Muscle-homing peptides modified biomimetic curcumin nanoparticles ameliorate skeletal muscle dysfunction in aging mice

Redox Biology
With increasing age, skeletal muscle gradually loses mass and strength, and the risk of falls and fractures escalates among elderly individuals. Inflammation is closely related to age-related muscle atrophy and is the potential target for treating ...

Lactation is Associated with Accelerated Postpartum Pelvic Floor Muscle Recovery in a Pregnant Simulated Birth Injury Model

Advanced Science, EarlyView.
ABSTRACT Healthy pelvic floor muscles (PFMs) are essential for proper pelvic floor function. The biggest risk factor for PFM dysfunction is injury sustained during vaginal childbirth, yet the factors that facilitate or impair PFM recovery from birth injury remain unknown.

A Piezo1/KLF15/IL-6 axis mediates immobilization-induced muscle atrophy

The Journal of Clinical Investigation, 2022
Although immobility is a common cause of muscle atrophy, the mechanism underlying this causality is unclear. We here show that Krüppel-like factor 15 (KLF15) and IL-6 are upregulated in skeletal muscle of limb-immobilized mice and that mice with KLF15 ...

Mechanosensitive Piezo1/Osteocalcin/Irisin Axis Protects Against Disuse‐Induced Muscle Atrophy

Advanced Science, EarlyView.
Mechanical unloading suppresses bone Piezo1 expression, which reduces circulating undercarboxylated osteocalcin (unOCN). unOCN reduction subsequently exacerbates IMM‐induced Fndc5/Irisin decrease and drives severe muscle atrophy. Bone Piezo1 activation or exogenous osteocalcin/Irisin ameliorate muscle atrophy, while muscle‐specific Gprc6a or Fndc5 ...

A Skull Bone Marrow‐to‐Brain Axis Links Osteoblastic Activity to Myeloid Cell Trafficking, Cerebral Blood Flow, and Cognition in Alzheimer's Progression

Advanced Science, EarlyView.
This study reveals that Alzheimer's disease–linked APP expression in bone‐forming cells drives skull bone marrow remodeling and alters its vascular connections to the brain. These changes disrupt immune cell trafficking, cerebral blood flow, and cognition. Targeting bone marrow macrophages restores brain function, highlighting a previously unrecognized

FGFR1 inhibits skeletal muscle atrophy associated with hindlimb suspension

BMC Musculoskeletal Disorders, 2007
Background Skeletal muscle atrophy can occur under many different conditions, including prolonged disuse or immobilization, cachexia, cushingoid conditions, secondary to surgery, or with advanced age. The mechanisms by which unloading of muscle is sensed

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Long Non-Coding RNA Myoparr Regulates GDF5 Expression in Denervated Mouse Skeletal Muscle

Non-Coding RNA, 2019
Skeletal muscle is a highly plastic tissue and decreased skeletal muscle mass (muscle atrophy) results in deteriorated motor function and perturbed body homeostasis.

The Effect of Resistance Training and Ursolic Acid on the PI3K‐AKT‐mTOR Pathway in Aged Diabetic Rats: A Comparative Study

AGING MEDICINE, EarlyView.
Resistance training combined with ursolic acid supplementation restores anabolic signaling (PI3K/mTORC1) suppressed by diabetes, helping preserve muscle mass. This strategy may offer a potential therapeutic approach to combat muscle atrophy and support healthy aging in diabetic conditions.
