Trabecular Bone Deficit and Enhanced Anabolic Response to Re-Ambulation after Disuse in Perlecan-Deficient Skeleton

open access: yesBiomolecules, 2020
Perlecan/Hspg2, a large monomeric heparan sulfate proteoglycan, is found in the basement membrane and extracellular matrix, where it acts as a matrix scaffold, growth factor depot, and tissue barrier.

The impact of hindlimb disuse on sepsis‐induced myopathy in mice

open access: yesPhysiological Reports, 2021
Sepsis induces a myopathy characterized by loss of muscle mass and weakness. Septic patients undergo prolonged periods of limb muscle disuse due to bed rest. The contribution of limb muscle disuse to the myopathy phenotype remains poorly described.

Decoding Human Placental Cellular and Molecular Responses to Obesity and Fetal Growth

open access: yesAdvanced Science, EarlyView.
Women with obesity often deliver large‐for‐gestational‐age (LGA) infants. Single‐nucleus RNA sequencing of term placenta reveals that hypoxia and TNF‐α signaling in syncytiotrophoblasts are featured in maternal obesity, but inflammatory signatures in Hofbauer cells and response to lipid or carbohydrate metabolism in fibroblasts are specific to LGA.

Decreased expression of H19/miR-675 ameliorates muscle atrophy by regulating the IGF1R/Akt/FoxO signaling pathway

open access: yesMolecular Medicine, 2023
Background Long non-coding RNA (lncRNA) H19 is one of the most highly expressed and conserved transcripts in mammalian development, and its functions have been fully discussed in many contexts including tumorigenesis and skeletal muscle development ...

Skeletal Muscle HSF1 Alleviates Age‐Associated Sarcopenia and Mitochondrial Function Decline via SIRT3‐PGC1α Axis

open access: yesAdvanced Science, EarlyView.
Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...

Bone mineral density of rat femurs after hindlimb unloading and different physical rehabilitation programs

open access: yesRevista Ceres, 2011
Bone weakening can occur due to the absence of load on the skeleton or even short periods of decreased physical activity. Therefore, musculoskeletal diseases that involve temporary immobilization by casts, inactivity or tension increases the risk of ...

Microenvironment Self‐Adaptive Nanoarmor to Address Adhesion‐ and Colonization‐Related Obstacles in Impaired Intestine Promote Bacteriotherapy Against Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
A microenvironment self‐adaptive nanoarmor is developed to effectively address the adhesion‐ and colonization‐related challenges posed by multiple physiological and pathological characteristics in the intestine. L. plantarum@MPN@CS showed significant therapeutic potential in treating Parkinson's disease (PD), a model for extraintestinal disorders, as ...

Comparative plasma proteomics in muscle atrophy during cancer‐cachexia and disuse: The search for atrokines

open access: yesPhysiological Reports, 2020
Skeletal muscle atrophy is common across a variety of pathologies. Underlying mechanisms of atrophy differ between pathologies, and in many conditions, circulating factors are tied to muscle atrophy.

Nanogel Integrated Zwitterionic Injectable Hydrogel with Sequential Drug‐Releasing Capability for the Programmable Repair of Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
A novel drug‐loaded D/P‐g‐PSB nanogel‐incorporated hydrogel by the electrostatic attraction‐driven self‐assembling process. Sequential drug releasing property (melatonin is released first by physical diffusion, and then ibuprofen is released as the charge shielding effect and hydrogel degradation). This ion‐sensitive hydrogel platform with sequentially

Nanoparticle Adjuvant Design Enhances Germinal Center Responses Targeting Conserved Subdominant Epitopes for Pan‐Coronavirus Vaccine Development

open access: yesAdvanced Science, EarlyView.
Current SARS‐CoV‐2 vaccines generate short‐lived, strain‐specific immunity. A polymeric TLR7 agonist nanoparticle (TLR7‐NP) adjuvant enhances lymph node targeting and promotes early and sustained germinal center responses toward conserved S2 epitopes of the spike protein.
