Mutations in the oncogenes KRAS and BRAF have been identified as prognostic factors in patients with colorectal diseases and as predictors of negative outcome in epidermal growth factor receptor-targeted therapies. Therefore, accurate mutation detection in both genes, KRAS and BRAF, is of increasing clinical relevance. We aimed at optimizing allele-specific(More)
OBJECTIVES Recently, a significant impact of a new locus on chromosome 1p13.3 on serum LDL (low-density lipoprotein) cholesterol and clinical events of coronary artery disease (CAD) was described. Potential associations between variants on this locus and angiographically characterized coronary atherosclerosis are unknown. We therefore aimed at investigating(More)
BACKGROUND Coronary artery disease (CAD) shares common risk factors with type 2 diabetes (T2DM). Variations in the transcription factor 7-like 2 (TCF7L2) gene, particularly rs7903146, increase T2DM risk. Potential links between genetic variants of the TCF7L2 locus and coronary atherosclerosis are uncertain. We therefore investigated the association between(More)
The newly discovered metastasis-associated in colon cancer-1 (MACC1) gene is a key regulator of the HGF/MET pathway. Deregulation of HGF/MET signaling is reported as a prognostic marker for tumorigenesis, early stage invasion, and metastasis. High expression levels of MACC1 have been associated with colon cancer metastasis and reduced survival. Potential(More)
BACKGROUND Deregulation of hepatocyte growth factor (HGF)/mesenchymal-epithelial transition factor (MET) signalling has been associated with poor clinical outcome in breast cancer and other cancers. The recently discovered metastasis-associated in colon cancer-1 (MACC1) gene is a key regulator of the HGF/MET pathway. Potential links between genetic variants(More)
Hypoxia in adipose tissue is suggested to be involved in the development of a chronic mild inflammation, which in obesity can further lead to insulin resistance. The effect of hypoxia on gene expression in adipocytes appears to play a central role in this inflammatory response observed in obesity. However, the global impact of hypoxia on transcriptional(More)
Insulin-like growth factor 1 (IGF-1) stimulates mitosis and inhibits apoptosis. High circulating IGF-1 levels are linked with an increased risk of colorectal and breast cancer. Recently, IGF-1 single nucleotide polymorphisms (SNPs), especially variant rs2946834, have been associated with poor clinical outcome in patients with colorectal cancer. In the(More)
BACKGROUND Fetuin-A (AHSG) has been proposed as a new cardiovascular risk factor. Fetuin-A levels as well as AHSG single nucleotide polymorphisms (SNPs) have been associated with intima media thickness and incident vascular events, respectively. However, the association between AHSG variants and angiographically determined coronary artery disease (CAD) has(More)
3594 Background: The newly discovered metastasis-associated in colon cancer-1 (MACC1) gene is a key regulator of the HGH/met pathway. Deregulation of HGH/met signalling is reported as prognostic marker for early stage invasion, tumorigenesis, and metastasis. High expression levels of MACC1 have been associated with colon cancer metastasis and reduced 5-year(More)
6585 Background: The revised World Health Organization (WHO) diagnostic criteria for the diagnosis of polycythemia vera (PV) and essential thrombocythemia (ET) now implement detection of JAK2 V617F mutation. Patients with these myeloproliferative neoplasms (MPNs) are at increased risk towards atherothrombotic complications. Therefore, diagnosis of PV or ET(More)
