Claims3
A method for reducing cancer cell proliferation in vitro, the method comprising the steps of:
- a) transforming a Saccharomyces cervisiae cell with an expression cassette comprising the nucleic acid sequence according to SEQ ID NO:1;
- b) culturing the eukaryotic cell in a culture medium, wherein the cell secretes a recombinant mature human fetoprotein consisting of the amino acid sequence according to SEQ ID NO:2 into the culture medium;
- c) isolating the recombinant mature human alpha-fetoprotein (rhAFP) from the culture medium;
- d) providing a non-covalent complex of the recombinant mature human alpha-fetoprotein (rhAFP) isolated from the culture medium and curcumin or genistein, and
- e) contacting a cancer cell culture with the non-covalent complex.
