Les phosphoprotéines sécrétées liant le calcium (SCPP) impliquées dans la formation de l'émail dentaire : expression chez le lézard Anolis carolinensis et évolution chez les amniotes [PDF]

open access: yes, 2015
Enamel formation requires the involvement of secretory calcium-binding phosphoproteins. Three of them, amelogenin (AMEL), ameloblastin (AMBN) and enamelin (ENAM), have been extensively studied in mammals.

Hand and foot pressures in the aye-aye (Daubentonia madagascariensis) reveal novel biomechanical trade-offs required for walking on gracile digits [PDF]

open access: yes, 2010
Arboreal animals with prehensile hands must balance the complex demands of bone strength, grasping and manipulation. An informative example of this problem is that of the aye-aye (Daubentonia madagascariensis), a rare lemuriform primate that is unusual ...

Gene Duplication and Alternative Splicing as Evolutionary Drivers of Proteome Specialization

open access: yesBioEssays, Volume 47, Issue 5, May 2025.
Gene duplication and alternative splicing expand the proteome, enabling ancestral genes to shape cell type evolution without jeopardizing their ancestral role. But how, exactly? In this piece, we propose that expression and functional specialization are key, underappreciated fates for paralogous genes and alternative isoforms throughout animal ...

Novel galanin receptors in teleost fish: identification, expression and regulation by sex steroids [PDF]

open access: yes, 2014
In fish, the onset of puberty, the transition from juvenile to sexually reproductive adult animals, is triggered by the activation of pituitary gonadotrophin secretion and its timing is influenced by external and internal factors that include the growth/

Describing the musculature of mystacial pads in harbour seals (Phoca vitulina) using diceCT

open access: yesJournal of Anatomy, Volume 246, Issue 5, Page 696-708, May 2025.
Harbour seals have movable mystacial vibrissae suggesting intrinsic muscles that aid protraction, yet their mystacial musculature is understudied. Using diceCT, we reveal the 3D structure of mystacial muscles for the first time. While the intrinsic muscles were regularly distributed, they were surprisingly small, contrary to expectations.

Rapid bursts of gene duplication occurred independently in diverse mammals [PDF]

open access: yes, 2008
Background: The draft mouse (Mus musculus) genome sequence revealed an unexpected proliferation of gene duplicates encoding a family of secretoglobin proteins including the androgen-binding protein (ABP) α, β and γ subunits. Further investigation of 14
