[A new method for screening mutant yeast strains with green fluorescent protein].

OBJECTIVE: To establish a fast and simple method for screening mutant yeast strains. MATERIALS AND METHODS: Homologous recombination technique was used to detect mutant yeast strains in yeast genomic library, with the green fluorescent protein gene as the reporter gene in the transposon. RESULTS: The strains that emitted green fluorescence were isolated, indicating that the gfp gene was inserted into the yeast genome by homologous recombination. CONCLUSION: This study established a useful method for functional genome study by homologous recombination technique, and provide an alternative for gene therapeutic drug development.

[The strategies of gene prolong expression in mammals].

Gene therapy holds great promises to a variety of inherited diseases. However, the limitations on extended and consistent foreign gene expression has severely hampered the development of applicable gene therapy approaches. Technologies are reviewed here including transponson integration, biolistic measures that pulse the naked plasmid into living organs, or the integration of eukaryotic cis elements into introns, 3' untranslated regions, or the integration of the EBV sequences, which could assist in the prolonged gene expression of the introduced foreign genes. These strategies may significantly promote the progresses of gene therapy.

DNA Microarray Chips Made on Surface of Ceramic Slides.

As a novel technology, DNA microarray chips are being used in gene detections. To make DNA chips capable of multiple probing, ceramic slides, instead of silicon wafer or glass slides, were used as the substrate upon which DNA microarray are deposited. Our study indicates that the ceramic DNA microarray chips can be applied to multiple hybridization and detection procedures, showing high specificity. The advantages in using ceramic substrates are discussed.
