The long noncoding RNA HOTAIR has been reported as a poor prognostic biomarker in patients with breast cancer. The aim of the present study is to examine the expression pattern of HOTAIR in hepatocellular carcinoma (HCC) and its clinical significance as well as its biological role in tumor progression. We examined the expression of HOTAIR in 110 HCC samples(More)
DIM-5 is a SUV39-type histone H3 Lys9 methyltransferase that is essential for DNA methylation in N. crassa. We report the structure of a ternary complex including DIM-5, S-adenosyl-L-homocysteine, and a substrate H3 peptide. The histone tail inserts as a parallel strand between two DIM-5 strands, completing a hybrid sheet. Three post-SET cysteines(More)
Metastasis-associated lung adenocarcinoma transcript 1(MALAT1), a long non-coding RNA (lncRNA), is up-regulated in many solid tumors and associated with cancer metastasis and recurrence. However, its role in hepatocellular carcinoma (HCC) remains poorly understood. In the present study, we evaluated the expression of MALAT1 by quantitative real-time PCR in(More)
A Hindley-Milner type system such as ML's seems to prohibit type-indexed values, <i>i.e</i>., functions that map a family of types to a family of values. Such functions generally perform case analysis on the input types and return values of possibly different types. The goal of our work is to demonstrate how to program with type-indexed values within a(More)
Conflicting data have been published as to the possible association between polymorphism in codon 72 of the TP53 tumor suppressor gene and the risk of developing breast cancer. In order to address this question, we carried out a meta-analysis of 21 studies of and this polymorphism and breast cancer risk, which collectively included 12,601 cases and 11,462(More)
The crystal structure of native chicken fibrinogen (320 kDa) complexed with two synthetic peptides has been determined at a resolution of 2.7 A. The structure provides the first atomic-resolution view of the polypeptide chain arrangement in the central domain where the two halves of the molecule are joined, as well as of a putative thrombin-binding site.(More)
The basic helix-loop-helix (bHLH) proteins play important regulatory roles in eukaryotic developmental processes including neurogenesis, myogenesis, hematopoiesis, sex determination, and gut development. Zebrafish is a good model organism for developmental biology. In this study, we identified 139 bHLH genes encoded in the zebrafish genome. Phylogenetic(More)
OBJECTIVE Long non-coding RNAs (lncRNAs) are emerging as key molecules in cancers, yet their potential molecular mechanisms are not well understood. The objective of this study is to examine the expression and functions of lncRNAs in the development of colorectal cancer (CRC). METHODS LncRNA expression profiling of CRC, adenoma and normal colorectal(More)
Picrotoxin, an antagonist of structurally-rated GABA(A) receptors (GABA(A)Rs) and glycine receptors (GlyRs), is an equimolar mixture of picrotoxinin (PTXININ) and picrotin (PTN). These compounds share a common structure except that PTN contains a slightly larger dimethylmethanol in place of the PTXININ isopropenyl group. Although the homomeric alpha1 GlyR(More)
