Abstract
ims: The aim of this study was to evaluate the combined and comparative efficacy of Caffeic acid phenethyl ester (CAPE) and curcumin in breast cancer. BACKGROUND CAPE and curcumin are a class of phenolics. While curcumin is obtained from turmeric, CAPE is found in Baccharis sarothroides and Populus deltoides. Both agents are reported to produce activities in some cancer types. The combined and comparative effects of the two agents in breast cancer have not yet reported. OBJECTIVE We evaluated the potential of CAPE and curcumin in both in vitro and in vivo breast cancer models. METHODS Human breast cancer cell lines, MDA-MB-231 and MCF-7, were exposed to CAPE and curcumin, followed by functional assays such as cell cytotoxicity, cell proliferation and colony formation, cell cycle, mitochondrial membrane potential, apoptosis, and monodansylcadaverine (MDC) staining for autophagy. Computational analyses and mouse models were also used. RESULTS Employing computational analyses, both agents were found to exhibit drug-like properties. Both molecules interacted with the key molecules of the NF-κB pathway. CAPE and curcumin inhibited cell proliferation, colony formation, and invasion, triggering apoptosis in breast cancer cells. CAPE was found to be more effective than curcumin. Two agents working together were more effective than each agent working alone. Both agents suppressed the expression of survivin, Bcl-xL and GLUT-1. The level of cleaved PARP was increased by both agents. Both phenolics observed an induction in ROS generation. Further, both molecules triggered a dissipation in mitochondrial membrane potential. In mice models implanted with Ehrlich-Lettre ascites carcinoma (EAC) cells, both drugs inhibited the growth of the tumour. The phenolics also modulated the metabolic parameters in tumour-bearing mice. CONCLUSION The observations suggest that the combination of curcumin plus CAPE may be better in comparison to individual molecules. Other: The study opens a window for analysing the efficacy of the combination of CAPE and curcumin in animal studies. This will provide a basis for examining the combined efficacy of two agents in a clinical trial.

Abstract
Alzheimer's disease (AD) is an age-dependent neurodegenerative disorder and the leading cause of dementia. AD is characterized by the aggregation of amyloid-ß (Aß) peptide, increased levels of tau protein, and loss of redox homeostasis responsible for mitochondrial dysfunction, oxidative stress, and neuroinflammation. Excessive accumulation of toxic Aß plaques activates microglia, which initiates neuroinflammation and consequently accelerates synaptic damage and neuronal loss. Various proinflammatory cytokines release, microglia proliferation, reactive astrocyte, and oxidative (reactive oxygen species (ROS) production, level of antioxidant enzymes, redox homeostasis, and lipid peroxidation) stress play a major role in AD. Several studies revealed that nuclear factor erythroid 2-related factor 2 (Nrf2) regulates redox homeostasis and works as an anti-inflammatory in various neurodegenerative disorders. D-Glutamate expression of transcription factor Nrf2 and its genes (glutamate-cysteine ligase catalytic subunit (GCLC), Heme oxygenase-1 (HO-1), and NADPH quinone oxidoreductase I (NQO1)) has been found in AD. Nrf2-HO-1 enhances the expression of antioxidant genes, inhibits microglia-mediated inflammation, and boosts mitochondrial function, suggesting that modulators of this protein may be useful to manage AD. This review focuses on the role of Nrf2 in AD, with a particular emphasis on the various pathways involved in the positive and negative modulation of Nrf2, namely Phosphoinositide 3-kinase (PI3K), Glycogen synthase kinase-3 (GSK-3), Nuclear factor kappa-B (NF-κB), and p38Mitogen-activated protein kinases (p38MAPK). Also, we have discussed the progress and challenges regarding the Nrf2 activators for AD treatment.

