Wang R, Lin L, Han Y, Li Z, Zhen J, Zhang Y, Sun F, Lu Y. Exosome-delivered miR-153 from Trichinella spiralis promotes apoptosis of intestinal epithelial cells by downregulating Bcl2. Vet Res 2023; 54:52. [PMID: 37381058 DOI: 10.1186/s13567-023-01186-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 05/22/2023] [Indexed: 06/30/2023] Open
Abstract
Trichinellosis, a helminthic zoonosis, exhibits a cosmopolitan distribution and is a public health concern. In previous studies, it was reported that the exosomes secreted by Trichinella spiralis larvae (TsExos) largely affected cell biological activities. miRNAs, as exosome-delivered cargoes, affect the biological activities of the host by targeting genes. The present study aimed to elucidate the mechanisms by which miRNAs interact with intestinal epithelial cells. First, a miRNA library of TsExos was constructed; then, based on high-throughput miRNA sequencing results, miR-153 and its predicted target genes, namely, Agap2, Bcl2 and Pten, were selected for follow-up studies. The dual-luciferase reporter assays revealed that miR-153 directly targeted Bcl2 and Pten. Furthermore, real-time qPCR and Western blotting revealed that only Bcl2 was downregulated by TsExo-delivered miR-153 in porcine intestinal epithelial cells (IPEC-J2). Bcl2, an important antiapoptotic protein, plays an essential role in cell apoptosis as a common intersecting molecule of various signal transduction pathways. Therefore, we hypothesized that miR-153 derived from TsExos causes cell apoptosis by targeting Bcl2. The results suggested that miR-153 could induce apoptosis, reduce mitochondrial membrane potential, affect cell proliferation, and cause damage and substantial oxidative stress. Furthermore, miR-153 coincubated with IPEC-J2 cells stimulated the accumulation of the proapoptotic proteins Bax and Bad, which belong to the Bcl2 family of proteins, and the apoptosis-implementing proteins Caspase 9 and Caspase 3. Moreover, studies have suggested that miR-153 can promote apoptosis by regulating the MAPK and p53 signalling pathways involved in apoptosis. Thus, exosome-mediated miR-153 delivery secreted by T. spiralis could induce apoptosis and affect the MAPK and p53 signalling pathways by downregulating Bcl2 in IPEC-J2 cells. The study highlights the mechanisms underlying the invasion of T. spiralis larva.

Dimethyloxalylglycine (DMOG), a Hypoxia Mimetic Agent, Does Not Replicate a Rat Pheochromocytoma (PC12) Cell Biological Response to Reduced Oxygen Culture. Biomolecules 2022; 12:biom12040541. [PMID: 35454130 PMCID: PMC9027160 DOI: 10.3390/biom12040541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 03/25/2022] [Accepted: 03/30/2022] [Indexed: 02/01/2023] Open
Abstract
Cells respond to reduced oxygen availability predominately by activation of the hypoxia-inducible factor (HIF) pathway. HIF activation upregulates hundreds of genes that help cells survive in the reduced oxygen environment. The aim of this study is to determine whether chemical-induced HIF accumulation mimics all aspects of the hypoxic response of cells. We compared the effects of dimethyloxalylglycine (DMOG) (a HIF stabiliser) on PC12 cells cultured in air oxygen (20.9% O2, AO) with those cultured in either intermittent 20.9% O2 to 2% O2 (IH) or constant 2% O2 (CN). Cell viability, cell cycle, HIF accumulation, reactive oxygen species (ROS) formation, mitochondrial function and differentiation were used to characterise the PC12 cells and evaluate the impact of DMOG. IH and CN culture reduced the increase in cell numbers after 72 and 96 h and MTT activity after 48 h compared to AO culture. Further, DMOG supplementation in AO induced a dose-dependent reduction in the increase in PC12 cell numbers and MTT activity. IH-cultured PC12 cells displayed increased and sustained HIF-1 expression over 96 h. This was accompanied by increased ROS and mitochondrial burden. PC12 cells in CN displayed little changes in HIF-1 expression or ROS levels. DMOG (0.1 mM) supplementation resulted in an IH-like HIF-1 profile. The mitochondrial burden and action potential of DMOG-supplemented PC12 cells did not mirror those seen in other conditions. DMOG significantly increased S phase cell populations after 72 and 96 h. No significant effect on PC12 cell differentiation was noted with IH and CN culture without induction by nerve growth factor (NGF), while DMOG significantly increased PC12 cell differentiation with and without NGF. In conclusion, DMOG and reduced oxygen levels stabilise HIF and affect mitochondrial activity and cell behaviour. However, DMOG does not provide an accurate replication of the reduced oxygen environments.

