A Balance between Inhibitor Binding and Substrate Processing Confers Influenza Drug Resistance

Jeffrey David Jensen, Claudia Bank, Li Jiang

The therapeutic benefits of the neuraminidase (NA) inhibitor oseltamivir are dampened by the emergence of drug resistance mutations in influenza A virus (IAV). To investigate the mechanistic features that underlie resistance, we developed an approach to qu ...

The population genomics of rapid adaptation: disentangling signatures of selection and demography in white sands lizards

Jeffrey David Jensen, Nicky Louise Ormond, Stefan Jean Laurent, Susanne Petra Pfeifer

Understanding the process of adaptation during rapid environmental change remains one of the central focal points of evolutionary biology. The recently formed White Sands system of southern New Mexico offers an outstanding example of rapid adaptation, with ...

The Impact of Linked Selection in Chimpanzees: A Comparative Study

Jeffrey David Jensen, Susanne Petra Pfeifer

Levels of nucleotide diversity vary greatly across the genomes of most species owing to multiple factors. These include variation in the underlying mutation rates, as well as the effects of both direct and linked selection. Fundamental to interpreting the ...

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 ...

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 ...

The consequences of not accounting for background selection in demographic inference

Jeffrey David Jensen, Gregory Bruce Ewing

Recently, there has been increased awareness of the role of background selection (BGS) in both data analysis and modelling advances. However, BGS is still difficult to take into account because of tractability issues with simulations and difficulty with no ...

On the relative roles of background selection and genetic hitchhiking in shaping human cytomegalovirus genetic diversity

Jeffrey David Jensen

A central focus of population genetics has been examining the contribution of selective and neutral processes in shaping patterns of intraspecies diversity. In terms of selection specifically, surveys of higher organisms have shown considerable variation i ...

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 ...

Molecular Basis for Differential Patterns of Drug Resistance in Influenza N1 and N2 Neuraminidase

Jeffrey David Jensen

Neuraminidase (NA) inhibitors are used for the prevention and treatment of influenza A virus infections. Two subtypes of NA, N1 and N2, predominate in viruses that infect humans, but differential patterns of drug resistance have emerged in each subtype des ...

The Genomic Signature of Population Reconnection Following Isolation: From Theory to HIV

Séverine Vuilleumier Varisco, Amalio Telenti, Jeffrey David Jensen

Ease of worldwide travel provides increased opportunities for organisms not only to colonize new environments but also to encounter related but diverged populations. Such events of reconnection and secondary contact of previously isolated populations are w ...

A Systematic Survey of an Intragenic Epistatic Landscape

Jeffrey David Jensen, Claudia Bank

Mutations are the source of evolutionary variation. The interactions of multiple mutations can have important effects on fitness and evolutionary trajectories. We have recently described the distribution of fitness effects of all single mutations for a nin ...

Limits and patterns of cytomegalovirus genomic diversity in humans

Jeffrey David Jensen, Cornelia Pokalyuk

Human cytomegalovirus (HCMV) exhibits surprisingly high genomic diversity during natural infection although little is known about the limits or patterns of HCMV diversity among humans. To address this deficiency, we analyzed genomic diversity among congeni ...

WFABC: a Wright-Fisher ABC-based approach for inferring effective population sizes and selection coefficients from time-sampled data

Hyunjin Shim, Jeffrey David Jensen, Matthieu Foll

With novel developments in sequencing technologies, time-sampled data are becoming more available and accessible. Naturally, there have been efforts in parallel to infer population genetic parameters from these data sets. Here, we compare and analyse four ...

Positive Selection Drives Preferred Segment Combinations during Influenza Virus Reassortment

Jeffrey David Jensen, Matthieu Foll

Influenza A virus (IAV) has a segmented genome that allows for the exchange of genome segments between different strains. This reassortment accelerates evolution by breaking linkage, helping IAV cross species barriers to potentially create highly virulent ...

Worldwide Population Structure, Long-Term Demography, and Local Adaptation of Helicobacter pylori

Jeffrey David Jensen, Matthieu Foll, Valeria Montano

Helicobacter pylori is an important human pathogen associated with serious gastric diseases. Owing to its medical importance and close relationship with its human host, understanding genomic patterns of global and local adaptation in H. pylori may be of pa ...

Evolution of the Influenza A Virus Genome during Development of Oseltamivir Resistance In Vitro

Jeffrey David Jensen

Influenza A virus (IAV) is a major cause of morbidity and mortality throughout the world. Current antiviral therapies include oseltamivir, a neuraminidase inhibitor that prevents the release of nascent viral particles from infected cells. However, the IAV ...

Inferring the Evolutionary History of Primate microRNA Binding Sites: Overcoming Motif Counting Biases

Jeffrey David Jensen, Feng Gao

The first microRNAs (miRNAs) were identified as essential, conserved regulators of gene expression, targeting the same genes across nearly all bilaterians. However, there are also prominent examples of conserved miRNAs whose functions appear to have shifte ...

Influenza Virus Drug Resistance: A Time-Sampled Population Genetics Perspective

Hyunjin Shim, Jeffrey David Jensen, Claudia Bank, Gregory Bruce Ewing, Matthieu Foll, Anna Ferrer Admetlla

Author Summary In recent years, considerable attention has been given to the evolution of drug resistance in the influenza A H1N1 strain. As a major annual cause of morbidity and mortality, combined with the rapid global spread of drug resistance, influenz ...

Human cytomegalovirus intrahost evolution - a new avenue for understanding and controlling herpesvirus infections

Jeffrey David Jensen

Human cytomegalovirus (HCMV) is exquisitely adapted to the human host, and much research has focused on its evolution over long timescales spanning millennia. Here, we review recent data exploring the evolution of the virus on much shorter timescales, on t ...
