Hypothalamic mTOR signaling mediates the orexigenic action of ghrelin.

open access: yesPLoS ONE, 2012
Current evidence suggests that ghrelin, a stomach derived peptide, exerts its orexigenic action through specific modulation of Sirtuin1 (SIRT1)/p53 and AMP-activated protein kinase (AMPK) pathways, which ultimately increase the expression of agouti ...

HDAC9 Contributes to Serous Ovarian Cancer Progression through Regulating Epithelial–Mesenchymal Transition

open access: yesBiomedicines, 2022
Epithelial ovarian cancer has the highest mortality rate of all gynecological malignant tumors. Metastasis is the main cause of poor prognosis in patients with ovarian cancer.

N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

open access: yesiNew Medicine, EarlyView.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

Resistance‐exercise‐induced stress intervenes in TGF‐β signaling by cooperatively downregulating nuclear αB‐crystallin and SMAD4 in human skeletal muscle fibers

open access: yesThe FEBS Journal, EarlyView.
Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

Inflammation and mechanical force‐induced bone remodeling

open access: yesPeriodontology 2000, EarlyView.
Abstract Periodontitis arises from imbalanced host–microbe interactions, leading to dysbiosis and destructive inflammation. The host's innate and adaptive immune responses produce pro‐inflammatory mediators that stimulate destructive events, which cause loss of alveolar bone and connective tissue attachment.

Mechanical load regulates bone growth via periosteal Osteocrin

open access: yesCell Reports, 2021
Summary: Mechanical stimuli including loading after birth promote bone growth. However, little is known about how mechanical force triggers biochemical signals to regulate bone growth. Here, we identified a periosteal-osteoblast-derived secretory peptide,

Oxidative Stress in the Tumor Immune Microenvironment: Mechanisms and Therapeutic Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Oxidative stress is involved in several key processes in cancer, including redox regulation, DNA damage, post‐translational modifications, transcriptional regulation, epigenetic modifications, metabolic reprogramming, cell death, and immune modulation. These mechanisms collectively influence tumor progression, immune evasion, and therapeutic responses,