Abstract
INTRODUCTION Numerous pieces of evidence demonstrated that isoflurane induces hippocampal cell injury and cognitive impairments. Picroside II has been investigated for its anti-apoptosis and antioxidant neuroprotective effects. We aimed to explore the protective effects of picroside II and the role of microRNA-195 (miR-195) on isoflurane-induced neuronal injury in rats. METHODS The Morris water maze test was used to evaluate the effects of isoflurane on rats regarding escape latency and time in quadrant parameters. Real-time quantitative PCR was used to detect the expression levels of miR-195 and pro-inflammatory cytokines, including inter-leukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) mRNA, in the hippocampal tissues and neuronal cells. RESULTS The picroside II significantly improves isoflurane-induced higher escape latency and lower time spent in the quadrant compared with the control rats. Picroside II also promotes cell viability and suppresses cell apoptosis of isoflurane-induced neuronal cells. Besides, picroside II suppresses the expression of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α) and miR-195 in vivo and in vitro. Furthermore, overexpression of miR-195 abrogates the effects of picroside II on the expression of pro-inflammatory cytokines. The appropriate dose of picroside II is 20 mg/kg. CONCLUSION Picroside II could protect the nervous system possibly through inhibiting the inflammatory response in the isoflurane-induced neuronal injury of rats. The protective effect of picroside II may be achieved by downregulating the expression of miR-195 and then inhibiting the inflammatory response.

Abstract
The report of bradycardia caused by propofol is increasing. In the experiment, we investigated the chronotropic function of propofol and the underlying mechanism. Rabbits of both sexes were randomly divided into 4 groups: propofol 5 mg/kg group, 10 mg/kg group, 15 mg/kg group, and sham group. Heart rate and frequency of vagal efferent discharge were recorded before the injection and 0, 0.5, 1, 2, and 10 min after the injection through intravenous mode. Then, their hearts were removed, and sinoatrial nodes were dissected. The action potentials of the sinus node pacemaker cells were recorded by the intracellular glass microelectrode technique, and the sinoatrial (SA) node was exposed to propofol 1, 3, 5, and 10 µM respectively. The action potentials were recorded after the sinoatrial nodes were exposed to each concentration of propofol for 15 min. Our results show that the heart rate significantly decreased, and the vagal efferent discharge was significantly increased at 0, 0.5, 1, and 2 min after the injection, respectively. Besides, as the dose increases, the magnitude of change shows a dose-dependent manner. Propofol exerts a negative chronotropic action on sinoatrial node pacemaker cells. The drug significantly decreased APA, VDD, RPF, and prolonged APD90 in a concentration-dependent manner. These effects may be the main mechanism of propofol-induced bradycardia in clinical study.

Abstract
BACKGROUND Propofol, a kind of intravenous sedative drug, is certified that exerts anti-inflammation and antitumor functions. However, the influence of propofol in cerebral injury and the corresponding mechanism remains unexplained, that our article focuses on. METHODS PC12 cells were treated with propofol and exposed in glutamic acid (Glu) solutions. Cell viability, apoptotic potential, apoptosis-related and autophagy-linked proteins were tested via CCK-8, flow cytometry, and western blot assays. Reverse transcription-quantitative real-time PCR was utilized to test miR-19a expression in Glu-stimulated cells. Next, miR-19a mimic transfection was used to assess the effects of miR-19a on cell apoptosis and autophagy in Glu or propofol treated cells. Finally, western blot was performed to test AMPK and mTOR pathways. RESULTS Glu exposure promoted cell apoptosis and autophagy of PC12 cells, while propofol attenuated cell apoptosis and autophagy triggered by Glu. Additionally, propofol decreased the miR-19a expression in Glu-stimulated PC12 cells. Meanwhile, over-expression of miR-19a reversed the effects of propofol on Glu-induced cell apoptosis and autophagy. Moreover, propofol potentiated AMPK and mTOR pathways in Glu-stimulated PC12 cells via impeding miR-19a expression. CONCLUSIONS These finding revealed that propofol relieved Glu-triggered apoptosis and autophagy of PC12, and activated AMPK and mTOR pathways by suppressing miR-19a expression.

