Expression of CD163 in patients of non-small cell lung and effects of cancer cell migration and proliferation / 中国免疫学杂志

ABSTRACT

Objective:To investigate the expression of CD 163 in the plasma and tumor tissue of non-small cell lung cancer (NSCLC)patients,and the effects of cancer cell migration and proliferation .Methods:35 cases of NSCLC patients in our hospital as the study group,and 35 healthy volunteers as control group ,we used Real-time RCR to detect the expression of CD163 in the plasma and tumor tissue of NSCLC patients.Using small interfering RNA (siRNA) to inhibit the expression of CD163 in MH-2,and co-culture with A549.The level of cancer cell migration was observed by transwell and the level of cell proliferation was observed by CCK -8.Results:The expression of CD163 in the plasma and tumor tissue of NSCLC patients was significantly higher than the control group , the difference was statistically significant (P<0.05);after the expression of CD163 was suppressed in MH-2,the levels of cancer cell migration and proliferation were significantly decreased , the difference was statistically significant ( P<0.05 ) .Conclusion: The expression of CD163 in the plasma and tumor tissue of NSCLC patients is increased ,and may elevate the levels of cancer cell migration and proliferation.
