ABSTRACT
Objective:To investigate the effect of PLTP gene on CSE-induced IL-8 production in human alveolar Type Ⅱcells ( Adenocarcinomic human alveolar epithelial cells , A549 ) .Methods: The different concentrations of CSE co-cultured with human alveolar epithelial cell line ( A549 ) for 24 hours.MTT assay was performed to study the effect of CSE on human alveolar epithelial cell line(A549) growth.Expression levels of PLTP mRNA and IL-8 mRNA were examined by RT-PCR,protein of PLTP were examined by Western blot ,and protein of IL-8 was examined by ELISA .Results: MTT assay showed that the proliferation of A 549 cell line were stimulated by the 0.125%CSE,while the proliferation of A549 cell tends to decrease at high concentrations of CSE (2.0% CSE and 4.0%CSE),and in this middle concentrations of CSE (0.25%CSE ,0.5%CSE and 1.0%CSE),the proliferation of A549 cell was not significantly affected .Our studys suggested that PLTP and IL-8 release were induced by CSE in a concentration-dependent and time-dependent manner ,and expression levels of IL-8 obviously increased after silence PLTP gene .Conclusion:PLTP siRNA can increased CSE-induced IL-8 production in human alveolar epithelial cells (A549).
