The severe environmental stresses of the Arctic may have promoted unique soil bacterial communities compared with those found in lower latitude environments. Here, we present a comprehensive analysis of the biogeography of soil bacterial communities in the Arctic using a high resolution bar-coded pyrosequencing technique. We also compared arctic soils with(More)
A balanced fertilization can increase crop yields partly due to stimulated microbial activities and growths. In this study, we investigated arbuscular mycorrhizal fungi (AMF) in arable soils to determine the optimal practices for an effective fertilization. We used pyrosequencing-based approach to study AMF diversity, as well as their responses to different(More)
Single-nucleotide polymorphisms in microRNAs (miRNAs) may alter miRNA expression levels or processing and, thus, may contribute to cancer development. We hypothesized that miRNA-196a2 polymorphism is associated with risk of colorectal cancer (CRC). In a case-control study of 573 patients with CRC and 588 cancer-free controls frequency matched by age and(More)
MicroRNAs (miRNAs) are a family of endogenous, small, noncoding RNA molecules that involved in a wide range of biological processes including differentiation, proliferation, and apoptosis. A polymorphism G>C (rs2910164) is located in the stem region opposite to the mature miR-146a sequence. In our study, we investigated whether rs2910164 is associated with(More)
BACKGROUND MicroRNAs (miRNAs) are a family of endogenous, small and noncoding RNAs that negatively regulate gene expression by suppressing translation or degrading mRNAs. Recently, many studies investigated the association between hsa-miR-196a2 rs11614913 polymorphism and cancer risk, which showed inconclusive results. METHODOLOGY/PRINCIPAL FINDINGS We(More)
BACKGROUND MicroRNAs (miRNAs) are a class of small non-coding RNAs to regulate cell differentiation, proliferation, development, and apoptosis. The single nucleotide polymorphism (SNP) rs895819 is located at the terminal loop of pre-miR-27a. Here, we aimed to investigate whether SNP rs895819 was associated with the development of renal cell cancer (RCC) in(More)
To characterize the location of glycolytic enzymes (GEs) in intact human erythrocytes, freshly drawn blood was fixed and stained with Abs to GAPDH, aldolase, phosphofructokinase (PFK), pyruvate kinase (PK), lactate dehydrogenase (LDH), carbonic anhydrase II, Hb, and band 3 (AE1). Confocal microscopy revealed that in cells where band 3 displays its expected(More)
Continent-scale biogeography has been extensively studied in soils and marine systems, but little is known about biogeographical patterns in non-marine sediments. We used barcode pyrosequencing to quantify the effects of local geochemical properties and geographic distance for bacterial community structure and membership, using sediment samples from 15(More)
OBJECTIVE Adiponectin (AdipoQ) plays an important role in the pathogenesis of diabetes mellitus and is considered as an important candidate gene for type 2 diabetes mellitus (T2DM). So far, there have been many studies to investigate the association between the adiponectin polymorphisms and T2DM risk. However, the results are conflicting. To derive a more(More)
Human oxoguanine glycosylase 1 (hOGG1) is a DNA repair enzyme, which plays important roles in the base excision repair (BER) pathway. Several studies reported a common polymorphism Ser326Cys (rs1052133) in hOGG1, which conferred the susceptibility of bladder cancer. We hypothesized that the polymorphism is associated with risk of bladder cancer in a Chinese(More)