Abstract
Vascular endothelium dysfunction caused by endothelium inflammation is a trigger of numerous cardiovascular diseases. Vascular endothelium inflammation often occurs in patients with obesity. Asprosin (ASP) derived from white adipose tissue plays important roles in maintaining glucose homeostasis. However, effect of ASP on the vascular endothelium inflammation induced by hyperlipidemia and its underlying mechanism remains largely unclear. In this study, models of vascular endothelium inflammation were established to investigate the effect of ASP on the endothelium inflammation both in vivo and in vitro. Our data in vivo showed that recombinant ASP or high-fat diet (HFD) significantly increased the circulating levels of IL-6 and TNF-α and enhanced the adhesion of macrophages to endothelia characterized by the expression increase of CD68, ICAM-1, and VCAM-1 in rats. However, neutralization of ASP with an ASP specific antibody (AASP) significantly antagonized the changes induced by HFD. Similarly, our data in vitro also showed that ASP treatment elevated the expressions of IL-6, TNF-α, and ICAM-1 as well as VCAM-1. More important, our data revealed that the pro-inflammation effect of ASP was achieved by activating the IKKβ-NF-κBp65 pathway other than the oxidative stress pathway both in vivo and in vitro. In conclusion, our results demonstrate that ASP is a pro-inflammation player in the obesity-associated endothelium dysfunction. The findings would provide a novel target for the prevention and treatment of obesity-related cardiovascular diseases.

Abstract
The sustained activation of the nuclear factor κB (NF-κB) signaling pathway has been observed in human inflammatory bowel disease (IBD). Ophiopogonin D (OP-D) is a small molecular compound isolated from Ophiopogon japonicus, a widely used herbal remedy. In this study, dextran sodium sulfate was used to make a mouse model of experimental colitis and verify the effect of OP-D on the mouse model of experimental colitis. Small molecule-protein molecular docking approaches were also used to discover the mechanisms underlying the OP-D-induced regulation of colitis. In colitis, the OP-D can inhibit the apoptosis of intestinal mucosa cells, restore the intestinal barrier, and alleviate inflammation. The molecular docking simulations showed that OP-D had a high affinity with the REL-homology domain of NF-κB-p65 that affected its translocation to the nucleus. In a cell study, the effects of OP-D on inflammation and barrier dysfunction were significantly decreased by a small interfering RNA targeting NF-κB-p65. Further, the LPS-induced increase in NF-κB-p65 in the nucleus was also significantly inhibited by OP-D. OP-D alleviated experimental colitis by inhibiting NF-κB. New insights into the pathogenesis and treatment options of colitis are provided through this study.

Abstract
Neonatal sepsis (NS) is a severe syndrome in newborns that is induced by infections, and the initiation and development of NS are closely associated with the function of miRs. In the current study, the effects of berberine, which is a functional component in traditional Chinese medicine (TCM), against NS were assessed by focusing on the interaction of berberine with miR-132-3p-mediated signaling. An NS model was induced using cecal slurry (CS) in vivo and LPS in vitro, and berberine treatment was applies. The changes in survival rate, intestinal structure, and systemic inflammation in mice and the viability, apoptosis, and inflammatory response in intestinal cells were measured. At the molecular level, miR-132-3p levels and the activities of the FOXA1 and NF-κB pathways were analyzed. The data showed that berberine increased the survival rates of CS-induced mice. The intestinal injuries induced by CS were also attenuated by berberine, which was associated with inhibition of the production of systemic IL-6, IL-1β, and TNF-α. At the molecular level, the expression of miR-132-3p was upregulated, suppressing the expression of FOXA1, p-IκBα, and p65 while inducing the expression of IκBα. The effects of berberine on NS-induced impairments were blocked by the injection of the miR-132-3p antagomir, which exacerbated intestinal injuries, induced systemic inflammation, and reactivated the FOXA1 and NF-κB pathways. The findings in the in vivo model were validated with in vitro assays. Collectively, the findings outlined in the current study indicated that berberine had solid protective effects against NS-induced symptoms in newborn mice, and the effects depended on the upregulation of miR-132-3p.

