Methods and reagents for the diagnosis, prevention and treatment of insulin resistance using beta-arrestin2 and its up-regulators
View Patent ↗The present invention provides the use of βarrestin2 protein or its up-regulators for manufacturing a composition for the prevention or treatment of insulin resistance or related disease in mammals. The reagents and the kits for the specific identification of βarrestin2 protein or its coding gene or transcript are also provided which can be used in diagnosis of insulin resistance or related diseases.
1. A method for treating insulin resistance or an insulin resistance-associated disease in a mammal, comprising administering to the mammal a composition comprising a full-length βarrestin2 protein or an expression vector having a polynucleotide encoding the full-length βarrestin2 protein, wherein the insulin resistance-associated disease is selected from the group consisting of type II diabetes, obesity, hyperinsulinaemia, and glucose intolerance.
2. The method of claim 1 , characterized in that the expression vector is a plasmid vector.
3. The method of claim 1 , characterized in that the expression vector is a viral vector.
4. The method of claim 3 , characterized in that the viral vector is selected from the group consisting of retrovirus, adenovirus, herpes virus, vaccinia virus, and adeno-associated virus.
5. The method of claim 1 , characterized in that the mammal is a human.
