[PMID: 38781730 PMCID: PMC11145555 DOI: 10.1016/j.redox.2024.103197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 05/12/2024] [Accepted: 05/15/2024] [Indexed: 05/25/2024] Open
Abstract
Astrocytes are the major glial cells in the human brain and provide crucial metabolic and trophic support to neurons. The amyloid-β peptide (Aβ) alter the morphological and functional properties of astrocytes and induce inflammation and calcium dysregulation, contributing to Alzheimer's disease (AD) pathology. Recent studies highlight the role of Toll-like receptor (TLR) 4/nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling in inflammation. Reactive oxygen species (ROS) generated due to Aβ, induce apoptosis in the brain cells worsening AD progression. Astrocytic cell surface receptors, such as purinergic receptors (P2Y1 and P2Y2), metabotropic glutamate receptor (mGLUR)5, α7 nicotinic acetylcholine receptor (α7nAChR), and N-methyl-d-aspartate receptors (NMDARs), have been suggested to interact with inositol trisphosphate receptor (IP3R) on the endoplasmic reticulum (ER) to induce Ca2+ movement from ER to cytoplasm, causing Ca2+ dysregulation. We found that the citrus flavonoid nobiletin (NOB) protected primary astrocytes from Aβ42-induced cytotoxicity and inhibited TLR4/NF-κB signaling in Aβ42-induced primary rat astrocytes. NOB was found to regulate Aβ42-induced ROS levels through Keap1-Nrf2 pathway. The receptors P2Y1, P2Y2, mGLUR5, α7nAChR, and NMDARs induced intracellular Ca2+ levels by activating IP3R and NOB regulated them, thereby regulating intracellular Ca2+ levels. Molecular docking analysis revealed a possible interaction between NOB and IP3R in IP3R regulation. Furthermore, RNA sequencing revealed various NOB-mediated biological signaling pathways, such as the AD-presenilin, AD-amyloid secretase, and Wnt signaling pathway, suggesting possible neuroprotective roles of NOB. To conclude, NOB is a promising therapeutic agent for AD and works by modulating AD pathology at various levels in Aβ42-induced primary rat astrocytes.

Neurochem Res 2024; 49:1105-1120. [PMID: 38289520 DOI: 10.1007/s11064-024-04108-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 01/11/2024] [Accepted: 01/17/2024] [Indexed: 02/29/2024]
Abstract
Reduced myelin stability observed in the early stages of Alzheimer's disease leads to spatial learning and memory impairment. Exercise has been shown to protect nerves, reduce the risk of Alzheimer's disease, and strengthen synaptic connectivity. However, the underlying mechanisms of how exercise can promote myelin repair and coordinate inflammation and proliferation are still uncertain. In this study, we conducted histological and biochemical assays of cortical lysates after behavioral testing to detect pathological changes, myelin sheath thickness, and mRNA and protein levels. It is notable that D-galactose model mice exhibited elevated miRNA-34a levels, overactive astrocytes, decreased myelin staining scores, increased apoptosis, and decreased synaptic plasticity in the brain. Significantly, after eight weeks of exercise, we observed improvements in LFB scores, NeuN( +) neuron counts, and myelin basic protein (MBP) expression. Additionally, exercise promoted the expression of oligodendrocyte markers Olig2 and PDFGR-α associated with brain proliferation, and improved spatial cognitive function. Furthermore, it decreased the inflammation caused by astrocyte secretions (TNF-α, Cox-2, CXCL2). Interestingly, we also observed downregulation of miR-34a and activation of the TAN1/PI3K/CREB signaling pathway. Our data shed light on a previously unsuspected mechanism by which exercise reduces miR-34a levels and protects neuronal function and survival by preventing excessive demyelination and inflammatory infiltration in the CNS.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116767. [PMID: 37331453 DOI: 10.1016/j.jep.2023.116767] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 06/08/2023] [Accepted: 06/08/2023] [Indexed: 06/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inflammation and subepithelial fibrosis play major roles in the early pathology of eosinophilic esophagitis (EoE). However, there are currently no pharmacotherapeutic interventions that directly target eosinophilic esophagitis. Citri Reticulatae Pericarpium (CRP, known as Chen-Pi) is one of most frequently used qi-regulating drugs in Chinese medicine and nutrition. CRP is rich with flavonones and polymethoxy flavones, both of which exhibit superior anti-inflammatory, anti-allergic and anti-fibrosis effects. This study is to investigate intervention effect of CRP on EoE, to identify its active compounds and to explore its underlying mechanisms. METHODS The CRP extract was obtained by liquid-liquid extraction with 70% ethanol, and its main components were identified by HPLC and TLC chromatography as hesperidin, nobiletin, tangeretin, and narirutin in turn. Furthermore, we evaluated its effect and underlying mechanisms in an PN (Peanut protein extract)-sensitized murine model of food allergy induced EoE. RESULTS CRP treatment attenuated EoE model mice symptomatology, blocked hypothermia, reduced the production of PN-specific IgE and IgG1 and TH2 cytokines (interleukin (IL)-4 and IL-5), and increased the level of anti-inflammatory cytokines IL-10 and interferon (IFN)-γ. CRP treatment also significantly alleviated the pathological damage and reduced fibrosis in inflamed tissues like esophagus, lung, and intestine. These results were strongly associated with reducing the expression of p-p38 mitogen-activated protein kinase (MAPK), transforming growth factor beta1 (TGF-β1) and p-Smad 3 proteins. CONCLUSION CRP extract markedly inhibited TH2 immune response and attenuated subepithelial fibrosis with a dose-dependent manner through down-regulating MAPK/TGF-β signaling pathway. It is suggested that CRP extract might serve as a potential therapy for food allergy-induced EoE like disease.

