Objective To explore the expression of protein kinase C (PKC) and cytokines in airway epithelial cells interfered by lipopolysaccharide (LPS). Methods A549 cell line was cultivated and incubated with different concentrations of LPS for 2
4
8
24
30 and 48 h
respectively. The culture medium
and whole cell proteins were extracted
and the levels of cytokines including interleukin (IL)-1
IL-6
IL-8 and IL-11 secreted by A549 cells were detected by enzyme-linked immunosorbent assay (ELISA). Meanwhile
the expression of PKC was detected by Western blotting.
Results There were significant differences in the levels of IL-1
IL-6
IL-8
IL-11 and expression of PKC in the A549 cells interfered by various concentrations of LPS at the same time point (all
P
values
<
0.001). The expression of PKC was correlated with the level of IL-1 (
P
<
0.05). Conclusion The secretion of IL-1
IL-6
IL-8 and IL-11 and expression of PKC are interfered by LPS. The secretion of IL-1 interfered by PKC may be correlated with PKC signal pathway.
