这项新研究的核心是称为毒性外显子（poison exon）的微小遗传元件，这是大自然自己的蛋白生产“开关”。当这些外显子包含在RNA信息中时，它们会在蛋白形成之前触发其破坏，从而防止有害的细胞活动。在健康细胞中，毒性外显子调节关键蛋白的水平，控制遗传机制。但在癌症中，这种安全机制经常失效。

A study reveals how cancer disrupts RNA splicing and presents a potential therapy using antisense oligonucleotides to target ...

Researchers have discovered that cancer cells suppress 'poison exons' -- genetic elements that act as an off switch for protein production -- in a key gene called TRA2 , promoting tumor growth. By ...

Scientists from The Jackson Laboratory and UConn Health found that cancer cells disrupt poison exons, leading to tumor growth ...

They found their answer in antisense oligonucleotides (ASOs)—synthetic RNA fragments that can be designed to increase poison exon inclusion in specific ways. When introduced into cancer cells ...