Abstract
In recent years, the role of nobiletin in neuronal disorders has received extensive attention. However, the study of nobiletin in the peripheral nervous system is limited. Nobiletin, as a compound with high fat solubility, high bioavailability and low toxicity, has been extensively studied. Accumulating scientific evidence has shown that nobiletin has a variety of biological functions in the nervous system, such as inhibiting the expression of inflammatory factors, reducing the neurotoxic response, improving the antioxidant capacity, promoting the survival of nerve cells, promoting axon growth, reducing blood‒brain barrier permeability, reducing brain oedema, promoting cAMP response element binding protein expression, improving memory, and promoting mild depolarization of nerve cell mitochondria to improve antioxidative stress capacity. Accumulating studies have shown that nobiletin also protects enteric nervous system, spinal cord and sciatic nerve. To explore the new therapeutic potential of nobiletin in the nervous system, recent and relevant research progress is reviewed in this article. This will provide a new research idea for nobiletin in the nervous system.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease that primarily affects the synovial joints. RA has well-known clinical manifestations and can cause progressive disability and premature death along with socioeconomic burdens. Interleukin-6 (IL-6) has been implicated in the pathology of RA where it can stimulate pannus formation, osteoclastogenesis, and oxidative stress. Flavonoids are plant metabolites with beneficial pharmacological effects, including anti-inflammatory, antioxidant, antidiabetic, anticancer, and others. Flavonoids are polyphenolic compounds found in a variety of plants, vegetables, and fruits. Many flavonoids have demonstrated anti-arthritic activity mediated mainly through the suppression of pro-inflammatory cytokines. This review thoroughly discusses the accumulate data on the role of flavonoids on IL-6 in RA.

