[Methods] SGC-7901 cell lines were treated with ligustrazine and DDP alone or combined for 48 h for Western blot analysis, respectively. Western blot analysis was used to determine the expression of proteins involved in apoptosis including NF-κB p65, bax and caspase-3. [Results] The viability of SGC-7901 cells was inhibited after treated with ligustrazine and/or combined with DDP. The expression of NF-κB P65 protein decreased after treated with drugs, in which the protein decreased significantly in 1.2 mg/ml of TMP combined with 2 μg/ml of DDP group.Meanwhile, we investigated the protein expression of bax and caspase-3. The results showed that the expression of the two proteins increased following with the increasing concentration of TMP. [Conclusion] All the results indicated that ligustrazine combined with DDP could induce the apoptosis of SGC-7901 cell lines, and NF-κB maybe the possible way to induce the cell apoptosis.展开更多