Abstract
Intervertebral disc (IVD) degeneration is a major cause of low back pain associated with several pathological changes in the IVD, including dysfunction of nucleus pulposus (NP) cells. Ganoderic Acid A (GAA), one of triterpenoid extracts of Ganoderma lucidum (G. lucidum), has been reported to possess anti-inflammatory effect. In the current study, we aimed to evaluate the effect of Ganoderic Acid A (GAA) on the interleukin-1β (IL-1β)-induced inflammation in human NP cells. Our results showed that the IL-1β-stimulated production of inflammatory mediators including nitric oxide (NO), prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were suppressed by GAA. In addition, treatment of NP cells with GAA significantly inhibited the production of inflammatory cytokines tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in IL-1β-stimulated human NP cells. GAA improved the reduced expression levels of extracellular matrix (ECM) proteins, collagen II and aggrecan in IL-1β-stimulated human NP cells. GAA also alleviated IL-1β-induced the levels of matrix metalloproteinase (MMP)-3 and MMP-13. Furthermore, GAA inhibited the IL-1β-induced upregulation of the phosphorylation of p65 and downregulation of IκBα. Taken together, these findings indicated that GAA alleviated IL-1β-induced inflammation and ECM degradation in NP cells through regulating NF-κB pathway.

Abstract
Proinflammatory mediators such as interleukin (IL)-1β cause retinal pigment epithelium (RPE) inflammation, which is related to visual deterioration, including age-related macular degeneration and diabetic retinopathy. Oleuropein is a polyphenol compound that shows potent anti-inflammatory, antioxidant, and anti-cancer activities, but its effects on IL-1β-induced inflammation have not been examined in the adult RPE cell line ARPE-19. Here, we assessed the ability of oleuropein to attenuate this inflammation in ARPE-19 cells. IL-1β induced secretion of the inflammatory cytokines IL-6, monocyte chemoattractant protein-1 (MCP)-1, and soluble intercellular adhesion molecule (sICAM)-1. As measured by enzyme-linked immunosorbent assay, oleuropein significantly inhibited levels of all three proteins and led to decreased monocyte adhesiveness to ARPE-19 cells. To clarify the underlying anti-inflammatory mechanisms, we used western blots to evaluate the effect of oleuropein on inactivation of the nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways. The results showed that oleuropein significantly decreased levels of the inflammatory mediator cyclooxygenase-2 and increased anti-inflammatory protein HO-1 expression. We next examined if the anti-inflammatory activity of oleuropein arises via inactivated NF-κB. We found that suppressing phosphorylation of the JNK1/2 and p38 MAPK signaling pathways inhibited IL-6, MCP-1, and sICAM-1 secretion, implicating these pathways and NF-κB suppression in the effects of oleuropein. These results indicate that oleuropein shows potential for the prevention and treatment of inflammatory diseases of the retina.

Abstract
Background/Aim: Pancreatic adenocarcinoma is a highly malignant tumor. Synergistic combinations of anticancer agents for the effective treatment of pancreatic cancer patients are urgently needed. Here, we investigated the combined effect of celecoxib (CEL) and salirasib (SAL) on pancreatic cancer cells. Methods: Cell viability and apoptosis were measured by the trypan blue assay, three-dimensional cultures, propidium iodide staining, and caspase-3 assay. NF-κB activation and the protein levels of Akt, pAkt, and Bcl-2 were determined by the luciferase reporter assay and western blot. Results: Co-treatment with CEL and SAL had stronger effects on decreasing cell viability and inducing apoptosis in Panc-1 cells as compared with each agent individually. This combination strongly inhibited NF-κB activity and reduced pAkt and Bcl-2 levels in Panc-1 cells. Conclusion: SAL in combination with CEL may represent a new approach for effective inhibition of pancreatic cancer.

Abstract
BACKGROUND Cancer-related inflammation is recognized as a driver for tumor progression and chemokines are important players in both inflammation and the progression of many cancer types. CXC chemokines, especially CXCL8, have been implicated in melanoma growth and metastasis, while less is known for their roles in drug resistance. METHODS We generated drug-resistant cells by continuous exposure to chemotherapeutic drugs and analyzed the mechanism(s) of therapy resistance in malignant melanoma. RESULTS We report chemotherapies induced upregulation of a variety of chemokines in the CXCR1/CXCR2 network by an NF-κB-dependent mechanism. Notably, analysis of the drug-resistant melanoma cell line selected after prolonged exposure to chemotherapeutic drug dacarbazine revealed higher levels of CXCL8 and CXCR2 compared with parent cells as a signature of drug resistance. CXCR2 neutralization markedly improved sensitivity to dacarbazine in melanoma cells. CONCLUSION These data provide insights into what drives melanoma cells to survive after chemotherapy treatment, thus pointing to strategies for developing combined drug therapies for combating the problem of chemotherapy resistance in melanoma.

