BACKGROUND Increasing evidences show that beyond its role in coagulation, endothelial protein C receptor (EPCR) interferes with carcinogenesis. Pro-carcinogenic effects of EPCR were linked with a raised generation of activated protein C (aPC) and anti-apoptotic signalling. This study was carried out to analyze the expression, cell surface exposition, and(More)
The M-type phospholipase A2 receptor (PLA2R1) plays a crucial role in several signaling pathways and may act as tumor-suppressor. This study examined the expression and methylation of the PLA2R1 gene in Jurkat and U937 leukemic cell lines and its methylation in patients with myelodysplastic syndrome (MDS) or acute leukemia. Sites of methylation of the(More)
Epigenetic changes provide a frequent mechanism for transcriptional silencing of genes in cancer cells. We previously established that epigenetic mechanisms are important for control of group IIA phospholipase A(2) (PLA2G2A) gene transcription in human DU-145 prostate cells. In this study, we analyzed the involvement of such mechanisms in the regulation of(More)
It is well-known that the plasma level of group IIA phospholipase A2 (sPLA2-IIA) is increased in patients with malignant diseases, but whether the up-regulated enzyme expression is directly related to tumorigenesis or a consequence of tumor-associated inflammation remains unresolved. In this study we analyzed circulating levels of sPLA2-IIA, C-reactive(More)
It has recently been proposed that the M-type phospholipase A2 receptor (PLA2R1) acts as a tumour suppressor in certain malignancies including mammary cancer. Considering that DNA methylation is an important regulator of gene transcription during carcinogenesis, in the current study we analyzed the PLA2R1 expression, PLA2R1 promoter methylation, and(More)
Serum amyloid A (SAA), secreted group IIA phospholipase A2 (sPLA2-IIA), and C-reactive protein (CRP) are acute-phase proteins whose serum concentrations increase not only during inflammatory disorders, but also in the course of malignant diseases. In this study we analyzed serum levels of these inflammatory markers along with prostate-specific antigens(More)
Secreted phospholipases A2 (sPLA2) are suggested to play an important role in inflammation and tumorigenesis. Different mechanisms of epigenetic regulation are involved in the control of group IIA, III and X sPLA2s expression in cancer cells, but group V sPLA2 (GV-PLA2) in this respect has not been studied. Here, we demonstrate the role of epigenetic(More)
