Abstract
Aim: We investigated the direct effects of sevoflurane on angiogenesis and a variety of tumor cells. Materials & methods: The antiangiogenic activity of sevoflurane was determined using angiogenesis and biochemical assays. Results: Sevoflurane at low doses inhibits capillary network formation. Sevoflurane inhibited VEGF- and bFGF-stimulated migration, adhesion and growth in endothelial cells and induced apoptosis. Sevoflurane only at high doses inhibited growth and migration of tumor cells, suggesting differential effects of sevoflurane between endothelial and tumor cells. Mechanistically, sevoflurane decreased growth factors-induced Ras and Rac1 activation, and suppressed Ras and Rac1 signaling. Conclusion: We demonstrate the antiangiogenic effects of sevoflurane and provide preclinical evidence into the potential mechanisms by which sevoflurane may negatively affect cancer growth and metastasis.

Abstract
Purpose: Excessive inflammatory response is one of the possible pathogenic mechanisms of preeclampsia (PE). It remains unclear whether sevoflurane has an anti-inflammatory effect in human trophoblastic cells, which are corresponding to the dysfunction of placentas in PE. This study probed into the regulatory function of sevoflurane toward HTR8/SVneo cells so as to find PE pathology and PE treatment.Materials and methods: HTR8/SVneo cells were treated with sevoflurane, TNF-α with different concentrations, sevoflurane plus 10 ng/mL TNF-α and SB203580 plus 10 ng/mL TNF-α. Cell counting kit-8 (CCK-8) assays were performed to detect cell viability, while enzyme linked immunoSorbent assay (ELISA) was used to measure IL-6, IL-8, GM-CSF and MCP-1 levels in HTR8/SVneo cells. Besides, relative mRNA expression levels of IL-6 and IL-8 were tested via quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR), and p38 phosphorylation-related protein expressions were assessed through western blot.Results: Cell viability remained stable when HTR8/SVneo cells were treated with or without sevoflurane and SB203580 in inflammatory microenvironment created by TNF-α. MCP-1 and GM-CSF levels, as well as gene expressions of IL-6 and IL-8 in HTR8/SVneo cells were greatly increased by TNF-α (5, 10 and 20 ng/mL), but reversed by sevoflurane and SB203580. Simultaneously, TNF-α-induced phosphorylation of p38MAPK signaling pathway was inhibited by sevoflurane and SB203580.Conclusions: Sevoflurane inhibited inflammatory response induced by TNF-α in human trophoblastic cells HTR8/SVneo through suppressing the phosphorylation of p38MAPK signaling pathway.

Abstract
The vascular endothelium plays an essential role in vascular disease and cardiovascular diseases. The effects and underlying mechanisms of sevoflurane on vascular endothelial growth factor (VEGF) in human endothelial cells have not been elucidated. The MTT colorimetric assay was used to determine HUVEC activity at different concentrations (1 and 3%, respectively) of sevoflurane for different time-points (12, 24 and 48 h, respectively). The regulation of sevoflurane on the mRNA levels of VEGFa, VEGFb, VEGFc and VEGFR1, 2, 3 was analyzed by real-time PCR. When VEGFR2 was inhibited by axitinib, VEGFR2 protein expression was determined by western blotting, and the cell viability was assessed by MTT analysis. The results revealed that sevoflurane increased cell viability in a dose- and time-dependent manner. Sevoflurane significantly upregulated VEGFA mRNA expression only. In addition, sevoflurane increased the expression of VEGFR2 at the mRNA and protein levels, whereas sevoflurane did not modulate the mRNA expression of VEGFR1 and VEGFR3. Furthermore, sevoflurane failed to increase the mRNA and protein expression of VEGFR2 when VEGFR2 was inhibited by axitinib, an inhibitor of VEGF receptors. In conclusion, sevoflurane may be a promising agent against endothelium dysfunction-caused vascular disease by activating the VEGF-A/VEGFR2 signaling pathway.

