Long noncoding RNAs (lncRNAs) have been attracting immense research interest, while only a handful of lncRNAs have been characterized thoroughly. Their involvement in the fundamental cellular processes including regulate gene expression at epigenetics, transcription, and post-transcription highlighted a central role in cell homeostasis. However, lncRNAs(More)
Small interfering RNAs (siRNAs) silence the expression of specific target genes by mediating RNA interference (RNAi) in mammalian cells. siRNAs have not only been widely used as a valuable tool for functional genomics research, but they also have demonstrated great potential in biomedical therapeutic applications for diseases caused by abnormal gene(More)
Long non-coding RNAs (lncRNAs) are series of transcripts with important biological functions. Various diseases have been associated with aberrant expression of lncRNAs and the related dysregulation of mRNAs. In this review, we highlight the mechanisms of dynamic lncRNA expression. The chromatin state contributes to the low and specific expression of(More)
INTRODUCTION MicroRNAs (miRNAs), a class of small, regulatory and non-coding RNA molecules, display aberrant expression patterns and functional abnormalities in all kinds of human diseases including cancers. As important emerging modulators in cellular pathways, miRNAs play a key role in tumorigenesis. Correcting these miRNA deficiencies by either(More)
α-Lipoic acid (ALA) is known as a powerful antioxidant, which has been reported to have protective effects against various cardiovascular diseases. The present study aimed to determine whether ALA pre- or post-treatment induced protective effects against hypoxia/reoxygenation-induced injury via inhibition of apoptosis and autophagy in human umbilical vein(More)
Metastasis is a multistep process starting with the dissemination of tumor cells from a primary site and ending with secondary tumor development in an anatomically distant location. The epithelial-mesenchymal transition (EMT), a process that endows epithelial tumor cells with mesenchymal properties including reduced adhesion and increased motility, is(More)
The paper deals with the study of chemical constituents of the unmatured fruits of Chinese traditional medicine Momordica charantia L. which is usually used as green-stuff. There are two parts of the extracts obtained by ethanol precipitation, and four compounds obtained from the further isolation. They are identified as Vincine, Mycose, Momordicoside A and(More)
RNA targeting the murine vascular endothelial growth factor receptor 2 (VEGFR2) gene was designed and validated for efficient and robust silencing in vitro and was delivered by polyethylenimines (PEI) in vivo to investigate the antitumor effect on non-small cell lung cancer (NSCLC) xenografts. The following dosage(More)
Skeletal muscle differentiation has been shown to be dependent on the expression of Rb and p300. We recently cloned a novel inhibitor of muscle differentiation called EID-1, which interacted with both of these factors. In a database search for related molecules, we have cloned and characterized a new EID-1 family member, EID-2. This 28-kDa protein encodes a(More)
RNAi technology is taking strong position among the key therapeutic modalities, with dozens of siRNA-based programs entering and successfully progressing through clinical stages of drug development. To further explore potentials of RNAi technology as therapeutics, we engineered and tested VEGFR2 siRNA molecules specifically targeted to tumors through(More)
