Abstract Personalized medical care focuses on prediction of disease risk and response to medications. To build the models, access both large-scale genomic resources human genetic studies is required. The Taiwan Biobank (TWB) has generated high-coverage, whole-genome sequencing data from 1492 individuals genome-wide SNP 103,106 Han Chinese ancestry using custom arrays. Principal components analysis genotyping showed that full range variation was found in cohort. arrays also include thousands...

Long-term arsenic exposure is associated with an increased risk of vascular diseases including ischemic heart disease, cerebrovascular and carotid atherosclerosis. The pathogenic mechanisms atherogenicity are not completely clear. A fundamental role for inflammation in atherosclerosis its complications has become appreciated recently. To investigate molecular targets inflammatory pathway possibly involved arsenic-associated atherosclerosis, we conducted exploratory study using cDNA...

Arsenic is a well-established carcinogen in humans, but there little evidence for its carcinogenicity animals and it inactive as an initiator or tumor promoter two-stage models of mice. Two arsenic salts (sodium arsenite sodium arsenate) induced high frequency methotrexate-resistant 3T6 cells, which were shown to have amplified copies the dihydrofolate reductase gene. The ability induce gene amplification may relate carcinogenic effects humans since oncogenes observed many human tumors....

Arsenic is a notorious environmental toxicant known as both carcinogen and an atherogen in human beings, but the pathogenic mechanisms are not completely understood. In cell culture studies, trivalent arsenic enhanced oxidative stress variety of mammalian cells, this association may be closely associated with development arsenic-related diseases. To investigate effect exposure on humans, we conducted population study to determine relationships blood reactive oxidants antioxidant capacity at...

Sodium arsenite and sodium arsenate were observed to induce morphological transformation of Syrian hamster embryo cells in a dose-dependent manner. A linear dose-dependence with slope ∼1 was both compounds when the data plotted on log-log graph. The trivalent > 10-fold more potent than pentavalent arsenate. also exhibited toxicity; however, at non-toxic as well toxic doses. At low doses, enhanced colony-forming efficiency observed. To understand mechanism arsenic-induced transformation,...

Cancer-initiating cells (CICs) are responsible for tumor initiation, progression, and therapeutic resistance; moreover, redox homeostasis is important in regulating cancer stemness. Previously, we have identified that containing low intracellular reactive oxygen species levels (ROSLow cells) display enhanced features of CICs. However, the specific metabolic signatures CICs remain unclear required further characterization by systemic screenings. Herein, first showed mainly relying on...

Arsenic exposure is associated with an increased risk of vascular disorders, and results in oxidative stress endothelial cells smooth muscle (VSMCs). Since involved regulating the expression genes related to atherogenesis, we investigated its involvement enhanced three atherosclerosis-related coding for heme oxygenase-1 (HO-1), monocyte chemoattractant protein-1 (MCP-1), interleukin-6 (IL-6) VSMCs treated inorganic sodium arsenite (iAs). In human (hVSMCs) rat (rVSMCs), HO-1, MCP-1, IL-6 mRNA...

Silicosis is characterized by fibrosing nodular lesions that may eventually develop into progressive massive fibrosis (PMF). Cytokines (interleukin-1beta [IL-1beta], tumor necrosis factor-alpha [TNF-alpha] and growth factors insulin-like factor-1 [IGF-1] platelet-derived factor [PDGF]) have been implicated in the formation of these lesions. TGF-beta promotes extracellular matrix accumulation upregulating collagen fibronectin gene expression, inhibits degradation decreasing secretion...

CBLC (CBL proto-oncogene c) belongs to the CBL protein family, which has E3 ubiquitin ligase activity toward activated receptor tyrosine kinases. is frequently upregulated in non-small cell lung cancer (NSCLC), yet very little known about functions of tumorigenesis. Here we show that an epigenetically demethylated target and its expression can be NSCLC after treatment with DNA methylation inhibitor 5'-azacytidine. Depletion significantly inhibited viability clonogenicity vitro reduced tumor...
