Moreover, the anti-hyperlipidemic effects of sesamin are compared to those of other important sesame lignans like sesamolin and episesamin. Findings reveal that sesamin mainly exerts its anti-hyperlipidemic effects by targeting Δ5 desaturase, HMGCR, ABCA1 and ABCG1 through PPARα, PPARγ, LXRα, and SREBP signaling pathways. Overall, the amount of evidence supporting the anti-hyperlipidemic potential of sesamin in vitro and in vivo is compelling. A thorough understanding of the mechanisms underlying the anti-hyperlipidemic properties of sesamin is imperative for the possible employment of sesamin as an anti-hyperlipidemic and anti-atherogenic agent with minimal side effects.In a cell line, stably expressing α1A-adrenoceptors fused to the mCherry red fluorescent protein, noradrenaline, methoxamine, and oxymetazoline induced concentration-dependent increases in intracellular calcium. All of these agents increase α1A-adrenoceptor phosphorylation and internalization. Transient co-expression of these receptors with Rab proteins tagged with the enhanced Green Fluorescent Protein was employed to estimate α1A-adrenoceptor-Rab interaction using Förster Resonance Energy Transfer. Noradrenaline and methoxamine increased α1A-adrenoceptor interaction with Rab5 and Rab7 but did not modify it with Rab9. Oxymetazoline induced adrenoceptor interaction with Rab5 and Rab9 and only an insignificant increase in Rab7 signal. Phorbol myristate acetate increased α1A-adrenoceptor interaction with Rab5 and Rab9 but did not modify it with Rab7. The agonists and the active phorbol ester, all of which induce receptor phosphorylation and internalization, favor receptor interaction with Rab5, i.e., association with early endosomes. Cell stimulation with phorbol myristate acetate induced the α1A-adrenoceptors to interact with the late endosomal marker, Rab9, suggesting that the receptors are directed to slow recycling endosomes once they have transited to the Trans-Golgi network to be retrieved to the plasma membrane. The agonists noradrenaline and methoxamine likely induce a faster recycling and might direct some of the adrenoceptors toward degradation and/or very slow recycling to the plasma membrane. Oxymetazoline produced a mixed pattern of interaction with the Rab proteins. These data indicate that α1A-adrenoceptor agonists can trigger different vesicular traffic and receptor fates within the cells.Myocardial ischemia is the malperfusion of cardiac tissue due to a blockage in a coronary artery. Subsequent return of blood flow to the ischemic area of the heart, results in ischemia/reperfusion (I/R) injury in the heart and other organs, including the brain. Besides the cardioprotective effects of metformin on the heart against cardiac I/R injury, metformin also reduced neuronal injury in a stroke model. However, the effects of metformin on the brain following cardiac I/R injury has not yet been investigated. Therefore, we hypothesize that metformin reduces brain damage via decreasing brain mitochondrial dysfunction, microglial hyperactivity, and Alzheimer's proteins in rats after cardiac I/R injury. Proteases inhibitor Rats (n = 50) received either a sham operation (n = 10) or cardiac I/R (n = 40). Cardiac I/R was induced by 30 min of cardiac ischemia, followed by 120 min of reperfusion. Rats in cardiac I/R group were divided into 4 groups (n = 10/group); vehicle, metformin 100 mg/kg, metformin 200 mg/kg, and metformin 400 mg/kg. Metformin was given via femoral vein at 15 min prior to cardiac ischemia. At the end of reperfusion, brains were removed to determine dendritic spine density, brain mitochondrial function, microglial morphology, and amyloid beta formation. Cardiac I/R injury led to brain mitochondrial dysfunction, microglial hyperactivation, amyloid beta formation, Tau hyperphosphorylation, and reduced dendritic spine density with an increase in AMPK activation. All doses of metformin improved brain pathologies in rats with cardiac I/R injury possibly via activating cerebral AMPK. In summary, pre-treatment with metformin offers neuroprotection against the brain damages caused by cardiac I/R injury.Multiple organ failure in COVID-19 patients is a serious problem which can result in a fatal outcome. Damage to organs and tissues, including general lung dysfunction, develops as a consequence of ischemia, which, in turn, is caused by thrombosis in small blood vessels and hypoxia, leading to oxidative stress and inflammation. Currently, research is underway to screen existing drugs for antioxidant, antiplatelet and anti-inflammatory properties. Having studied the available publications concerning the mechanisms of damage to tissues and organs of patients with COVID-19, as well as the available treatment strategies, we propose to investigate salicyl-carnosine as a potential drug for treating COVID-19 patients. In a recent study, we described the drug's synthesis procedure, and showed that salicyl-carnosine possesses antioxidant, anti-inflammatory, and antiplatelet effects. Therefore, it can simultaneously act on the three pathogenetic factors involved in tissue and organ damage in COVID-19. Thus, we propose to consider salicyl-carnosine as a potential drug for the treatment of patients with severe cases of COVID-19 infection.Glucagon-like peptide 1 (GLP-1) receptor agonists are popular antidiabetic drugs with potent glucose-lowering effects and low risk of hypoglycemia. Animal experiments and human data indicate that tolerance develops toward at least some of their effects, e.g., gastric motility. Whether tolerance develops toward the glucose-lowering effect of GLP-1 receptor agonists in mice has never been formally tested. The hypothesis of tolerance development in mice will be reported in this study. The direct glucose-lowering effect of the GLP-1 receptor agonists was measured in non-fasted mice and with intraperitoneal glucose tolerance test. Exenatide (10 μg/kg) and liraglutide (600 μg/kg) both substantially lost efficacy during the 18-day treatment as compared to the acute effect. We conclude that our results demonstrate development of tolerance toward GLP-1 receptor agonists' glucose-lowering effect in mice.
