    Abstract:
    CD147, also named extracelluar matrix metalloproteinase inducer (EMMPRIN), is a member of the immunoglobulin family and a glycoprotein enriched on the surface of tumor cells, which promotes invasion, metastasis, growth and survival of malignant cells, and is known to confer resistance to some chemotherapeutic drugs. To determine the possible role of CD147 in the invasive properties of laryngeal carcinoma, we used an RNA interference approach to silence CD147 expression in the Hep2 cell line at high levels of CD147 expression. Our results showed that CD147 expression was significantly impeded at both mRNA and protein levels, which resulted in a decrease of the Hep2 invasion activity in vitro and tumorigenicity in nude mice. The suppression of CD147 expression also sensitized cells to cisplatin. Our current results indicated that CD147 was a laryngeal carcinoma-related gene and CD147 might be a potential target for therapeutic anti-cancer drugs.