Abstract
Propofol, a generally used anaesthetic in patients care, has been proven to induce neurotoxicity. Studies have shown that miR-363-3p was closely related to neurological dysfunction, and the up-regulated miR-363-3p was recognized to be participate in propofol-induced neurotoxicity. However, the mechanisms and functions of miR-363-3p in propofol-induced neurotoxicity remain rarely reported. The aim of our research was to clarify the potential effects of miR-363-3p in neurotoxicity induced by propofol. SH-SY5Y cells were treated with propofol, miR-363-3p inhibitor or sh-CREB. quantitative real-time polymerase chain reaction and western blotting were applied to detect the expression of miR-363-3p, CREB, Bax, Bcl-2, cleaved caspase-9 and cleaved caspase-3 at the mRNA and/or protein level, respectively. The levels of lactate dehydrogenase (LDH), superoxide dismutase (SOD) and malondialdehyde (MDA) in cell supernatant were detected using different kits. Flow cytometry and MTT assay were applied for assessing the functions of miR-363-3p and CREB on cell ability in cellular activity and apoptotic rate. In addition, Bioinformatic analysis and luciferase assay verified the relationship between 3'-UTR of CREB and miR-363-3p. Our data indicated that the cell viability decreased with the increasing propofol concentration. Bioinformatic analysis and luciferase assay suggested that 3'-UTR of transcript of CREB might be a binding site of miR-363-3p, and miR-363-3p could negatively regulate the expression of CREB. The changes in reactive oxygen species, LDH, SOD and MDA suggested that propofol mediates oxidative stress and apoptosis via modulating miR-363-3p/CREB axis. Propofol induces oxidative stress and apoptosis via affecting miR-363-3p/CREB axis in SH-SY5Y cells, suggesting miR-363-3p down-regulation may act as a novel strategy to ameliorate the propofol-induced neurotoxicity. Significance of the study: The present study demonstrated that propofol induces oxidative stress and apoptosis via affecting miR-363-3p/CREB axis in SH-SY5Y cells, suggesting miR-363-3p down-regulation may act as a novel strategy to ameliorate the propofol-induced neurotoxicity.

Abstract
Hypoxia induces cellular oxidative stress that is associated with neurodegenerative diseases. HPN (4'-hydroxyl-2-substituted phenyl nitronyl nitroxide), a stable nitronyl nitroxide, has excellent free radical scavenging properties. The purpose of this study was to investigate the protective effects of HPN on hypoxia-induced damage in PC12 cells. It was shown that HPN significantly attenuated hypoxia-induced loss of cell viability, release of lactate dehydrogenase (LDH), and morphological changes in PC12 cells. Moreover, hypoxic PC12 cells had increased levels of reactive oxygen species (ROS), malondialdehyde (MDA), and expression of HIF-1α and VEGF, but had reduced levels of superoxide dismutase (SOD) and catalase (CAT), and HPN reversed these changes. HPN also inhibited hypoxia-induced cell apoptosis via suppressing the expression of Bax, cytochrome c, and caspase-3, and inducing the expression of Bcl-2. These results indicate that the protective effects of HPN on hypoxia-induced damage in PC12 cells is associated with the suppression of hypoxia-induced oxidative stress and cell apoptosis. HPN could be a promising candidate for the development of a novel neuroprotective agent.

Abstract
Exosomes and extracellular nanovesicles (NV) derived from mesenchymal stem cells (MSC) may be used for the treatment of ischemic stroke owing to their multifaceted therapeutic benefits that include the induction of angiogenesis, anti-apoptosis, and anti-inflammation. However, the most serious drawback of using exosomes and NV for ischemic stroke is the poor targeting on the ischemic lesion of brain after systemic administration, thereby yielding a poor therapeutic outcome. In this study, we show that magnetic NV (MNV) derived from iron oxide nanoparticles (IONP)-harboring MSC can drastically improve the ischemic-lesion targeting and the therapeutic outcome. Because IONP stimulated expressions of therapeutic growth factors in the MSC, MNV contained greater amounts of those therapeutic molecules compared to NV derived from naive MSC. Following the systemic injection of MNV into transient middle-cerebral-artery-occlusion (MCAO)-induced rats, the magnetic navigation increased the MNV localization to the ischemic lesion by 5.1 times. The MNV injection and subsequent magnetic navigation promoted the anti-inflammatory response, angiogenesis, and anti-apoptosis in the ischemic brain lesion, thereby yielding a considerably decreased infarction volume and improved motor function. Overall, the proposed MNV approach may overcome the major drawback of the conventional MSC-exosome therapy or NV therapy for the treatment of ischemic stroke.

