高通量生物和临床数据中有理数上的类分形分布

Fractal-like Distributions over the Rational Numbers in High-throughput Biological and Clinical Data

Vladimir Trifonov, Laura Pasqualucci, Riccardo Dalla-Favera, Raul Rabadan

摘要:

在提取和处理生物和临床数据的最新发展允许定量方法来研究生命系统。高通量测序、表达谱、蛋白质组学和电子健康记录是这些技术的一些例子。从这些技术中提取有意义的信息需要仔细分析它们产生的大量数据。在这篇文章中,我们提出了一组在分析此类数据时经常出现的分布。这些分布呈现出一些有趣的特征:它们在有理数中是不连续的,但在无理数中是连续的,并且具有一定的自相似(分形)结构。我们在这里介绍的第一组例子来自高通量测序实验。在这里,自相似分布作为测序技术错误率评估和致瘤基因组改变鉴定的一部分出现。其他例子是从风险因素评估和分析相对疾病患病率和并发症,因为这些出现在电子临床数据。这些分布也与肿瘤中亚克隆群体的鉴定和传染病进化的研究有关,更确切地说,与病毒群体的准种和宿主内多样性的研究有关。

英文摘要:

Recent developments in extracting and processing biological and clinical data are allowing quantitative approaches to studying living systems. High-throughput sequencing, expression profiles, proteomics, and electronic health records are some examples of such technologies. Extracting meaningful information from those technologies requires careful analysis of the large volumes of data they produce. In this note, we present a set of distributions that commonly appear in the analysis of such data. These distributions present some interesting features: they are discontinuous in the rational numbers, but continuous in the irrational numbers, and possess a certain self-similar (fractal-like) structure. The first set of examples which we present here are drawn from a high-throughput sequencing experiment. Here, the self-similar distributions appear as part of the evaluation of the error rate of the sequencing technology and the identification of tumorogenic genomic alterations. The other examples are obtained from risk factor evaluation and analysis of relative disease prevalence and co-mordbidity as these appear in electronic clinical data. The distributions are also relevant to identification of subclonal populations in tumors and the study of the evolution of infectious diseases, and more precisely the study of quasi-species and intrahost diversity of viral populations.
