ABSTRACT
Objective:
To study the effects of LPS and TNF-? on the expression of SSeCKS and morphology as well as cytoskeleton of endothelial cell, so as to explore the role of SSeCKS in cell morphology changes.Methods:
The cultured Bovine pulmonary artery endothelial cells(BPAEC) was induced by LPS, TNF-? and the expression of SSeCKS was detected by in situ hybridization,Western blot and immunohistology. Immunofluorescent staining method with confocal laser-scanning fluorescence microscope was used to observe the effects of LPS and TNF-? on the morphology of endothelial cells and the organisation of SSeCKS as well as cytoskeleton.Results:
Firstly, we found that TNF-? could induce the expression of SSeCKS in a concentration and time dependent manner , meanwhile LPS had no effects on SSeCKS expression. Secondly, it was observed that LPS and TNF-? induced reorganization of F-actin and SSeCKS in endothelial cell. Thirdly,PKC inhibitor Ro-31-8220 reversed the effect of LPS,TNF-? on F-actin and SSeCKS in endothelial cells.Conclusion:
The results demonstrate that TNF-? could induce endothelial cell to express SSeCKS; PKC plays a role in the reorganization of SSeCKS and F-actin in endothelial cells induced by LPS and TNF-?; the results suggest that the mechanism for reorganization of cytoskeleton induced by LPS, TNF-? be partially related to the SSeCKS of ECs.