Abstract
Background Anesthetic pre-conditioning attenuates inflammatory response during ischemia-reperfusion lung injury. The molecular mechanisms to explain it are not fully understood. The aim of our investigation was to analyze the molecular mechanism that explain the anti-inflammatory effects of anesthetic pre-conditioning with sevoflurane focusing on its effects on MAPKs (mitogen-activated protein kinases), NF-κB (nuclear factor kappa beta) pathways, and apoptosis in an experimental lung autotransplant model. Methods Twenty large white pigs undergoing pneumonectomy plus lung autotransplant were divided into two 10-member groups on the basis of the anesthetic received (propofol or sevoflurane). Anesthetic pre-conditioning group received sevoflurane 3% after anesthesia induction and it stopped when one-lung ventilation get started. Control group did not receive sevoflurane in any moment during the whole study period. Intracellular signal-transduction pathways (MAPK family), transcription factor (NF-κB), and apoptosis (caspases 3 and 9) were analyzed during experiment. Results Pigs that received anesthetic pre-conditioning with sevoflurane have shown significant lower values of MAPK-p38, MAPK-P-p38, JNK (c-Jun N-terminal kinases), NF-κB p50 intranuclear, and caspases (p < 0.05) than pigs anesthetized with intravenous propofol. Conclusions Lung protection of anesthetic pre-conditioning with sevoflurane during experimental lung autotransplant is, at least, partially associated with MAPKs and NF κB pathways attenuation, and antiapoptotic effects.

Abstract
Caveolins are involved in anaesthetic-induced cardioprotection. Actin filaments are located in close connection to Caveolins in the plasma membrane. We hypothesised that helium might affect the cytoskeleton and induce secretion of Caveolin. HCAEC, HUVEC and Cav-1 siRNA transfected HUVEC were exposed for 20 minutes to either helium (5% CO2, 25% O2, 70% He) or control gas (5% CO2, 25% O2, 70% N2). Cells and supernatants were collected for infrared Western blot analysis, immunofluorescence staining, nanoparticle tracking analysis and permeability measurements. Helium treatment increased the cortical localisation of F-actin fibers in HUVEC. After 6 hours, helium decreased cellular Caveolin-1 (Cav-1) levels and increased Cav-1 levels in the supernatant. Cell permeability was decreased 6 and 12 hours after helium treatment, and increased levels of Vascular Endothelial - Cadherin (VE-Cadherin) and Connexin 43 (Cx43) were observed. Transfection with Cav-1 siRNA abolished the effects of helium treatment on VE-Cadherin, Cx43 levels and permeability. Supernatant obtained after helium treatment reduced cellular permeability in remote HUVEC, indicating that increased levels of Cav-1 are responsible for the observed alterations. These findings suggest that Cav-1 is secreted after helium exposure in vitro, altering the cytoskeleton and increasing VE-Cadherin and Cx43 expression resulting in decreased permeability in HUVEC.

