Enhancement of androgen action in the kidneys of transgenic mice harboring the mutant human UMOD gene.

Progressive accumulation of intrinsic mouse uromodulin in the kidneys of transgenic mice harboring the mutant human uromodulin gene.

Familial juvenile hyperuricemic nephropathy (FJHN) and medullary cystic kidney disease type 2 (MCKD2) are autosomal dominant disorders characterized by juvenile hyperuricemia of the underexcretion type, juvenile gout and chronic renal failure in the adult. FJHN/MCKD2 constitute diseases caused by mutations of the human uromodulin (UMOD) gene that encodes uromodulin, the most abundant glycoprote...

Development of Transgenic Mice Harboring Ovine Beta Lactoglobulin-Calcitonin Transgene

A transgenic mouse model for uromodulin-associated kidney diseases shows specific tubulo-interstitial damage, urinary concentrating defect and renal failure.

Uromodulin-associated kidney diseases (UAKD) are autosomal-dominant disorders characterized by alteration of urinary concentrating ability, tubulo-interstitial fibrosis, hyperuricaemia and renal cysts at the cortico-medullary junction. UAKD are caused by mutations in UMOD, the gene encoding uromodulin. Although uromodulin is the most abundant protein secreted in urine, its physiological role re...

P-202: StuI Polymorphism on the Androgen Receptor Gene in Women with Endometriosis

Background: Androgens have an anti-proliferative effect on endometrial cells. Human androgen receptor (AR) gene contains two polymorphic short tandem repeats of GGC and CAG, and a single-nucleotide polymorphism on exon 1 that is recognized by the restriction enzyme, StuI. Prior studies have shown that the lengths of the CAG and GGC repeats are inversely and linearly related to AR activity and a...

Mutant Profilin1 Aggregation in Amyotrophic Lateral Sclerosis: An in Vivo Biochemical Analysis

Introduction: Profilin1 (PFN1) is a ubiquitously expressed protein known for its function as a regulator of actin polymerization and dynamics. A recent discovery linked mutant PFN1 to Amyotrophic Lateral Sclerosis (ALS), which is a fatal and progressive motor neuron disease. We have also demonstrated that Gly118Val mutation in PFN1 is a cause of ALS, and the formation of aggregates containing m...
