ICI118551联合吉西他滨对胰腺癌细胞BxPC-3增殖和凋亡的影响及其机制
Effect and mechanisms of ICI 118551 combined with gemcitabine on the proliferation and apoptosis of BxP C-3 cells
摘要
Abstract
To investigate the anti-proliferative effects of P,-adrenoceptor blocker ICI 118551, gemcitabine and ICI 118551 + gemcitabine on BxPC-3 cells and further analyze the underlying mechanisms. Methods MTT was used to detect the anti-prolifcrativc effect of ICI 118551, gemcitabine and ICI 118551 + gemcitabine on BxPC-3 cells. The apoptosis index was determined using TUNEL, and Annexin V and fluorescein isothiocyanate/propidium iodide flow cytometry assay, respectively. Expressions of Bcl-2 and Bax mRNA were detected by RT-PCR. Protein levels of Bcl-2, Bax and NF-kB subunit P65 were analyzed by Western blotting. Results ICI 118551, gemcitabine and ICI 118551 + gemcitabine could suppress proliferation of BxPC-3 cells. ICI 118551 + gemcitabine showed a higher apoptosis rate induction than ICI 118551 or gemcitabine alone. When cells were treated with gemcitabine in combination with ICI 118551, NF-kB activation was blocked; the expression of Bax/Bcl-2 protein was substantially increased. Conclusion ICI 118551 combined with gemcitabine has a synergistic anticancer effect on BxPC-3 cells, and the combination may be an effective therapeutic strategy for pancreatic cancer.关键词
