	1	真菌Cercospora beticola的12种毒素贝第高林对癌基因ras转导的肾上腺细胞生长的作用(英文)显示文摘AIM: To explore different effects of 12 beticolins, Cer-cospora beticola toxins, on ras-transformed adrenocorti-cal cell growth inhibition and their functional mechanism. METHODS: Beticolin-induced inhibition was measured with survival cell number determined by an automated photocolorimetric method. The penetration of beticolin was examined by confocal microscopy. Ras protein determined by Lowry method were separated by 14 % SDS-PAGE and electroblotted to Immobilon-P transfer membrane and detected with pan-Ras (Ab-3) monoclonal antibody. The Ca2+ chelation by beticolin was investigated using a calcium ionophore. RESULTS: Cell growth inhibition was found dose- and time-dependently at submicromolar level for beticolin-1, -2, and -13 (IC50 ≤250 nmol/L) and for beticolin-0, 6, and -11 (400 nmol/L ≤ IC50<500 nmol/L). The inhibition by beticolin-1 was immediate, independent of cell culture step and not reversible for 3-day treatment. Beticolin-3 and -4 were slightly active (1 μmol/L < IC50 ≤ 2 μmol/L)	丁国庆 Gabriella MAUME Hanan OSMAN Martine PADIEU Marie-Louise MILAT Claude HUMBERT Jean-Pierre BLEIN Bernard F MAUME	2001	Acta Pharmacologica Sinica2001，22，9：	0
