Inferring the age and strength of mutations evolving under positive selection

Nicky Louise Ormond

A fundamental goal of population genetics is to determine and quantify the interplay of mutation, natural selection, genetic drift and migration in shaping allelic frequency changes that underpin evolution-ary change. In this dissertation, I present comput ...

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 ...

Viral RNA Degradation and Diffusion Act as a Bottleneck for the Influenza A Virus Infection Efficiency

Christian Sieben

After endocytic uptake, influenza viruses transit early endosomal compartments and eventually reach late endosomes. There, the viral glycoprotein hemagglutinin (HA) triggers fusion between endosomal and viral membrane, a critical step that leads to release ...

Hepatocyte Growth Factor-mediated satellite cells niche perturbation promotes development of distinct sarcoma subtypes

Andrea Ferrari, Michela Casanova

Embryonal Rhabdomyosarcoma (ERMS) and Undifferentiated Pleomorphic Sarcoma (UPS) are distinct sarcoma subtypes. Here we investigate the relevance of the satellite cell (SC) niche in sarcoma development by using Hepatocyte Growth Factor (HGF) to perturb the ...

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

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

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 ...

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 ...

An Approximate Markov Model for the Wright-Fisher Diffusion and Its Application to Time Series Data

Jeffrey David Jensen, Anna Ferrer Admetlla

The joint and accurate inference of selection and demography from genetic data is considered a particularly challenging question in population genetics, since both process may lead to very similar patterns of genetic diversity. However, additional informat ...

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 ...

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 ...
