The acyl-CoA dehydrogenases (ACDs) are a family of related enzymes that catalyze the alpha,beta-dehydrogenation of acyl-CoA esters. Two homologues active in branched chain amino acid metabolism have previously been identified. We have used expression in Escherichia coli to produce a previously uncharacterized ACD-like sequence (ACAD8) and define its(More)
PURPOSE Docetaxel is extensively metabolized by CYP3A4 in the liver but mechanisms by which the drug is taken up into hepatocytes remain poorly understood. We hypothesized that (i) liver uptake of docetaxel is mediated by the polymorphic solute carriers OATP1B1 and OATP1B3 and (ii) inherited genetic defects in this process may impair systemic drug(More)
Celastrol, a natural substance isolated from plant extracts used in traditional Chinese medicine, has been extensively investigated as a possible drug for treatment of cancer, autoimmune diseases, and protein misfolding disorders. Although studies focusing on celastrol's effects in specific cellular pathways have revealed a considerable number of targets in(More)
Nonsyndromic hearing impairment (NSHI) is a highly heterogeneous condition with more than eighty known causative genes. However, in the clinical setting, a large number of NSHI families have unexplained etiology, suggesting that there are many more genes to be identified. In this study we used SNP-based linkage analysis and follow up microsatellite markers(More)
The mitochondrial chaperonin heat shock protein 60 (Hsp60) assists the folding of a subset of proteins localized in mitochondria and is an essential component of the mitochondrial protein quality control system. Mutations in the HSPD1 gene that encodes Hsp60 have been identified in patients with an autosomal dominant form of hereditary spastic paraplegia(More)
Linkage studies suggest that chromosome 22q12-13 may contain one or more shared susceptibility genes for schizophrenia (SZ) and bipolar affective disorder (BPD). In a Faeroese sample, we previously reported association between microsatellite markers located at 22q13.31-qtel and both disorders. The present study reports an association analysis across five(More)
The bromodomain containing 1 (BRD1) gene has been implicated with transcriptional regulation, brain development, and susceptibility to schizophrenia and bipolar disorder. To advance the understanding of BRD1 and its role in mental disorders, we characterized the protein and chromatin interactions of the BRD1 isoforms, BRD1-S and BRD1-L. Stable human cell(More)
PURPOSE Dysfunction of the epidermal growth factor (EGF) complex is essential to the growth and development of many human tumors. Overexpression of the EGF receptor (EGFR) is a characteristic finding in a considerable number of solid tumors and often signalizes poor prognosis. There is a major disagreement among researchers about both the frequency and(More)
DNA transposon-based vectors have emerged as gene vehicles with a wide biomedical and therapeutic potential. So far, genomic insertion of such vectors has relied on the co-delivery of genetic material encoding the gene-inserting transposase protein, raising concerns related to persistent expression, insertional mutagenesis and cytotoxicity. This report(More)
Cells rely on efficient protein quality control systems (PQCs) to maintain proper activity of mitochondrial proteins. As part of this system, the mitochondrial chaperone Hsp60 assists folding of matrix proteins and it is an essential protein in all organisms. Mutations in Hspd1, the gene encoding Hsp60, are associated with two human inherited diseases of(More)
