一些令人兴奋的生物学问题需要量化单个细胞中的数千种蛋白质。为了实现这一目标,我们开发了单细胞质谱蛋白质组学(SCoPE-MS),并验证了其基于蛋白质组识别不同人类癌细胞类型的能力。我们使用SCoPE-MS来量化分化小鼠胚胎干细胞中的一千多种蛋白质。单细胞蛋白质组使我们能够解构细胞群体并推断蛋白质丰度关系。单细胞蛋白质组和转录组之间的比较表明协调的mRNA和蛋白质的共变,但许多基因表现出功能协调和不同的监管模式在mRNA和蛋白质水平。本文的在线版本(10.1186/s13059-018-1547-5)包含补充材料,可供授权用户使用。
Some exciting biological questions require quantifying thousands of proteins in single cells. To achieve this goal, we develop Single Cell ProtEomics by Mass Spectrometry (SCoPE-MS) and validate its ability to identify distinct human cancer cell types based on their proteomes. We use SCoPE-MS to quantify over a thousand proteins in differentiating mouse embryonic stem cells. The single-cell proteomes enable us to deconstruct cell populations and infer protein abundance relationships. Comparison between single-cell proteomes and transcriptomes indicates coordinated mRNA and protein covariation, yet many genes exhibit functionally concerted and distinct regulatory patterns at the mRNA and the protein level.
