BACKGROUND Liver injury is common in severe acute pancreatitis(SAP).Excessive autophagy often leads to an imbalance of homeostasis in hepatocytes,which induces lipid peroxidation and mitochondrial iron deposition and ultimately leads to ferroptosis.Our previous study found that milk fat globule epidermal growth factor 8(MFG-E8)alleviates acinar cell damage during SAP via binding toαvβ3/5 integrins.MFG-E8 also seems to mitigate pancreatic fibrosis via inhibiting chaperone-mediated autophagy.AIM To speculate whether MFG-E8 could also alleviate SAP induced liver injury by restoring the abnormal autophagy flux.METHODS SAP was induced in mice by 2 hly intraperitoneal injections of 4.0 g/kg L-arginine or 7 hly injections of 50μg/kg cerulein plus lipopolysaccharide.mfge8-knockout mice were used to study the effect of MFG-E8 deficiency on SAPinduced liver injury.Cilengitide,a specificαvβ3/5 integrin inhibitor,was used to investigate the possible mechanism of MFG-E8.RESULTS The results showed that MFG-E8 deficiency aggravated SAP-induced liver injury in mice,enhanced autophagy flux in hepatocyte,and worsened the degree of ferroptosis.Exogenous MFG-E8 reduced SAP-induced liver injury in a dose-dependent manner.Mechanistically,MFG-E8 mitigated excessive autophagy and inhibited ferroptosis in liver cells.Cilengitide abolished MFG-E8’s beneficial effects in SAP-induced liver injury.CONCLUSION MFG-E8 acts as an endogenous protective mediator in SAP-induced liver injury.MFG-E8 alleviates the excessive autophagy and inhibits ferroptosis in hepatocytes by binding to integrinαVβ3/5. 展开更多

Milk fat globule epithelial growth factor VIII(MFG-E8) is a novel adhesion protein mainly produced by macrophages and dendritic cells; it is expressed in most of the human tissues and functions to prompt cancer progression and survival. MFG-E8 contains a signal sequence for secretion, two epidermal growth factor(EGF)-like domains at the NH2 terminus and two discoidin domains with blood-clotting factor V/factor Ⅷ(C1 and C2) at the COOH terminus. The second EGF domain contains an arginine-glycine-aspartic(RGD) integrin-binding motif that engages α_vβ_5 integrins to facilitate cell adhesion and induce integrinmediated signal transduction. Integrin α_vβ_3 associates with VEGF receptor 2, engagement of integrins can promote angiogenesis, which plays key roles in growth, proliferation, and survival of cancer cells. VEGF stimulates the expression of α_vβ_3 and α_vβ_5 integrins on angiogenic vasculature, thereby potentiating effects of VEGF receptor engagement. Mice expressing a mutant form of α_vβ_3 integrin are unable to undergo tyrosine phosphorylation, confirming the important role that this integrin plays in pathological angiogenesis and providing important mechanistic insights. The C-terminus discoidin-like domains promote binding to membrane phospholipids, functioning close to VEGF like angiogenesis. MFG-E8 is an opsonin for apoptotic cells, and it acts as a bridging protein between apoptotic cells and phagocytes. It also influences cell immunities by altering CD4^+ and/or CD8^+ cells. Antibody or small peptide works with MFG-E8 at different functional sites or interacts with EGF-like domains and/or discoidin-like domains may play an important role in anti-angiogenesis or immune restoration. Altering the structures and/or functions of MFG-E8 and/or its domains is promising for development of novel anti-cancer strategies. 展开更多

Objective: The use of animal models of aortic stenosis(AS) remains essential to further elucidate its pathophysiology and to evaluate new therapeutic strategies. The waved-2 mouse AS model has been proposed;data have indicated that while aortic regurgitation(AR) is effectively induced, development of AS is rare.We aimed to evaluate the effect of high-fat diet(HFD) and vitamin D_3 supplementation in this model.Methods: HFD and subcutaneous vitamin D_3 injections were initiated at the age of 6 weeks until the age of 6(n = 16, 6-month treatment group) and 9(n = 11, 9-month treatment group) months. Twelve waved-2 mice without supplementation were used as control. Echocardiography was performed at 3, 6 and 9 months. Blood serum analysis(calcium, 1,25(OH)_2D_3 and cholesterol), histology and immunohistochemistry(CD-31, CD-68 and osteopontin) were evaluated at the end of the experiment(6 or 9 months).Results: Total cholesterol and 1,25(OH)_2D_3 were significantly increased relative to the control group. HFD and vitamin D_3 supplementation did result in improvements to the model, since AS was only detected in 6(15.3%) mice(2 in the 3 groups) and AR was developed in the remaining animals. Echocardiographic parameters, fibrosis, thickness, inflammation and valvular calcification, were not significantly different between the 6-month treatment and control groups. Similar results were also observed in the 9-month treatment group.Conclusion: These results suggest that HFD and vitamin D_3 supplementation have no effect in the waved-2 mouse model. This model essentially mimics AR and rarely AS. Further studies are needed to find a reliable animal model of AS. 展开更多

