在細(xì)胞模型研究中,Ammonium tetrathiomolybdate(四硫代鉬酸鹽)在1.5 μM濃度下處理犬血管肉瘤細(xì)胞系DEN-HSA,表現(xiàn)出顯著的細(xì)胞毒性[4]。Ammonium tetrathiomolybdate在HepG2人肝癌細(xì)胞與HEK293人胚腎細(xì)胞中,以1 μM–10 mM的濃度梯度處理24小時可觀察到細(xì)胞特異性銅保留差異及氧化應(yīng)激反應(yīng)[5]。動物實驗方面,Ammonium tetrathiomolybdate(TTM)在C57BL/6小鼠膽管結(jié)扎纖維化模型中,每日0.9 mg/kg劑量干預(yù)可緩解纖維化進(jìn)程[6],此外,在野百合堿(Monocrotaline)誘導(dǎo)的肺纖維化綿羊模型中,Ammonium tetrathiomolybdate(TTM)干預(yù)可抑制血管生成與纖維化[7]。在TNBC(三陰性乳腺癌)小鼠模型中,口服Ammonium tetrathiomolybdate(TTM)能維持血清銅藍(lán)蛋白于8–17 mg/dL的水平,顯著抑制肺轉(zhuǎn)移、降低LOX活性及膠原交聯(lián)[8]。

AbMoel的
Ammonium tetrathiomolybdate(TTM,AbMole, M54856)在本研究中作為銅死亡的抑制劑,通過對照實驗以驗證 FOXJ1 基因?qū)m頸癌細(xì)胞銅死亡的調(diào)控作用。研究結(jié)果表明,F(xiàn)OXJ1基因過表達(dá)顯著抑制宮頸癌細(xì)胞增殖、侵襲和遷移,并促進(jìn)銅死亡,而TTM通過螯合銅離子,抑制了銅死亡過程,從而逆轉(zhuǎn)了FOXJ1過表達(dá)的腫瘤抑制作用。
