The function of the majority of genes in the mouse and human genomes remains unknown. The mouse embryonic stem cell knockout resource provides a basis for the characterization of relationships between genes and phenotypes. The EUMODIC consortium developed and validated robust methodologies for the broad-based phenotyping of knockouts through a pipeline(More)
Mutations in the insulin (INS) gene may cause permanent neonatal diabetes mellitus (PNDM). Ins2 mutant mouse models provided important insights into the disease mechanisms of PNDM but have limitations for translational research. To establish a large animal model of PNDM, we generated INS(C94Y) transgenic pigs. A line expressing high levels of INS(C94Y) mRNA(More)
PURPOSE The purpose of the study was the characterization of the novel small-eye mutant Aey12 in the mouse. METHODS The eyes of the mutants were described morphologically and histologically and by in situ hybridization. RESULTS The homozygotes were viable and fully fertile, which identifies Aey12 as a new microphthalmia phenotype in the mouse, different(More)
Balhimycin, produced by the actinomycete Amycolatopsis balhimycina DSM5908, is a glycopeptide antibiotic highly similar to vancomycin, the antibiotic of 'last resort' used for the treatment of resistant Gram-positive pathogenic bacteria. Partial sequence of the balhimycin biosynthesis gene cluster was previously reported. In this work, cosmids which overlap(More)
Actinoplanes friuliensis produces the lipopeptide antibiotic friulimicin. This antibiotic is active against gram-positive bacteria such as multiresistant Enterococcus and Staphylococcus strains. It consists of 10 amino acids that form a ring structure and 1 exocyclic amino acid to which an acyl residue is attached. By a reverse genetic approach,(More)
The mouse inbred line C57BL/6J is widely used in mouse genetics and its genome has been incorporated into many genetic reference populations. More recently large initiatives such as the International Knockout Mouse Consortium (IKMC) are using the C57BL/6N mouse strain to generate null alleles for all mouse genes. Hence both strains are now widely used in(More)
PURPOSE O377 was identified as a new dominant cataract mutation in mice after radiation experiments. The purpose of this study was to genetically characterize the mutation and to analyze its biological consequences. METHODS Linkage analysis of the O377 mouse mutant was performed; candidate genes including Crybb2 were sequenced. The authors analyzed eyes(More)
Under the label of the German Mouse Clinic (GMC), a concept has been developed and implemented that allows the better understanding of human diseases on the pathophysiological and molecular level. This includes better understanding of the crosstalk between different organs, pleiotropy of genes, and the systemic impact of envirotypes and drugs. In the GMC,(More)
PURPOSE To study susceptibility to glaucoma injury as it may be affected by mutations in ocular connective tissue components. METHODS Mice homozygous for an N-ethyl-N-nitrosourea induced G257D exchange (Gly to Asp) missense mutation (Aca23) in their collagen 8A2 gene were studied to measure intraocular pressure (IOP), axial length and width, number of(More)
The corticotropin-releasing hormone (CRH) and its type 1 receptor (CRHR1) play a central role in coordinating the endocrine, autonomic, and behavioral responses to stress. A prerequisite to functionally dissect the complexity of the CRH/CRHR1 system is to unravel the identity of CRHR1-expressing neurons and their connectivities. Therefore, we used a knockin(More)
