Female Blow Flies As Vertebrate Resource Indicators [PDF]

open access: yes, 2019
Rapid vertebrate diversity evaluation is invaluable for monitoring changing ecosystems worldwide. Wild blow flies naturally recover DNA and chemical signatures from animal carcasses and feces.

Going nuclear: gene family evolution and vertebrate phylogeny reconciled [PDF]

open access: yes, 2002
Gene duplications have been common throughout vertebrate evolution, introducing paralogy and so complicating phylogenctic inference from nuclear genes.

De novo synthesis of a sunscreen compound in vertebrates

open access: yeseLife, 2015
Ultraviolet-protective compounds, such as mycosporine-like amino acids (MAAs) and related gadusols produced by some bacteria, fungi, algae, and marine invertebrates, are critical for the survival of reef-building corals and other marine organisms exposed

Delving into Vertebrate Serpins for Understanding their Evolution [PDF]

open access: yes, 2009
The superfamily of serine proteinase inhibitors (serpins) is involved in an array of fundamental biological processes such as blood coagulation, cell differentiation, cell migration, complement activation, embryo implantation, fibrinolysis, angiogenesis,

Targets and Effects of Yessotoxin, Okadaic Acid and Palytoxin: A Differential Review

open access: yesMarine Drugs, 2010
In this review, we focus on processes, organs and systems targeted by the marine toxins yessotoxin (YTX), okadaic acid (OA) and palytoxin (PTX). The effects of YTX and their basis are analyzed from data collected in the mollusc Mytilus galloprovincialis,

Comparative Analyses of Vertebrate Gut Microbiomes Reveal Convergence between Birds and Bats

open access: yesmBio, 2020
Diet and host phylogeny drive the taxonomic and functional contents of the gut microbiome in mammals, yet it is unknown whether these patterns hold across all vertebrate lineages.

Insights from the Structure of Estrogen Receptor into the Evolution of Estrogens: Implications for Endocrine Disruption [PDF]

open access: yes, 2011
In the last decade, there has been important progress in understanding the origins and evolution of receptors for adrenal steroids (aldosterone, cortisol) and sex steroids (estradiol, progesterone, testosterone) due to the sequencing of genomes from ...

Ancient Pbx-Hox signatures define hundreds of vertebrate developmental enhancers [PDF]

open access: yes, 2011
Background: Gene regulation through cis-regulatory elements plays a crucial role in development and disease. A major aim of the post-genomic era is to be able to read the function of cis-regulatory elements through scrutiny of their DNA sequence ...

Current ecological understanding of fungal-like pathogens of fish: what lies beneath?

open access: yesFrontiers in Microbiology, 2014
Despite increasingly sophisticated microbiological techniques, and long after the first discovery of microbes, basic knowledge is still lacking to fully appreciate the ecological importance of microbial parasites in fish. This is likely due to the nature

Scaling Laws for Mitotic Chromosomes

open access: yesFrontiers in Cell and Developmental Biology, 2021
During mitosis in higher eukaryotes, each chromosome condenses into a pair of rod-shaped chromatids. This process is co-regulated by the activity of several gene families, and the underlying biophysics remains poorly understood.
