Rosuvastatin alleviated the liver ischemia reperfusion injury by activating the expression of peroxisome proliferator-activated receptor gamma (PPARγ). J Bioenerg Biomembr 2021; 53:573-583.

Abstract
Liver ischemia and reperfusion could cause serious damage to liver tissues. Abnormal liver function could induce serious damage and threaten human health. Evidence emerged to suggest that rosuvastatin could relieve cerebral ischemia-reperfusion injury and alleviate the disease related to vessels by activating the expression of PPARγ. However, whether rosuvastatin could relieve the liver ischemia reperfusion injury by enhancing the expression of PPARγ is unclear. For the strictness of experimental findings, we established both the rat models and the cell model of liver ischemia reperfusion injury by respectively treating rats and cells with rosuvastatin. PPARγ inhibitor was also used for the stimulation of these cells and rats. Reactive oxygen species (ROS) levels, apoptosis and related protein levels were determined with ROS staining, ROS staining and western blotting for the detection of injury induced by oxygen-glucose deprivation and re-oxygenation (OGD/R). Pretreatment of rosuvastatin promoted the expression of PPARγ in liver tissues and MIHA cells. It also inhibited the ischemia reperfusion and OGD/R induced production of ROS while promoted the release of SOD in liver tissues and MIHA cells. Furthermore, rosuvastatin also alleviated the ischemia reperfusion -induced apoptosis of liver tissues and OGD/R-induced MIHA cells apoptosis. However, application of PPARγ inhibitor abolished the restorative effects of rosuvastatin on the apoptosis and oxidative stress on liver tissues and MIHA cells. Rosuvastatin prevented the liver ischemia reperfusion injury of rats by activating PPARγ.

Abstract
Ischemia-reperfusion injury (IRI) is a complex pathophysiological process that is often characterized as a blood circulation disorder caused due to various factors (such as traumatic shock, surgery, organ transplantation, burn, and thrombus). Severe metabolic dysregulation and tissue structure destruction are observed upon restoration of blood flow to the ischemic tissue. Theoretically, IRI can occur in various tissues and organs, including the kidney, liver, myocardium, and brain, among others. The advances made in research regarding restoring tissue perfusion in ischemic areas have been inadequate with regard to decreasing the mortality and infarct size associated with IRI. Hence, the clinical treatment of patients with severe IRI remains a thorny issue. Peroxisome proliferator-activated receptor γ (PPARγ) is a member of a superfamily of nuclear transcription factors activated by agonists and is a promising therapeutic target for ameliorating IRI. Therefore, this review focuses on the role of PPARγ in IRI. The protective effects of PPARγ, such as attenuating oxidative stress, inhibiting inflammatory responses, and antagonizing apoptosis, are described, envisaging certain therapeutic perspectives.

Abstract
Rosuvastatin has been found to possess antioxidant and anti-inflammatory properties. The aim of the current study was to evaluate whether rosuvastatin was effective in attenuating cardiac injury in lipopolysaccharide (LPS) - challenged mice and H9C2 cells and identify the underlying mechanisms, focusing on the nod-like receptor protein 3 (NLRP3)/toll-like receptor 4 (TLR4) pathway. Cardiac injury, cardiac function, apoptosis, oxidative stress, inflammatory response, and the NLRP3/TLR4 pathway were evaluated in both in vivo and in vitro studies. LPS-induced cardiomyocyte injury was markedly attenuated by rosuvastatin treatment, evidenced by increased cell proliferation of H9C2 cells, rescued cardiac function, and improved morphological changes in mice and reduced lactate dehydrogenase (LDH), creatine kinase MB fraction (CK-MB), and troponin I (cTnI) in serum. Apoptosis was clearly ameliorated in myocardial tissue and H9C2 cells co-treated with rosuvastatin. In addition, after LPS challenge, excessive oxidative stress was present, indicated by increases in malondialdehyde (MDA) content, NADPH activity, and reactive oxygen species (ROS) production and decreased superoxide dismutase (SOD) activity. Rosuvastatin improved all the indicators of oxidative stress, with an effect similar to that of N-acetylcysteine (NAC) (an ROS scavenger). Notably, LPS-exposed H9C2 cells and mice showed significant NLRP3 and TLR4/nuclear factor-κB (NF-κB) pathway activation and inflammatory responses. Administration of rosuvastatin reduced the increases in NLRP3, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC), pro-caspase-1, TLR4, and p65 expression and decreased the tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β), IL-18, and IL-6 contents, with an effect similar to that of MCC950 (an NLRP3 inhibitor). In conclusion, inhibition of the inflammatory response and oxidative stress contributes to cardioprotective effect of rosuvastatin against cardiac injury induced by LPS, and the effect of rosuvastatin was achieved through inactivation of the NF-κB/NLRP3 pathway.

