Function and evolution of microRNAs in eusocial Hymenoptera

open access: yesFrontiers in Genetics, 2015
The emergence of eusociality (true sociality) in several insect lineages represents one of the most successful evolutionary adaptations in the animal kingdom in terms of species richness and global biomass.

Evidence for the Accumulation of Nonsynonymous Mutations and Favorable Pleiotropic Alleles During Wheat Breeding

open access: yesG3: Genes, Genomes, Genetics, 2020
Plant breeding leads to the genetic improvement of target traits by selecting a small number of genotypes from among typically large numbers of candidate genotypes after careful evaluation.

What is Antagonistic Pleiotropy?

open access: yes, 2018
Antagonistic Pleiotropy has been the dominant theory for evolution of aging since it was first proposed 60 years ago. Indeed, examples of pleiotropy have been observed, but there are also many examples of mutations that lead to longer lifespan without ...

Pleiotropic mutations can rapidly evolve to directly benefit self and cooperative partner despite unfavorable conditions

open access: yeseLife, 2021
Cooperation, paying a cost to benefit others, is widespread. Cooperation can be promoted by pleiotropic ‘win-win’ mutations which directly benefit self (self-serving) and partner (partner-serving).

Emerging infectious disease selects for darker plumage coloration in greenfinches

open access: yesFrontiers in Ecology and Evolution, 2014
Outbreaks of emerging infectious disease offer a unique chance to study viability selection in action in short time windows. Finch trichomonosis, caused by a protozoan Trichomonas gallinae emerged in Great Britain in 2005 and led to epidemic mortality ...

The evolution of pleiotropy promotes cooperation.

open access: yes, 2022
Heatmaps show average trait values among the global population of cells (across all groups) at steady state in our model. Results are shown for 3 group sizes (increasing from top to bottom).

Pleiotropy as the Mechanism for Evolving Novelty: Same Signal, Different Result

open access: yesBiology, 2015
In contrast to the probabilistic way of thinking about pleiotropy as the random expression of a single gene that generates two or more distinct phenotypic traits, it is actually a deterministic consequence of the evolution of complex physiology from the ...

Establishing plausibility of cardiovascular adverse effects of immunotherapies using Mendelian randomisation

open access: yesFrontiers in Cardiovascular Medicine, 2023
Immune checkpoint inhibitors (ICIs) and Janus kinase inhibitors (JAKis) have raised concerns over serious unexpected cardiovascular adverse events.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
