肺癌融合基因检测--陈巍学基因(20)

这节课程会和大家谈一下药明康德公司提供的、用NanoString来测肺癌中融合基因的方法。

用NanoString方法来检测肺癌融合基因,一次实验可以检测4种基因的融合突变,并且方便快捷。用NanoString与金标准FISH方法做对照实验,结果完全一致。是一种有前途的肿瘤靶向药物伴随诊断方法。

病毒的膜融合 - Stephen Harrison P2

本视频由科普中国和生物医学大讲堂出品

Stephen Harrison (Harvard) Part 2: Viral membrane fusion

Harrison begins his talk by asking why most non-enveloped viruses and some enveloped viruses are symmetrical in shape. He proceeds to show us lovely images of the structures obtained by x-ray crystallography of numerous viral coat proteins. Deciphering these structures allowed scientists to understand that viral coat proteins form multimers, such as dimers and pentamers, which in turn interact with a scaffold that ensures that the coat proteins are correctly placed. This arrangement results in symmetrically shaped viruses.

In Part 1, Harrison also explains that enveloped viruses infect cells by inducing the fusion of the viral and host cell membranes. He delves deeper into the molecular mechanism of membrane fusion driven by the hemagglutinin or HA protein of the influenza virus in Part 2 of his talk.

Non-enveloped viruses, on the other hand, must enter cells by a mechanism other than membrane fusion. This is the focus of Part 3. Using rotavirus as a model, Harrison and his colleagues have used a combination of Xray crystallography and electron cryomicroscopy to decipher how the spike protein on the viral surface changes its conformation and perforates the cell membrane allowing the virus to enter the cell.