Background: In the global burden of non-communicable diseases, the top slot among them all is occupied by various cardiovascular diseases (CVD), which also claim primacy in mortality rates. Generally speaking, the pathophysiological pathway frequently involves either (or a combination of) elevated serum cholesterol levels, predominantly attributed to dietary patterns characterized by extremely high levels of saturated and trans-fat consumption. Day-to-day nutritional epidemiology among university students suggests that they represent a crucial demographic for the study of preventive interventions. Objective: This in-depth study and investigation were specifically aimed to quantitatively assess and compare prevailing patterns of dietary fat consumption between female students enrolled in health sciences and non-health sciences programs at major universities in Riyadh, Saudi Arabia. Methodology: This cross-sectional study was comprised of 434 Saudi female university students (age range: 18 - 25 years), utilizing a validated Block Dietary Fat Screener accompanied by anthropometric measurements and comprehensive demographic data collection. The sampling methodology consisted of a snowball technique that was spread across three major academic institutions in Riyadh. Results: Statistical analysis revealed a significant association between academic specialization and patterns of dietary fat consumption (p = 0.012). Paradoxically, students of health science exhibited a higher prevalence of very high fat intake (41.9%) compared with their non-health sciences counterparts (27.6%). Surprisingly, anthropometric stratification revealed that it was the underweight students who demonstrated very high levels of fat consumption. A notable socioeconomic gradient was observed, with students from households earning 15,000 - 20,000 SR monthly showing the highest prevalence of very high-fat consumption (47.1%), although this association did not achieve statistical significance (p = 0.104). Conclusion: These findings challenge the conventional assumption that health sciences education correlates with superior dietary behaviors. The data suggests a critical need for enhanced education in nutrition, as well as intervention using various behavioral programs across all academic disciplines, particularly those addressing the disconnect between nutritional knowledge and dietary practices among students of health sciences. Future longitudinal studies are warranted in order to elucidate the temporal relationship between academic specialization and dietary behaviors. 展开更多

Obesity in childhood or adolescence has been recognized to be a risk factor for the onset of lifestyle-related diseases, not only in healthy children, but also in children with developmental disorders. Therefore, this study was conducted to examine the characteristics of obesity and thinness as assessed by the body fat percentage among children with developmental disorders during certain growth periods. It was also designed to investigate those factors associated with obesity and thinness based on a lifestyle and behavioral questionnaire. The subjects included 260 children from 5 to 18 years old with developmental disorders. The results of the study showed that a decrease in thinness and increase in obesity with ageing exhibited more noticeable trends among those children with mental retardation. The factors associated with obesity in children with developmental disorders were characterized by the dietary content, eating behaviors, and food preferences particular to such children, as well as low physical activity and a family history of obesity. The results of this study suggested the importance of continuous guidance along with family participation in order to improve obesity among children with developmental disorders, while focusing on the characteristics of certain growth periods. 展开更多

Body Mass Index (BMI) and Percentage Body Fat (%BF) values have been determined in cancer patients. In the study, 83 adult cancer patients were assessed of which 15 (18.1%) were males and 68 (81.9%) females. Body weight and height of individual patients were used in calculating their respective BMI values. The respective %BF values were determined taking into consideration of the age, gender and BMI. Maximum values of BMI (34.71 kg/m2) and %BF (46.37%) were obtained, for which they were females and the minimum values of BMI (12.08 kg/m2) and %BF (12.35%) respectively. The patient with the minimum %BF value was male and that of BMI was female. It was observed from the results that females have higher values of both BMI and %BF than their male counterparts. The study reveals higher rate of female cancer incidence than males. 展开更多

Background: Epicardial adipose tissue (EAT) may produce several cytokines contributed to coronary atherosclerosis. EAT was measured by transthoracic echocardiography or 3 dimensional cardiac computed tomography (CT) on previous studies. We aimed to evaluate the correlation between EAT thickness and cardiovascular risk factors in healthy adults. Method: We collected clinical, biochemical information from 469 subjects (371 men and 98 women) who visited our health promotion center. EAT thickness was measured by chest CT on the free wall of the right ventricle. Result: The mean EAT thickness was 2.47 ± 1.64 mm in total of 469 subjects. EAT thickness was significantly correlated to age, weight, body mass index (BMI), total body fat, systolic and diastolic blood pressure, total cholesterol, low density lipoprotein (LDL)-cholesterol, and fasting glucose in men and to age, height, weight, BMI, total body fat, systolic and diastolic blood pressure, triglycerides, C-reactive protein (CRP), and fasting glucose in women. Multivariate analysis showed that age, BMI, systolic blood pressure, fasting glucose were the variables that independently correlated to EAT thickness in men. But there was no significant independent variable in women. Conclusion: In our study, EAT thickness measured with chest CT in healthy individuals correlates with cardiovascular risk factors in men. 展开更多
