2.In silico identification of cancer genes by high throughput analyses
Journal of Xi'an Jiaotong University(Medical Sciences) 2009;30(6):694-700
Objective To identify potential candidate genes related to the cancerous phenotype by analyzing databases publicly available. Methods Using a data-mining tool called Digital Differential Display (DDD) from the Cancer Gene Anatomy Project database, ESTs from 17 different tumor types were analyzed for differential expression. Results We obtained 130 up-regulated and 159 down-regulated genes, most of which are related to cytoskeleton, ribosomal subunit, substance metabolism, cell cycle, signal conduction, transcription and translation. These genes appear most frequently on chromosome 12 but rarely on chromosome 21 and Y. Conclusion In silico identification is a high-throughput screening strategy. Our study may lay a foundation for identification of future caner markers and provide a new thought for screening strategy of cancer markers.
3.Progress in differentiation of hepatocytes from embryonic stem cells
International Journal of Biomedical Engineering 2008;31(4):205-208
Acute liver failure and end-stage liver diseases are llfe-threatening.So far,orthotopic liver transplantation is the unique treatment available for these late-stage liver diseases,which,however,is limited by the lack of donor liver.While hepatocyte transplantation,bioartificial liver and tissue engineered liver are potential alternative treatments,the limited availability of functional hepatoeytes is the major hurdle.Due to their extensive capacity for self-renewal and pluripotency to differentiate into cells,embryonic stem cells represent a potential unlimited cell source for therapy.The clinical application of embryonic stem cells in liver diseases requires well-defined and efficient protocols for differentiation,characterization and purification in vitro.Hepatic differentiation of embryonic stem cells in different culttire systelns and the problems remained are reviewed in this article.
5.Modulation of nuclear receptors on drug-metabolizing enzymes and transporters.
Acta Pharmaceutica Sinica 2012;47(12):1575-81
PXR, CAR and PPAR, widely distributed in the body, are important members of the nuclear receptors (NRs) family. The activities and gene expressions of drug-metabolizing enzymes (DMEs) and transporters can be regulated by the activation of NRs, which effect the drug disposition. Multidrug resistance (MDR) is the leading cause of failure in cancer therapy. NRs, including PXR, CAR and PPAR, were shown to regulate the expressions of DMEs and transporters involved in the drug metabolism and clearance, suggesting that the modulation of NRs can be considered as a new target to overcome MDR. This review described the research progress of NR family members PXR, CAR, PPAR and their transcriptional activation mechanism, the regulation of DMEs and transporters by NRs, which may provide a valuable reference for clinical medication and overcome of MDR.
