The present invention relates to a pharmaceutical composition comprising a (poly)peptide which comprises or consists of QEP or a QEP derivative thereof a nucleic acid molecule encoding said (poly)peptide or a vector comprising said nucleic acid molecule, for use in the prevention or in the treatment of a disease or disorder caused by, physiologically linked to or associated with glucose and/or galactose uptake, wherein said pharmaceutical composition is to be administered under a high-sugar condition. Furthermore, the pharmaceutical composition of the invention is for use in increasing insulin sensitivity. The invention further relates to a food composition comprising said (poly)peptide. The invention further relates to a method of screening for and/or identifying a compound suitable to prevent or treat said disease or disorder under a high-sugar condition. The invention further relates to a method of screening for and/or identifying a compound which modulates ornithine decarboxylase (ODC), which is capable of inhibiting (SGLT1-mediated) glucose and/or galactose uptake into a cell expressing ODC and/or which is capable of increasing the inhibitory effect of an inhibitor of glucose and/or galactose uptake into a cell expressing ODC. The invention further relates to a method for predicting a patients non-response or response to said (poly)peptide, to a method for stratifying a patient for prevention or treatment with said (poly)peptide and to a kit for determining whether a patient suffering from said disease or disorder is a non-responder or responder to said polypeptide. The invention further relates to a method of developing and/or designing a compound/drug suitable to prevent or treat said disease or disorder.

Peptides derived from RS1 which down-regulate glucose absorption after a glucose rich meal and increase insulin sensitivity

A regulatory protein RS1 fragment or a nucleic acid molecule encoding the regulatory protein RS1 fragment for the preparation of a pharmaceutical composition, food and/or food supplements for the amelioration, prevention and/or treatment of a metabolic disease or a secondary disorder caused by a (pathological) modification of homeostasis, wherein the RS1 fragment is characterized in comprising at least the amino acid sequence Q-C-P Glutamine-Cysteine-Proline) or derivatives thereof, is provided. Also provided is a method for the amelioration, prevention and/or treatment of a metabolic disease or a secondary disorder caused by a (pathological) modification of homeostasis comprising administering a pharmaceutically active amount of a regulatory protein RS1 fragment or a nucleic acid molecule encoding a regulatory protein RS1 fragment, wherein the RS1 fragment comprises at least the amino acid sequence Q-C-P or derivatives thereof.

Tripeptides that down regulate the activity of plasma membrane transporters including sodium-D-glucose cotransporter SgIt1

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.
