RNA binding proteins (RBPs) and microRNAs (miRNAs) are two of the most important post-transcriptional regulators of gene expression, and their aberrant expression contributes to the development of human malignancies. Let-7, one of the most well-known tumor suppressors, is frequently down-regulated in a variety of human cancers. The RBP LIN28A/LIN28B, a(More)
This study explored the importance of hepatitis B virus infection in cholangiocarcinoma pathogenesis in northern China. The clinical data of 66 patients with cholangiocarcinoma were analyzed. The hepatitis B virus gene was amplified using nested polymerase chain reaction, and the hepatitis B virus-related antigen was detected using immunohistochemistry in(More)
IgA nephropathy (IgAN) is prevalent among both children and adults. Illumination of the differences between them is important for clinical doctors. We retrospectively compared clinicopathological features in 110 children and 908 adults with IgAN. The male to female ratio was 1.62:1 in children and 0.85:1 in adults. Most patients lacked triggers, but IgAN(More)
OBJECTIVE Signal transducer and activator of transcription 3 (STAT3) are constitutively activated in a variety of cancers and it is a common feature of ovarian cancer. Thus, STAT3 represents a promising molecular target for tumor therapy. We applied a DNA vector-based STAT3-specific RNA interference approach which specifically blocks over-activated STAT3,(More)
Non-coding RNAs represent a majority of the human transcriptome. However, less is known about the functions and regulatory mechanisms of most non-coding species. Moreover, little is known about the potential non-coding functions of coding RNAs. The competing endogenous RNAs (ceRNAs) hypothesis is proposed recently. This hypothesis describes potential(More)
To investigate the effect of HBV on the proliferative ability of host cells and explore the potential mechanism. MTT, colony formation assay and tumourigenicity in nude mice were performed to investigate the effect of HBV on the proliferative capability of host cells. In order to explore the potential mechanism, cell cycle and apoptosis were analysed. The(More)
Long noncoding RNAs (lncRNAs) are longer than 200-nucleotide, noncoding transcripts in length, have a variety of biological functions, and are closely associated with tumor development. Ovarian cancer, as 1 of the 3 common gynecological malignancies, is the leading cause of death in women with gynecological malignant tumor. In this study, a review of the(More)
E-cadherin is a well-known mediator of cell-cell adherens junctions. However, many other functions of E-cadherin have been reported. Collectively, the available data suggest that E-cadherin may also act as a gene transcriptional regulator. Here, evidence supporting this claim is reviewed, and possible mechanisms of action are discussed. E-cadherin has been(More)
Color quantization is wildly exploited for many applications especially in the fields of computer graphics and image processing. After studying the approaches of color clustering, a new approach based on ant colony clustering algorithm applied in color image quantization is proposed in the paper. According to the picking up-dropping theory, a promoted ant(More)
More than 90% of the human genome is actively transcribed, but less than 2% of the total genome encodes protein-coding RNA, and thus, noncoding RNA (ncRNA) is a major component of the human transcriptome. Recently, ncRNA was demonstrated to play important roles in multiple biological processes by directly or indirectly interfering with gene expression, and(More)