Abstract
BACKGROUND Testicular injury is one of the most serious problems associated with diabetes mellitus. The present study aimed to compare the effects of two different doses of nobiletin and analyze its mechanisms of action against diabetes-induced testicular impairment in rats. METHODS AND RESULTS Streptozotocin injection was used to induce diabetes. Diabetic rats received nobiletin orally at 10 or 25 mg/kg daily for 30 days. Diabetic rats displayed significant elevations in glucose, glycosylated hemoglobin (HbA1c), Homeostatic Model of Insulin Resistance (HOMA-IR), and pro-inflammatory cytokines, while the serum levels of insulin, testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were significantly reduced. Histological changes to positivity for caspase-3 and decreased androgen receptors (AR) immunoexpression were observed in diabetic rats. Both doses of nobiletin improved hyperglycemia, reduced pro-inflammatory cytokines, and augmented insulin, testosterone, LH, and FSH levels. LH and FSH receptors and cytochrome P450 17 α-hydroxylase (CYP17A1) were markedly downregulated in terms of both gene and protein expression in testicular tissues of the diabetic group, effects that were markedly ameliorated with both doses of nobiletin. In addition, both doses significantly reduced lipid peroxidation and caspase-3 immunoexpression and improved the activity of the antioxidant enzymes and AR in testicular tissues of the diabetic group. CONCLUSION Both nobiletin doses showed protective effects against diabetes-induced testicular injury by reducing oxidative stress, hyperglycemia, inflammation, and caspase-3 and upregulating the hypophysis-gonadal axis and AR. The high dose of nobiletin was more effective than the lower one.

Abstract
Skin cancer is one of the most dangerous diseases, leading to massive losses and high death rates worldwide. Topical delivery of nutraceuticals is considered a suitable approach for efficient and safe treatment of skin cancer. Nobiletin; a flavone occurring in citrus fruits has been reported to inhibit proliferation of carcinogenesis since 1990s, is a promising candidate in this regard. Nobiletin was loaded in various vesicular systems to improve its cytotoxicity against skin cancer. Vesicles were prepared using the thin film hydration method, and characterized for particle size, zeta potential, entrapment efficiency, TEM, ex-vivo skin deposition and physical stability. Nobiletin-loaded composite penetration enhancer vesicles (PEVs) and composite transfersomes exhibited particle size 126.70 ± 11.80 nm, 110.10 ± 0.90 nm, zeta potential + 6.10 ± 0.40 mV, + 9.80 ± 2.60 mV, entrapment efficiency 93.50% ± 3.60, 95.60% ± 1.50 and total skin deposition 95.30% ± 3.40, 100.00% ± 2.80, respectively. These formulations were selected for cytotoxicity study on epidermoid carcinoma cell line (A431). Nobiletin-loaded composite PEVs displayed the lowest IC50 value, thus was selected for the in vivo study, where it restored skin condition in DMBA induced skin carcinogenesis mice, as delineated by histological and immuno-histochemical analysis, biochemical assessment of skin oxidative stress biomarkers, in addition to miRNA21 and miRNA29A. The outcomes confirmed that nobiletin- loaded composite PEVs is an efficient delivery system combating skin cancer.

Abstract
OBJECTIVES This study was designed to investigate the possible antioxidant, antiapoptotic and neuroprotective effects of nobiletin on cisplatin-induced neurotoxicity rat model by evaluating neurotrophins, antioxidants and histopathology. METHODS Forty male Wistar Albino rats were divided into four groups: control, cisplatin (CIS), cisplatin + nobiletin (CIS + NOB) and nobiletin + cisplatin (NOB + CIS). CIS + NOB was applied nobiletin (10 mg/kg, i.p.) during the last four days whereas NOB + CIS was applied nobiletin during the first four days of the study. Cisplatin (4 mg/kg, i.p. twice a day) was administered to the experimental groups on the 5th day of the study. All rats were sacrificed on the 10th day of the study. BDNF, NGF, G6PD, GPx, tGSH and MDA levels were determined in brain. In addition, routin histolopathological analysis and caspase-3 immunoreactivity assay were conducted. RESULTS BDNF concentrations increased in nobiletin-administered groups, compared to Control and CIS and that the increase was statistically significant in NOB + CIS (p < 0.05). It was also found that G6PD activity increased (p < 0.05) in the nobiletin-administered groups, compared to control and CIS. Histopathologically, neuronal degeneration, oedema and gliosis increased in CIS compared to Control, and nobiletin administration decreased neuronal degeneration and oedema compared to CIS (p < 0.05). Cisplatin increased (p < 0.05) caspase-3 immunoreactivity in cerebrovascular endothelium and neurons compared to Control, while nobiletin administration decreased caspase-3 immunoreactivity in cerebrovascular endothelium. Caspase-3 immunoreactivity in neurons decreased only in NOB + CIS (p < 0.05). CONCLUSION Nobiletin increased BDNF concentration and G6PD activity in brain and when evaluated together with histopathological and immunohistochemical findings, it may have antioxidant, antiapoptotic and neuroprotective effects against cisplatin.

