MicroRNAs (miRNAs) are regulatory small non-coding RNAs that can regulate gene expression by binding to gene elements, such as the gene promotor 5'UTR, mainly in the 3'UTR of mRNA. One miRNA targets many mRNAs, which can be regulated by many miRNAs, leading to a complex metabolic network. In our study, we found that the expression level of miR-590-5p is(More)
Metastasis is responsible for the rapid recurrence and poor survival of malignancies. Epithelial-mesenchymal transition (EMT) has a critical role in metastasis. Increasing evidence indicates that EMT can be regulated by microRNAs (miRNAs). The aim of this study was to investigate the role of miR-26b in modulating epithelial-mesenchymal transition (EMT) in(More)
We have screened 11 isoquinoline derivatives and α-methylene-γ-butyrolactones using the 3-(4,5-dimethylthi-azol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity assay in HeLa and HEK-293T cells. Compound 2 was identified as potential anticancer agent. To further improve its therapeutic potential, this agent was incorporated into transferrin(More)
A growing amount of evidence supports that microRNA (miRNA) dysregulation is involved in cancer progression by directly downregulating multiple targets. Elucidating the underlying mechanism of miRNA in carcinogenesis may improve diagnostic and therapeutic strategies for malignancy. In the current study, we found that miR-105 expression was markedly(More)
BACKGROUND Our previous studies showed that glioma-associated oncogene (Gli)2 plays an important role in the proliferation and apoptosis resistance of hepatocellular carcinoma (HCC) cells. The aim of this study was to explore the clinical significance of Gli2 expression in HCC. METHODS Expression of Gli2 protein was detected in samples from 68 paired HCC(More)
Hepatocellular carcinoma (HCC) is one of the common malignancies, which is highly metastatic and the third common cause of cancer deaths in the world. The invasion and metastasis of cancer cells is a multistep and complex process which is mainly initiated by extracellular matrix (ECM) degradation. Aberrant expression of microRNA has been investigated in HCC(More)
The pre-mRNA splicing regulator serine-arginine protein kinase 1 (SRPK1) promotes cancer development and various pathophysiological processes. However, the clinical relevance of SRPK1 in hepatocellular carcinoma (HCC) is not clear. This study investigates the expression and prognostic value of SRPK1 in HCC. We found that SRPK1 expression was significantly(More)
A reduction-sensitive cross-linked polyethylenimine derivative PEI-SS-OA was synthesized and evaluated for oligonucleotide delivery. PEI-SS-OA was shown to condense LOR-2501, an oligonucleotide targeting ribonucleotide reductase R1 subunit (RRM1), into positively charged complexes. The reductive degradation of the PEI-SS-OA induced by dithiothreitol was(More)
This study was to investigate the composition and characteristics of long-straight chain alkane and fatty alcohols from the microalga Chlorella Sorokiniana 21, isolated from the coastal water of Pearl River Delta, China. Under the optimized aeration growth condition, this strain yielded up to 1.44 g L(-1) biomass and 24.90% extracts of dry weight. The major(More)
BACKGROUND To investigate the applicability of inbred Wuzhishan (WZS) miniature pigs for porcine islet isolation and purification. METHODS  Islet isolation and purification was conducted on adult (1-yr-old), male inbred WZS miniature pigs and age- and sex-matched market pigs obtained from a local slaughterhouse (control group). Pancreata were excised, and(More)
