The health burden of cancer is increasing in China, with more than 1·6 million people being diagnosed and 1·2 million people dying of the disease each year. As in most other countries, breast cancer is now the most common cancer in Chinese women; cases in China account for 12·2% of all newly diagnosed breast cancers and 9·6% of all deaths from breast cancer(More)
As a metropolis with rapid social and economic development over the past three decades, Shanghai has a breast cancer incidence that surpasses all other cancer registries in China. In order to estimate the regular changing patterns of female breast cancer in urban Shanghai, population-based incidence data from 1975 to 2004 were studied. In addition, a(More)
The association between single-nucleotide polymorphisms (SNPs) in the interleukin-10 (IL-10) gene promoter and breast cancer risk is still ambiguous. We here performed a meta-analysis based on the evidence currently available from the literature to make a more precise estimation of the relationship between two genetic variants in the IL-10 gene promoter,(More)
The association between single-nucleotide polymorphisms (SNPs) in the COX-2 gene and breast cancer risk is still ambiguous. We here try to derive a more precise estimation of the relationship by performing a meta-analysis based on currently available evidence from literature. More than 15 SNPs have been studied, and the most studied genetic variants were(More)
The association between a single-nucleotide polymorphism (SNP) −174G > C (rs1800795) located in the IL-6 gene promoter and breast cancer risk is still controversial and ambiguous. We performed in this study a more precise estimation of the relationship by meta-analyzing the currently available evidence from literature. A total of 11 publications containing(More)
To the Editor, The aim of case-control association studies is to find genetic variants in the human genome that influence common diseases and traits. The Human Genome and HapMap projects have added fresh impetus to this goal by cataloguing the updated genetic data. Although most single-nucleotide polymorphisms (SNPs) must be quasineutral, a proportion of(More)
A single-nucleotide polymorphism (SNP) in the 5′-untranslated region (UTR) of RAD51, 135G>C (rs1801320), was reported to be associated with an increased risk of breast cancer among BRCA2 as well as BRCA1 carriers. A few studies have also investigated the genetic contribution of RAD51 135G>C to the risk of sporadic breast cancers or breast cancer in(More)
The estrogen signal is mediated by the estrogen receptor (ER). The specific role of ER-beta, a second ER, in breast carcinogenesis is not known. A number of association studies have been carried out to investigate the relationship between polymorphic sites in the ESR2 gene and breast cancer risk, however, the results are inconsistent. We searched PubMed,(More)
MicroRNAs (miRNAs) have been shown to play critical roles in regulating the progress of leukemia. We performed miRNA expression profile in six Chinese patients with chronic lymphocytic leukemia (CLL), and in peripheral B cells from pooled 30 healthy donors, using a platform containing 866 human miRNAs. The most frequent changes in miRNAs in CLL cells(More)
