Summary: Perturbations are common in metabolism, and sensitivity analysis is a key tool to understand and control their impact on metabolic networks. This paper adopts a structural approach based on network stoichiometry to investigate the network's response to perturbations in reaction rates and metabolite concentrations at equilibrium. The study focuses on the sign of the responses and identifies the subnetworks that play a major role in sign description.

Summary: This study evaluated the effect of stigmasterol (STIG) and stigmasterol-dexamethasone combination (STIG+DEX) in steroid-resistant asthma. The findings showed that STIG alone had no effect on inflammatory features, but caused some changes in the molecular events related to steroid-resistant asthma. However, the combination of STIG+DEX significantly modulated inflammatory features and protected against lung tissue destruction.

Summary: Adrenal insufficiency (AI) is associated with higher mortality and morbidity compared with the general population. Conventional replacement steroid therapy leads to increased metabolic comorbidities, while dual-release hydrocortisone offers a decreased risk and mimics the physiological profile of cortisol. The reduced daily steroid exposure of dual-release hydrocortisone spares the clock genes involved in metabolic pathways, maintaining the normal physiological circadian rhythm of endogenous cortisol. This narrative review focuses on the metabolic comorbidities of AI due to steroid replacement therapy, evaluating the effects of conventional and novel drugs with attention to chronopharmacology.

Summary: Obesity and metabolic syndrome are global concerns. Zebrafish have been used to study the biology and etiology of obesity. This study found that long-term obesity in zebrafish leads to metabolic abnormalities similar to mammals, but without glucose dysregulation. Early caloric restriction in zebrafish did not exacerbate metabolic syndrome, while later exposure to the obesogenic environment did not completely reverse the effects of caloric restriction.

Summary: The study found that COPD patients had higher CAC, lower muscle oxidative capacity, and lower self-reported PA levels compared to controls. Multivariate analysis revealed a significant negative association between CAC and the difficulty score of PA. These findings suggest that COPD patients with elevated CAC may experience greater difficulty in performing daily activities.

Summary: Malignant pleural mesothelioma (MPM) is a lethal malignancy caused by asbestos exposure. In this study, we found that the hyperactive MAPK pathway is a molecular driver of MPM, and blocking this pathway induces cell apoptosis. Additionally, the MAPK pathway cooperates with PARP1 to regulate ROS levels, and combining MEK inhibitors with PARP inhibitors enhances cell apoptosis.

Summary: The study suggests that prenatal testosterone excess may lead to insulin resistance, mainly due to mitochondrial and endoplasmic reticulum dysfunction in muscle. Additionally, fibrosis and premature senescence may occur in the liver, while changes in mitochondrial function and ER stress in different adipose tissues are depot-specific.

Summary: The study found that individuals with early chronotypes who have metabolic syndrome tend to utilize more fat during rest and exercise compared to those with late chronotypes. This difference in fuel selection is associated with higher physical activity levels throughout the day for early chronotypes. Additionally, the findings suggest that greater fat utilization in early chronotypes is related to non-oxidative glucose disposal and may influence their risk for type 2 diabetes.

Summary: This article summarizes the significance of the interplay between hydrogen sulfide (H2S) and iron in cellular fate and wellness. The abnormal metabolisms of both iron and H2S are associated with various diseases. Future studies should evaluate the physiological and pathophysiological importance of H2S and iron together, and expand research to other fields where the interaction between H2S and iron has not been well studied.

Summary: Hydrogen sulfide (H2S) promotes glycolysis-mediated energy production in mitochondria-free mouse red blood cells by regulating endogenous H2S production through the enzyme MST. Both exogenous H2S and endogenous H2S derived from MST stimulate ATP production through glycolysis. The effects of H2S on ATP levels and cell viability are concentration-dependent, with low concentrations increasing ATP levels but decreasing cell viability, and high concentrations lowering ATP levels but prolonging cell viability. H2S may offer a cytoprotective effect in mammalian red blood cells to maintain oxygen-independent energy production.

Summary: This study investigated the effects of sodium thiosulfate (Na2S2O3) administration during resuscitation from trauma-and-hemorrhage in mice under conditions of whole body cystathionine gamma-lyase (CSE) deficit. The results showed that Na2S2O3 exerted beneficial effects in terms of organ protection and anti-inflammatory properties, improving lung function, reducing norepinephrine requirements, increasing urine output, and regulating inflammatory response and oxidative stress in the kidney tissue. These findings suggest that Na2S2O3 could be a potential therapeutic option in the context of impaired CSE activity and/or reduced endogenous H2S availability.

Summary: This study discovered that polycyclic polyprenylated acylphloroglucinols from the fruits of Garcinia cambogia have lipid-lowering effects and can induce browning of adipocytes. Among them, guttiferone J (GOJ) is the most potent inducer of browning, which activates the deacetylase SIRT3 to enhance mitochondrial biogenesis and thermogenesis. In high-fat diet-induced obese mice, GOJ protected against obesity and related disorders by promoting browning of adipose tissue.

Summary: Hypertension is a complex health challenge with multiple causes, while hydrogen sulfide (H2S) serves as a multifunctional gasotransmitter. Animal studies conducted 15 years ago have established the critical role of endogenous H2S deficiency in hypertension development, leading to further investigations into its cardiovascular effects and underlying molecular and cellular mechanisms. We are also beginning to understand the involvement of altered H2S metabolism in human hypertension. This article aims to provide a comprehensive understanding of H2S's roles in hypertension development in both animals and humans, and review H2S-based antihypertension therapeutic strategies.

Summary: Reactive sulfur species, such as cysteine hydropersulfide and glutathione persulfide, are produced abundantly in both prokaryotes and eukaryotes, including mammals. Cysteinyl-tRNA synthetase (CARS) has been identified as a new cysteine persulfide synthase (CPERS) responsible for the production of most reactive persulfides. However, the contribution of other enzymes, such as 3-mercaptopyruvate sulfurtransferase (3-MST), cystathionine beta-synthase (CBS), and cystathionine gamma-lyase (CSE), to reactive persulfide production is still debated. In this study, the authors used sulfur metabolome analysis to demonstrate that 3-MST, CBS, and CSE are not major sources of reactive persulfides in mammals, and CARS/CPERS is the principal enzyme involved.

Summary: This study demonstrates the improved dielectric and capacitive performance of a polypropylene composite by grafting a molecular semiconductor onto polypropylene chains. The grafted molecular semiconductor introduces deep traps to inhibit the migration of high-energy charge carriers and enhances the regulation effect by positively influencing the microstructure of the polymer. The composite exhibits reduced leakage current, dielectric loss, electric field distortion, and increased breakdown strength at high temperatures.
