Evolutionary history of the Nesophontidae, the last unplaced Recent mammal family [PDF]

open access: yes, 2016
The mammalian evolutionary tree has lost several major clades through recent human-caused extinctions. This process of historical biodiversity loss has particularly affected tropical island regions such as the Caribbean, an area of great evolutionary ...

Establishment of an immortalized intestinal epithelial cell line from tree shrews by lentivirus-mediated hTERT gene transduction

open access: yesCytotechnology (Dordrecht), 2019
The intestinal epithelium has an average lifespan of 4–5 days. Normally, primary intestinal epithelial cells can be cultured for about 15 days in vitro.

Chinese Pangolin Changes Local Vertebrate Assemblages and Contributes to Their Interspecific Interactions by Burrowing and Revisitation

open access: yesIntegrative Zoology, EarlyView.
In this study, we systematically analyzed the utilization patterns of Chinese pangolin burrows by sympatric species in Guangdong Province, China, including differences in species composition using burrow mounds and burrow tunnels. We found that repeated visits to burrows by Chinese pangolin promoted the use of burrows by sympatric species, suggesting ...

Decoding thymic development: a single-cell atlas of tree shrew immunity

open access: yesFrontiers in Immunology
The tree shrew is a potential mammalian model for preclinical studies, but its immune system is not well understood. In this study, we utilized single-cell RNA sequencing (scRNA-seq) to construct a comprehensive cell atlas of the postnatal thymus ...

Optimizing procedures for ocular radiation injury studies in the tree shrew [PDF]

open access: yesExploration of Targeted Anti-tumor Therapy
Radiation exposure to the eye during cancer treatment can lead to ocular radiation injury (ORI), a devastating condition that can have a profound and permanent impact on vision-related quality of life. Rodent models do not have adequate ocular anatomy to

Introduced mona monkey Cercopithecus mona is a key predator of bird nests in the endemic‐rich Príncipe Island

open access: yesConservation Science and Practice, EarlyView.
Abstract Bird communities in oceanic islands tend to evolve under reduced predation, making them extremely susceptible to introduced predators. Príncipe Island (São Tomé and Príncipe, Central Africa) harbors 11 endemic bird species and eight introduced mammal species.

Historical shifts, geographic biases, and biological constraints shape mammal species discovery

open access: yesJournal of Systematics and Evolution, EarlyView.
Taxonomic descriptions of mammals have become more robust from 1990 to 2025, with increased specimen sampling, broader comparisons, and more integrative methods. However, disparities remain: tropical and small‐bodied species are less comprehensively described, reflecting ongoing geographic and biological biases.

Anatomy and nomenclature of tree shrew lymphoid tissues

open access: yesExperimental Animals, 2022
The immune response plays a key role in the disease development of the organism, while immune function serves as an important indicator for animal models evaluation. The tree shrew (Tupaia belangeri chinensis), as a new laboratory animal with a close genetic relationship with primates, has been used to construct various disease models.

The neuroprotective effect and RNA‐sequence analysis of postconditioning on the ischemic stroke with diabetes mellitus tree shrew model

open access: yesBrain and Behavior, 2021
Introduction Patients with comorbidity of ischemic stroke (IS) and diabetes mellitus (DM) show poor neurological functional recovery, and ischemic postconditioning (IPOC) should be considered a powerful neuroprotective method for IS.

Geometry and dimensionality reduction of feature spaces in primary visual cortex [PDF]

open access: yes, 2015
Some geometric properties of the wavelet analysis performed by visual neurons are discussed and compared with experimental data. In particular, several relationships between the cortical morphologies and the parametric dependencies of extracted features ...
