    标题:Treatment of neurodegenerative disorders
    发明人:DURGA JANE; VERHOEF PETRA
    权利人:WAGENINGEN CT FOR FOOD SCIENCE
    摘要:The present invention is dedicated to the treatment of neurodegenerative disorders, in particular age related cognitive decline and age related hearing loss. These disorders can be alleviated by increasing 10-formyltetrahydrofolate or increasing thymidylate synthesis. The invention is of particular benefit to subjects that are MTHFR 677CT heterozygote and MTHFR 677CC homozygote. n The substance that increases 10-formyltetrahydrofolate or increases thymidylate synthesis is selected from 10-formyltetrahydrofolate, 5-formyltetrahydrofolate, 5,10-methenyltetrahydrofolate, 5,10-methylentetrahydrofolate, methionine, S-adenosylmethionine and poly-glutamate forms of 10-formyltetrahydrofolate, 5-formyltetrahydrofolate, 5,10-methenyltetrahydrofolate and 5,10-methylentetrahydrofolate and the substance may be in an acid or salt or ester form.

    标 题:Co-production method for multiprotein system, co-production system for multiprotein system and use thereof

    权利人:SHENZHEN INST ADV TECH
    摘要:Provided are a co-production method for a multiprotein system, a co-production system for a multiprotein system and use thereof. Specifically, a vector for expressing a bacteriolytic protein and a plurality of vectors for expressing proteins are co-transferred into a protein expression strain, so that the obtained co-expression strain expresses corresponding proteins and bacteriolytic protein. As growth of the co-expression strain, the generated bacteriolytic protein acts on the co-expression strain, so that the co-expression strain is subject to autonomous lysis, and the expressed proteins are released, thereby forming a multi-protein system which can be used for in vitro synthesis of proteins and/or compounds.

    标 题:Process for producing peptides by using in vitro transcription/translation system
    发明人:INOUE AKIO; SHIMIZU YOSHIHIRO; UEDA TAKUYA
    权利人:POST GENOME INST CO LTD
    摘要:The present invention relates to a reaction system whereby a peptide produced in an in vitro peptide synthesis system can be efficiently isolated at a high purity from the reaction system. Thus the present invention is a process for producing a peptide or a peptide derivative by using a reaction system of transcribing a DNA into an RNA and then translating the RNA produced or a reaction system of translating an RNA in vitro wherein at least one protein component of the reaction system is labeled with a first substance which adheres to a second substance, and said second substance is used as an adsorbent for capturing said labeled protein components after translating.
