Article Abstract
Purpose: The increasing prevalence of obesity in children and its associated risk with cardiovascular diseases demand more discovery of the novel biomarkers for developing new treatment options for this complex disease. This study aimed to investigate the association of serum MOTS-C (a peptide encoded in the mitochondrial genome) levels and vascular endothelial function in obese children.
Patients And Methods: A total of 225 obese children (aged 8.1 ± 2.6 years) and 218 healthy children (aged 7.9 ± 2.2 years) were enrolled. Related anthropometric assessment and biochemical evaluation were done in all subjects. Reactive hyperemia index (RHI), as assessed by the peripheral arterial tonometry, was used for evaluation of peripheral endothelial function. Enzyme-linked immunosorbent assay (ELISA) was used to measure the level of serum MOTS-C.
Results: Levels of serum MOTS-C and RHI were lower in the obese children compared with the healthy children ( < 0.01). The RHI level was independently associated with body mass index, high-density lipoprotein cholesterol, and MOTS-C in linear regression analysis. Further analysis showed a significant mediating effect of MOTS-C on the correlation between body mass index and RHI in children, with the ratio of mediating effect value of 9.12%.
Conclusion: These data identify that MOTS-C is a previously unknown regulator in the development process of obesity-induced vascular changes.

Retrospective study on the value of serum angiopoietin 2 and cystatin C levels in the early diagnosis of acute coronary syndrome.

Acute coronary syndrome (ACS) is a coronary emergency that arises from myocardial ischemia and thrombosis and can be triggered by the rupture of a subcutaneous unstable plaque within the coronary artery or coronary artery erosion. The current study aimed to calculate the predictive value of serum angiopoietin 2 (Ang-2) and cystatin C (Cys-C) levels in the early diagnosis of ACS. We retrospectively analyzed data from 180 patients diagnosed with ACS at our hospital between January 2023 and June 2024, with 120 healthy volunteers serving as the control group during the same period.

Recent research has identified the mitochondrial open reading frame of the 12S rRNA-c (MOTS-c) as a crucial mitochondrial peptide that significantly influences metabolic regulation, mimics the effects of exercise, and mitigates oxidative stress. This study aims to investigate the relationship between serum MOTS-c levels and obstructive sleep apnea (OSA) to enhance our understanding of the disease's pathophysiology. By elucidating this relationship, we hope to uncover new insights into the mechanisms underlying OSA and its associated metabolic complications.

Background & Aims: Although maternal obesity is an independent risk factor for metabolic dysfunction-associated steatotic liver disease (MASLD), the pathogenesis remains unclear. We aimed to evaluate the effect and mechanisms of multigenerational maternal Western diet (WD) on MASLD progression, and test drug candidates.
Methods: Female mice were fed WD from 8 weeks before breeding initiation with a normal chow (NC)-fed male, throughout pregnancy and lactation.

Background: Allergic asthma (AA), a severe chronic respiratory disease of chronic airway inflammation, is characterized by bronchial epithelial barrier dysfunction. The MOTS-c/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a protective role in various diseases by reducing inflammatory responses. This study aimed to evaluate the effects of MOTS-c on airway epithelial barrier function in AA.

Acute respiratory distress syndrome (ARDS) following cardiopulmonary bypass (CPB) is driven by oxidative stress during lung ischemia-reperfusion injury (LIRI). Mitochondrial-derived peptide MOTS-c has emerged as a regulator of mitochondrial-nuclear communication, yet its role in CPB-induced ARDS remains unclear. Here, we identify MOTS-c as a critical mediator of endothelial protection against LIRI through MYH9-dependent nuclear translocation and transcriptional activation of antioxidant genes.
