Coalescent Processes with Skewed Offspring Distributions and Nonequilibrium Demography

Jeffrey David Jensen, Sebastian Matuszewski

2018

The utility of fitness landscapes and big data for predicting evolution

NATURE PUBLISHING GROUP2018

The fitness landscape of the codon space across environments

Jeffrey David Jensen, Claudia Bank, Sebastian Matuszewski

Fitness landscapes map the relationship between genotypes and fitness. However, most fitness landscape studies ignore the genetic architecture imposed by the codon table and thereby neglect the potential role of synonymous mutations. To quantify the fitnes ...

Two sides of the same coin: A population genetics perspective on lethal mutagenesis and mutational meltdown

Jeffrey David Jensen, Claudia Bank, Nicky Louise Ormond, Sebastian Matuszewski

The extinction of RNA virus populations upon application of a mutagenic drug is frequently referred to as evidence for the existence of an error threshold, above which the population cannot sustain the mutational load. To explain the extinction process aft ...

On the Analysis of Intrahost and Interhost Viral Populations: Human Cytomegalovirus as a Case Study of Pitfalls and Expectations

Jeffrey David Jensen, Sebastian Matuszewski, Susanne Petra Pfeifer

Intrahost and interhost assessments of viral diversity are often treated as measures of separate and distinct evolutionary processes, with numerous investigations reporting seemingly incompatible results between the two. For example, in human cytomegalovir ...

The Combined Effect of Oseltamivir and Favipiravir on Influenza A Virus Evolution

Jeffrey David Jensen, Claudia Bank, Nicky Louise Ormond, Sebastian Matuszewski

Influenza virus inflicts a heavy death toll annually and resistance to existing antiviral drugs has generated interest in the development of agents with novel mechanisms of action. Favipiravir is an antiviral drug that acts by increasing the genome-wide mu ...

CRISPR-Cas9-mediated saturated mutagenesis screen predicts clinical drug resistance with improved accuracy

Jeffrey David Jensen, Sebastian Matuszewski

Developing tools to accurately predict the clinical prevalence of drug-resistant mutations is a key step toward generating more effective therapeutics. Here we describe a high-throughput CRISPR-Cas9-based saturated mutagenesis approach to generate comprehe ...

National Academy of Sciences2017

An experimental evaluation of drug-induced mutational meltdown as an antiviral treatment strategy

Hyunjin Shim, Jeffrey David Jensen, Claudia Bank, Matthieu Foll, Sebastian Matuszewski

The rapid evolution of drug resistance remains a critical public health concern. The treatment of influenza A virus (IAV) has proven particularly challenging, due to the ability of the virus to develop resistance against current antivirals and vaccines. He ...

Wiley-Blackwell2016

On the (un) predictability of a large intragenic fitness landscape

Jeffrey David Jensen, Claudia Bank, Sebastian Matuszewski

The study of fitness landscapes, which aims at mapping genotypes to fitness, is receiving ever-increasing attention. Novel experimental approaches combined with next-generation sequencing (NGS) methods enable accurate and extensive studies of the fitness e ...

National Academy of Sciences2016

A Statistical Guide to the Design of Deep Mutational Scanning Experiments

Jeffrey David Jensen, Claudia Bank, Sebastian Matuszewski

The characterization of the distribution of mutational effects is a key goal in evolutionary biology. Recently developed deep-sequencing approaches allow for accurate and simultaneous estimation of the fitness effects of hundreds of engineered mutations by ...

Detecting and Quantifying Changing Selection Intensities from Time-Sampled Polymorphism Data

Hyunjin Shim, Jeffrey David Jensen, Matthieu Foll, Stefan Jean Laurent, Sebastian Matuszewski

During his well-known debate with Fisher regarding the phenotypic dataset of Panaxia dominula, Wright suggested fluctuating selection as a potential explanation for the observed change in allele frequencies. This model has since been invoked in a number of ...

Catch Me if You Can: Adaptation from Standing Genetic Variation to a Moving Phenotypic Optimum

Sebastian Matuszewski

Adaptation lies at the heart of Darwinian evolution. Accordingly, numerous studies have tried to provide a formal framework for the description of the adaptive process. Of these, two complementary modeling approaches have emerged: While so-called adaptive- ...
