Pathophysiological processes associated with disturbances in cell and tissue oxidative homeostasis, are associated with self-catalyzed process of lipid peroxidation. The end products of lipid peroxidation are reactive aldehydes such as 4-hydroxy-2-nonenal (HNE), acting as "second messengers of free radicals." Although reactive aldehydes were first(More)
NF2/Merlin was first identified through its association with neurofibromatosis type 2 (NF2). However, accumulating evidence suggests a more general involvement in tumorigenesis and, in particular, a broader role in tumor suppression. The aim of this study was to examine NF2/Merlin involvement in sporadic colorectal cancer. This study is the first to examine(More)
AIM To assess whether alterations in the K-ras, p53, and DPC4 genes are present in pancreatitis, a potential precancerous condition that can progress to pancreatic adenocarcinoma. To investigate the alterations occurring at hot spots of K-ras (exon 1), p53 (exons 5 and 7), and DPC4 (exons 8, 10 and 11). METHODS In 10 patients with acute and 22 with(More)
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) secrete biogenic amines, hormones and growth factors, tumor necrosis factor-alpha (TNF-alpha) being one of them. As the expression of TNF-alpha is mostly regulated at the transcriptional level, its promoter polymorphisms have been intensively studied as a potential determinant of TNF-alpha production(More)
BACKGROUND Human FHIT (fragile histidine triad) gene is highly conserved gene homologous to a group of genes identified in prokaryotes and eukaryotes. Loss of FHIT function may be important in the development and/or progression of various types of cancer. MATERIALS AND METHODS We undertook a clinical study to analyze the relation between aberrant function(More)
Type 1 diabetes mellitus (TIDM) is an autoimmune disease characterized by the destruction of pancreatic p cells. Tumor necrosis factor (TNF) is a pleotropic cytokine with potent immunomodulatory and inflammatory activity. Association studies of TNF polymorphisms and type 1 diabetes (TIDM) frequently demonstrated TNF involvement with TIDM. Although TNF may(More)
Cerebral palsy (CP) is a nonprogressive motor disorder caused by white matter damage in the developing brain. Recent epidemiological and clinical data suggest intrauterine infection/inflammation as the most common cause of preterm delivery and neonatal complications, including CP. Cyclooxygenases are key enzymes in the conversion of arachidonic acid to(More)
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are highly vascularized neoplasms, capable of synthethisizing VEGF-A, a key mediator of angiogenesis. In pancreatic neuroendocrine tumors (pNETs) VEGF expression is higher in benign and low-grade tumors and associated with good prognosis (neuroendocrine paradox) while the VEGF role in gastrointestinal(More)
Although previously considered rare, recent epidemiological studies have revealed that the incidence (3.6/100,000) and prevalence (35/100,000) of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) has increased over the past few decades. Despite the progress in the understanding of GEP-NET molecular biology, there is still little advance in the early(More)
