Since upregulation of MALAT1 is associated with an elevated level of MCP-1 in plasma of AA lung cancer patients, we broadened our study to analyze MALAT1 and MCP-1 in lung tumor tissues and adjacent non-cancerous lung tissues of 46 NSCLC patients, including 23 AAs and 23 WAs. The gene discussed is CCL2; the disease is lung carcinoma.
