Abstract:
This study was purposed to investigate the mechanism of C-reactive protein (CRP) on proliferation of U266 cells. The human multiple myeloma cell line U266 was incubated with human CRP (0, 5, 10, 20 mg/L) for 24 hours, then the proliferation level of U266 cells was detected by using blood analyser. The mRNA expressions of survivin and HSP90alpha were examined by RT-PCR. The results showed that the proliferation ratio was increased, as compared with the control group (p<0.05); furthermore, the mRNA levels of survivin and HSP90alpha were up-regulated in proportion to the increased CRP concentrations. There was significant correlation between expression of survivin and HSP90alpha (r=0.737, p<0.0001) in incubated cells. It is concluded that CRP can stimulate the proliferation of MM cells directly by up-regulating the expression of survivin and HSP90alpha in MM cells. CRP can be regarded as a potential target for MM treatment.
