The invention is a constructing method of a genetic modified chlamydomonas reinhardtii to express kallikrein of human tissue. Firstly kallikrein gene sequence suitable for expression of chlamydomonas reinhardtii kernel genome or expression of chloroplast genome or expression of mitochondrial is designed according to kallikrein gene sequence of human tissue and preferred codon table of chlamydomonas reinhardtii, the gene sequence is synthesized by artificial synthesis, kallikrein gene of human tissue containing non-coded sequence is artificially synthesized, then expression vector of chlamydomonas reinhardtii kernel genome or expression vector of chlamydomonas reinhardtii chloroplast genome or expression vetor of chlamydomonas reinhardtii mitochondrial with mention foreign gene is constructed, then transformed into chlamydomonas reinhardtii by genetic transformation, and genetic modified algal strains capable of expressing kallikrein of human tissue is obtained after screening. The invention lays foundation of treating and preventing some diseases such as hypertention, glomerulonephritis with human original kallikrein gene chlamydomonas reinhardtii and products there.

Gene expression profiling and hierarchial clustering analysis readily distinguish normal ovarian epithelial cells from primary ovarian serous papillary carcinomas. Laminin, tumor-associated calcium signal transducer 1 and 2 (TROP-1 / Ep-CAM; TROP-2), claudin 3, claudin 4, ladinin 1, S100A2, SERPIN2 (PAI-2), CD24, lipocalin 2, osteopontin, kallikrein 6 (protease M), kallikrein 10, matriptase and stratifin were found among the most highly overexpressed genes in ovarian serous papillary carcinomas, whereas transforming growth factor beta receptor III, platelet-derived growth factor receptor alpha, SEMACAP3, ras homolog gene family, member I (ARHI), thrombospondin 2 and disabled-2 / differentially expressed in ovarian carcinoma 2 (Dab2 / DOC2) were significantly down-regulated. Therapeutic strategy targeting TROP-1 / Ep-CAM by monoclonal chimeric / humanized antibodies may be beneficial in patients harboring chemotherapy-resistant ovarian serous papillary carcinomas.