Abstract
Nonylphenol (NP) is an environmental contaminant, which adversely affects the male fertility due to endocrine disruption and generation of oxidative stress. The current research was planned to assess the effects of nobiletin (NOB), a polymethoxyflavone, on NP-induced testicular damages. Twenty-four male rats were divided into 4 groups: control (0.1% DMSO), NP group (50 mg/kg), NP+NOB group (50 mg/kg + 25 mg/kg), and NOB group (25 mg/kg). Our results revealed that NP brought down the activities of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GSR), while elevated the level of thiobarbituric acid reactive substances (TBARS). Additionally, NP decreased the level of follicle-stimulating hormone (FSH), luteinizing hormone (LH), plasma testosterone, daily sperm production (DSP), epididymal sperm count, viability, motility, gene expression of testicular steroidogenic enzymes (StAR, 3β-HSD and 17β-HSD) and anti-apoptotic protein (Bcl-2), as well as number of spermatogenic cells belonging to various stages. Whereas, sperm (head, mid-piece/neck and tail) abnormalities, expression of apoptotic proteins (Bax and caspase-3), and histopathological damages were increased. However, NOB remarkably reversed all the damages caused by NP. Therefore, it is deduced that NOB could be used as a potential therapeutic to counter the NP-prompted oxidative stress and apoptotic damages in testes.

Life Sci 2020; 266:118876. [PMID: 33310035 DOI: 10.1016/j.lfs.2020.118876] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 11/22/2020] [Accepted: 12/01/2020] [Indexed: 10/22/2022]
Abstract
Prenatal exposure to arsenic is demonstrated to elevate the risk of brain damage and neurological disorders in the fetus, mainly due to its ability for crossing through the placental barriers. Increase in oxidative stress, inflammation, and DNA damage is main mechanisms of arsenic-induced neurotoxicity. Therefore, this study aimed to evaluate the neuroprotective effects of melatonin, as a potent anti-oxidant and anti-inflammatory agent against arsenic toxicity in the brains of male offspring rats. Pregnant mother rats were randomly assigned into four groups including group I, as control, group II received 10 mg/kg melatonin, group III received arsenic at 50 mg/kg, and group IV received melatonin and arsenic. After a two-month period, oxidative stress, DNA damage, inflammation and apoptosis were assessed in the male offspring rats. Exposure to arsenic significantly increased the pro-inflammatory and oxidative factors resulting in DNA damage and apoptosis in the brain tissues of offspring rats in comparison to controls (p < 0.05). Exogenous administration of melatonin showed a significant increase in the tissue levels of acetylcholine esterase, decrease in the lactate dehydrogenase and myeloperoxidase, when compared to arsenic group (p < 0.05). Melatonin also overcame the arsenic-induced oxidative stress and suppressed inflammation, DNA damage and apoptosis. Our results suggested that melatonin may be a promising neuro-protective agent and momentous therapy for the treatment of arsenic-toxicity in clinical conditions.

