PURPOSE Although the central role of the immune system for tumor prognosis is generally accepted, a single robust marker is not yet available. EXPERIMENTAL DESIGN On the basis of receiver operating characteristic analyses, robust markers were identified from a 60-gene B cell-derived metagene and analyzed in gene expression profiles of 1,810 breast cancer;(More)
Mutations in nuclear genes involved in mitochondrial DNA (mtDNA) maintenance cause a wide range of clinical phenotypes associated with the secondary accumulation of multiple mtDNA deletions in affected tissues. The majority of families with autosomal dominant progressive external ophthalmoplegia (PEO) harbour mutations in genes encoding one of three(More)
BACKGROUND The POLG1 gene encodes the catalytic subunit of DNA polymerase gamma, essential for mitochondrial DNA replication and repair. Mutations in POLG1 have been linked to a spectrum of clinical phenotypes, and may account for up to 25% of all adult presentations of mitochondrial disease. METHODS AND RESULTS We present 14 patients, with characteristic(More)
Metastasis from primary tumors remains a major problem for tumor therapy. In the search for markers of metastasis and more effective therapies, the tumor metabolome is relevant because of its importance to the malignant phenotype and metastatic capacity of tumor cells. Altered choline metabolism is a hallmark of cancer. More specifically, a decreased(More)
As already previously reported the EXCLI Journal closely cooperates with the Archives of Toxicology as a partner for articles focussing on basic and clinical research (Bolt, 2011; Bolt and Stewart, 2011). To give our readers an overview over current cutting-edge topics in toxicology we publish a compilation of brief 'key messages' from the most cited(More)
UNLABELLED Sodium valproate (VPA) is widely used throughout the world to treat epilepsy, migraine, chronic headache, bipolar disorder, and as adjuvant chemotherapy. VPA toxicity is an uncommon but potentially fatal cause of idiosyncratic liver injury. Rare mutations in POLG, which codes for the mitochondrial DNA polymerase γ (polγ), cause(More)
Sodium valproate (VPA) is widely used throughout the world to treat epilepsy, migraine, chronic headache, bipolar disorder, and as adjuvant chemotherapy. VPA toxicity is an uncommon but potentially fatal cause of idiosyncratic liver injury. Rare mutations in POLG, which codes for the mitochondrial DNA polymerase c (polc), cause Alpers-Huttenlocher syndrome(More)
Recently, epithelial to mesenchymal transition (EMT) has been shown to represent a feature of dedifferentiating hepatocytes in vitro. Three-dimensional soft collagen gels can antagonize but not completely abolish this effect. Hormonal additives to culture media are known to maintain differentiated hepatocyte functions. Therefore, we studied whether insulin(More)