Abstract
Administration of propofol at the time of reperfusion has shown to protect the heart from ischemia and reperfusion (I/R) injury. The aim of the present study was to investigate the molecular mechanism underling the cardioprotective effect of propofol against myocardial I/R injury (MIRI) in vivo and in vitro. Rat heart I/R injury was induced by ligation of the left anterior descending (LAD) artery for 30 min followed by 2-hr reperfusion. Propofol pretreatment (0.01 mg/g) was performed 10 min before reperfusion. In vitro MIRI was investigated in cultured cardiomyocytes H9C2 following hypoxia/reoxygenation (H/R) injuries. Propofol pretreatment in vitro was achieved in the medium supplemented with 25 μmol/L propofol before H/R injuries. Propofol pretreatment significantly increased miRNA-451 expression, decreased HMGB1 expression, reduced infarct size, and I/R-induced cardiomyocyte apoptosis in rat hearts undergoing I/R injuries. Knockdown of miRNA-451 48 hr before I/R injury was found to increase HMGB1 expression, infarct size, and I/R-induced cardiomyocyte apoptosis in rat hearts in the presence of propofol pretreatment. These in vivo findings were reproduced in vivo that knockdown of miRNA-451 48 hr before H/R injuries increased HMGB1 expression and H/R-induced apoptosis in cultured H9C2 supplemented with propofol. In addition, luciferase activity assays and gain-of-function studies found that propofol could decrease HMGB1, the target of miRNA-541. Taken together our findings provide a first demonstration that propofol-mediated cardioprotection against MIRI is dependent of microRNA-451/HMGB1. The study provides a novel target to prevent I/R injury during propofol anesthesia.

Abstract
To find the effect of Paris saponin VII (PS VII)-mediated PI3K/AKT/MAPK signaling pathway on the sensitivity of ADR-resistant HepG2 cell (HepG2/ADR) cells to ADR. The proliferation inhibitory rates were detected by using MTT assay. Flow cytometry was employed to examine the intracellular accumulation of ADR. The expressions of drug-resistant genes (P-gp, MRP and BCRP) were detected by qRT-PCR, cell apoptosis by Annexin-V-FITC/PI staining, and the expressions of drug-resistance-related proteins, apoptosis-related proteins, and PI3K/AKT/MAPK pathway-related proteins were determined by Western blotting. HepG2/ADR and HepG2 cells treated with PS VII (0.88, 1.32, 1.98, and 2.97 μM) for 48 hours showed increased proliferation inhibitory rate in a dose-dependent manner. HepG2/ADR cells treated PS VII (0.88, 1.32, 1.98 μM) for 48 hours showed decreased IC50 of ADR. Compared with HepG2/ADR cells treated with ADR (5 nM), those treated with PS VII (≤1.98 μM) and ADR (5 nM) showed enhanced ADR accumulation, decreased drug-resistant gene expressions, increased cell apoptosis with unregulated Bax and cleaved caspase-3 and downregulated Bcl-2, as well as the inhibition of PI3K/AKT/MAPK pathway. Moreover, the combination of ADR (5 nM), PS VII (1.98 μM), and LY294002 (PI3K/AKT inhibitor, 20 μM)/SB203580 (P38 inhibitor, 20 μM) for 48 hours could further decreased the HepG2/ADR cell viability, but induced cell apoptosis, accompanying with the decreased expressions of drug-resistant genes. PS VII could downregulate the expressions of drug-resistance genes, increase intracellular accumulation of ADR, promote cell apoptosis, and enhance the sensitivity of HepG2/ADR cells to ADR via PI3K/AKT/MAPK.
