GLI-Similar 3(GLIS3) Knock Out (KO) Mice as Models to Screen Therapeutics for Diabetes, Polycystic Kidney Disease, and Hypothyro
Posted May 15 2012 8:00pm
Description of Invention: GLI-similar (Glis) 1-3 proteins constitute a subfamily of the Krüppel-like zinc finger transcription factors that are closely related to the Gli family. Mutations in human GLIS3 have been implicated in a syndrome characterized by neonatal diabetes and congenital hypothyroidism (NDH) and in some patients accompanied by polycystic kidney disease, glaucoma, and liver fibrosis. To further identify and study the physiological functions of GLIS3, NIEHS investigators generated mice in which GLIS3 is ubiquitously knocked out (GLIS3-KO) or conditionally knocked out in a cell type-specific manner. GLIS3-KO mice develop polycystic kidney disease, hypothyroidism, and neonatal diabetes, as indicated by the development of hyperglycemia and hypoinsulinemia. The pancreatic endocrine cells, particularly insulin-producing pancreatic beta cells, are greatly diminished in these mice. The pancreas-selective knockout mice GLIS3(Pdx1-Cre) develop severe diabetes within 2-3 months, much later than the GLIS3-KO mice. The kidney-selective knockout of GLIS3 (GLIS3(Ksp-Cre) mice lack expression of GLIS3 in the collecting ducts and develop severe polycystic kidney disease within a period of 2-4 months. These mice can be used as models to screen therapeutics for diabetes, polycystic kidney disease, and hypothyroidism.
