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 ...

Surface Topography and Ultrastructure of the Spectacular Cells in the Eyes of Land and Sea Snakes (Squamata, Reptilia): Functional Adaptations of Micro‐Ornamentation

open access: yesJournal of Morphology, Volume 286, Issue 9, September 2025.
ABSTRACT Although the surface micro‐ornamentation of the scales within the skin of snakes has been the subject of many previous studies, there has been little work done on the spectacle, a protective (keratinised) goggle separated from the underlying cornea by a sub‐spectacular space. The surface ultrastructure of the “Oberhäutchen” of the spectacle is

Single‐Cell Sequencing: A Sharp Sword for Deciphering Biological Innovations and Evolutionary Adaptations in Lower Vertebrates and Invertebrates

open access: yesReviews in Aquaculture, Volume 17, Issue 4, September 2025.
Single‐cell sequencing sheds light on cellular diversity, development, and immune evolution in fish and invertebrates, offering new insights into environmental adaptation and evolutionary biology. ABSTRACT Single‐cell sequencing (SCS) technology has revolutionized the study of cellular heterogeneity by enabling the exploration of biological processes ...

Somatic diversification of variable lymphocyte receptors in the agnathan sea lamprey [PDF]

open access: yesNature, 2004
Although jawless vertebrates are apparently capable of adaptive immune responses, they have not been found to possess the recombinatorial antigen receptors shared by all jawed vertebrates. Our search for the phylogenetic roots of adaptive immunity in the lamprey has instead identified a new type of variable lymphocyte receptors (VLRs) composed of ...

Defining mononuclear phagocyte subset homology across several distant warm-blooded vertebrates through comparative transcriptomics

open access: yesFrontiers in Immunology, 2015
Mononuclear phagocytes are organized in a complex system of ontogenically and functionally-distinct subsets, that has been best described in mouse and to some extent in human. Identification of homologous mononuclear phagocyte subsets in other vertebrate

Fish Evo‐Devo: Moving Toward Species‐Specific and Knowledge‐Based Interactome

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 3, Page 158-168, May 2025.
Gaining knowledge‐based, fish‐specific interactomes is crucial in Evo‐Devo biology for uncovering how gene networks drive the unique adaptations and diversity of fish, the most diverse vertebrates. These interactomes also provide insights into conserved and derived mechanisms of vertebrate evolution, highlighting the molecular basis of key evolutionary

Exploration and Analysis of Jagged-Notch Signaling in Lamprey Pharyngeal Arches [PDF]

open access: yes, 2013
The development of the jaw was an important event in vertebrate evolution that led to their success as top predators, but little is known about the molecular mechanisms behind its development.

The Neural Crest Migrating into the Twenty-First Century [PDF]

open access: yes, 2016
From the initial discovery of the neural crest over 150 years ago to the seminal studies of Le Douarin and colleagues in the latter part of the twentieth century, understanding of the neural crest has moved from the descriptive to the experimental.

Invertebrate Bile Acid‐Sensitive Ion Channels and Their Emergence in Bilateria

open access: yesThe FASEB Journal, Volume 39, Issue 8, 30 April 2025.
This graphical abstract presents the evolutionary distribution and functional characteristics of bile acid‐sensing ion channels (BASICs) across bilaterians. A phylogenetic tree illustrates the presence of BASICs in diverse groups, extending beyond previously established mammalian findings.
