Identification of a T1D Susceptibility Gene

It is not known what causes type 1 diabetes (T1D), which affects over 1 million people in the U.S. alone. Each year, 30,000 young people in the U.S. develop this disease and depend on insulin injections thereafter. Because of the huge cost to the individual, the family, and to society in increased health care costs, it is important to find what makes these people susceptible. The...

Analysis of early mesothelial cell responses to Staphylococcus epidermidis isolated from patients with peritoneal dialysis-associated peritonitis

The major complication of peritoneal dialysis (PD) is the development of peritonitis, an infection within the abdominal cavity, primarily caused by bacteria. PD peritonitis is associated with significant morbidity, mortality and health care costs. Staphylococcus epidermidis is the most frequently isolated cause of PD-associated peritonitis. Mesothelial cells are integral to the...

Comparison of sequence variants in transcriptomic control regions across 17 mouse genomes

The laboratory mouse is the most widely used mammalian model organism in biomedical research, so a thorough annotation of functional variation in the mouse genome would be of significant value. In this study, we compared sequence variation in a comprehensive list of functional elements (e.g. promoters, enhancers and CTCF binding sites) across 17 inbred mouse strains. Sequences...

Definition of High-Risk Type 1 Diabetes HLA-DR and HLA-DQ Types Using Only Three Single Nucleotide Polymorphisms

Cao Nguyen Michael D. Varney Leonard C. Harrison Grant Morahan Evaluating risk of developing type 1 diabetes (T1D) depends on determining an individual's HLA type, especially of the HLA DRB1 and

A novel mutation causing nephronophthisis in the Lewis polycystic kidney rat localises to a conserved RCC1 domain in Nek8

BackgroundNephronophthisis (NPHP) as a cause of cystic kidney disease is the most common genetic cause of progressive renal failure in children and young adults. NPHP is characterized by abnormal and/or loss of function of proteins associated with primary cilia. Previously, we characterized an autosomal recessive phenotype of cystic kidney disease in the Lewis Polycystic Kidney...

Status and access to the Collaborative Cross population

The Collaborative Cross (CC) is a panel of recombinant inbred lines derived from eight genetically diverse laboratory inbred strains. Recently, the genetic architecture of the CC population was reported based on the genotype of a single male per line, and other publications reported incompletely inbred CC mice that have been used to map a variety of traits. The three breeding...

A Susceptibility Allele From a Non-Diabetes-Prone Mouse Strain Accelerates Diabetes in NOD Congenic Mice

The clinical course of steroid-sensitive childhood nephrotic syndrome is associated with a functional IL12B promoter polymorphism

Background. Steroid-sensitive nephrotic syndrome (NS) of childhood is the most common glomerular disease in children. The type and duration of response to corticosteroid therapy are used for clinical classification, and especially patients with steroid dependence often have a complicated course, requiring intensified immunosuppressive treatment. Its cause is still unknown...
