    摘要: The present invention relates to a rapid and simple method for mass production of taxol from the cell culture of Taxus genus plant with a high purity and recovery. The method for mass production of taxol from Taxus genus plant of the present invention, comprises the steps of: (i) organic solvent extraction of biomass from Taxus genus plant to obtain a crude extract; (ii) synthetic adsorbent treatment of the crude extract and filtration to give filtrate; (iii) addition of hexane to the filtrate to precipitate crude taxol; (iv) fractional precipitation of the crude taxol in a mixture of alcohol and water and vacuum drying the precipitate to obtain taxol powder; and, (v) high performance liquid chromatography of the taxol powder. According to the method of the present invention, taxol of over 99% purity can be simply obtained from Taxus genus plant with a high recovery of over 90%.

    摘要: The present invention relate to a method to increase the production level of paclitaxel by changing the temperature during the plant cell culture. According to the present invention, the production of the paclitaxel comprises the following procedure: (i) cultivating the Taxus genus plant cells in a medium at ca. 20 to 25° C.; and (ii) when growth of the plant cells has progressed sufficiently, changing the cultivation temperature to ca. 26 to 32° C. to continue the culture. The present invention comprises also the method of increasing the paclitaxel production by inoculating the cells at a high initial concentration and by increasing the saccharide concentration in the medium: According to the present invention, paclitaxel can be mass-produced conveniently and therefore has an industrial application.

    摘要: The present invention relates to a diagnosis method of cancer using SYG972 gene and to the genomic DNA and to a promoter regulating transcription of the gene. Expression of SYG972 gene is greatly reduced in breast cancer cells compared to normal breast cells. Therefore the present invention provides a method of diagnosis method by using the gene of the present invention or its fragments as a probe. SYG972 genomic according to the present invention is composed of 4 exons and 3 introns. Promoter is 3 kb long from the transcription initiating site in the 5′ direction. SYG972 genomic DNA and promoter can be used to design and screen drugs to promote or to inhibit apoptosis and differentiation of cells, especially to screen drugs to treat cancer, a disease wherein cell growth and differentiation is abnormal.

    摘要: The present invention relates to a novel use of histone and provides a pharmaceutical composition containing histone as an active ingredient to improve the symptoms of progressive, inflammatory and autoimmune arthritis. The pharmaceutical composition of the present invention includes histone, especially histone H1 as an active ingredient, and could include pharmacologically approved carriers if necessary. Histone H1 lowered induction of arthritis and reduced arthritis index more effectively than steroidal dexamethasone and also had a significant preventive effect.
