Molecular evolution of the neurohypophysial hormone precursors in mammals: comparative genomics reveals novel mammalian oxytocin and vasopressin analogues [PDF]

, 2012
Among vertebrates the neurohypophysial hormones show considerable variation. However, in eutherian mammals they have been considered rather conserved, with arginine vasopressin (AVP) and oxytocin (OT) in all species except pig and some relatives, where ...

Disparity of turbinal bones in placental mammals

The Anatomical Record, Volume 309, Issue 4, Page 749-777, April 2026.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Adaptive Genetic Variation in Black‐and‐White Snub‐Nosed Monkeys (Rhinopithecus bieti): Low Diversity and the Role of Balancing Selection

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We investigated the adaptive genetic diversity within a population of Rhinopithecus bieti using amplicon sequencing. From 47 individuals, we identified 16 MHC class I sequences, revealing a low level of adaptive genetic variation. Although evidence for balancing selection, including positive selection and trans‐species polymorphism, was observed, these

Hominids adapted to metabolize ethanol long before human-directed fermentation [PDF]

, 2014
Paleogenetics is an emerging field that resurrects ancestral proteins from now-extinct organisms to test, in the laboratory, models of protein function based on natural history and Darwinian evolution. Here, we resurrect digestive alcohol dehydrogenases (

Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, Volume 12, Issue 46, December 11, 2025.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.

Property of hepatitis B virus replication in Tupaia belangeri hepatocytes

Biochemical and Biophysical Research Communications, 2016
The northern treeshrew (Tupaia belangeri) has been reported to be an effective candidate for animal infection model with hepatitis B virus (HBV). The objective of our study was to analyze the growth characteristics of HBV in tupaia hepatocytes and the host response to HBV infection.

Descriptive Histology and Anatomy of the Nasal Cavity and Its Associated Sensory Organs in the European Hedgehog (Erinaceus europaeus) Based on Four Standardised Transverse Sections

Anatomia, Histologia, Embryologia, Volume 54, Issue 6, November 2025.
ABSTRACT The nasal cavity of European hedgehogs (Erinaceus europaeus) harbours a well‐developed olfactory system, essential for food provision and communication. Additionally, it acts as a first line of defence by preventing pathogens and irritants from reaching the lungs, thereby playing an important physiological role.

Basal physiological parameters in domesticated tree shrews ( Tupaia belangeri chinensis ) [PDF]

Zoological Research, 2013
Establishing non-human primate models of human diseases is an efficient way to narrow the large gap between basic studies and translational medicine. Multifold advantages such as simplicity of breeding, low cost of feeding and facility of operating make the tree shrew an ideal non-human primate model proxy.

Variation in Small Mammal Species Composition and the Occurrence of Parasitic Mites in Two Landscapes in a Scrub Typhus Endemic Region of Western Yunnan Province, China

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Yunnan Province, the most serious scrub typhus endemic areas in China, provides abundant ecological resources that sustain parasite and host populations. The distribution of vector‐borne diseases is driven by interactions between hosts, vectors and the environment, revealing critical ecological dynamics.

Hepatitis C virus infection of primary tupaia hepatocytes leads to selection of quasispecies variants, induction of interferon-stimulated genes and NF-kappaB nuclear translocation [PDF]

, 2005
Systems for in vitro culture of Hepatitis C virus (HCV) are essential tools to analyse virus-cell interactions and to investigate relevant pathophysiological aspects of HCV infection.
