在細(xì)胞實(shí)驗(yàn)中,
SP600125(JNK Inhibitor II,AbMole,M2076)的使用濃度范圍較廣。例如,在人神經(jīng)母細(xì)胞瘤SH-SY5Y細(xì)胞中,30 μM 的SP600125可顯著抑制JNK磷酸化并保護(hù)細(xì)胞免受異氟烷誘導(dǎo)的損傷[1];在MG-63和Saos-2骨肉瘤細(xì)胞中,5 μM的SP600125被用于細(xì)胞癌變機(jī)制研究[2];SP600125(NSC75890)在大鼠心肌細(xì)胞H9c2中,以劑量依賴方式抑制高尿酸(HUA)誘導(dǎo)的脂肪積累及脂ogenic基因表達(dá)[3];SP600125在MC3T3-E1成骨前體細(xì)胞中,可逆轉(zhuǎn)鎘誘導(dǎo)的Runx2下調(diào)并提升細(xì)胞存活率[4];10 μM SP600125在人膠質(zhì)母細(xì)胞瘤細(xì)胞(GBMCs)中,處理24小時(shí)后顯著抑制增殖并上調(diào)HIF-1α與BMP4表達(dá)[5];SP600125在MH7A類風(fēng)濕關(guān)節(jié)炎滑膜成纖維細(xì)胞中,還能有效抑制MMP-3表達(dá),提示JNK/MMP通路可能是關(guān)節(jié)炎研究的新靶點(diǎn)[6];SP600125(1PMV)在肺上皮細(xì)胞中,能阻斷AREG 誘導(dǎo)的c-Jun磷酸化及上皮-間質(zhì)轉(zhuǎn)化(EMT)過程[7];在HPDLSCs(牙周膜干細(xì)胞)中,SP600125可逆轉(zhuǎn)Wnt5a 對(duì)成骨分化的抑制作用[8];
SP600125(JNK Inhibitor II,AbMole,M2076)在BMSCs(骨髓間充質(zhì)干細(xì)胞)中,減輕TNF-α 誘導(dǎo)的p53、caspase-9/-3上調(diào),改善細(xì)胞遷移能力[9]。
SP600125(JNK Inhibitor II,AbMole,M2076)在動(dòng)物實(shí)驗(yàn)中,常通過腹腔注射(i.p.)給藥,少部分為腦室注射(i.c.v.)給藥,劑量多為10–50 mg/kg。例如,在RAG-2−/−小鼠A673肉瘤模型中,50 mg/kg劑量顯著抑制腫瘤生長(zhǎng)并降低VEGF表達(dá)與微血管密度(MVD),同時(shí)提高凋亡指數(shù)[10];在大鼠局灶性腦缺血再灌注(MCAO)模型中,i.c.v.給予SP600125可減輕腦梗死體積并改善行為異常[11];SP600125在心肌缺血再灌注損傷大鼠模型中,與Ulinastatin(烏司他。┞(lián)用可降低p-JNK表達(dá)并減少心肌細(xì)胞凋亡[12]。
綜合來看,
SP600125(JNK Inhibitor II,AbMole,M2076)作為JNK通路的關(guān)鍵工具化合物,在多種細(xì)胞系(包括SH-SY5Y、U2OS、PC12等)及小鼠、大鼠等動(dòng)物模型中,為解析JNK信號(hào)在細(xì)胞命運(yùn)決定、應(yīng)激響應(yīng)及組織穩(wěn)態(tài)維持中的作用提供了重要實(shí)驗(yàn)工具。