Abstract
Background Lipopolysaccharide (LPS) was shown to induce an increase in caveolin-1 (Cav-1) expression in endothelial cells; however, the mechanisms regarding this response and the consequences on caveolae-mediated transcellular transport have not been completely investigated. This study aims to investigate the role of LPS-induced Cav-1 phosphorylation in pulmonary microvascular permeability in pulmonary microvascular endothelial cells (PMVECs). Methods Rat PMVECs were isolated, cultured, and identified. Endocytosis experiments were employed to stain the nuclei by DAPI, and images were obtained with a fluorescence microscope. Permeability of endothelial cultures was measured to analyze the barrier function of endothelial monolayer. Western blot assay was used to examine the expression of Cav-1, pCav-1, triton-insoluble Cav-1, and triton-soluble Cav-1 protein. Results The LPS treatment induced phosphorylation of Cav-1, but did not alter the total Cav-1 level till 60 min in both rat and human PMVECs. LPS treatment also increased the triton-insoluble Cav-1 level, which peaked 15 min after LPS treatment in both rat and human PMVECs. LPS treatment increases the intercellular cell adhesion molecule-1 expression. Src inhibitors, including PP2, PP1, Saracatinib, and Quercetin, partially inhibited LPS-induced phosphorylation of Cav-1. In addition, both PP2 and caveolae disruptor MβCD inhibited LPS-induced increase of triton-insoluble Cav-1. LPS induces permeability by activating interleukin-8 and vascular endothelial growth factor and targeting other adhesion markers, such as ZO-1 and occludin. LPS treatment also significantly increased the endocytosis of albumin, which could be blocked by PP2 or MβCD. Furthermore, LPS treatment for 15 min significantly elevated Evans Blue-labeled BSA transport in advance of a decrease in transendothelial electrical resistance of PMVEC monolayer at this time point. After LPS treatment for 30 min, transendothelial electrical resistance decreased significantly. Moreover, PP2 and MβCD blocked LPS-induced increase in Evans Blue-labeled BSA level. Conclusion Our study demonstrates that LPS-induced Cav-1 phosphorylation may lead to the increase of transcellular permeability prior to the increase of paracellular permeability in a Src-dependent manner. Thus, LPS-induced Cav-1 phosphorylation may be a therapeutic target for the treatment of inflammatory lung disease associated with elevated microvascular permeability.

Abstract
Endothelial dysfunction induced by oxidative stress and inflammation plays a critical role in the pathogenesis of cardiovascular diseases. The anesthetic sevoflurane confers cytoprotective effects through its anti-inflammatory properties in various pathologies such as systemic inflammatory response syndrome and ischemic-reperfusion injury but mechanism is unclear. We hypothesized that sevoflurane can protect against tumor necrosis factor (TNF)-α-induced endothelial dysfunction through promoting the production of endothelium-dependent nitric oxide (NO). Primary cultured human umbilical vein endothelial cells (HUVECs) were pretreated with different concentrations (0.5, 1.5 and 2.5 minimum alveolar concentration, MAC) of sevoflurane for 30 min before TNF-α (10 ng/mL) stimulation for 4 h. Sevoflurane pretreatment significantly reduced TNF-α-induced VCAM-1, ICAM-1, IκBα, and NF-κB activation, and blocked leukocytes adhesion to HUVECs. Meanwhile, sevoflurane (1.5 and 2.5 MAC) significantly induced endothelial nitric oxide synthase (eNOS) phosphorylation and enhanced NO levels both intracellularly and in the cell culture medium. All these cytoprotective effects of sevoflurane were abrogated by NG-nitro-l-arginine methyl ester (l-NAME), a non-specific nitric oxide synthase inhibitor. Collectively, these data indicate that sevoflurane protects against TNF-α -induced vascular endothelium dysfunction through activation of eNOS/NO pathway and inhibition of NF-κB.

Angiotensin-converting enzyme 2/angiotensin-(1-7)/Mas axis prevents lipopolysaccharide-induced apoptosis of pulmonary microvascular endothelial cells by inhibiting JNK/NF-κB pathways.

Abstract
ACE2 and Ang–(1–7) have important roles in preventing acute lung injury. However, it is not clear whether upregulation of the ACE2/Ang–(1–7)/Mas axis prevents LPS–induced injury in pulmonary microvascular endothelial cells (PMVECs) by inhibiting the MAPKs/NF–κB pathways. Primary cultured rat PMVECs were transduced with lentiviral–borne Ace2 or shRNA–Ace2, and then treated or not with Mas receptor blocker (A779) before exposure to LPS. LPS stimulation resulted in the higher levels of AngII, Ang–(1–7), cytokine secretion, and apoptosis rates, and the lower ACE2/ACE ratio. Ace2 reversed the ACE2/ACE imbalance and increased Ang–(1–7) levels, thus reducing LPS–induced apoptosis and inflammation, while inhibition of Ace2 reversed all these effects. A779 abolished these protective effects of Ace2. LPS treatment was associated with activation of the ERK, p38, JNK, and NF–κB pathways, which were aggravated by A779. Pretreatment with A779 prevented the Ace2–induced blockade of p38, JNK, and NF–κB phosphorylation. However, only JNK inhibitor markedly reduced apoptosis and cytokine secretion in PMVECs with Ace2 deletion and A779 pretreatment. These results suggest that the ACE2/Ang–(1–7)/Mas axis has a crucial role in preventing LPS–induced apoptosis and inflammation of PMVECs, by inhibiting the JNK/NF–κB pathways.

