產(chǎn)品描述
SAHA又稱為Vorinostat、L-001079038、MK-0683、Suberoylanilide Hydroxamic Acid。
SAHA是一種有效的HDAC抑制劑,作用于HDAC1和HDAC3。SAHA引起組蛋白H4高度乙?;种萍?xì)胞增殖,并引起細(xì)胞周期阻斷,改變細(xì)胞形態(tài),如細(xì)胞質(zhì)變大、扁平,因此抑制細(xì)胞生長(zhǎng)。SAHA處理細(xì)胞后還會(huì)降低抗凋亡蛋白Bcl-xL和survivin蛋白表達(dá)降低。在體內(nèi),SAHA顯著抑制裸鼠體內(nèi)CWR22移植瘤生長(zhǎng)。Genistein和Vorinostat 聯(lián)合作用用抑制細(xì)胞增殖具有協(xié)同效應(yīng)。

使用濃度
【具體使用濃度請(qǐng)參考相關(guān)文獻(xiàn),并根據(jù)自身實(shí)驗(yàn)條件(如實(shí)驗(yàn)?zāi)康模?xì)胞種類,培養(yǎng)特性等)進(jìn)行摸索和優(yōu)化?!?/span>
相關(guān)實(shí)驗(yàn)(數(shù)據(jù)來(lái)自于公開(kāi)發(fā)表的文獻(xiàn),僅供參考)
(一)細(xì)胞實(shí)驗(yàn)(體外研究)
為檢測(cè)SAHA對(duì)細(xì)胞的作用,用不同濃度SAHA(0.5, 1, 3, 5, 10 μM)孵育MES-SA細(xì)胞,與對(duì)照組相比,低至0.5 μM SAHA也可以抑制細(xì)胞生長(zhǎng),濃度增加時(shí),抑制作用也隨之增強(qiáng)。[7]
(二)動(dòng)物實(shí)驗(yàn)(體內(nèi)研究)
在體內(nèi)實(shí)驗(yàn)中,50 mg/kg/day SAHA作用于MES-SA移植瘤小鼠,小鼠體內(nèi)腫瘤體積顯著變小,對(duì)照組為2304.7 mm3,而SAHA處理組為1135.4 mm3。[7]
