ABC transporters constitute a family of evolutionarily highly conserved multispan proteins that mediate the translocation of defined substrates across membrane barriers. Evidence has accumulated during the past years to suggest that a subgroup of 12 structurally related "full-size" transporters, referred to as ABC A-subfamily transporters, mediates the(More)
We recently identified a novel ABC A subclass transporter, ABCA6, in human macrophages. Here, we report the molecular cloning of an additional ABC A subfamily transporter from macrophages denoted ABCA9. The identified coding sequence is 4.9 kb in size and codes for a 1624 amino acid protein product. In accordance with the proposed nomenclature, the novel(More)
This study aims to identify novel markers for gestational diabetes (GDM) in the biochemical profile of maternal urine using NMR metabolomics. It also catalogs the general effects of pregnancy and delivery on the urine profile. Urine samples were collected at three time points (visit V1: gestational week 8-20; V2: week 28±2; V3 10-16 weeks post partum) from(More)
Members of the human ABC transporter A subfamily have gained considerable attention based on the recent findings that ABCA1 and ABCR (ABCA4) cause familial HDL-deficiency syndromes and distinct forms of hereditary retinopathies, respectively. Here we report the complete cDNA and the genomic organization of ABCA2, another member of the human ABC A(More)
Quantitative reverse-transcription PCR (RT-qPCR) has become a major tool to better understand the biology and pathogenesis of bacteria. One prerequisite of valid RT-qPCR data is their proper normalization to stably expressed reference genes. To identify and evaluate reference genes suitable for normalization of gene expression data in Bacillus cereus group(More)
Here we report the cDNA cloning of a novel member of the ABC A transporter subfamily from human macrophages. The identified coding sequence is of 5.0 kb size and contains an open reading frame which encodes a 1617 amino acid polypeptide. Structurally, the putative ABC transporter protein product consists of two tandemly oriented subunits, each composed of a(More)
Central aspects of the cellular lipid trafficking mechanisms that occur during keratinocyte differentiation are still not well understood. In the past years, evidence has accumulated to suggest that members of the superfamily of adenosine triphosphate binding cassette (ABC) transporters are critically involved in the transmembrane transport of cellular(More)
The major rate-limiting enzyme for de novo cholesterol synthesis is 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR). HMGCR is sterically inhibited by statins, the most commonly prescribed drugs for the prevention of cardiovascular events. Alternative splicing of HMGCR has been implicated in the control of cholesterol homeostasis. The aim of this(More)
BACKGROUND Serum free light chain (SFLC) measurements have recently come into use as an aid for diagnosing monoclonal gammopathy. We evaluated SFLC measurements in combination with serum protein electrophoresis (SPE) and clinical information for diagnosing multiple myeloma (MM) in a hospital population. METHODS We measured SFLCs in 3818 sera received for(More)
BACKGROUND During the past years, we and others discovered a series of human ATP-binding cassette (ABC) transporters, now referred to as ABC A-subfamily transporters. Recently, a novel testis-specific ABC A transporter, Abca17, has been cloned in rodent. In this study, we report the identification and characterization of the human ortholog of rodent Abca17.(More)
