1958年，弗朗西斯・克里克提出了中心法则，提出遗传信息从 DNA 转录为 RNA，再经翻译指导蛋白质合成，随后蛋白质参与生命活动这一流程，看似一气呵成，实则存在问题。 若仔细观察，便会发觉此流程不够简洁，RNA 的存在略显累赘。毕竟，越简单的系统往往越高效、越易实现，繁琐的系统则耗能多且不易形成。 从结构看，RNA 与 DNA ...

研究团队发现，细胞在暴露于紫外线后首先响应的是RNA损伤，而这正是触发细胞死亡和皮肤炎症的原因。当ZAK基因被去除后，这些反应也随之消失。为此他们培育了一种缺乏ZAK基因的基因编辑小鼠。与正常小鼠相比，这些小鼠在暴露于紫外线后的头几个小时里，皮肤炎症显著减轻。这意味着ZAK在皮肤对紫外线诱导损伤的响应中发挥着关键作用。

最新研究揭示，导致日晒伤急性反应的根源在于RNA受损，而非传统认知中的DNA破坏，为相关治疗提供了全新视角。 长期暴露在阳光下又缺乏足够保护，皮肤常会红肿灼痛，像一只即将上桌的龙虾。 传统观点认为，皮肤的炎症反应源于组织DNA受损后引发的一系列连锁效应。然而，最新针对小鼠和人类皮肤细胞的研究发现，晒伤的初始反应与以往预期截然不同。 “教科书告诉我们，晒伤是由DNA受损引起的细胞死亡和炎症，但这项研 ...