Attenuation of the Na/K‑ATPase/Src/ROS amplification signaling pathway by astaxanthin ameliorates myocardial cell oxidative stress injury. Mol Med Rep 2020; 22:5125-5134. [PMID: 33173978 PMCID: PMC7646965 DOI: 10.3892/mmr.2020.11613] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 08/27/2020] [Indexed: 12/27/2022] Open
Abstract
The 3S, 3′S-ASTaxanthin (3S, 3′S-AST) isomer has strong antioxidant activity; however, its protective roles and potential mechanisms against oxidative stress damage in cardiomyocytes have not been investigated. Na+/K+-ATPase (NKA)/Src signal activation has an important role in increasing reactive oxygen species (ROS) production. The aim of the present study was to investigate the protective effects and mechanism of 3S, 3′S-AST on hydrogen peroxide (H2O2)-induced oxidative stress injury in H9c2 myocardial cells. The protective effects of 3S, 3′S-AST on H2O2-induced H9c2 cell injury was observed by measuring lactate dehydrogenase and creatine kinase myocardial band content, cell viability and nuclear morphology. The antioxidant effect was investigated by analyzing ROS accumulation and malondialdehyde, glutathione (GSH) peroxidase, GSH and glutathione reductase activity levels. The protein expression levels of Bax, Bcl-2, caspase-3 and cleaved caspase-3 were analyzed using western blotting to determine cardiomyocyte apoptosis. Western blot analysis of the phosphorylation levels of Src and Erk1/2 were also performed to elucidate the molecular mechanism involved. The results showed that 3S, 3′S-AST reduced the release of LDH and promoted cell viability, and attenuated ROS accumulation and cell apoptosis induced by H2O2. Furthermore, 3S, 3′S-AST also restored apoptosis-related Bax and Bcl-2 protein expression levels in H2O2-treated H9c2 cells. The phosphorylation levels of Src and Erk1/2 were significantly higher in the H2O2 treatment group, whereas 3S, 3′S-AST pretreatment significantly decreased the levels of phosphorylated (p)-Src and p-ERK1/2. The results provided evidence that 3S, 3′S-AST exhibited a cardioprotective effect against oxidative stress injury by attenuating NKA/Src/Erk1/2-modulated ROS amplification.

Abstract
Statins have been reported to suppress CD40 expression and nuclear factor (NF)-κB activation, which are both up-regulated in the intestines following traumatic brain injury (TBI)-induced intestinal injury. In this study, we aimed to investigate the effects of the statin rosuvastatin on post-TBI jejunal injury in rats, focusing on potential mechanisms involving the CD40/NF-κB signaling pathway. The jejunal CD40 expression was determined by western blotting. The DNA-binding activity of NF-κB was assessed by electrophoretic mobility shift assays (EMSAs). The tumor necrosis factor (TNF)-α and interleukin (IL)-1β levels were assessed by enzyme-linked immunosorbent assays (ELISAs). The severity of the jejunal mucosal injury was assessed by hematoxylin and eosin (HE) staining and histopathological evaluation. We found that the post-TBI upregulation of both CD40 expression and NF-κB activity in the jejunal tissues were significantly inhibited by rosuvastatin, while the post-TBI expression of TNF-α and IL-1β was significantly suppressed by rosuvastatin. In addition, rosuvastatin significantly ameliorated TBI-induced effects on the villus height, crypt depth, and villous surface area. Rosuvastatin suppressed TBI-induced intestinal injury in rats, which may be associated with the blockade of the CD40/NF-κB pathway.

Rosuvastatin protects isolated hearts against ischemia-reperfusion injury: role of Akt-GSK-3β, metabolic environment, and mitochondrial permeability transition pore. J Physiol Biochem 2020; 76:85-98.

Abstract
The cardioprotective activity of rosuvastatin (R) is yet to be known. The objective of this study was to research whether R perfusion before global ischemia can mitigate myocardial ischemia-reperfusion damage, considering the metabolic condition in which these effects occur, and to contemplate potential mitochondrial benefits. Protein kinase B (Akt)/glycogen synthase kinase-3β (GSK-3β) and mitochondrial permeability transition pore (MPTP) are key elements in myocardial injury produced by ischemia-reperfusion. Isolated rat hearts were subjected to 25-min ischemia and 1-h reperfusion in the presence or absence of R, with or without Wortmannin (W), a phosphatidylinositol 3-kinase (PI3K)/Akt inhibitor. Akt and GSK-3β were measured by Western blot analysis; lactate, glycogen, and G6PDH were determined; and Ca2+-induced MPTP opening was evaluated using a spectrophotometric method. Contractility was assessed by left ventricular developed pressure (LVDP), and rate-pressure product (RPP), peak rate of contraction and peak rate of relaxation (± dP/dt), and left ventricular end-diastolic pressure (LVEDP) were determined. Tissue samples were extracted to evaluate mitochondrial damage by electron microscopy and to assess infarct size. Statistical analysis employed ANOVA (n = 6/per group). Myocardial infarct size was significantly reduced by R, which also improved cardiac function. MPTP opening was delayed to 300 μM CaCl2, while use of W resulted in MPTP opening at 200 μM CaCl2. Electron microscopy showed better mitochondrial preservation with R, which reduced lactic acid production, increased glycogen consumption and G6PDH activity, as well as phosphorylation of Akt and GSK-3β. R before ischemia is cardioprotective against ischemic and reperfusion damage, activating Akt and regulating GSK-3β negatively and attenuating the MPTP opening.

Abstract
HMG-CoA reductase inhibitors, i.e. statins, are effective in reducing cardiovascular disease events but also in cardiac-related and overall mortality. Statins are in general well-tolerated, but currently the concerns are raised if statins may increase the risk of new-onset diabetes mellitus (NOD). In this review, the possible effects of statins on organs/tissues being involved in glucose metabolism, i.e. liver, pancreas, adipose tissue, and muscles, had been discussed. The net outcome seems to be inconsistent and often contradictory, which may be largely affected by in vitro experimental settings or/and in vivo animal conditions. The majority of studies point out statin-induced changes of regulations of isoprenoid metabolites and cell-associated cholesterol contents as predisposing factors related to the statin-induced NOD. On the other hand, it should be considered that dysfunctions of isoprenoid pathway and mitochondrial ATP production and the cholesterol homeostasis are already developed under (pre)diabetic and hypercholesterolemic conditions. In order to connect the basic findings with the clinical manifestation more clearly, further research efforts are needed.
