  • They also found that the mice overfilled their bladders and took much longer to urinate than the normal mice. (redorbit.com)
  • mammalian
  • Only a few cell types express Cre recombinase and no mammalian cells express it so there is no risk of accidental activation of lox sites when using conditional gene knockout in mammals. (wikipedia.org)
  • Disorders
  • Gene targeting has already produced more than five hundred different mouse models of human disorders, including cardiovascular and neuro-degenerative diseases, diabetes and cancer. (scienceblogs.com)
  • models

  • Other mouse models are named according to their physical characteristics or behaviours. (wikipedia.org)
  • Alcohol and aldehyde dehydrogenases: retinoid metabolic effects in mouse knockout models. (nih.gov)
  • Elucidation of the vitamin A metabolic pathway and investigation of the endogenous function of vitamin A metabolites has been greatly improved by development of mouse ADH, RDH, and RALDH loss-of-function models. (nih.gov)
  • These mouse models serve as instrumental tools for providing new insight into retinoid function. (nih.gov)
  • Knockout animal models also have provided a platform on which to develop and test novel drug therapies. (britannica.com)
  • Furthermore, knocking out a gene may not produce any phenotypic change, and the changes observed in mouse models may be quite different from those observed in humans when the same gene is inactivated in both species. (britannica.com)
  • Genetically modified mice are used extensively in research as models of human disease. (wikipedia.org)
  • The disease symptoms and potential drugs or treatments can be tested against these mouse models. (wikipedia.org)
  • Multiple studies have been done using mouse knockout models to determine IRG function. (wikipedia.org)
  • chimeric
  • The resulting 'chimeric' animals carry some cells from their 'normal' mother and father, and some cells from the mouse that donated the EC or ES cells. (laskerfoundation.org)
  • The process would involve altering the cell's DNA in a culture dish and generating a chimeric mouse that incorporates that cell's new genetic information into its sperm and eggs. (laskerfoundation.org)
  • metabolic
  • Another mouse has had a gene altered that is involved in glucose metabolism and runs faster, lives longer, is more sexually active and eats more without getting fat than the average mouse (see Metabolic supermice). (wikipedia.org)
  • sperm
  • They contributed to most parts of the mouse, but it proved difficult to produce animals with the EC DNA in egg or sperm, an accomplishment that was essential to breed animals with the genetic change. (laskerfoundation.org)
  • abnormalities
  • Since UT-B has a wide tissue distribution, multiple phenotypic abnormalities have been found in UT-B null mice, such as defective urine concentration, exacerbated heart blockage with aging, depression-like behavior, and earlier male sexual maturation. (frontiersin.org)

  • human
  • Considering the high concentration of urea in human (285 mmol/L), rat (700 mmol/L), and mouse (1800 mmol/L) urine, the amount of urea in the urine should inevitably cause osmotic diuresis in the renal collecting ducts. (frontiersin.org)
