PEPTIDES THAT DOWN REGULATE THE ACTIVITY OF PLASMA MEMBRANE TRANSPORTERS INCLUDING SODIUM-D-GLUCOSE COTRANSPORTER SGLT1

摘要

The present invention relates to the use of a regulatory protein RS1 fragment or a nucleic acid molecule encoding said regulatory protein RS1 fragment for the preparation of a pharmaceutical composition for the amelioration, prevention and/or treatment of a metabolic disease or a secondary disorder caused by a (pathological) modification of homeostasis, wherein said RS1 fragment is characterized in comprising at least 3 consecutive amino acid residues as comprised in the amino acid sequence S-D-S-D-R-I-E-P (Serine-Aspartic acid-Serine-Aspartic acid-Arginine- Isoleucine-Glutamic acid-Proline) or derivatives thereof. Furthermore, the present invention relates to a method for the amelioration, prevention and/or treatment of a metabolic disease or a secondary disorder caused by a (pathological) modification of homeostasis, said method comprising administering to a patient in need of such amelioration, prevention and/or treatment a pharmaceutically active amount of said regulatory protein RS1 fragment as defined herein or a nucleic acid molecule encoding said regulatory protein RS1 fragment. Moreover, the present invention relates to the use of said regulatory protein RS1 fragment or a nucleic acid molecule encoding said regulatory protein RS1 fragment for the preparation of food, feed and/or food supplements.
