Cell：代谢减缓50%可抵消特定致死突变的不利影响
代谢减缓 可抵消 特定致死突变 不利影响
2019/8/28
近期Cell杂志上发布了一项颠覆认知的新研究。来自美国西北大学的科学家们发现，降低果蝇的代谢水平可以避免某些突变表型的出现，甚至可以完全绕过致死突变的不利影响。该研究发现，降低代谢竟然能让完全没有microRNA的果蝇正常发育到成虫。论文作者表示：“这颠覆了我们所知的一切发育范式。”研究者提出，这是由于基因网络内部的“反馈控制”。当新陈代谢减缓，机体就有了更多的时间去纠正错误。这些基因突变的果蝇在...
近日，美国贝勒医学院及太平洋西北国家实验室的科学家们利用基因组蛋白组学相结合的分析技术首次对人类结肠癌的蛋白基因组进行了详尽的分析，全面剖析了结直肠癌相关生物标志物、药物靶点和肿瘤抗原，并在Cell杂志上发表题为“Proteogenomic Analysis of Human Colon Cancer Reveals New Therapeutic Opportunities”的文章。
