摘要:
An expression vector containing appropriate mitochondrion-targeting sequences (MTS) and appropriate 3′UTR sequences provides efficient and stable delivery of a mRNA encoding a protein (CDS) to the mitochondrion of a mammalian cell. The MTS and 3′UTR sequences guide the CDS mRNA from the nuclear compartment of the cell to mitochondrion-bound polysomes, where the CDS is translated. This provides an efficient translocation of a mature functional protein into the mitochondria. A method of targeting mRNA expressed in the nuclear compartment of a mammalian cell to the mitochondrion is also provided. The vector and methods can be used to treat defects in mitochondrial function.

The present invention provides a method for diagnosing or determining the risk of developing Alzheimer's disease and for treating Alzheimer's disease with S-equol. An aspect of the present invention includes the use of a direct mitochondrial target engagement biomarker to diagnose or assess the risk of developing Alzheimer's disease. Another aspect of the present invention includes the use of a pharmaceutically effective amount of S-equol to treat or prevent Alzheimer's disease in a subject diagnosed with or determined to be at risk of developing Alzheimer's disease.
摘要:
Provided are: a protein complex capable of selectively and asymmetrically oxidizing an enantiomer of a secondary alcohol without adding a coenzyme and having an asymmetric oxidation activity in a water-soluble solvent system in the presence of oxygen; a method for producing the same; and a method for coating the protein complex with a high molecular weight compound. The method for producing the protein complex includes: (1) enclosing a crude water-soluble protein in a gel, air-oxidizing the gel, and eluting the protein complex into an aqueous solution; and (2) applying gravity to concentrate and precipitate the protein complex, redissolving the precipitate in an aqueous glycine sodium hydroxide solution of about 0.5 mM and allowing the same to homogeneously coexist with a high molecular weight compound, and re-precipitating the solution and dehydrating and drying the same to yield a protein complex coated with a high molecular weight compound.
摘要:
The inventors demonstrate that mRNA sorting to the mitochondrial surface is an efficient way to proceed to such an allotopic expression, and that this mRNA sorting can be controlled by selecting appropriate mitochondrion-targeting sequence (MTS) and appropriate 3′UTR sequences. The CDS sequence which codes for the protein to be delivered into the mitochondrion is guided by these appropriate MTS and 3′UTR sequences from the nuclear compartment to the mitochondrion-bound polysomes (where the CDS is translated), and aids in an efficient translocation of a mature functional protein into the mitochondria. Appropriate MTS and 3′UTR sequences correspond to those of nuclearly-transcribed mitochondrially-targeted mRNAs. The inventors demonstrate that, to obtain a stable therapeutically-effective importation, both an appropriate MTS and an appropriate 3′UTR should preferably be used.
