MOTIVATION Systematic differences due to experimental features of microarray experiments are present in most large microarray data sets. Many different experimental features can cause biases including different sources of RNA, different production lots of microarrays or different microarray platforms. These systematic effects present a substantial hurdle to(More)
Silencing specificity is a critical issue in the therapeutic applications of siRNA, particularly in the treatment of single nucleotide polymorphism (SNP) diseases where discrimination against single nucleotide variation is demanded. However, no generally applicable guidelines are available for the design of such allele-specific siRNAs. In this paper, the(More)
To understand whether any human-specific new genes may be associated with human brain functions, we computationally screened the genetic vulnerable factors identified through Genome-Wide Association Studies and linkage analyses of nicotine addiction and found one human-specific de novo protein-coding gene, FLJ33706 (alternative gene symbol C20orf203).(More)
The specificity of small interfering RNA (siRNA)-mediated gene silencing is a critical consideration for the application of RNA interference (RNAi). While the discovery of potential off-target effects by siRNAs is of concern, no systematic analysis has been conducted to explore the specificity of RNAi. Here, we present a study where a functionally validated(More)
Liver-specific microRNA-122 (miR-122) is involved in the replication of hepatitis C virus (HCV) and its potential as a target for antiviral intervention was recently assessed. However, the use of circulating miR-122 in the evaluation of liver function has never been reported. In the present study, changes of serum miRNA levels were first evaluated in acute(More)
As a conserved non-coding RNA gene, transcripts of MALAT-1 localize predominately in the nucleus. However in G2/M cell cycle phase, MALAT-1 transcripts were surprisingly found to translocate from the nucleus into the cytoplasm. Investigation also found that in this process MALAT-1 interacts with an abundant nuclear factor, hnRNP C protein. Using a(More)
Cloutier and Widom [Cloutier, T. E. & Widom, J. (2004) Mol. Cell 14, 355-362] recently reported that the cyclization efficiency of short DNA fragments, about 100 bp in length, exceeds theoretical expectations by three orders of magnitude. In an effort to resolve this discrepancy, we tried modifying the theory. We investigated how the distribution of the(More)
BACKGROUND Galectin-3 plays a significant role in microglia activation. Its increased circulating concentration has been associated with some inflammatory diseases. In-hospital major adverse events (IMAEs), including acute traumatic coagulopathy, progressive hemorrhagic injury and posttraumatic cerebral infarction, have high prevalence and are strong(More)
Previous studies have suggested that microRNAs (miRNAs) may play important roles in tumorigenesis, but little is known about the functions of most miRNAs in cancer development. In the present study, we set up a cell-based screen using a luciferase reporter plasmid carrying the whole approximately 4.7 kb 3'-UTR of estrogen receptor alpha (ERalpha) mRNA(More)
During recent decades there have been remarkable advances in biology, in which one of the most important discoveries is RNA interference (RNAi). RNAi is a specific post-transcriptional regulatory pathway that can result in silencing gene functions. Efforts have been done to translate this new discovery into clinical applications for disease treatment.(More)
