  • Inducible promoter for rice expression system, synthetic biological platform and use thereof
    Patent number: 12371705
    Abstract: Provided is a promoter sequence induced by methyl jasmonate. Also provided are an expression cassette, a recombinant vector and a recombinant cell comprising the promoter sequence. In addition, further provided is a method for producing an exogenous protein using the expression vector, and in particular a method for producing a human elastin in a rice cell using the expression vector. Further provided is a skin care composition comprising the exogenous protein. The composition is not cytotoxic to HaCaT cell lines and CCD966SK cell lines, and can increase the expression levels of water retention-related genes hHAS2, hHAS3, hAQP3 and hFLG in a cell, thereby improving the water retention and barrier functions in the cell as well as having a broad application prospect.
    Type: Grant
