一般描述
毒胡萝卜素(Thapsigargin)是一种愈创木内酯倍半萜内酯，是一种广泛使用的肌质网/内质网Ca2+ ATP酶(SERCA)抑制剂。它可激活内质网(ER)应激和未折叠蛋白质应答。 毒胡萝卜素是一种天然植化素，存在于地中海植物毒胡萝卜(Thapsia garganica)的根和果实中。毒胡萝卜素可使停滞翻译恢复并诱导冠状病毒(CoV)感染细胞内的代谢途径发生全蛋白质组变化。
应用
毒胡萝卜素已用作内质网（ER）应激诱导因子：
- 研究其对肝癌细胞中环化酶相关蛋白质2（CAP2）表达的影响
- 使用ARPE-19细胞（人视网膜色素上皮细胞）进行细胞活力测试
- 研究其对原发性肝细胞磷脂2（LCN2）糖基化的影响
- 研究细胞内质网 (ER) 钙消耗的后果
- 研究其对大鼠支持细胞中金属蛋白酶组织抑制剂-1 (TIMP-1) mRNA表达的影响
生化/生理作用
毒胡萝卜素是强有效的可穿透细胞的IP3-依赖型细胞内钙释放器。 它阻断由血管抑制素和内皮抑素诱导的细胞内Ca2+的瞬时增加。它也通过破坏细胞内游离Ca2+水平诱导细胞凋亡；并掺入进化学治疗前药的配方中。
