elucidate the origin of accumulated galactosylsphingosine in the twitcher mouse, a murine model of human globoid cell leukodystrophy (Krabbe's disease), UDP-galactose:sphingosine galactosyltransferase activity was assayed in tissues from normal and twitcher mice.
