Stress evokes an integrated neuroendocrine response perturbing the homeostasis of different physiological systems. In contrast to well established physiologica linteractions between neuroendocrine and immune systems during chronic stress, there has been relatively little information on the effects of psychological stress on erythroid cells. Since(More)
The gene and protein expression profiles in myeloproliferative neoplasms (MPNs) may reveal gene and protein markers of a potential clinical relevance in diagnosis, treatment and prediction of response to therapy. Using cDNA microarray analysis of 25,100 unique genes, we studied the gene expression profile of CD34+ cells and granulocytes obtained from(More)
The aim of our study was to investigate HER-2 and TOP2A gene status and their correlation with Bcl-2, p53, Ki67, ssDNA, and clinicopathological parameters in four molecular subtypes of breast cancer. Seventy-four paraffin-embedded samples are immunohistochemically studied for the expression of estrogen receptor (ER), progesterone receptor (PR), HER-2, p53,(More)
The aim of our study was to investigate the appearance, density and distribution of ghrelin cells and GHS-R1a and GHS-R1b in the human stomach and duodenum during prenatal and early postnatal development. We examined chromogranin-A and ghrelin cells in duodenum, and GHS-R1a and GHS-R1b expression in stomach and duodenum by immunohistochemistry in embryos,(More)
INTRODUCTION Hydroxycarbamide, used in therapy of hemoglobinopathies, enhances nitric oxide (NO) production both in primary human umbilical vein endothelial cells (HUVECs) and human bone marrow endothelial cell line (TrHBMEC). Moreover, NO increases gamma-globin and fetal hemoglobin levels in human erythroid progenitors. OBJECTIVE In order to find out(More)
Increased angiogenesis in BCR-ABL1 negative myeloproliferative neoplasms (MPNs) has been recognized, but its connection with clinical and molecular markers needs to be defined. The aims of study were to (1) assess bone marrow (BM) angiogenesis measured by microvessel density (MVD) using CD34 and CD105 antibodies; (2) analyze correlation of MVD with plasma(More)
It has been shown that angiogenesis and inflammation play an important role in development of most hematological malignancies including the myeloproliferative neoplasm (MPN). The aim of this study was to investigate and correlate the levels of key angiogenic molecules such as hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF)(More)
BACKGROUND/AIM The purpose of this study was to investigate proliferation and differentiation markers in colorectal adenocarcinoma and their correlation with clinicopathological factors. MATERIALS AND METHODS Samples were collected from 38 patients with colorectal adenocarcinoma and 10 healthy controls. E-cadherin, carcinoembryonic antigen (mCEA), cyclin(More)
PURPOSE The purpose of this study was to examine the gene expression profile of granulocyte colony stimulating factor (G-CSF)-mobilized peripheral blood (mPB)-derived progenitors, used in transplantation. METHODS We correlated gene expression patterns of highly enriched steady-state peripheral blood (PB)- and mPB-derived CD71+ cells by microarray and(More)
