Helicobacter pylori (H. pylori) infection has been associated with gastric disorders. The situation of H. pylori infection in China-where a high prevalence of H. pylori infection, a high incidence of gastric cancer, and widespread resistance to clarithromycin, metronidazole, and levofloxacin exist-is quite different from that in Western countries. In order(More)
Phosphorylation of H2AX at Ser 139 (γH2AX) is a biomarker of DNA double-strand breaks (DSBs). The present study aimed to explore the association between γH2AX levels and gastric pathology and Helicobacter pylori (H. pylori) infection. Gastric biopsies were obtained from 302 H. pylori-negative and -positive patients, including those with chronic gastritis(More)
Filamin A interacting protein 1-like (FILIP1L), which was reported to be consistently absent in ovarian cancer cell lines, has been identified to hold therapeutic potential for inhibiting tumor growth, and its COOH-terminal truncation mutant (FILIP1LΔC103) was found to be more potent than the wild-type. The use of polymeric nanoparticles to deliver(More)
Phosphorylation of PTEN at residues Ser380/Thr382/383 leads to loss of phosphatase activity and tumor suppressor function. Here, we found that phosphorylation of PTEN at residues Ser380/Thr382/383 was increased with gastric carcinogenesis, and more importantly, Helicobacter pylori was a trigger of this modification in chronic non-atrophic gastritis. H.(More)
OBJECTIVES We evaluate the efficacy of concomitant therapy for Helicobacter pylori infection and the associated factors that influence it in China, where it has not previously been investigated. METHODS In this prospective study, 374 consecutive patients with H. pylori infection were randomly assigned to 10 day regimens of concomitant therapy with(More)
Human PNAS-4 (hPNAS-4), as a pro-apoptotic gene, can inhibit tumor growth when overexpressed in some malignant cells. Poly (lactic-co-glycolic acid) (PLGA) was used as a gene transfer vector due to the advantage of sustained release, nontoxicity and biodegradability. In this study, we aimed to investigate the effect of PLGA nanoparticles encapsulating(More)
BACKGROUND Some studies have suggested an association between Helicobacter pylori infection and the risk of stroke, but the relationship remains controversial. The aim of this study was to obtain a more comprehensive estimate of H. pylori on the risk of stroke by performing a meta-analysis. METHODS A computerized search of PubMed, EMBASE, and the Cochrane(More)
HSulf-1 (heparan sulfate 6-O-endosulfatase 1), a commonly downregulated gene in the majority of ovarian cancer cell lines, has been identified to play an important role in regulating tumorigenesis. Our previous studies demonstrated that HSulf-1 could inhibit angiogenesis and tumorigenesis in vivo. The employment of polymeric nanoparticles to deliver(More)
The HSulf-1 (heparan sulfate 6-O-endosulfatase 1) gene is an important element that modulates the sulfation status of heparan sulfate proteoglycans (HSPGs), leading to the interference of HSPG-related signal transduction pathways. HSulf-1 plays a key role in regulating cell proliferation, tumorigenesis and angiogenesis.(More)
Helicobacter pylori (H. pylori) is an ancient and persistent inhabitant of the human stomach that is closely linked to the development of gastric cancer (GC). . Emerging evidence suggests that H. pylori strain interactions with gastric epithelial cells subvert the best- characterized p53 tumour suppressor pathway. A high prevalence of p53 mutations is(More)
