PG - 244-7 AB - OBJECTIVE: To investigate monocyte chemotactic protein-3 (MCP-3) mRNA and protein expression and distribution in laryngeal squamous cell carcinoma (LSCC) tissue, so as to study its function in the tumor development. METHOD: Immunohistochemical staining and RT-PCR, and western blot were performed to detect the LSCC tissue and the normal tissue adjacent tumor. RESULT: The expression of MCP-3 mRNA and protein were found in the LSCC tissue and the normal tissue adjacent tumor. The expression of MCP-3 mRNA and protein in LSCC tissue is much higher than that in normal tissue adjacent tumor (P<0.05). There is a significant difference between I-II stage III-IV stage (P<0.05). Immunohistochemical staining: positive staining of MCP-3 was yellow and mainly detected in the tumor cell cytoplasm and also in some normal glandular epitheliums. CONCLUSION: MCP-3 might be involved in the mechanism of the tumor development, its function of chemotaxis and activation of the tumor-associated macrophages would be highlighted, so that the inflammatory microenvironment might play an important role in the development of tumor.