Abstract
Ischemia-reperfusion injury is an organ failure caused by hypoxia and reperfusion, which is closely associated with oxidative stress and inflammation. In this study, we investigated whether nobiletin had protective effects on inflammatory parameters, oxidative damage, iNOS-eNOS expressions, and histopathological structure of renal tissue in rats with renal ischemia-reperfusion injury. For this purpose, 24 rats were divided into 4 groups: group 1 (Control), group 2 (Ischemia-Reperfusion-IR), group 3 (Nobiletin-10 mg/kg p.o.), group 4 (Nobiletin + IR). The study was continued for 7 days. At the end of the study, urea (p < 0.05), creatine (p < 0.05), MDA (p < 0.001), TNF-alpha (p < 0.001), IL-1 beta (p < 0.05), and IL-6 (p < 0.001) levels increased in the IR group; however, a significant decrease occurred in group 4 (Nobiletin + IR) and it reached the control group levels. In the IR group, GSH (p < 0.01) levels, and GSH.Px (p < 0.01) and CAT (p < 0.05) activities decreased whereas they increased significantly in group 4 (Nobiletin + IR) and reached the same levels as the control group. In histopathological analyses, destruction and increased iNOS-eNOS expressions in the IR group showed a significant decrease in group 4 (Nobiletin + IR). As a result, the application of nobiletin has shown that it has protective effects by reducing kidney damage caused by IR injury.

Abstract
Citri Reticulatae Pericarpium (CRP), known as Chenpi (CP) in Chinese, is a medicinal food for health and fitness. In order to find out the characteristic activity chemicals distinguishing various cultivars of CRP and provide a reference for effective development of citrus resources, an “activity fingerprint” of CRP from 21 different cultivars was established based on the evaluation of antitussive and expectorant activities. There were 18 common peaks in the HPLC fingerprint, of which 3 flavonoid glycosides and 14 polymethoxyflavonoids (PMFs) were identified by LC/MS-IT-TOF. Furthermore, five characteristic chemicals were determined and similarity calculation with principal component analysis (PCA) was combined together to compare the similarity and difference among various cultivars. The results showed that some other cultivars were also similar to C. reticulata “Chachi” except for C. reticulata “Tangerina” and C. reticulata “Dahongpao” recorded in Chinese Pharmacopoeia. Most importantly, the peels of C. reticulata “Shiyueju,” C. reticulata “Ponkan,” C. reticulata “Tribute,” and C. reticulata “Bayueju,” traditionally rarely used for medicinal food, were highly similar to that of C. reticulata “Chachi” and rich in bioactive flavonoids, which can be considered the effective medicinal resources of CRP.

Abstract
Sanhua decoction, a famous Chinese herbal formula has been widely used for the treatment of stroke. In our study, a rapid, swift and straightforward analytical method with the help of UHPLC-FT-ICR-MS/MS was successfully developed for the first time to separate and identify the chemical constituents of Sanhua decoction. Chromatography was performed on a Universal XB C18 column (150 mm × 2.1 mm, 1.8 μm) using a mobile phase containing 0.1% formic acid–water (A) and acetonitrile (B). A total of 137 compounds in Sanhua decoction were identified or tentatively characterized. The findings revealed the fact that Sanhua decoction mainly contains flavonoids (in Aurantii fructus immaturus and Rheum palmatum L.), anthraquinones (in Rheum palmatum L.), coumarins (in Notopterygii Rhizoma Et Radix), phenylpropanoid glycosides, alkaloids and lignans (in Magnoliae Officmalis Cortex), which made up the key ingredients existing in Sanhua decoction. This study is hoped to be meaningful for the characterization of components in other traditional Chinese medicines, and lay the foundation for research on the pharmacology of Sanhua decoction. Sanhua decoction, a famous Chinese herbal formula has been widely used for the treatment of stroke.![]()

Abstract
Random-pattern flap necrosis is a serious challenge for plastic surgeons. Nobiletin (NOB) is a polymethoxylated flavonoid extracted from citrus fruits reported to have antioxidant, anti-inflammatory and anti-apoptotic effects. Our experiment evaluated the impact of NOB on the viability of random flaps. Thirty six male "McFarlane flap" rat models were separated into two equal groups: a control group and an experimental group treated with 10 mg/kg of NOB. After 7 days, the range of necrosis was calculated, and a histological analysis was performed on tissue specimens. Immunohistochemical staining, lead oxide-gelatin angiography, and a Laser Doppler perfusion imager were used to assess angiogenesis and measure oxidative stress, as indicated by superoxide dismutase (SOD) activity and malondialdehyde (MDA) levels. The average survival area of flap was greater in the NOB-treated group than that in the control group. The NOB-treated group mitigated oxidative stress via augmented SOD, reduced MDA, and enhanced vascular endothelial growth factor (VEGF) expression. Hematoxylin and eosin staining indicated that NOB increased blood flow and had anti-inflammatory effects. Our findings revealed that NOB improved random skin flap survival.

