T2T Genomes Unveil Centromere Architecture and Adaptive Divergence in Large Yellow Croaker (Larimichthys crocea)

open access: yesAdvanced Science, EarlyView.
This study presents telomere‐to‐telomere genome assemblies for two populations of Larimichthys crocea. We identified centromere‐specific tandem repeats invaded by LTR/ERV1 retrotransposons, unique 5S rRNA enrichment patterns, and population‐specific structural variants. Comparative genomic analyses further reveal distinct adaptive mechanisms in the MYD

Diversity and community composition of methanogenic archaea in the rumen of Scottish upland sheep assessed by different methods.

open access: yesPLoS ONE, 2014
Ruminal archaeomes of two mature sheep grazing in the Scottish uplands were analysed by different sequencing and analysis methods in order to compare the apparent archaeal communities. All methods revealed that the majority of methanogens belonged to the

Multi‐Habitat Landscape Promotes Microbial Diversity: Insights from the Traditional Agricultural Heritage and the Global Trend

open access: yesAdvanced Science, EarlyView.
The 2500‐year‐old Mulberry‐dyke and Fish‐pond agricultural heritage system reveals how interconnected habitats foster microbial diversity. Multi‐habitat landscapes enhance microbial diversity through cross‐habitat dispersal and adaptive trait convergence. Globally, regions with diverse habitats support a greater diversity of soil microbiomes.

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

open access: yesAdvanced Science, EarlyView.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

Identification of Bacterial Fish Pathogens in Brazil by Direct Colony PCR and 16S rRNA Gene Sequencing

open access: yes, 2015
Intensive fish farming systems in Brazil have increased the disease incidence, mainly of bacterial origin, due to higher stocking density, high organic matter levels and poor quality of the aquatic environment that causes high mortality rates during ...

Mechanical Environment Afforded by Engineered Hydrogel Critically Regulates Survival of Neural Stem Cells Transplanted in the Injured Spinal Cord via Piezo1‐Mediated Mechanotransduction

open access: yesAdvanced Science, EarlyView.
Neural stem cell transplantation shows promise for spinal cord repair, but poor graft survival limits therapeutic efficacy. This study demonstrates that increasing hydrogel stiffness from 10% to 16% concentration significantly enhances transplanted neural stem cell survival through Piezo1‐mediated mechanotransduction, revealing mechanical properties as

Tumor Intrinsic METTL5 Modulates ATF4 Translation to Prevent T Cell‐Induced Ferroptosis in Ovarian Cancer

open access: yesAdvanced Science, EarlyView.
An integrative analysis combining in vitro genome‐wide immune screens, in vivo ICB screens, and clinical data mining identifies METTL5 as a key tumor‐intrinsic immune factor. Mechanistic studies further reveal the importance of the METTL5‐ATF4‐SLC7A11/SLC3A2‐ferroptosis axis in modulating antitumor immune responses. These findings highlight METTL5 as a

Phospholipid Remodeling and Tri‐Layer Membrane Reconstruction Mediate Cognitive Effects of Humanized Milk Fat Globules in Neonatal Rats

open access: yesAdvanced Science, EarlyView.
Humanized milk fat globules (MFG) mimic the native composition and structure of human milk, achieved through remodeling of milk fat globule membrane phospholipid composition and reconstruction of the tri‐layer membrane structure. These humanized MFG exhibit improved structural stability and digestibility, and enhance neurodevelopment in formula‐fed rat