Abstract
Neuroinflammation plays a crucial role in expression of symptoms of numerous autoimmune and neurodegenerative diseases such as pain during rheumatoid arthritis. Overproduction of pro-inflammatory cytokines and activation of intracellular signaling pathways have been strongly implicated in the generation of pathological pain states, particularly at central nervous system sites and induction of spinal neuroinflammatory symptoms. The wide ranges of research to define new therapeutic approaches, including neuroimmune-modulators like stem cells are in progress. Mesenchymal stem cells conditioned medium (MSC-CM) has anti-inflammatory factors which can regulate the immune responses. The aim of this study was to investigate the effect of administration of MSC-CM on behavioral, cellular and molecular aspects of adjuvant-induced arthritis in male Wistar rats. Complete Freund's adjuvant (CFA)-induced arthritis (AA) was caused by single subcutaneous injection of CFA into the rat's hind paw on day 0. MSC-CM was administered daily (i.p.) and during the 21 days of the study after injection. Hyperalgesia, Edema, Serum TNF-α levels and p38MAPK and NF-κB activities were assessed on days 0,7,14 and 21 of the study. The results of this study indicated the role of MSC-CM in reducing inflammatory symptoms, serum TNF-α levels and activity of intracellular signaling pathway factors during different phases of inflammation caused by CFA. It seems that MSC-CM treatment due to its direct effects on inhibition of intracellular signaling pathways and pro-inflammatory cytokines can alleviate inflammatory symptoms and pain during CFA-induced arthritis.

Abstract
Background: 5-fluorouracil (5-FU) is one of the most commonly used first-line anticancer drugs to treat gastric cancer in clinical practice. However, severe adverse events such as gastrointestinal toxicity and bone marrow suppression limit its clinical application. Combination chemotherapy to combine two or more anticancer drugs with different mechanistic action is an effective anticancer strategy against gastric cancer. Therefore, we studied the anticancer effect of the combination of 5-FU with curcumin against gastric cancer MKN45 and AGS cells (normal gastric mucosal GES-1 cells as control) and associated molecular mechanisms. Methods: Cytotoxicity of 5-FU and curcumin alone or in combination was evaluated in MKN45, AGS and GES cells by MTT assay. The protein expressions of COX-2 and NF-κB were evaluated in MKN45 cells by Western blotting analysis. In addition, antitumor activity of 5-FU and curcumin alone or in combination was evaluated in nude mice bearing MKN45 tumor xenografts in vivo. Results: The combination of 5-FU and curcumin (2:1, mol/mol) showed 2.2-, 3.5-fold and 2.3-, 3.9-fold enhanced cytotoxic effect compared to 5-FU or curcumin alone and generated synergistic effect at the concentration of 5-FU (>4.09 and >5.71 μmol/l) and curcumin (>2.05 and > 2.86 μmol/l) in MKN45 cells for 48 h and 72 h exposures, respectively. The combination of 5-FU and curcumin also potentiated cytotoxicity in AGS cells compared to 5-FU or curcumin alone but the effect was moderate. However, the cytotoxicity of 5-FU and curcumin alone or in combination was much less in GES-1 cells. Furthermore, the protein expressions of COX-2 and NF-κB in MKN45 cells were decreased by 44.79% and 37.67%, 47.17% and 48.21%, 60.21% and 62.44%, respectively, after treatment of curcumin (25 μmol/l) and 5-FU (50 μmol/l) alone or in combination for 48 h. Curcumin also enhanced the anticancer activity of 5-FU without increasing toxicity in nude mice bearing MKN45 tumor xenografts in vivo. Conclusions: Curcumin enhances the anticancer effect of 5-FU against gastric cancer in vitro and in vivo. The possible molecular mechanism may be, at least in part, related to down-regulation of COX-2 and NF-κB pathways.

