探索治疗方法

First, we need to understand which mutations lead to a gain of function of the protein (GOF) and which ones to a loss of function (LOF). This is because the therapeutic strategies are opposite: stop the mutated protein for GOF, and increase the healthy one for LOF. 

We aim to pursue the following strategies to find treatments:

  1. Target AGO1 and AGO2 proteins: repurposing existing drugs or finding novel small-molecule drugs

  2. Target AGO1 and AGO2 RNA: antisense oligonucleotides to upregulate activity for LOF (splicing) or shut down the mutated protein for GOF

  3. Target AGO1 and AGO2 DNA: gene replacement therapy (LOF only) and gene editing

A better understanding of a) disease mechanisms and b) how the disease presents itself gained from our earlier phases will strongly guide the development of therapeutic approaches.

Learn more on this page about the three approaches and why we believe in them.

As we don't know yet strategy will work best, we will go after these strategies in parallel.

The science and medicine are so complex that it's just impossible to know in advance which therapies will be safe and effective. I would suggest a portfolio approach, even for a single disease.

治疗策略

蛋白质疗法

小分子药物 增加或减少AGO1/2的产生或活性,从筛选已批准或已开发的药物开始,以确定是否存在脱靶效应

核糖核酸疗法

如果是功能增益突变,则关闭突变的 AGO1/2;如果是功能缺失突变,则使用剪接反义寡核苷酸 (ASO) 或调节元件 ASO 来上调健康 AGO1/2 的生成

DNA疗法

提供AGO1/2的功能拷贝(AAV介导的基因疗法) 或纠正突变 (CRISPR碱基编辑)。前者只适用于功能缺失突变。
