Cancer–immune coevolution dictated by antigenic mutation accumulation [PDF]

open access: yeseLife
The immune system is one of the first lines of defence against cancer. When effector cells attempt to suppress tumour, cancer cells can evolve methods of escape or inhibition.

What can we infer about mutation calling by using time‐series mutation accumulation data and a Bayesian Mutation Finder? [PDF]

open access: yesEcology and Evolution
Accurate estimates of mutation rates derived from genome‐wide mutation accumulation (MA) data are fundamental to understanding basic evolutionary processes. The rapidly improving high‐throughput sequencing technologies provide unprecedented opportunities

Mutation accumulation in Tetrahymena [PDF]

open access: yesBMC Evolutionary Biology, 2010
Background The rate and fitness effects of mutations are key in understanding the evolution of every species. Traditionally, these parameters are estimated in mutation accumulation experiments where replicate lines are propagated in conditions that allow

Are mutations usually deleterious? A perspective on the fitness effects of mutation accumulation. [PDF]

open access: yesEvol Ecol, 2022
All adaptive alleles in existence today began as mutations, but a common view in ecology, evolution, and genetics is that non-neutral mutations are much more likely to be deleterious than beneficial and will be removed by purifying selection. By dramatically limiting the effectiveness of selection in experimental mutation accumulation lines, multiple ...

Mutation Accumulation in an Asexual Relative of Arabidopsis. [PDF]

open access: yesPLoS Genetics, 2017
Asexual populations experience weaker responses to natural selection, which causes deleterious mutations to accumulate over time. Additionally, stochastic loss of individuals free of deleterious mutations can lead to an irreversible increase in ...

Causes of variability in estimates of mutational variance from mutation accumulation experiments. [PDF]

open access: yesGenetics, 2022
ABSTRACT Characteristics of the new phenotypic variation introduced via mutation have broad implications in evolutionary and medical genetics. Standardised estimates of this mutational variance, V M , span two orders of ...

Identification of natural product 3, 5-diiodotyrosine as APOBEC3B inhibitor to prevent somatic mutation accumulation and cancer progression [PDF]

open access: yesJournal for ImmunoTherapy of Cancer, 2022
Background The development of cancer is largely dependent on the accumulation of somatic mutations, indicating the potential to develop cancer chemoprevention agents targeting mutation drivers.

Fitness Effects of Mutations: An Assessment of PROVEAN Predictions Using Mutation Accumulation Data. [PDF]

open access: yesGenome Biol Evol, 2022
Abstract Predicting fitness in natural populations is a major challenge in biology. It may be possible to leverage fast-accumulating genomic data sets to infer the fitness effects of mutant alleles, allowing evolutionary questions to be addressed in any organism. In this paper, we investigate the utility of one such tool, called PROVEAN.

Quantifying natural seasonal variation in mutation parameters with mutation accumulation lines [PDF]

open access: yesEcology and Evolution, 2018
AbstractMutations create novel genetic variants, but their contribution to variation in fitness and other phenotypes may depend on environmental conditions. Furthermore, natural environments may be highly heterogeneous. We assessed phenotypes associated with survival and reproductive success in over 30,000 plants representing 100 mutation accumulation ...

Selection bias in mutation accumulation [PDF]

open access: yesEvolution, 2021
Abstract Mutation accumulation (MA) experiments, in which de novo mutations are sampled and subsequently characterized, are an essential tool in understanding the processes underlying evolution.
