Animal models transgenic mice

Non-traditional animal model Transgenic mice carrying appropriate human receptor. Antibody formation would need to be monitored, as it is probable that a large human protein would produce an immune response. 

The clinical consequences of the currently used benzodiazepines range from sedation, muscle relaxation, seizure reduction, anxiolysis, and hypnosis. Clearly, it would be highly desirable to be able to separate some of these effects. In addition, it would be useful to reduce other undesirable consequences such as development of tolerance and dependence, abuse, synergistic interaction with ethanol, and memory impairment (for a comprehensive review see [22]). Animal models for some of the aforementioned conditions, in combination with transgenic mouse technology, have recently led to a deeper understanding of the contribution some of the individual a subunits make to these behaviors. 

Various animal species have been exploited in experimental atherosclerosis research, but nowadays most of the research is performed in mice [139]. This species has the advantage of developing atherosclerotic lesions in a relatively short period of time. The emergence of a broad variety of knock-out and transgenic mouse strains has led to a huge increase in the atherosclerosis research performed in this species. Mice are resistant to atherosclerosis when fed a normal low-fat chow diet, but they can develop atherosclerotic lesions after hypercholes-terolaemia has been induced. The three most widely used models in research on atherosclerosis are diet-induced, apoE deficiency-induced or LDL receptor deficiency-induced [139]. 

A second animal model uses H-ros transgenic mice (Oncomouse ) which spontaneously develop mammary and salivary tumors.97 This model is considered to be more relevant to human cancer in that tumor initiation and growth is endogenous, in contrast to nude mouse tumor explants. Mice with palpable tumors between 50 and 350 mm3 were treated with either the ester prodrug 18c (40 mg/kg, once daily, s.c.) or vehicle, and the size of the tumors monitored over time.44 While...
