BACKGROUND & AIMS Inflammatory bowel diseases (IBD) are becoming more common in Asia, but epidemiologic data are lacking. The Asia-Pacific Crohn's and Colitis Epidemiology Study aimed to determine the incidence and phenotype of IBD in 8 countries across Asia and in Australia. METHODS We performed a prospective, population-based study of IBD incidence in(More)
Chronic inflammation is the hallmark of the pathogenesis of Helicobacter pylori-induced gastric cancer. Interleukin (IL)-17A and IL-17F are inflammatory cytokines expressed by a novel subset of CD4+ Th cells and play critical function in inflammation and probably in cancer. We conducted a case-control study including 1,010 gastric cancer patients and 800(More)
BACKGROUND The role of Epstein-Barr virus (EBV) infection in gastric carcinogenesis remains largely unknown. The authors studied the effects of zinc finger E-box binding factor 1 (ZEB1) on latent-lytic switch of EBV infection in gastric cancer and explored the importance of EBV in gastric carcinogenesis. METHODS Loss or gain of ZEB1 function was obtained(More)
OBJECTIVE The rising incidence of inflammatory bowel disease in Asia supports the importance of environmental risk factors in disease aetiology. This prospective population-based case-control study in Asia-Pacific examined risk factors prior to patients developing IBD. DESIGN 442 incident cases (186 Crohn's disease (CD); 256 UC; 374 Asians) diagnosed(More)
UNLABELLED Today, the causal relationship between inflammation and gastric cancer is more widely accepted. Genetic variations in inflammation-related genes especially cytokines and their receptors, were thought to partly determine the outcome of Helicobacter pylori (H. pylori) infection and progression of gastric lesions. Interleukin 23 receptor (IL23R), as(More)
OBJECTIVES The association of interleukin-1B (IL-1B)-511 polymorphism with gastric cancer is still controversial, and the association of IL-1B-511 polymorphism with subtypes of gastric cancer is still largely unknown. We investigated whether the association between IL-1B-511 polymorphism and gastric cancer risk varies by clinically important tumor(More)
BACKGROUND & AIMS The incidence of inflammatory bowel disease (IBD) is increasing in Asia, but little is known about disease progression in this region. The Asia-Pacific Crohn's and Colitis Epidemiology Study was initiated in 2011, enrolling subjects from 8 countries in Asia (China, Hong Kong, Indonesia, Sri Lanka, Macau, Malaysia, Singapore, and Thailand)(More)
BACKGROUND AND AIMS The incidence of inflammatory bowel disease (IBD) is increasing in China with urbanization and socioeconomic development. There is however a lack of prospective, population-based epidemiology study on IBD in China. The aim of the study is to define the incidence and clinical characteristics of IBD in a developed region of Guangdong(More)
We previously showed that BCL6B acts as a tumor suppressor in gastric cancer and up to 66% gastric cancer patients have promoter hypermethylation in tumor tissues. We aimed to evaluate the feasibility of detecting BCL6B methylation in plasma DNA as a potential biomarker for gastric cancer. Hypermethylation of the CpG islands in BCL6B promoter was detected(More)
Angiogenesis is essential for tumor growth. Hepatocellular carcinoma (HCC) is characterized by hypervascularity; high levels of angiogenesis are associated with poor prognosis and a highly invasive phenotype in HCC. Up-regulated gene-4 (URG4), also known as upregulator of cell proliferation (URGCP), is overexpressed in multiple tumor types and has been(More)
