BACKGROUND Human leukocyte antigen DP (HLA-DP) locus has been reported to be associated with hepatitis B virus (HBV) infection in populations of Japan and Thailand. We aimed to examine whether the association can be replicated in Han Chinese populations. METHODOLOGY/PRINCIPAL FINDINGS Two HLA-DP variants rs2395309 and rs9277535 (the most strongly(More)
Vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1 (HIF-1) are important regulators of angiogenesis. HIF-1 is composed of HIF-1alpha and HIF-1beta subunits, and regulates VEGF expression at transcriptional level. In this study, we demonstrated that insulin induced H2O2 production and p70S6K1 activation in PC-3 prostate cancer cells.(More)
Apigenin is a natural dietary flavonoid. It has recently been shown to have anticancer effects on prostate and ovarian cancer cells. However, the molecular basis of the effect of apigenin on cancer cells remains to be elucidated. In this study, we found that apigenin inhibited A549 lung cancer cell proliferation and vascular endothelial growth factor (VEGF)(More)
The discovery of long non-coding RNA (lncRNA) has dramatically altered our understanding of cancer. Here, we describe a comprehensive analysis of lncRNA alterations at transcriptional, genomic, and epigenetic levels in 5,037 human tumor specimens across 13 cancer types from The Cancer Genome Atlas. Our results suggest that the expression and dysregulation(More)
OBJECTIVES In ultrasound molecular imaging, a sequence of high-pressure ultrasound pulses is frequently applied to destroy bound targeted microbubbles, to quantify accumulated microbubbles or to prepare for successive microbubble injections; however, the potential for biological effects from such a strategy has not been fully investigated. Here, we(More)
Pulmonary Langerhans cell histiocytosis (PLCH) has been postulated to be a smoking-related non-neoplastic condition, distinct from extrapulmonary LCH, which is generally regarded as a clonal, neoplastic process. Recent genomic studies demonstrated BRAF V600E mutation in 38% to 57% of extrapulmonary LCH cases by polymerase chain reaction. We evaluated the(More)
Epidemiological and preclinical evidence supports that omega-3 dietary fatty acids (fish oil) reduce the risks of macular degeneration and cancers, but the mechanisms by which these omega-3 lipids inhibit angiogenesis and tumorigenesis are poorly understood. Here we show that epoxydocosapentaenoic acids (EDPs), which are lipid mediators produced by(More)
Oncomirs are microRNAs (miRNA) that acts as oncogenes or tumor suppressor genes. Efficient identification of oncomirs remains a challenge. Here we report a novel, clinically guided genetic screening approach for the identification of oncomirs, identifying mir-30d through this strategy. mir-30d regulates tumor cell proliferation, apoptosis, senescence, and(More)
Apigenin is a non-toxic dietary flavonoid with anti-tumor properties. We recently showed that apigenin-inhibited hypoxia-inducible factor-1 (HIF-1) and vascular endothelial growth factor (VEGF) expression in human ovarian cancer cells under normoxic condition. However, the effect of apigenin in angiogenesis remains to be elucidated. Angiogenesis is the(More)
Luteolin, a common dietary flavonoid, has been found to have antitumor properties and therefore poses special interest for the development of preventive and/or therapeutic agent for cancers. E-cadherin, a marker of epithelial cells, mediates cell-cell adhesion. Decreased expression of E-cadherin results in a loss of cell-cell adhesion and an increased cell(More)
