Abstract: A method for alleviating at least one of the disturbance of bile acid metabolism, the disturbance of amino acid metabolism, and the disturbance of gut microbiota metabolism in a subject, comprising administering to the subject a composition or a health food comprising an active component selected from the group consisting of gallic acid, a pharmaceutically acceptable salt of gallic acid, a pharmaceutically acceptable ester of gallic acid, and combinations thereof.

Abstract: Disclosed herein are isolated peptides having nuclear localization activity and derived from the VP2 protein of chicken anemia virus (CAV). The isolated peptides are proven to be useful and effective in the nuclear delivery of a selected target substance, such as proteins, peptides, nucleic acids, pharmaceutically active agents, chemical substances, etc. The isolated peptide can transport a target substance, in particular a protein, into the nucleus of a mammalian cell by forming a conjugate with the target substance, or via an expression cassette capable of expressing a fusion protein having the isolated peptide and the target protein.

Abstract: Disclosed herein is an expression cassette adapted to be expressed in an E. coli host cell and having a first nucleic acid fragment encoding a full-length chicken anemia virus (CAV) VP1 protein. In particular, the first nucleic acid fragment has a 5?-region that encodes a N-terminal amino acid sequence of the full-length CAV VP1 protein and is codon-optimized as compared to a corresponding 5?-region of a wild-type CAV vp1 gene, thus to encode the full-length VP1 protein. Specifically, the optimized codons are introduced into the corresponding 5?-region of the wild-type CAV vp1 gene by codon replacements.
