Genome scanning of Corynebacterium glutamicum ATCC13032 revealed the presence of five different genes encoding enzymes belonging to three putative trehalose biosynthesis pathways (OtsAB, TreYZ, TreS). The function of the different pathways and of trehalose as an osmoprotectant was studied by characterizing several strains defective for individual trehalose(More)
In man the immunosuppressive drug Cyclosporine A (CsA) has been used successfully in organ transplantation and in the treatment of autoimmune disorders. The drug, however, causes side effects which occur mainly in the kidney but also in the liver. The mechanisms leading to the hepatic side effects are not yet fully understood. Because reactive oxygen(More)
OBJECTIVE To evaluate the relevance and necessity to account for the effects of population substructure on association studies under a case-control design in central Europe, we analysed three samples drawn from different geographic areas of Germany. Two of the three samples, POPGEN (n = 720) and SHIP (n = 709), are from north and north-east Germany,(More)
Primary cultures of heart myocytes from neonatal rats were used as an in vitro cardiac cell system to study the effects of the p-170kDa glycoprotein (Pgp) blockers PSC 833 [(3'-keto-Bmt1)-(Val2)-cyclosporine], verapamil and amiodarone on adriamycin cardiotoxicity. Immunostaining revealed the presence of Pgp in the cardiomyocytes. Adriamycin induced a(More)
Traditional opinion holds that patients with cystic fibrosis (CF) develop impaired glucose tolerance or diabetes due to insulinopenia caused by fibrosis of the pancreas. However, studies on the dynamics of insulin secretion and peripheral insulin action have yielded confliciting results. We studied 18 patients with CF (9 ♂, 9 ♀, age 15–29 years) and 17(More)
Next-generation sequencing (NGS) will likely facilitate a better understanding of the causes and consequences of human genetic variability. In this context, the validity of NGS-inferred single-nucleotide variants (SNVs) is of paramount importance. We therefore developed a statistical framework to assess the fidelity of three common NGS platforms. Using(More)