Abstract
Optic nerve crush model could be used to investigate the mechanism of neuronal survival and axonal regeneration in central nervous system. Triptolide, a Chinese herb extract with anti-inflammatory and immunosuppressive activities, has shown neuron protective functions in nervous system. In this study, we investigated the changes in retinal ganglion cell survival and axonal regeneration after administration of triptolide in optic nerve crush model. Triptolide treatment tended to promote retinal ganglion cell survival rather than optic nerve regeneration as well as inhibit the expression of tumor necrosis factor-α and activation of nuclear factor-kappa B. These findings suggested that intraperitoneal injection of triptolide may be an effective treatment for optic nerve injury and this effect was attributed at least in part to its anti-inflammatory actions.

Abstract
Nuphar lutea L. SM., leaf and rhizome extracts (NUP), contain nupharidines as active components. Nupharidines belong to the sesquiterpene lactones class of a naturally occurring plant terpenoids. This family of compounds has gained considerable interest for treating infection, inflammation and cancer. NF-κB is a central, downstream regulator of inflammation, cell proliferation and apoptosis. In our previous work we demonstrated strong inhibition of NF-κB activity and induction of apoptosis by NUP. In addition, NUP exhibited anti-inflammatory properties and partial protection from LPS-induced septic shock by modulating ERK pathway and cytokine secretion in macrophages. In the present study, we examined the effect of NUP in a B16 melanoma experimental murine lung metastasis model and its ability to affect the ERK and NF-κB pathways in variety of cell lines. We showed that NUP and cisplatin combined treatment was synergistic and reduced the lung metastatic load. In addition NUP treatment inhibited TNFα-induced IκBα degradation and NF- κB nuclear translocation. We also observed that NUP induced ERK activation. Furthermore, ERK inhibition prevented NF-κB inactivation by NUP. Overall, our work implies that co-administration of NF-κB inhibitors such as NUP, with standard anti-cancer drugs, may act as "sensitizers" for more effective chemotherapy.

Abstract
Abnormal cytoplasmic mislocalization of transactive response DNA binding protein 43 (TARDBP or TDP-43) in degenerating neurons is a hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with ubiquitin-positive inclusions (FTLD-U). Our previous work suggested that nuclear factor kappa B (NF-κB) may constitute a therapeutic target for TDP-43-mediated disease. Here, we investigated the effects of root extract of Withania somnifera (Ashwagandha), an herbal medicine with anti-inflammatory properties, in transgenic mice expressing a genomic fragment encoding human TDP-43A315T mutant. Ashwagandha extract was administered orally to hTDP-43A315T mice for a period of 8 weeks starting at 64 and 48 weeks of age for males and females, respectively. The treatment of hTDP-43A315T mice ameliorated their motor performance on rotarod test and cognitive function assessed by the passive avoidance test. Microscopy examination of tissue samples revealed that Ashwagandha treatment of hTDP-43A315T mice improved innervation at neuromuscular junctions, attenuated neuroinflammation, and reduced NF-κB activation. Remarkably, Ashwagandha treatment reversed the cytoplasmic mislocalization of hTDP-43 in spinal motor neurons and in brain cortical neurons of hTDP-43A315T mice and it reduced hTDP-43 aggregation. In vitro evidence is presented that the neuronal rescue of TDP-43 mislocalization may be due to the indirect effect of factors released from microglial cells exposed to Ashwagandha. These results suggest that Ashwagandha and its constituents might represent promising therapeutics for TDP-43 proteinopathies.

