Loss of LCN2 Function Ameliorates Glucocorticoid‐Induced Muscle Atrophy via Remodeling the Extracellular Matrix

open access: yesAdvanced Science, EarlyView.
Glucocorticoids transcriptionally activate LCN2 expression via GR nuclear translocation. Secreted LCN2 binds MMP9 to degrade skeletal muscle ECM collagen, blocks integrin‐mediated mechanotransduction, bidirectionally disrupts muscle protein homeostasis, and reveals a novel target for steroid‐induced muscle atrophy.

Regeneration competent satellite cell niches in rat engineered skeletal muscle

open access: yesFASEB BioAdvances, 2019
Satellite cells reside in defined niches and are activated upon skeletal muscle injury to facilitate regeneration. Mechanistic studies of skeletal muscle regeneration are hampered by the inability to faithfully simulate satellite cell biology in vitro ...

Electronic Chip‐Mimetic Medical Implants for Controllable Sonothermal Treatments

open access: yesAdvanced Science, EarlyView.
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Satellite cells and myonuclei in young and elderly women and men

open access: yes, 2004
The overall aim of this study was to assess the effects of aging on the satellite cell population. Muscle biopsies were taken from the tibialis anterior muscle of healthy, moderately active young (age range, 20-32 years; n = 31) and elderly (age range ...

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide

open access: yesAdvanced Science, EarlyView.
This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

Elucidating the Role of BRCA1 in Skeletal Muscle Myogenesis and Function

open access: yes, 2023
The breast cancer 1 early onset gene (BRCA1) is a tumor suppressor gene susceptible to mutations associated with cancer development. We have identified that the BRCA1 gene is expressed in skeletal muscle and plays a critical role in regulating muscle ...

Intrasplenic Thymus Organogenesis from Injectable Tissue Fragments Restores Functional T‐Cell Immunity

open access: yesAdvanced Science, EarlyView.
Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

Research progress on the effect of muscle satellite cells on anal sphincter repair in neurogenic fecal incontinence

open access: yes结直肠肛门外科
Neurogenic fecal incontinence refers to the dysfunction of anal sphincter contraction caused by degenerative atrophy of the anal sphincter secondary to pudendal nerve injury, manifested as involuntary leakage of feces from the anus.

Targeting the NR1D1–IGF2BP2–V‐ATPase Axis With Hybrid Nanovesicles Restores Macrophage Rhythms to Reverse Sepsis‐Induced Immunosuppression

open access: yesAdvanced Science, EarlyView.
Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense.