Abstract
The study aimed to examine the effects of nobiletin on the toxicity model induced with acetaminophen (APAP). For this purpose, 24 adult male rats were equally divided into four groups. The groups were the control group (group 1); dimethyl sulfoxide only, the APAP group (group 2) received a single dose of APAP 1000 mg/kg on the 10th day of experiment; the Nobiletin group (group 3), nobiletin (10 mg/kg) for 10 days; and the APAP + Nobiletin group (group 4), nobiletin (10 mg/kg) for 10 days with a single dose of APAP (1000 mg/kg) administered on the 10th day and the experiment ended after 48 hours. At the end of the study, a significant increase in malondialdehyde, interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) levels and a significant decrease in glutathione levels, glutathione peroxidase activities and nuclear factor erythroid-derived 2-like 2 (Nrf-2) and heme oxygenase-1 (HO-1) expressions were observed with APAP application in liver and kidney tissues. Serum aspartate transaminase (AST), alanine transaminase (ALT), urea, and creatinine levels were also significantly increased in the APAP group. However, nobiletin treatment in group 4 reversed oxidative stress and inflammatory and histopathological signs caused by APAP. It is concluded that nobiletin may be a beneficial substance that confers hepatorenal protection to APAP-induced toxicity via antioxidant and anti-inflammatory mechanisms.

Abstract
Background Jianpi-yangwei (JPYW), a traditional Chinese medicine (TCM), helps to nourish the stomach and spleen and is primarily used to treat functional declines related to aging. This study aimed to explore the antiaging effects and mechanism of JPYW by employing a Caenorhabditis elegans model. Methods Wild-type C. elegans N2 worms were cultured in growth medium with or without JPYW, and lifespan analysis, oxidative and heat stress resistance assays, and other aging-related assays were performed. The effects of JPYW on the levels of superoxide dismutase (SOD) and the expression of specific genes were examined to explore the underlying mechanism of JPYW. Results Compared to control worms, JPYW-treated wild-type worms showed increased survival times under both normal and stress conditions (P < 0.05). JPYW-treated worms also exhibited enhanced reproduction, movement and growth and decreased intestinal lipofuscin accumulation compared to controls (P < 0.05). Furthermore, increased activity of SOD, downregulated expression levels of the proaging gene clk-2 and upregulated expression levels of the antiaging genes daf-16, skn-1, and sir-2.1 were observed in the JPYW group compared to the control group. Conclusion Our findings suggest that JPYW extends the lifespan of C. elegans and exerts antiaging effects by increasing the activity of an antioxidant enzyme (SOD) and by regulating the expression of aging-related genes. This study not only indicates that this Chinese compound exerts antiaging effects by activating and repressing target genes but also provides a proven methodology for studying the biological mechanisms of TCMs.

Abstract
Islets transplantation, as a treatment of type 1 diabetes, faces challenges, including the loss of islets in the process of isolation and pre-transplantation due to cellular stresses-induced apoptosis. Accordingly, the optimization of culture plays a decisive role in the transplantation success. In this study, we evaluated the effect of nobiletin on the cultured human islets. Isolated human islets were treated by different concentrations of nobiletin and cultured for 24 and 72 hours. Then, the islets viability, apoptosis, insulin and C-peptide secretion, and apoptosis markers were evaluated. Also, the production of reactive oxygen species (ROS), hypoxia inducible factor 1 alpha (HIF-1α), and its target genes in the islets were examined. Our findings showed that the islets were encountered with hypoxia and oxidative stress after isolation and during culture. These insults induced apoptosis and reduced viability during culture period. Moreover, the secretion of insulin and C-peptide decreased. Nobiletin treatments significantly improved the islets survival through reduction of HIF-1α and ROS production and suppression of apoptosis, along with increased islets function. Islet protective effect of nobiletin might be related to its anti-oxidant, anti-apoptotic and insulinotropic properties. Hence, in order to achieve viable and functional islets for clinical transplantation, the application of nobiletin during pre-transplantation period is useful.

