[Expression of tissue factor induced by IL-6 in HUVEC].
OBJECTIVE
To investigate the effects of IL-6 at the expression of tissue factor (TF) in human vein endothelial cells(HUVECs).


METHODS
HUVECs were incubated with IL-6 at the concentration of 0.5 ng/mL. Cell viability was measured by CCK-8 assay. The TF mRNA was detected by reverse transcript-polymerase chain reaction(RT-PCR) method.


RESULTS
When HUVECs were exposed to IL-6 (0.5 ng/mL) within a period of 72 h, their viability did not decrease in comparison with the control; there was no statistical difference between the two groups. After the HUVECs were exposed to IL-6 (0.5 ng/mL) for 6 h, the TF mRNA level increased, and it reached the peak at 12 h; then it began to decline. The expression of TF mRNA induced by IL-6 was evidently detected from 6 h to 48 h. After the HUVECs were treated by IL-6 over 72 h, the expression of TF mRNA was no longer detected in HUVECs.


CONCLUSIONS
IL-6 at the concentration of 0.5 ng/mL did not exert direct effect on cell viability. The increase of TF mRNA expression in HUVECs induced by IL-6 could play an important role in the modulation of blood coagulation disorder and in the mechanism related to coagulation system changes during
