Background: Nasopharyngeal carcinoma (NPC) is especially prevalent in southeast Asia and southern China, but its molecular mechanisms remain poorly characterized. DNA methylation is associated with initiation and progression of tumors, including NPC. Through a genome-wide DNA methylation screening approach, we discovered ZNF154, but its methylation status and roles in NPC have not been investigated. Methods: The methylation status of ZNF154 in NPC was detected with Methylation specific-PCR (MSP) and Quantitative Sequenom MassARRAY...

BACKGROUND: Gene polymorphisms at microRNA-binding sites (poly-miRTS) may affect gene transcription and expression through miRNA regulation, which is associated with cancer susceptibility, sensitivity to chemotherapy and prognosis. This study investigated the association between poly-miRTS of Ara-C/anthracycline metabolic pathways genes and the outcome of acute myeloid leukemia (AML) in Chinese patients after Ara-C-based chemotherapy. METHODS: A total of 17 poly-miRTS were selected from the SNPinfo Web Server and genotyped in 206 Chinese Han non-FAB-M3 AML patients using the SEQUENOM Mass-ARRAY system...

BACKGROUND: Depression is one of the most prevalent psychiatric disorders, and in older persons is associated with high levels of comorbidity and under-treatment. Dysfunction of the hypothalamic-pituitary-adrenal (HPA) stress axis is consistently observed in the older population as well as depressed patients, with the angiotensin converting enzyme (ACE) a key regulator of the stress response. Epigenetic regulation of ACE may play an important role in HPA axis (dys)regulation. OBJECTIVE: To investigate ACE promoter methylation as a biomarker of late-life depression, and its association with genetic variation and cortisol secretion...

BACKGROUND: Galectin-3 plays an important role in modulating cardiac inflammation and fibrosis. It also takes part in the pathways underlying cardiac remodeling. Therefore, LGALS3 gene, encoding galectin-3 protein, is a promising candidate for the genetic study of dilated cardiomyopathy (DCM). To date, there has been no research evaluating the association between LGALS3 gene polymorphisms and the susceptibility and prognosis of DCM. METHODS AND RESULTS: Genotyping of 4 single nucleotide polymorphisms (SNPs) in the LGALS3 gene, which were reported to be functional in the literature, was performed in 279 unrelated clinically diagnosed DCM patients and 363 apparently healthy controls from Northern Han Chinese population using iPLEX SNP Genotyping analysis on a Sequenom MassARRAY System...

BACKGROUND: The etiology of neurodegenerative disease remains unclear. Recently, SNP rs11868035, located in an intron of the sterol regulatory element binding factor (SREBF1) gene, was found to be associated with Parkinson's disease (PD) in a large European population in a genome-wide association study. To examine the possible genetic association of rs11868035 with sporadic PD, sporadic amyotrophic lateral sclerosis (ALS) and multiple system atrophy (MSA) in a Chinese population, we conducted this large case-control study...

Acute coronary syndrome (ACS) is a common disease with high mortality and morbidity rates. The methylation status of blood DNA may serve as a potential early diagnosis and prevention biomarker for numerous diseases. The present study was designed to explore novel genome-wide aberrant DNA methylation patterns associated with ACS. The Infinium HumanMethylation450 assay was used to examine genome-wide DNA methylation profiles in 3 pairs of ACS and control group samples. Epigenome-wide DNA methylation, genomic distribution, Gene Ontology (GO) term and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed...

Alzheimer's disease (AD) is the most common neurodegenerative disease characterized by progressive cognitive decline. It can be divided into familial AD (FAD) and sporadic AD (SAD) based on the family history. Recently dysregulation of cholesterol homeostasis has been implicated in the development of late-onset AD. ATP-binding cassette transporter A7 (ABCA7) gene, regulating the transport of cholesterol, has been recently identified as a susceptible gene of AD by several large genome-wide association studies...

Multiple genetic and environmental factors together contribute to the risk of IgA nephropathy (IgAN). MPHOSPH6 play an important role in the recruitment of the exosome to the pre-rRNA. However, to date, little information is found about the association between MPHOSPH6 polymorphisms and the IgAN risk. In this case-control study, we genotyped five single nucleotide polymorphisms (SNPs) in MPHOSPH6 gene in 416 IgAN cases and 495 controls using Sequenom Mass-ARRAY technology and evaluated their association with IgAN using the χ2 and genetic model analysis...

IgA nephropathy (IgAN) is the most common form of primary glomerulonephritis worldwide, but etiology and pathogenesis continue to be poorly understood. Polymorphisms in the cytokine genes may play a role in the etiology and pathogenesis of IgAN. The incidence of different between diverse ethnic groups suggested important genetic influences on its pathogenesis. We genotype 10 single nucleotide polymorphisms (SNPs) in IL-1B and IL-6 gene using Sequenom Mass-ARRAY technology from 417 IgAN patients and 463 healthy controls of the Chinese Han population...
