In this study, we applied small interfering RNA targeting the CXCR4 gene and the clinical treatment gemcitabine of ovarian cancer as the therapeutic drug, and organically integrate chemotherapy and gene therapy through carbon nanotubes, and use CD44v6 single chain antibody as the targeting moiety to explore its application in ovarian cancer treatment. This evidence concerns the gene CXCR4 and ovarian carcinoma.
