Résumé
Objective To study the cell proliferative effects of fungal immunomodulatory proteins from Ganoderma spp . on 26 gastric cancer cell lines in vitro .Method 26 human gastric cancer cell lines were treated with FIPs by MTS assay .The average optical density (OD) in 490 nm and inhibition rate (GI50 )was counted by Universal Microplate Spectrophotometer . Results Three FIPs showed similar profiling in 26 human gastric cancer cell lines after 72 h treatment in cell proliferation as-say ,which except for NUGC-4 and OCUM-1 did not showed obvious anti-proliferative effect ,the other 24 human gastric cell lines showed some anti-proliferative effects ,especially for 7 cell lines(NUGC-3 ,GTL-16 ,HGC-27 ,IM95m ,SNU-638 ,SNU-216 and SNU-5) showing strong potency ,with their GI50 less than 50 μg/ml .Conclusion FIPs showed strong anti-prolifera-tive effects in some human gastric cancer cell lines in vitro ,which had potential to be further developed as anti-gastric cancer drugs .
