在突变空间中模拟基因组和种群:以HIV耐药性的进化为例

Simulating Genomes and Populations in the Mutation Space: An example with the evolution of HIV drug resistance

Antonio Carvajal-Rodriguez

摘要:

当模拟不同进化遗传模型下的生物种群时,可以遵循向后或向前策略。反向模拟,也称为基于聚结的模拟,在计算上非常有效。然而,这个框架施加了一些限制,向前模拟没有。在这项工作中,提出了一种新的简单而有效的模型来执行人口和/或基因组的前向模拟。其基本思想认为个体是该个体与参考或共有基因型之间的差异(突变)。因此,该个体不再由其完整序列或基因型代表。一个新的模型相对于一个更经典的前一个效率的例子被证明。本实施例使用B_FR. HXB 2参考序列模拟HIV抗性的进化,以研究已知的对齐多夫定和去羟肌苷药物的抗性突变体的出现

英文摘要:

When simulating biological populations under different evolutionary genetic models, backward or forward strategies can be followed. Backward simulations, also called coalescent-based simulations, are computationally very efficient. However, this framework imposes several limitations that forward simulation does not. In this work, a new simple and efficient model to perform forward simulation of populations and/or genomes is proposed. The basic idea considers an individual as the differences (mutations) between this individual and a reference or consensus genotype. Thus, this individual is no longer represented by its complete sequence or genotype. An example of the efficiency of the new model with respect to a more classical forward one is demonstrated. This example models the evolution of HIV resistance using the B_FR.HXB2 reference sequence to study the emergence of known resistance mutants to Zidovudine and Didanosine drugs
