Isolation and Structural Determination of the First 8-epi-type Tetrodotoxin Analogs from the Newt, Cynops ensicauda popei, and Comparison of Tetrodotoxin Analogs Profiles of This Newt and the Puffer Fish, Fugu poecilonotus

open access: yesMarine Drugs, 2012
Identification of new tetrodotoxin (TTX) analogs from TTX-possessing animals might provide insight into its biosynthesis and metabolism. In this study, four new analogs, 8-epi-5,6,11-trideoxyTTX, 4,9-anhydro-8-epi-5,6,11-trideoxyTTX, 1-hydroxy-8-epi-5,6 ...

Newt cells secrete extracellular vesicles with therapeutic bioactivity in mammalian cardiomyocytes

open access: yesJournal of Extracellular Vesicles, 2018
Newts can regenerate amputated limbs and cardiac tissue, unlike mammals which lack broad regenerative capacity. Several signaling pathways involved in cell proliferation, differentiation and survival during newt tissue regeneration have been elucidated ...

Breeding site traits of European newts (Triturus macedonicus, Lissotriton vulgaris, and Mesotriton alpestris: Salamandridae) in the Montenegrin karst region [PDF]

open access: yesArchives of Biological Sciences, 2008
We recorded the occurrence of three European newt species - the smooth newt (Lissotriton vulgaris), the eastern alpine crested newt (Triturus macedonicus), and the alpine newt (Mesotriton alpestris) - in the Montenegrin karst, as well as their breeding ...

Evidence for paedomorphosis in Macedonian crested newt (Triturus macedonicus) from Montenegro [PDF]

open access: yesArchives of Biological Sciences, 2015
One of the most interesting heterochronic processes in the European newt (genus Triturus) is paedomorphosis, a phenomenon of attaining reproductive maturity while retaining larval features. However, paedomorphosis seems to be rare in the crested

Connectivity, land use, and fish presence influence smooth newt (Lissotriton vulgaris) occurrence and abundance in an urban landscape

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionUrban areas are challenging environments for wetland species with complex habitat requirements and life cycles. However, even semiaquatic species, representing such complex wetland groups, can be provided with adequate conditions through ...

Newt regeneration genes regulate Wingless signaling to restore patterning in Drosophila eye

open access: yesiScience, 2021
Summary: Newts utilize their unique genes to restore missing parts by strategic regulation of conserved signaling pathways. Lack of genetic tools poses challenges to determine the function of such genes.

Corresponding mitochondrial DNA and niche divergence for crested newt candidate species. [PDF]

open access: yesPLoS ONE, 2012
Genetic divergence of mitochondrial DNA does not necessarily correspond to reproductive isolation. However, if mitochondrial DNA lineages occupy separate segments of environmental space, this supports the notion of their evolutionary independence.

Confirmation of Tylototriton ziegleri Nishikawa, Matsui & Nguyen, 2013 in China, with discussion on the relationship between T. verrucosus Anderson, 1871 and T. panwaensis Grismer, Wood, Quah, Thura, Espinoza & Murdoch, 2019 (Caudata, Salamandridae) [PDF]

open access: yesBiodiversity Data Journal, 2022
The distribution of the Ziegler’s Crocodile Newt Tylototriton ziegleri Nishikawa, Matsui & Nguyen, 2013 in China has been controversial. This species was originally recorded uncertainly from Guangxi Autonomous Region, China.

Salamander Insights Into Ageing and Rejuvenation

open access: yesFrontiers in Cell and Developmental Biology, 2021
Exhibiting extreme regenerative abilities which extend to complex organs and entire limbs, salamanders have long served as research models for understanding the basis of vertebrate regeneration.

Genetic and morphological data demonstrate hybridization and backcrossing in a pair of salamanders at the far end of the speciation continuum

open access: yesEvolutionary Applications, 2021
Deeply diverged yet hybridizing species provide a system to investigate the final stages of the speciation process. We study a hybridizing pair of salamander species—the morphologically and genetically drastically different newts Triturus cristatus and T.
