The circulating miRNAs are sufficiently stable and detectable to serve as clinical biomarkers as recent studies have revealed that the aberrant expression of circulating miRNAs can directly reflect disease status. Based on the analysis of the data (using miRanda software, TargetScan software and SOLID high-throughput sequencing) obtained from the(More)
Cells release exosomes to transfer various molecules to other cells. Exosomes are involved in a number of physiological and pathological processes. They are emerging great potential utility for diseases diagnosis and treatment recently. However, the internalization and intracellular trafficking of exosomes have not been described clearly. In this work,(More)
Stem cells used for clinical tissue regeneration therapy should have the capacity of self-renewal, high proliferation, and differentiation and be able to be transplanted in large numbers. Although high concentrations of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) may induce the differentiation of stem cells, these factors have(More)
MicroRNAs (miRNAs), a class of small RNAs, are important molecules that influence several developmental processes and regulate RNA interference (RNAi), and are abundant in animals, plants, and plant tissues that are traditionally consumed in the diet. The survival of plant small RNAs from the diet in animals, however, remains unclear, and the persistence of(More)
The cytotoxicity of nanomaterials has become a major concern in the field of nanotechnology. The key challenge is the lack of reliable methods to examine the overall cellular effects of nanomaterials. Here, a new method is developed to assess the cytological effects of nanomaterial basing on miRNA expression profiling. The SOLiD sequencing is used to(More)
Colorectal cancer (CRC) is one of the most commonly diagnosed cancers and a major cause of cancer death. However, the molecular mechanisms underlying CRC initiation, growth and metastasis are poorly understood. In this study, based on our previous work for comprehensively analyzing miRNA sequencing data, we examined a series of colorectal cancer microRNAs(More)
Nanoparticles were recently reported to be able to improve both efficiency and specificity in polymerase chain reaction (PCR). Here, CdTe QDs were introduced into multi-PCR systems. It was found that an appropriate concentration of CdTe QDs could enhance the performance of multi-PCR by reducing the formation of nonspecific products in the complex system,(More)
Epigenetic aspects of the cytotoxicity of CdTe quantum dots (QDs) recently have attracted more attention for their ability to reprogram gene expression after initial signals have been removed. And the involvement of epigenetic mechanisms in microRNA (miRNA) biogenesis suggests that miRNAs act as participants in the cytotoxicity of CdTe QDs. According to the(More)
The biggest challenge in the field of gene therapy is how to effectively deliver target genes to special cells. This study aimed to develop a new type of poly(D,L-lactide-co-glycolide) (PLGA)-based nanoparticles for gene delivery, which are capable of overcoming the disadvantages of polyethylenimine (PEI)- or cationic liposome-based gene carrier, such as(More)
Deregulated microRNAs (miRNAs) have been reported to be of functional relevance for tumor biology. In this study, we analyzed the small RNA transcriptomes of 10 paired colorectal cancer samples using SOLiD next-generation sequencing, and generated a total of >15141000 reads. miRNA expression profiles obtained by SOLiD sequencing correlated well with(More)
