Regional and aging-specific cellular architecture of non-human primate brains

open access: yesGenome Medicine
Background Deciphering the functionality and dynamics of brain networks across different regions and age groups in non-human primates (NHPs) is crucial for understanding the evolution of human cognition as well as the processes underlying brain ...

Object-translocation induces event coding in the rat hippocampus

open access: yesCommunications Biology
Episodic memory is the ability to recall personally experienced events that are situated within specific spatial contexts. Within a navigation environment, salient objects can function as landmarks, and interactions with them can be encoded as distinct ...

A high-quality genome assembly of the Spectacled Fulvetta (Fulvetta ruficapilla) endemic to China

open access: yesScientific Data
The Spectacled Fulvetta (Fulvetta ruficapilla) is the type species of Fulvetta, an evolutionarily distinct group whose species show a high degree of sympatry in distribution and phenotypic convergence.

NEK4 modulates circadian fluctuations of emotional behaviors and synaptogenesis in male mice

open access: yesNature Communications
GWASs have linked the 3p21.1 locus, which is associated with the expression levels of NEK4, to bipolar disorder. Here, we use integrative analyses of GWAS statistics and eQTL annotations to establish that elevated NEK4 expression in the hippocampus is ...

The nk model and population genetics [PDF]

open access: yesJournal of Theoretical Biology, 2005
The nk model of fitness interactions is examined. This model has been used by previous authors to investigate the effects of fitness epistasis on substitution dynamics in molecular evolution, and to make broader claims about the importance of epistasis. To examine these claims, an infinite-allele approximation is introduced.

The first chromosome-level genome of the stag beetle Dorcus hopei Saunders, 1854 (Coleoptera: Lucanidae)

open access: yesScientific Data
Stag beetles (Coleoptera: Lucanidae) represent a significant saproxylic assemblage in forest ecosystems and are noted for their enlarged mandibles and male polymorphism.

Multiscale spatial dependency of small mammal diversity patterns and their determinants

open access: yesEcosphere
Animals perceive their ecosystems at multiple spatial scales such that the pattern–process relationships that determine their ecological and evolutionary opportunities are also spatially variable.

Animal models with group-specific additive genetic variances: extending genetic group models [PDF]

open access: yesGenetics Selection Evolution, 2018
Abstract1.Theanimal modelis a key tool in quantitative genetics and has been used extensively to estimate fundamental parameters, such as additive genetic variance, heritability, or inbreeding effects. An implicit assumption of animal models is that all founder individuals derive from a single population.

A Genetic Porcine Model of Cancer

open access: yesPLOS ONE, 2015
The large size of the pig and its similarity in anatomy, physiology, metabolism, and genetics to humans make it an ideal platform to develop a genetically defined, large animal model of cancer. To this end, we created a transgenic "oncopig" line encoding Cre recombinase inducible porcine transgenes encoding KRASG12D and TP53R167H, which represent a ...

Whole-genome DNA methylomes of tree shrew brains reveal conserved and divergent roles of DNA methylation on sex chromosome regulation

open access: yesBMC Biology
Background The tree shrew (Tupaia belangeri) is a promising emerging model organism in biomedical studies, notably due to their evolutionary proximity to primates.