Abstract
Triterpenoids extracted from Cimicifuga foetida have been reported to inhibit cancer by inducing cell cycle arrest and apoptosis. In this study, KHF16 (24-acetylisodahurinol-3-O-β-D-xylopyranoside), a cycloartane triterpenoid isolated from the rhizomes of C. foetida, showed potent anti-cancer activity in multiple ERα/PR/HER2 triple-negative breast cancer (TNBC) cell lines. KHF16 significantly induces cell cycle G2/M phase arrest and apoptosis in both MDA-MB-468 and SW527 TNBC cell lines. KHF16 reduces the expression levels of XIAP, Mcl-1, Survivin and Cyclin B1/D1 proteins. Importantly, KHF16 inhibits TNFα-induced IKKα/β phosphorylation, IKBα phosphorylation, p65 nuclear translocation and NF-κB downstream target gene expression, including XIAP, Mcl-1 and Survivin, in TNBC cells. These results suggest that KHF16 may inhibit TNBC by blocking the NF-κB signaling pathway in part.

Abstract
Recently, the human ether à go-go (eag) related gene 1 (hERG1) channel, a member of the voltage-dependent potassium channel (Kv) family, was determined to have a critical role in cancer cell proliferation, invasion, tumorigenesis and apoptosis. However, the expression levels and functions of hERG1 in osteosarcoma cells remain poorly characterized. In this study, hERG1 transcript and protein levels in osteosarcoma cells and tissues were measured using semi-quantitative real time PCR (RT-PCR), Western blot, and immunohistochemistry. The effects of hERG1 knockdown on osteosarcoma cell proliferation, apoptosis and invasion were examined using CCK-8, colony formation, flow cytometry, caspase-3 activity, wound healing and transwell based assays. Furthermore, semi-quantitative RT-PCR, Western blot and a luciferase reporter assay were used to assess the effects of hERG1 inhibition on the nuclear factor-κB (NF-κB) pathway. In addition, the effect of NF-κB p65-siRNA and NF-κB p65 expression on the survival of osteosarcoma cells was investigated. Through this work, a relationship for hERG1 with the NF-κB pathway was identified. Osteosarcoma cells and tissues were found to express high levels of hERG1. Knockdown of hERG1 significantly suppressed cellular proliferation and invasion, and induced apoptosis, while inhibition of hERG1 significantly decreased activation of NF-κB. Overall, hERG1 may stimulate nuclear translocation of p65, thus regulating the NF-κB pathway through the activation of the hERG1/beta1 integrin complex and PI3K/AKT signaling. Taken together, these results demonstrate that hERG1 is necessary for regulation of osteosarcoma cellular proliferation, apoptosis and migration. Furthermore, this regulation by hERG1 is, at least in part, through mediation of the NF-κB pathway.

Abstract
ETHNOPHARMACOLOGIC RELEVANCE Persicaria chinensis L. (Polygonaceae) [also synonym as Polygonum chimnense L.] has been used as Chinese traditional medicine to treat ulcer, eczema, stomach ache, and various inflammatory skin diseases. Due to no molecular pharmacological evidence of this anti-inflammatory herbal plant, we investigated the inhibitory mechanisms and target proteins contributing to the anti-inflammatory responses of the plant by using its methanolic extract (Pc-ME). MATERIALS AND METHODS We used lipopolysaccharide (LPS)-treated macrophages and a murine HCl/EtOH-induced gastritis model to evaluate the anti-inflammatory activity of Pc-ME. HPLC analysis was employed to identify potential active components of this extract. Molecular approaches including kinase assays, reporter gene assays, immunoprecipitation analysis, and overexpression of target enzymes were used to confirm target enzymes. RESULTS Pc-ME inhibited LPS-induced nitric oxide and prostaglandin E2 release by RAW264.7 macrophages and ameliorated HCl/EtOH-induced gastric ulcers in mice. The nuclear translocation of NF-κB (p65 and p50) was suppressed by Pc-ME. Phosphorylation of Src and Syk, their kinase activities, and formation of the signaling complex of these proteins were repressed by Pc-ME. Phosphorylation of p85 and Akt induced by Src or Syk overexpression was blocked by Pc-ME. In the mouse gastritis model, orally administered Pc-ME suppressed the increased phosphorylation of IκBα, Αkt, Src, and Syk. Caffeic acid, kaempferol, and quercetin, identified as major anti-inflammatory components of Pc-ME by HPLC, displayed strong nitric oxide inhibitory activity in LPS-treated macrophages. CONCLUSION Pc-ME might play a pivotal ethnopharmacologic role as an anti-inflammatory herbal medicine by targeting Syk and Src kinases and their downstream transcription factor NF-κB.

