ABSTRACT
Objective To investigate the inhibitory effect of cucurmosin (CUS) combined with the commonly used chemotherapeutic drugs for pancreatic cancer in clinical practice including Gemcitabine (GEM),Fluorouracil (5-FU),Paclitaxel (PTX) and Cisplatin (DDP) on cell proliferation of human pancreatic cancer cell line BxPC-3.Mehtods Sulforhodamine B (SRB) assay was used to detect the inhibition on the cell proliferation of BxPC-3 cells in vitro after the treatment of CUS combined with GEM,5-FU,PTX and DDP,respectively.Colony formation assay was also conducted and Jin' s formula was used to assess the synergistic effect of these combinations.Results The inhibition rate of CUS combined with GEM,5-FU,PTX and DDP were all higher than those of each drug alone (q ＞ 0.85),which became obvious in low concentrations.The colony formation inhibition rate of CUS combined with GEM,5-FU,PTX or DDP were all higher than each single drug treatment (q ＞ 1.15).Conclusion CUS could enhance the cell growth inhibition of GEM,5-FU,PTX and DDP in BxPC-3 cells in vitro with a good synergistic effect.
