Abstract
Background and purpose: Recently
studies showed that non-steroidal anti-inflammatory drugs (NSAIDs) could reduce the incidence of cancer. Whether ibuprofen could inhibit the growth of hepatocellular carcinoma cells had not been reported yet. In the current study
we investigated the effects of ibuprof
en on hepatoma carcinoma BEL-7402 cells and the relevant mechanisms. Methods: Hepatocellular carcinoma BEL-7402 cells were randomly divided into 7 groups: the control group and the ibuprofen groups (0.1
0.5
1.0
2.0
3.0 and 4.0 mmol/L). The effect of ibuprofen on BEL-7402 HCC cells was measured by MTT method
the cell cycles were analyzed by flow cytometry (FCM)
cell vitality and apoptosis were determined by cell analyzer. PCNA
Cyclin D1
Bcl-2 and COX-2 protein levels were examined by Western blot
and the expressions of prostaglandin E
2
(PGE

) were measured by ELISA. Results: After the exposure to ibuprofen
the suppression ratio of BEL-7402 cells was increased (P0.05). BEL-7402 cell vitality was decreased by degrees significantly (P0.05)
early apoptosis of BEL-7402 cells was increased (P0.05)
and the G

l
phase ratio was increased significantly compared with control group (P0.05). Ibuprofen effectively decreased PCNA
Cyclin D1
Bcl-2 and COX-2 expressions in BEL-7402 cells (P0.05)
and decreased PGE
2
protein expression in cell culture supernatants significantly (P0.05). Conclusion: Ibuprofen is effective for inhibiting the proliferations
increasing apoptosis and blocking cell cycles of BEL-7402 HCC cells. The anti-tumor mechanisms of ibuprofen may be related with the inhibition of COX-2 and PGE
