Adhesion of gecko lizards to vertical surfaces is influenced by digital proteins
Some lizards, especially numerous species of geckos, are able to stick, walk and run along vertical or inverted surfaces, defeating gravity (Fig. 1 A). The nature of the subtrates is very variable in both physical and chemical
Vitellogenesis: not only in the liver and not only in females
Vitellogenin (VTG) is an estrogen-dependent, females-specific yolk precursor protein naturally synthesized during the reproductive period in the liver of oviparous vertebrates. Released in blood, VTG is taken from the growing oocytes by micropinocytosis and used as nourishment
Tail regeneration in lizard is driven by key genes of the Wnt-pathway
The importance of lizards as models to analyze the process of organ regeneration is relevant since, differently from the classical amphibian models, these vertebrates are amniotes adapted to the terrestrial environment, therefore closer to mammals and humans.
Key genes for amniote organ regeneration detected in lizard transcriptomes shed new hope for limb regeneration in humans
While in water-adapted vertebrates (anamniotes: fish and amphibians) organ regeneration is relevant or outstanding, including in fins or limbs, in fully terrestrial vertebrates (amniotes: reptiles, birds and mammals) regeneration is absent or rare. Aside numerous anatomical and
How to measure maximum animal performance
Scientists are often interested in the performance capabilities of animals, measuring how fast they can run or how hard they can bite. This information helps scientists understand how the bodies of different animals work and how they
