活体吗啉是一种很有前途的基因沉默工具。这些寡核苷酸类似物通过阻止翻译或前信使核糖核酸剪接而使基因暂时沉默。据报道,活体吗啡治疗的毒性很小或没有。然而,在我们实验室最近进行的一项研究中,用体内吗啉治疗小鼠导致了高死亡率。我们假设死亡是寡核苷酸杂交的结果,导致与体内树枝状大分子递送部分相关的阳离子电荷增加-吗啉。阳离子电荷增加了体内吗啡处理的全血中血液凝块的形成,这表明凝血可能导致死亡小鼠的心脏骤停。因此,我们研究了一些体内吗啉类药物增加死亡率的机制,并提出了减轻体内吗啡酚毒性的技术。
Vivo-morpholinos are a promising tool for gene silencing. These oligonucleotide analogs transiently silence genes by blocking either translation or pre-mRNA splicing. Little to no toxicity has been reported for vivo-morpholino treatment. However, in a recent study conducted in our lab, treatment of mice with vivo-morpholinos resulted in high mortality rates. We hypothesized that the deaths were the result of oligonucleotide hybridization, causing an increased cationic charge associated with the dendrimer delivery moiety of the vivo-morpholino. The cationic charge increased blood clot formation in whole blood treated with vivo-morpholinos, suggesting that clotting could have caused cardiac arrest in the deceased mice. Therefore, we investigate the mechanism by which some vivo-morpholinos increase mortality rates and propose techniques to alleviate vivo-morpholino toxicity.
