Evolutionary genomics and adaptive evolution of the Hedgehog gene family (Shh, Ihh and Dhh) in vertebrates.
(PLoS One, 2014)
The Hedgehog (Hh) gene family codes for a class of secreted proteins composed of two active domains that act as signalling molecules during embryo development, namely for the development of the nervous and skeletal systems ...
Phylogenomic analyses data of the avian phylogenomics project.
BACKGROUND: Determining the evolutionary relationships among the major lineages of extant birds has been one of the biggest challenges in systematic biology. To address this challenge, we assembled or collected the genomes ...
Olfactory Receptor Subgenomes Linked with Broad Ecological Adaptations in Sauropsida.
(Mol Biol Evol, 2015-11)
Olfactory receptors (ORs) govern a prime sensory function. Extant birds have distinct olfactory abilities, but the molecular mechanisms underlining diversification and specialization remain mostly unknown. We explored OR ...
Avian genomes. A flock of genomes. Introduction.
Identification of dopamine receptors across the extant avian family tree and analysis with other clades uncovers a polyploid expansion among vertebrates.
(Front Neurosci, 2015)
Dopamine is an important central nervous system transmitter that functions through two classes of receptors (D1 and D2) to influence a diverse range of biological processes in vertebrates. With roles in regulating neural ...
Surviving as an underrepresented minority scientist in a majority environment.
(Mol Biol Cell, 2015-11-01)
I believe the evidence will show that the science we conduct and discoveries we make are influenced by our cultural experience, whether they be positive, negative, or neutral. I grew up as a person of color in the United ...
Zebra finches communicate with each other in ways that are more complex than previously thought.
Brain evolution by brain pathway duplication.
(Philos Trans R Soc Lond B Biol Sci, 2015-12-19)
Understanding the mechanisms of evolution of brain pathways for complex behaviours is still in its infancy. Making further advances requires a deeper understanding of brain homologies, novelties and analogies. It also requires ...
The Origin and Diversification of Birds.
(Curr Biol, 2015-10-05)
Birds are one of the most recognizable and diverse groups of modern vertebrates. Over the past two decades, a wealth of new fossil discoveries and phylogenetic and macroevolutionary studies has transformed our understanding ...
Transsynaptic Tracing from Peripheral Targets with Pseudorabies Virus Followed by Cholera Toxin and Biotinylated Dextran Amines Double Labeling.
(J Vis Exp, 2015-09-14)
Transsynaptic tracing has become a powerful tool used to analyze central efferents that regulate peripheral targets through multi-synaptic circuits. This approach has been most extensively used in the brain by utilizing ...
