In the present invention SLC5A9 gene (encoding SGLT4 protein) regulation was analyzed in the intestine of patients before and after weight-loss surgery. RNA scope analysis was used to determine the precise location of SLC5A9 in the human intestine and pancreas. Sglt4 knockout (KO) mice were created using CRISPR/Cas techniques, allowing to study changes in their metabolic phenotype for months while they were fed the WD (Western Diet). So, these data demonstrate that SLC5A9 mRNA levels are induced in the apical membrane of the intestine and exocrine pancreas in persons with obesity and Type 2 Diabetes. Furthermore, Sglt4 deficiency slows the onset of obesity and hyperglycemia in mice fed the WD, improving insulin sensitivity by improving beta cell function. Accordingly the present invention relates to a method for preventing or treating metabolic disorders by targeting the Sodium-Glucose-Co-Transporter-4 (SGTL4).
