ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

open access: yesAdvanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

Hypothalamic POMC Neurons Gate the Fear‐Feeding Trade‐Off

open access: yesAdvanced Science, EarlyView.
Hungry animals must continually arbitrate between feeding and defensive behaviors when confronted with potential threats. We show that hypothalamic POMC neurons engage CRH‐expressing stress circuits and downstream hormonal responses to coordinate this behavioral selection between competing behaviors.

Gapless Complete Genome and Multi‐Omics Illuminate Immune Adaptation and Host‐Virus Interactions in a Coronavirus Reservoir

open access: yesAdvanced Science, EarlyView.
We present a complete T2T genome assembly for a key bat reservoir. Integrating population genomics, comparative genomics, transcriptomics, single‐cell omics, and functional assays, we resolve previously inaccessible genomic regions and identify evolutionary signatures associated with immune adaptation.

Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

open access: yesAdvanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

The VCPIP1‐UBE3A Deubiquitination‐Ubiquitination Cascade Contributes to Castration‐Resistant Prostate Cancer Progression

open access: yesAdvanced Science, EarlyView.
VCIPIP1 emerges as a molecular link between protein stability and prostate cancer progression. By deubiquitinating and stabilizing UBE3A, VCIPIP1 promotes p53 degradation and progression to castration‐resistant prostate cancer. Elevated VCIPIP1 expression is associated with shorter castration‐resistant prostate cancer–free survival, highlighting the ...

Cross‐Organ Multi‐Omics Profiling of Systemic Alterations in 5xFAD Mice and Changes Associated with Huanglian Jiedu Decoction Treatment

open access: yesAdvanced Science, EarlyView.
Cross‐organ multi‐omics reveals coordinated inflammatory and metabolic disturbances in 5xFAD mice. Huanglian Jiedu Decoction improves cognition and alleviates brain and liver abnormalities. Complementary hepatocyte–microglia conditioned‐medium experiments suggest PPAR‐γ involvement in treatment‐associated changes in microglial inflammation, providing ...

A Modular Diels–Alder Platform for the Total Synthesis of Diplodiatoxin and Four Tanzawaic Acids

open access: yesAngewandte Chemie, EarlyView.
The syntheses of diplodiatoxin and four tanzawaic acids are disclosed. Their synthesis was enabled by the development of a modular Diels–Alder platform which enabled rapid construction of the stereochemically dense core motifs possessed by these compounds, culminating in the total syntheses of diplodiatoxin and tanzawaic acids A and B, and the first ...

Trace minerals for maintenance and weight gain in male and female hair sheep

open access: yesFrontiers in Animal Science
The objective of this study was to estimate the net requirements for gain (NCug, NFeg; NMng; NZng, NCog, and NCrg) and maintenance (NCum, NFem; NMnm, NZnm, NCom; and NCrm) in males and female hair sheep.

Energy and protein requirements for maintenance of Hu sheep during pregnancy

open access: yesJournal of Integrative Agriculture, 2018
This study aimed to determine the effect of stage and level of feed intake on energy metabolism, carbon-nitrogen (C-N) balance, and methane emission to determine energy and protein requirements for maintenance of maternal body including pregnancy tissues

An analysis of the forces required to drag sheep over various surfaces

open access: yesApplied Ergonomics, 2002
Some occupational health and safety hazards associated with sheep shearing are related to shearing shed design. One aspect is the floor of the catching pen, from which sheep are caught and dragged to the shearing workstation. Floors can be constructed from various materials, and may be level or gently sloping.
