Many long non-coding RNA (lncRNA) genes identified in mammals have multiple exons and functional domains, allowing them to bind to polycomb proteins, DNA methyltransferases, and specific DNA sequences to regulate genome methylation. Little is known about the origin and evolution of lncRNAs. ANRIL/CDKN2B-AS consists of 19 exons on human chromosome 9p21 and(More)
We developed a simple, non-enzymatic approach for the colorimetric detection of glucose based on a gold nanoparticles (Au NPs) assisted silver mirror reaction (AuSMR). The linear range of the concentration of glucose is from 0.04 mM to 1 mM, and the lowest concentration that can be distinguished by the naked eye is 10 nM. This approach has been successfully(More)
BACKGROUND An increasing number of long noncoding RNAs (lncRNAs) have been identified recently. Different from all the others that function in cis to regulate local gene expression, the newly identified HOTAIR is located between HoxC11 and HoxC12 in the human genome and regulates HoxD expression in multiple tissues. Like the well-characterised lncRNA Xist,(More)
This letter presents a click-chemistry-based assay for proteins (CAP) that allows quantitative determination of the concentration of proteins, using azide- and alkyne-functionalized gold nanoparticles (AuNPs). Compared with conventional methods, CAP has a broader linear range for detection of proteins with good selectivity. CAP enables the analysis of total(More)
Angiogenesis plays an important role in tumor growth and metastasis, therefore antiangiogenic therapy was widely investigated as a promising approach for cancer therapy. Recently, pigment epithelium-derived factor (PEDF) has been shown to be the most potent inhibitor of angiogenesis. Adeno-associated virus (AAV) vectors have been intensively studied due to(More)
BACKGROUND There is scant information on characteristics, treatment, functional outcome and case fatality of ischemic stroke with atrial fibrillation (AF) in China. METHODS For this study, first-ever ischemic stroke patients who were admitted within 1 month of stroke onset during the period of March 2002 through December 2008 were included. Data on(More)
To date, even though various kinds of nanomaterials have been evaluated over the years in order to develop effective cancer therapy, there is still significant challenges in the improvement of the capabilities of nano-carriers. Developing a new theranostic nanomedicine platform for imaging-guided, visualized cancer therapy is currently a promising way to(More)
MOTIVATION In mammalian cells, many genes are silenced by genome methylation. DNA methyltransferases and polycomb repressive complexes, which both lack sequence-specific DNA-binding motifs, are recruited by long non-coding RNA (lncRNA) to specific genomic sites to methylate DNA and chromatin. Increasing evidence indicates that many lncRNAs contain(More)
Paramagnetic gadolinium (Gd(3+))-based nanocrystals (NCs) with a large number of confined gadolinium ions can be expected to heavily enhance the longitudinal (T1) relaxation of water protons compared to clinical gadolinium complexes with only a single paramagnetic center. However, paramagnetic Gd(3+)-NCs reported to date show only a modest T1 relaxivity of(More)
Tet methylcytosine dioxygenase 2 (TET2) gene mutations have recently been recognized in acute myeloid leukemia (AML). We performed a meta-analysis to evaluate the controversial prognostic significance of TET2 mutations in AML. Eight studies, covering 2552 patients with AML, were included in this analysis. Pooled hazard ratios (HRs) indicated that TET2(More)
