Genes of the serotonergic and dopaminergic pathways and their interaction affect the expression of Behavioural and Psychological Symptoms in Dementia (BPSD). [PDF]

open access: yes, 2009
Although there is evidence for the involvement of genes of serotonergic and dopaminergic systems in the manifestation of the Behavioural and Psychological Symptoms in Dementia (BPSD), genetic association studies are contradictory.

Extensive behavioural divergence following colonisation of the freshwater environment in threespine sticklebacks.

open access: yesPLoS ONE, 2014
Colonisation of novel environments means facing new ecological challenges often resulting in the evolution of striking divergence in phenotypes.

Phenotypic plasticity of a cooperative behaviour in bacteria

open access: yesJournal of Evolutionary Biology, 2009
AbstractThere is strong evidence that natural selection can favour phenotypic plasticity as a mechanism to maximize fitness in animals. Here, we aim to investigate phenotypic plasticity of a cooperative trait in bacteria – the production of an iron‐scavenging molecule (pyoverdin) by Pseudomonas aeruginosa.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Behavioural and physiological responses to stressors in sheep with temperament classified by genotype or phenotype

open access: yesScientific Reports
The single nucleotide polymorphism (SNP) rs107856856, located in the tryptophan hydroxylase-2 gene, is associated with the behavioural phenotype for sheep temperament measured at weaning. Here, we tested the association between that SNP and physiological

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

The behavioural and cognitive phenotype of Smith-Magenis syndrome [PDF]

open access: yes, 2012
Background: Attention-seeking and impulsivity are reported to be problematic in Smith-Magenis syndrome (SMS) and have been linked to other challenging behaviours including self-injury and aggression.

Flexible males, proactive females: increased boldness/exploration damping with time in male but not female colonists

open access: yesRoyal Society Open Science
Individuals colonizing new areas during range expansion encounter challenging and unfamiliar environments, suggesting that colonists should differ in behavioural traits from residents of source populations.

Effect on adherence to nicotine replacement therapy of informing smokers their dose is determined by their genotype: a randomised controlled trial.

open access: yesPLoS ONE, 2012
BackgroundThe behavioural impact of pharmacogenomics is untested. We tested two hypotheses concerning the behavioural impact of informing smokers their oral dose of NRT is tailored to analysis of DNA.Methods and findingsWe conducted an RCT with smokers ...
