Impaired hydrogen sulfide biosynthesis underlies eccentric contraction-induced force loss in dystrophin-deficient skeletal muscle.
J Clin Invest
January 2025
Department of Biochemistry, Molecular Biology & Biophysics, University of Minnesota, Minneapolis, United States of America.
Eccentric contraction- (ECC) induced force loss is a hallmark of murine dystrophin-deficient (mdx) skeletal muscle that is used to assess efficacy of potential therapies for Duchenne muscular dystrophy. While virtually all key proteins involved in muscle contraction have been implicated in ECC force loss, a unifying mechanism that orchestrates force loss across such diverse molecular targets has not been identified. We showed that correcting defective hydrogen sulfide (H2S) signaling in mdx muscle prevented ECC force loss.

Myocardial infarction (MI) is a coronary artery-related disease that seriously threatens human life and is the leading cause of sudden death worldwide, where a lack of nutrients and oxygen leads to an inflammatory response and death of cardiomyocytes. Ferroptosis is a form of non-apoptotic cell death associated with metabolic dysfunction, resulting in abnormal breakdown of glutamine and iron-dependent accumulation of reactive oxygen species (ROS) during metabolism. However, the molecular mechanism of ferroptosis in the pathogenesis of MI and the function of Klotho and KRAS on ferroptosis during MI remain unclear.

January 2025
Department of Pharmacy, The Second Xiangya Hospital, Central South University, Changsha, 410011, Hunan, China.
Purpose: Doxorubicin (Dox) is a classic anthracycline chemotherapy drug with cause cumulative and dose-dependent cardiotoxicity. This study aimed to investigate the potential role and molecular mechanism of phenylacetylglutamine (PAGln), a novel gut microbiota metabolite, in Dox-induced cardiotoxicity (DIC).
Methods: DIC models were established in vivo and in vitro, and a series of experiments were performed to verify the cardioprotective effect of PAGln.
Phytochemicals in Obesity Management: Mechanisms and Clinical Perspectives.
Curr Nutr Rep
January 2025
Research and Development cell, Department of Intellectual property Rights, Lovely Professional University, Jalandhar- Delhi Grand Trunk Rd., Phagwara, Punjab, 144411, India.
Purpose Of Review: This review explores the mechanistic pathways and clinical implications of phytochemicals in obesity management, addressing the global health crisis of obesity and the pressing need for effective, natural strategies to combat this epidemic.
Recent Findings: Phytochemicals demonstrate significant potential in obesity control through various molecular mechanisms. These include the modulation of adipogenesis, regulation of lipid metabolism, enhancement of energy expenditure, and suppression of appetite.
A comprehensive analysis to reveal the underlying molecular mechanisms of natural killer cell in thyroid carcinoma based on single-cell RNA sequencing data.
Discov Oncol
January 2025
The Department of Experimental Medicine, Meishan City People's Hospital, No. 288, South Fourth Section, Dongpo Avenue, Meishan, 620000, Sichuan, China.
Background: Thyroid carcinoma (THCA) is the most common cancer of the endocrine system. Natural killer (NK) cell play an important role in tumor immune surveillance. The aim of this study was to explore the possible molecular mechanisms involved in NK cell in THCA to help the management and treatment of the disease.