Abstract
We evaluated whether isoflurane, halothane and sevoflurane attenuate the inflammatory response and improve lung morphofunction in experimental asthma. Fifty-six BALB/c mice were sensitised and challenged with ovalbumin and anaesthetised with isoflurane, halothane, sevoflurane or pentobarbital sodium for one hour. Lung mechanics and histology were evaluated. Gene expression of pro-inflammatory (tumour necrosis factor-α), pro-fibrogenic (transforming growth factor-β) and pro-angiogenic (vascular endothelial growth factor) mediators, as well as oxidative process modulators, were analysed. These modulators included nuclear factor erythroid-2 related factor 2, sirtuin, catalase and glutathione peroxidase. Isoflurane, halothane and sevoflurane reduced airway resistance, static lung elastance and atelectasis when compared with pentobarbital sodium. Sevoflurane minimised bronchoconstriction and cell infiltration, and decreased tumour necrosis factor-α, transforming growth factor-β, vascular endothelial growth factor, sirtuin, catalase and glutathione peroxidase, while increasing nuclear factor erythroid-2-related factor 2 expression. Sevoflurane down-regulated inflammatory, fibrogenic and angiogenic mediators, and modulated oxidant-antioxidant imbalance, improving lung function in this model of asthma.

Abstract
Background Nuclear factor kappa B (NF-κB) has been implicated in anesthetic preconditioning (APC) induced protection against anoxia and reoxygenation (A/R) injury. The authors hypothesized that desflurane preconditioning would induce NF-κB oscillation and prevent endothelial cells apoptosis. Methods A human umbilical vein endothelial cells (HUVECs) A/R injury model was used. A 30 minute desflurane treatment was initiated before anoxia. NF-κB inhibitor BAY11-7082 was administered in some experiments before desflurane preconditioning. Cells apoptosis was analyzed by flow cytometry using annexin V–fluorescein isothiocyanate staining and cell viability was evaluated by modified tertrozalium salt (MTT) assay. The cellular superoxide dismutases (SOD) activitiy were tested by water-soluble tetrazolium salt (WST-1) assay. NF-κB p65 subunit nuclear translocation was detected by immunofluorescence staining. Expression of inhibitor of NF-κB-α (IκBα), NF-κB p65 and cellular inhibitor of apoptosis 1 (c-IAP1), B-cell leukemia/lymphoma 2 (Bcl-2), cysteine containing aspartate specific protease 3 (caspases-3) and second mitochondrial-derived activator of caspase (SMAC/DIABLO) were determined by western blot. Results Desflurane preconditioning caused phosphorylation and nuclear translocation of NF-κB before anoxia, on the contrary, induced the synthesis of IκBα and inhibition of NF-κB after reoxygenation. Desflurane preconditioning up-regulated the expression of c-IAP1 and Bcl-2, blocked the cleavage of caspase-3 and reduced SMAC release, and decreased the cell death of HUVECs after A/R. The protective effect was abolished by BAY11-7082 administered before desflurane. Conclusions The results demonstrated that desflurane activated NF-κB during the preconditioning period and inhibited excessive activation of NF-κB in reperfusion. And the oscillation of NF-κB induced by desflurane preconditioning finally up-regulated antiapoptotic proteins expression and protected endothelial cells against A/R.