Abstract
One of the earliest neuropathological events in Alzheimer's disease is accumulation of astrocytes at sites of Aβ1-42 depositions. Our results indicate that Aβ1-42 toxic peptide increases lipid peroxidation, apoptosis and cell death in neurons but not in astrocytes in primary culture. Aβ1-42-induced deleterious neuronal effects are not present when neurons and astrocytes are mixed cultured. Stimulation of astrocytes with toxic Aβ1-42 peptide increased p-65 and decreased IκB resulting in inflammatory process. In astrocytes Aβ1-42 decreases protein expressions of sirtuin 1 (SIRT-1) and peroxisome proliferator-activated receptor γ (PPAR-γ) and over-expresses peroxisome proliferator-activated receptor γ coactivator 1 (PGC-1) and mitochondrial transcription factor A (TFAM), protecting mitochondria against Aβ1-42-induced damage and promoting mitochondrial biogenesis. In summary our data suggest that astrocytes may have a key role in protecting neurons, increasing neural viability and mitochondrial biogenesis, acquiring better oxidative stress protection and perhaps modulating inflammatory processes against Aβ1-42 toxic peptide. This might be a sign of a complex epigenetic process in Alzheimer's disease development.

Abstract
Esophageal adenocarcinoma (EAC) is the most frequent malignancy in the esophagus in the US and its incidence has been rising rapidly in the past few decades. Chronic gastroesophageal reflux disease (GERD), where the esophageal epithelium is abnormally exposed to acid and bile salts, is a pro-inflammatory condition that is the main risk factor for the development of Barrett's esophagus (BE) and its progression to EAC. Glutathione peroxidase 7 (GPX7) is frequently silenced through DNA hypermethylation during Barrett's tumorigenesis. In this study, we investigated the role of GPX7 in regulating the bile salts-induced inflammatory signaling in Barrett's carcinogenesis. Using quantitative real-time PCR (qRT-PCR), we demonstrated a significant induction in the expression levels of pro-inflammatory cytokines (TNF-α, IL-1β, IL-6, and IL-8) and chemokines (CXCL-1 and CXCL-2) in esophageal cells after exposure to acidic (pH4) or neutral (pH7) bile salts. Western blot analysis showed that exposure to acidic and neutral bile salts increased p-NF-κB-p65 (S536) protein levels independent of ROS. Reconstitution of GPX7 expression in EAC cells abolished the increase of p-p65 (S536) protein levels and mRNA expression of cytokines and chemokines upon treatment with acidic and neutral bile salts. Examination of human primary EAC tissues by qRT-PCR demonstrated significant overexpression of cytokines (TNF-α, IL-1β and IL-8) in EAC samples, as compared to normal samples, with significant inverse correlation with GPX7 expression level. Taken together, the loss of GPX7 expression promotes bile salt-induced activation of pro-inflammatory cytokines and chemokines; important contributors to GERD-associated Barrett's carcinogenesis.

Abstract
The A3 adenosine receptor (A3AR) is highly expressed in various human solid tumor cells whereas low expression is found in the adjacent normal tissues. Activation of the A3AR with synthetic highly selective agonists, such as IB-MECA, Cl-IB-MECA or LJ529, induces tumor growth inhibition of melanoma, lymphoma, breast, hepatoma, prostate and colon carcinoma cells both in vitro and in vivo. Two molecular events take place upon receptor activation and include: a. receptor internalization and subsequent degradation, followed by decreased receptor mRNA and protein expression level. b. modulation of down-stream signal transduction pathways, including those related to Wnt and NF-κB. Subsequently, the levels of cyclin D1 and c-Myc are decreased leading to tumor growth inhibition. IB-MECA synergizes with chemotherapeutic agents to yield an additive anti-tumor effect and protects against myelotoxicity induced by chemotherapy. Taken together, A3AR agonists may be suggested as a new family of orally bioavailable compounds to be developed as potent inhibitors of malignant diseases.
