Nuclear receptor subfamily 4 group A member 1 promotes myocardial ischemia/reperfusion injury through inducing mitochondrial fission factor-mediated mitochondrial fragmentation and inhibiting FUN14 domain containing 1-depedent mitophagy.

This study investigated the mechanism by which NR4A1 regulates mitochondrial fission factor (Mff)-related mitochondrial fission and FUN14 domain 1 (FUNDC1)-mediated mitophagy following cardiac ischemia-reperfusion injury(I/R). Our findings showed that the damage regulation was positively correlated with the pathological fission and pan-apoptosis of myocardial cell mitochondria. Compared with wild-type mice (WT), NR4A1-knockout mice exhibited resistance to myocardial ischemia-reperfusion injury and mitochondrial pathological fission, characterized by mitophagy activation.

Omega-3 fatty acids and their influence on hypertension and coronary atherosclerosis: Insights from a Mendelian randomization approach.

It has been suggested that Omega-3 fatty acids may improve endothelial thickness and thereby reduce the onset of cardiovascular diseases such as coronary atherosclerosis and hypertension. However, published observational epidemiological studies on the relationship between cardiovascular disease (CVD) and Omega-3 fatty acids remain inconclusive. Here, we performed a two-sample Mendelian randomisation analysis using publicly available GWAS pooled statistics to study a GWAS dataset of 16 380 466 SNPs in 23 363 cases and 195 429 controls (also of European ancestry) to determine genetic susceptibility to hypertension.

The Potential Association of TFR1/SLC11A2/GPX4 with Ferroptosis in Mediating Lipid Metabolism Disorders in Atherosclerosis.

This study aims to investigate the molecular mechanisms and associated pathways by which iron accumulation may be involved in lipid metabolism abnormalities in atherosclerotic mice.

Methods: Relying on ApoE-/- mouse body position observation, blood biochemical analysis, oxidative stress test and aortic tissue sectioning techniques, the effects of ferroptosis on lipid metabolism in atherosclerotic mice were analyzed.

Emodin alleviates CRS4-induced mitochondrial damage via activation of the PGC1α signaling.

C57BL/6 mice with 5/6 nephrectomy and HL-1 cells stimulated with 5% CKD mouse serum were used for in vivo and in vitro experiments.

Natural products as pharmacological modulators of mitochondrial dysfunctions for the treatment of diabetes and its complications: An update since 2010.

Diabetes, characterized as a well-known chronic metabolic syndrome, with its associated complications pose a substantial and escalating health and healthcare challenge on a global scale.

Aberrant expression of HDL-bound microRNA induced by a high-fat diet in a pig model: implications in the pathogenesis of dyslipidaemia.

Background: A high-fat diet can affect lipid metabolism and trigger cardiovascular diseases. A growing body of studies has revealed the HDL-bound miRNA profiles in familial hypercholesterolaemia; in sharp contrast, relevant studies on high-fat diet-induced dyslipidaemia are lacking. In the current study, HDL-bound miRNAs altered by a high-fat diet were explored to offer some clues for elucidating their effects on the pathogenesis of dyslipidaemia.

Tanshinone IIA Combined With Cyclosporine A Alleviates Lung Apoptosis Induced by Renal Ischemia-Reperfusion in Obese Rats.

Acute lung injury (ALI), which is induced by renal ischemia-reperfusion (IR), is one of the leading causes of acute renal IR-related death. Obesity raises the frequency and severity of acute kidney injury (AKI) and ALI. Tanshinone IIA (TIIA) combined with cyclosporine A (CsA) was employed to lessen the lung apoptosis led by renal IR and to evaluate whether TIIA combined with CsA could alleviate lung apoptosis by regulating mitochondrial function through the PI3K/Akt/Bad pathway in obese rats.

Tanshinone IIA combined with CsA inhibit myocardial cell apoptosis induced by renal ischemia-reperfusion injury in obese rats.

Background: Acute myocardial injury (AMI), which is induced by renal ischemia-reperfusion (IR), is a significant cause of acute kidney injury (AKI)-related associated death. Obesity increases the severity and frequency of AMI and AKI. Tanshinone IIA (TIIA) combined with cyclosporine A (CsA) pretreatment was used to alleviate myocardial cell apoptosis induced by renal IR, and to determine whether TIIA combined with CsA would attenuate myocardial cell apoptosis by modulating mitochondrial function through the PI3K/Akt/Bad pathway in obese rats.

Gypenoside Inhibits Endothelial Cell Apoptosis in Atherosclerosis by Modulating Mitochondria through PI3K/Akt/Bad Pathway.

Atherosclerosis remains the most common cause of deaths worldwide. Endothelial cell apoptosis is an important process in the progress of atherosclerosis, as it can cause the endothelium to lose their capability in regulating the lipid homeostasis, inflammation, and immunity. Endothelial cell injury can disrupt the integrity and barrier function of an endothelium and facilitate lipid deposition, leading to atherogenesis.

As a malignant tumor, breast cancer is very prone to metastasis. Chemotherapy is one of the most common means for treating breast cancer. However, due to the serious metastasis and the poor targeting effect of traditional chemotherapeutic drugs, even after years of efforts, the therapeutic effect is still unsatisfied.
