Effects of all-trans retinoic acid and oxygen concentration on the proliferation and differentiation of subcutaneous adipocytes in yak

Frontiers in Veterinary Science
In this study, we investigated the mechanism by which all-trans retinoic acid (ATRA) regulates the hypoxic adaptation of yak subcutaneous adipocytes through a dose-dependent regulation.

Comparisons Between Large‐Scale Genomic Variants and SNPs in Driving Population Divergence and Local Adaptation

Integrative Zoology, EarlyView.
Candidate genes identified from SNPs, indels, and SVs exhibited limited shared genes, suggesting that diverse variant types capture complementary aspects of the adaptive landscape. Our results underscore the importance of incorporating multiple types of genomic variation to achieve a more comprehensive understanding of evolutionary processes.

Genomic Diversity of the Endangered Guinan Toad‐Headed Lizard and Its Conservation Implications

Integrative Zoology, EarlyView.
We produced HiFi long reads and assembled a high‐quality genome for the Guinan toad‐headed lizard—Phrynocephalus guinanensis—and present a comprehensive conservation genomics assessment. Our findings clearly show population structure, a reduced genetic diversity pattern, and a strong bottleneck in demographic history, reaffirming the endangered status ...

Inhibin βB Mediates Oligotrophic Adaptation via Regulating Muscle Satellite Cell Proliferation and Differentiation in Schizopygopsis younghusbandi

Integrative Zoology, EarlyView.
① Nutrient deficiency upregulates inhibin βB, activating SMAD signaling to promote p21. Increased p21 inhibits mcm2/mcm4/mcm5 and cyclin E2, inducing G1‐phase arrest, slowing growth, and reducing energy consumption. ② Inhibin βB also upregulates pdgf‐c, which induces α‐SMA, leading to muscle satellite cell fibrosis.

Conserving Rodent Pests in Transition Toward Endangered Status

Integrative Zoology, EarlyView.
Rodent control invariably takes place in the context of ecosystems heavily modified by agriculture. Together, they are potent drivers of rodent decline and endangerment. Nineteen percent of 2349 rodent species evaluated in the IUCN Red List of threatened species are of some conservation concern.

Seasonal and Regional Dietary Heterogeneity Is Associated With Gut Microbiota Differentiation in Przewalski's Gazelle (Procapra przewalskii)

Integrative Zoology, EarlyView.
Seasonal and regional dietary variation in Przewalski's gazelle was linked to coordinated changes in gut microbiota, functional pathways, and fecal metabolites. Winter diets featured Poaceae, Cyperaceae, and Iridaceae, whereas summer diets shifted toward forb families.

Areas of high risk for mammalian biodiversity and nature's contributions to people under global warming

Conservation Science and Practice, EarlyView.
Climate change has reached unprecedented levels, causing frequent extreme events like droughts and fires. These changes are driving a sharp rise in extinction risk for mammals and threatening key Nature's Contributions to People (NCP) such as clean water, air quality, and climate regulation.

T2T genome assembly and CRISPR/Cas9 editing of Medicago lupulina

Journal of Integrative Plant Biology, EarlyView.
A complete, gap‐free genome of Medicago lupulina, a tough, high‐protein forage legume, and a gene‐editing tool for this species, which was used to alter its leaf shape, provide key resources for improving alfalfa and breeding better forage crops for high‐altitude environments.
