Impact of cryptotanshinone on C5a induced chemotactic migration The standard chemotactic stimulus of C5a was selected on the basis of our prior findings.
At noncytotoxic doses, an ethanolic Fostamatinib extract of Danshen exerted a consistent inhibitory effect on C5a stimulated cell migration. Cryptotanshinone alone did not influence the spontaneous transmigration, but significantly and 92%, respectively.
1711. 2%, 42. 379. 5% and 23. 6710. 1% by treatment with 0. 1 mM wortmannin, respectively. Furthermore, preincubation with a mouse embryonic kidney 1/2 inhibitor PD98059 or a p38 MAPK inhibitor SB203580 also caused a concentration dependent inhibition of C5a induced cell migration from 100% to 62. 574. 6% and 32. 977. 2%, and from 100% to 51. 375. 7% and 27. 277. 3%, respectively. Hedgehog inhibitor In contrast, the JNK inhibitor SP600125 failed to decrease the response of C5a at the concentrations used. The concentrations used for all protein kinase inhibitors were non cytotoxic to cells, cell viability after drug treatment were all greater than 95% as measured by Alamar Blue Assay. These results were consistent with our previous report and suggested that activation of PI3K, ERK1/2 and p38 MAPK signal pathways might be the main participants in the response to C5a.
Results showed that none of the concentrations used for cryptotanshinone displayed significant cytotoxicity: cell viability in the presence of 30 mM cryptotanshinone in RAW264. 7 cells and human primary macrophages were greater than 95% Figure 3 shows five Hedgehog inhibitor representative immunoblot and pooled data from at least four independent experiments examining the membrane translocation of PI3K p110g and the phosphorylation of protein kinases Fostamatinib by C5a stimulation, before and after cryptotanshinone treatment, respectively.
In the presence of cryptotanshinone, both PI3K p110g membrane translocation and Akt phosphorylation were significantly attenuated. On the other hand, three MAPK phosphorylations were also significantly triggered by C5a stimulation.