Abstract
The present study aimed to investigate the function of micro (mi)RNA‑153 against isoflurane‑induced neurotoxicity and its mechanism. In isoflurane‑induced mice, miRNA‑153 expression was downregulated compared with in the control group. Downregulation of miRNA‑153 induced neurocyte apoptosis, reduced cell growth and promoted oxidative stress in an in vitro model. Overexpression of miRNA‑153 reduced oxidative stress, promoted cell growth and inhibited neurocyte apoptosis within an in vitro model. Downregulation of miRNA‑153 suppressed nuclear erythroid‑2 related factor 2 (Nrf2)/antioxidant response element (ARE) signaling pathway, which was induced via the overexpression of miRNA‑153 in vitro. The Nrf2 agonist, dimethyl fumarate (2.5 µM), induced the Nrf2/ARE signaling pathway and reduced oxidative stress to induce neurocyte apoptosis in vitro following treatment with anti‑miRNA‑153. The results of the present study suggested the function of miRNA‑153 against neurotoxicity via Nrf2/ARE‑mediated cytoprotection.

Abstract
Before birth and early in life, the developing brain is particularly sensitive to environmental and pharmacological influences. Increasing experimental evidence suggests that an association exists between exposure to anesthesia during a vulnerable period of brain development and subsequent poor neurodevelopmental outcomes. However, the mechanisms underlying this association are not fully understood. Epigenetics, broadly defined as the regulation of gene expression without alterations of DNA sequence, has become a field of tremendous interest in neuroscience. In recent years, a growing body of literature suggests that anesthesia-induced long-term changes in gene transcription and functional deficits in learning and behavior later in life are mediated via epigenetic modifications. This brief review provides an overview of epigenetic mechanisms and highlights the emerging roles played by epigenetic dysfunctions in the processes of anesthesia-induced neurotoxicity in the developing brain. Epigenetic targeting of DNA methyltransferases and/or histone deacetylases may have some therapeutic value. Epigenetics may lead to the identification of novel markers that contribute toward considerable translational significance in the field of neuroprotection.

Abstract
Objective. In China, the Chinese medicine formula modified zhisou powder (MZP) is commonly used to treat COPD with cold-dryness syndrome (CDSCOPD) to relieve cough and sputum. However, the underlying mechanisms of MZP on treating CDSCOPD remain to be elucidated. Methods. COPD and CDSCOPD rat models were established; MZP was given to CDSCOPD rats in the last 7 days of the 97-day model establishment. Then the rats were subjected to lung function measurement. Pathological changes in lungs were observed through paraffin section and H&E staining. The mRNA and protein levels of AQP1, 4, and 5 and Muc5AC and Muc5B in lung were determined by quantitative RT-PCR and western blotting. NE levels was determined by ELISA. Results. The impaired lung functions were observed in rats exposed to cigarette smoke. Among all parameters evaluating lung functions, only tidal volume demonstrates a further decrease in CDSCOPD when compared with COPD, indicating further impaired pulmonary ventilation functions upon cold-dryness stimulation. The intervention of MZP effectively improved lung functions parameters, prevented the inflammations, and eliminated the increases of AQP4 and 5 and the decrease of Muc5AC in lung. Conclusion. MZP probably improves pulmonary functions in CDSCOPD through inhibiting lung inflammation, increasing expressions of AQPs, and decreasing Muc5AC expression in lung.
