Abstract: Methods are provided for the modulation of hSGLT3 protein glucosensor activity. The sensor is expressed in cholinergic neurons that regulate muscle activity, and in tissues including the brain and pacreas. The present invention also provides methods of identifying therapeutic compounds that modify the function of these sensors. Such therapeutic compounds have a functional effect on regulators of muscle activity, including gastrointestinal smooth muscles; on regulation of weight and metabolism; regulation of pancreatic function, including glucagons release; and in taste perception.

Abstract: Described is a transgenic non-human RS1?/? animal characterized in that it shows increased body weight, increased total fat and/or increased mean fat cell volume compared to a wild type animal. Also described are various uses of said animal, e.g. as an animal model for adipositas or hypercholesterolaemia, for identifying substances suitable for the therapy and/or prevention of adipositas or hypercholesterolaemia or for assaying the efficacy of dieting or pharmacological therapy of adipositas or hypercholesterolaemia. Finally, the use of compounds is described which are capable of modulating the activity/expression of RS1 for the treatment or prevention of diseases like adipositas or hypercholesterolaemia.

Abstract: A transport protein has been cloned which is present in liver epithelial cells and kidney epithelial cells and in intestinal cells and is responsible for transporting cationic pharmaceuticals and/or xenobiotics. This transport protein has been described more specifically by its DNA and amino acid sequences, and various uses are disclosed which are, in particular, of great importance for developing novel medicaments.
