Objective To investigate the effects of lipopolysaccharide(LPS) on Src-suppressed C Kinase Substrate(SSeCKS) in cultured astrocytes. Methods Purified astrocytes were randomly divided into three groups:control group,singly stressed and multiple stressed groups.The expression of SSeCKS was detected by Real time RT-PCR and Western blotting,while immunocytochemistry was used to investigate the subcellular localization of it. Results Real time RT-PCR indicated that,after 12 hours incubation,both 100 ?g/L and 1mg/L LPS were able to elevate the levels of SSeCKS mRNA compared with control group,while 1mg/L LPS did not have a stronger effect than 100 ?g/L.Western blotting analysis showed 100 ?g/L LPS significantly increased the expression of SSeCKS.In time response experiments,the levels of SSeCKS expression enhanced three hours after the stimulation,peaked at the sixth hour,coincident with its rapid phosphorylation,and remained high until the 24th hour.Immunocytochemistry suggested a perinuclear translocation of SSeCKS,while the PKC inhibitor RO-31-8220 blocked it.Conclusion In cultured astrocytes,LPS can enhance the expression of SSeCKS,increase its phosphorylation level and change its subcellular localization.These effects are correlated with the PKC pathway,which indicates SSeCKS might participate in the signal transduction of inflammation in cultured astrocytes.

AIM: To evaluate the expression of iNOS mRNA in different invasion ability colon carcinoma cell strains. METHODS: MTT was used to detect the growth and reproduction of colon cancer cell strain CW-2 and LS174T. RT-PCR and Northern blot were used to detect expression of iNOS mRNA in colon cancer. RESULTS: MTT growth curve displayed that colon cancer cell strain LS174T grew and reproduced faster than cell strain CW-2. RT-PCR showed that iNOS mRNA expressed strongly in CW-2 cell strain, while iNOS mRNA expressed weakly in LS174T cell strain. Northern blot detected that iNOS mRNA expressed obviously in CW-2 cell strain, but cell strain LS174T have no obvious iNOS mRNA expression. All-trans retinoic acid (ATRA) had no obvious effect on iNOS mRNA expression in CW-2 cell strain of colon cancer. CONCLUSIONS: ATRA has no obvious effect on iNOS mRNA expression. iNOS has a dual effect on tumor growth. In low-metastatic colon carcinoma CW-2, iNOS may exert a anti-tumor influence by cytotoxicity or inducing cell apoptosis. In high-metastatic colon cancer LS174T, iNOS produced low concentration of NO, which may be an important signal-transduction molecule for increasing blood supply and angiogenesis, which improve the growth, invasion and metastasis of tumor.
