Esophageal cancer (EC) is the sixth leading cause of cancer-associated death worldwide and the incidence and mortality in China are the highest. The single nucleotide polymorphisms (SNPs) related to microRNAs could lead to alteration in microRNA expression and contribute to the susceptibility of cancer. To evaluate the association between microRNA-related(More)
Lyme disease, the most common vector-borne disease in the United States, is caused by a tick-borne infection with Borrelia burgdorferi. Currently, Ohio is considered by the Centers for Disease Control and Prevention (CDC) to be non-endemic for Lyme disease. The low incidence of Lyme disease in this state was largely attributed to the absence of the(More)
The structure of a new O-polysaccharide from Escherichia coli O86:K62:B7 was determined using NMR and methylation analysis. The structure is as follows: [carbohydrate: see text]. Comparison with the previously published structure from E. coli O86:K2:H2 revealed that the O-polysaccharides from these two E. coli O86 serotypes share the same branched(More)
We previously showed that alpha-synuclein (α-Syn), a protein implicated in the pathogenesis of several neurodegenerative diseases, is a microtubule-associated protein (MAP), facilitating the polymerization of tubulin into microtubules. Therefore, we hypothesized that α-Syn might promote neurite outgrowth, a process that requires microtubule assembly. To(More)
Computational evaluation of protein-DNA interaction is important for the identification of DNA-binding sites and genome annotation. It could validate the predicted binding motifs by sequence-based approaches through the calculation of the binding affinity between a protein and DNA. Such an evaluation should take into account structural information to deal(More)
X-ray repair cross-complementing group 1 gene (XRCC1) has been implicated in risk for lung cancer. However, the results from different studies remain controversial. In this meta-analysis, we have assessed 44 published case–control studies regarding associations of lung cancer risk with three common polymorphisms, codon 194, codon 280 and codon 399, and −77(More)
C. elegans has proven to be an excellent organism in which to model human neurodegenerative disease.(1) (-) (7) The worm's simple nervous system, lineage, and neural maps, easily scored movement phenotypes, and robust forward and reverse genetics make it optimal for studying age-dependent processes on a reasonable time scale. A popular approach has been the(More)
Polyketides are important bioactive natural products biosynthesized by bacteria, fungi, and plants. The enzymes that synthesize polyketides are collectively referred to as polyketide synthases (PKSs). Because many of the natural hosts that produce polyketides are difficult to culture or manipulate, establishing a universal heterologous host that is(More)
