Gastric cancer is associated with NOS2 -954G/C polymorphism and environmental factors in a Brazilian population
(2010-06-17)
Background: Gastric cancer can progress from a chronic inflammation of the gastric mucosa resulting from Helicobacter pylori infection that activates the inflammatory response of the host. Therefore, polymorphisms in genes ...

(2010-01-11)
Abstract
Background
H. pylori seroprevalence in Brazilians varies and is dependent on socioeconomic status, sanitation conditions and ethnicity; furthermore, H. pylori is not ...

Gastric and small intestinal lesions after partial stomach resection with Billroth II or Roux-en-Y reconstruction in the rat
(Elsevier B. V., 1994)
The evolution and phenotypic expression of mucosal lesions of the gastric stump were investigated in male rats submitted to gastric resection with reconstruction by the Billroth II technique (BII with biliopancreatic reflux, ...
Upregulation of the APE1 and H2AX genes and miRNAs involved in DNA damage response and repair in gastric cancer
(2019-06-01)
Gastric cancer remains one of the leading causes of cancer-related death worldwide, and most of the cases are associated with Helicobacter pylori infection. This bacterium promotes the production of reactive oxygen species ...
Polymorphisms of the TLR2 and TLR4 genes are associated with risk of gastric cancer in a Brazilian population
(Baishideng Publ Grp Co Ltd, 2012-03-21)
AIM: To investigate toll-like receptor 2 (TLR2) -196 to -174 del, and TLR4 (+896A/G rs4986790 and +1196C/T rs4986791) polymorphisms at risk of chronic gastritis and gastric cancer in a Brazilian population and association ...
Tcf7l2 Rs7903146 Polymorphism Is Associated With Gastric Cancer: A Case-control Study In The Venezuelan Population
(Baishideng Publishing Group IncPleasanton, 2016)
Methylation pattern of THBS1, GATA-4, and HIC1 in pediatric and adult patients infected with helicobacter pylori
(2013-10-01)
Background: Helicobacter pylori infection is usually acquired in childhood and persists into adulthood if untreated. The bacterium induces a chronic inflammatory response, which is associated with epigenetic alterations ...
Okadaic acid toxin at sublethal dose produced cell proliferation in gastric and colon epithelial cell lines
(2013)
The aim of this study was to analyze the effect of Okadaic Acid (OA) on the proliferation of gastric and colon epithelial cells, the main target tissues of the toxin. We hypothesized that OA, at sublethal doses, activates ...
