名稱 | Butein |
描述 | Butein is a cAMP-specific PDE inhibitor, protein tyrosine kinase inhibitor, and SIRT1 activator. It sensitizes HeLa cells to Cisplatin by targeting FoxO3a via the AKT and ERK/p38 MAPK pathways. |
細(xì)胞實(shí)驗(yàn) | The cells (5× 103/mL) are incubated in triplicate in a 96-well plate in the presence or absence of indicated concentration of Butein in a final volume of 0.2 mL for different time intervals at 37 ℃. Thereafter, 20 μL MTT solution (5 mg/mL in PBS) is added to each well. After a 2-hour incubation at 37 ℃, 0.1 mL lysis buffer (20% SDS, 50% dimethylformamide) is added, incubation is continued overnight at 37 ℃, and then the optical density at 570 nm is measured by plate reader.

方法:用Butein (2’,3,4,4’-tetrahydroxy Chalcone)(20μM)或 Cisplatin (20 μM)處理HeLa 細(xì)胞,Western blot分析檢測(cè)AKT、ERK和p38磷酸化水平。
結(jié)果:Butein (2’,3,4,4’-tetrahydroxy Chalcone)顯著抑制Cisplatin誘導(dǎo)的ERK和p38磷酸化,但對(duì)JNK表達(dá)有明顯影響;單獨(dú)使用Cisplatin或Butein (2’,3,4,4’-tetrahydroxy Chalcone)或聯(lián)合使用可抑制AKT激活。[3] |
