The frontier前沿概述

DNA is the only known information storage system that builds the reader it requires. For most of human history we could only watch what it wrote; in the last decade we have learned to rewrite single letters at single sites in living cells. Gene editing started in the 1970s with restriction enzymes — cellular 'scissors.' It took 40 more years for CRISPR-Cas9 to make those scissors programmable. In 2023, Casgevy became the first CRISPR therapy approved for human use, curing sickle cell disease — a one-shot intervention against a centuries-old killer.DNA 是已知唯一一种“自带读取器”的信息存储系统。在人类历史的绝大多数时间里，我们只能旁观它的书写；最近十年，我们学会了在活体细胞中、对单一位点、改写单一字母。基因编辑始于 1970 年代的限制性内切酶——细胞剪刀；又过了四十年，CRISPR-Cas9 把这把剪刀变为可编程。2023 年，Casgevy 成为首款获批人用的 CRISPR 疗法，治愈镰状细胞病——一次性击败一种数百年的死神。

State of the art今日状态

Beyond cut-and-paste, prime editing and base editing let researchers change single letters without breaking the double helix. In vivo delivery — editing cells while still in the body — is the active frontier. The agricultural and conservation edges are moving fast too: gene drives for malaria mosquitoes, drought-resistant wheat, blight-resistant chestnuts.在简单的剪贴之外，引物编辑与碱基编辑可在不剪断双螺旋的前提下改写单个字母。体内递送——细胞还在身体里时直接编辑——是活跃的前沿。农业与保育端进展也快：抗疟蚊的基因驱动、耐旱小麦、抗枯萎栗树。
