Sentenece the gene occurs

27899899Moreover, in the first passages, MSCs were capable to release IL1beta, IL6, and IL8, as well as to produce active MMPs allowing them to migrate
27812125Genes-toll-interacting protein (TOLLIP), mitogen-activated protein kinase 9 (MAPK9), interleukin-1beta (IL-1beta), interleukin-8 (IL-8), and chemokine (C-X-C motif) ligand 1 (CXCL1)-related to these two pathways were validated using western blotting
27329245In a study of SASP markers, the expressions of IL6 and IL8 were also more upregulated in human non-pathological prostatic glands after ADT than in untreated specimens
27329245IL6, IL8, and MMP2 were expressed more strongly in human prostate cancer specimens resected after ADT than in untreated tumors
27311854Although gemcitabine also enhanced CXCL8 expression, anti-CXCL8 antibody failed to reduce gemcitabine-induced increases in SA beta-Gal-positive cell numbers
27311854These observations would indicate that cell senescence can proceed independently of CXCL8 expression, a characteristic feature of senescence-associated secretion phenotype
27115165Expressions of IL-6 and IL-8 in RPE/choroid were analyzed using RT-PCR
27115165Expressions of proinflammatory IL-6 and IL-8 were significantly upregulated in RPE/choroid of aged SAMP8 mice
27106773To evaluate the expression of markers correlated with cellular senescence and DNA damage (8-hydroxy-2'-deoxy-guanosine (8-OHdG), p53, p21, APE1/Ref-1 (APE1), interleukin (IL-6 and IL-8) in placentas from healthy and pathologic pregnancies
27106773In placentas of cases affected by PE, HELLP, or IUGR, there was an increased expression of 8-OHdG, p53, APE1, and IL-6 compared to controls (only IL-8 was significantly decreased in cases)
27106773Placentas from pathological pregnancies had an altered expression of 8-OHdG, p53, p21, APE1, IL-6, and IL-8
26654980Senescent cells upregulated the proinflammatory cytokines IL-6 and IL-8, the main markers of the senescence-associated secretory phenotype (SASP)
26506233Down-regulation of COX5B in breast cancer cell lines can suppress cell proliferation and induced cell senescence which was accompanied by elevating production of IL-8 and other cytokines
26506233Cytokines such as IL-8 secreted by senescent cells may in turn alter the microenvironment which could enhance cell migration
26506233These findings may provide a novel paradigm for the treatment which combined anti-cancer drugs with particular cytokine inhibitors such as IL-8 blockers
26433963In this report we show that senescent human peritoneal mesothelial cells (HPMCs) alter the secretory profile of ovarian cancer cells (A2780, OVCAR-3, SKOV-3) by increasing the release of four angiogenic agents: CXCL1, CXCL8, HGF, and VEGF
26397719In vitro treatment of primary human amnion epithelial cells with 40 muM T-oligos ([TTAGGG]2) that mimic telomere fragments, activated p38MAPK, produced senescence-associated (SA) beta-gal staining and increased interleukin (IL)-6 and IL-8 production compared to cells treated with complementary DNA sequences (Cont-oligos, [AATCCC]2)
26284488The search for mediators of senescent HPMC activity showed that increased SW480 cell proliferation was stimulated by IL-6, migration by CXCL8 and CCL2, invasion by IL-6, MMP-3 and uPA, and epithelial-mesenchymal transition by TGF-beta1
25921542Microarray analysis identified differentially regulated genes in response to LPC, which included the components of senescence-associated secretory phenotype (SASP) including interleukin-8 (IL-8), IL-6, transforming growth factor-beta and plasminogen activator inhibitor-1
25635860The mRNAs and proteins of SASP components, such as IL-6 and IL-8, quickly accumulated in SIRT1-depleted cells, and the levels of these factors were also higher than those in control cells, indicating that SIRT1 negatively regulated the expression of SASP factors at the transcriptional level
25635860SIRT1 bound to the promoter regions of IL-8 and IL-6, but dissociated from them during cellular senescence
25635860The acetylation of Histone H3 (K9) and H4 (K16) of the IL-8 and IL-6 promoter regions gradually increased during cellular senescence
25635535Silencing Arg-II or p38alpha in senescent cells recouples eNOS and inhibits IL-6 and IL-8 secretion
25574956Markers of T-cell activation and senescence were determined by flow cytometry, and plasma levels of interleukin-6, interleukin-8, and C-reactive protein (CRP) were measured, as was telomere length of peripheral blood mononuclear cells (PBMC)
25572145Another observation in the present study is the significant up-regulation of key senescence messaging factors regulated by NF-kappaB namely interleukin (IL)-6, IL-8, high-mobility group protein A (HMGA)1 and B (HMGB)1 in E2-transfected cells treated with TNF-alpha
25548483The hepatocyte SASP included characteristic factors such as interleukin (IL)-8 and IL-6, as well as novel components such as SAA4, IL-32 and Fibrinogen, which were validated by qPCR and/or chemokine protein array
25412309Moreover, we demonstrate that PKCeta creates a positive loop for reinforcing senescence by increasing the transcription of both IL-6 and IL-6 receptor, whereas the expression of IL-8 is specifically suppressed by PKCeta
25385658In addition, Abeta(1-42) upregulated interleukin (IL)-6 and IL-8 gene expression in the RPE-choroid
25257149Emphasis was on the influence of egg-oil on cell migration and IL-8 production in HaCaT cells, respiration, mitochondrial membrane potential, reactive oxygen (ROS) production and proliferation in HUVEC and HaCaT cells, cytokine and interleukin production in PBML and UV-light induced damage of FTSM
25220188Six genes independently correlated with either age (IL-6, TNFRSF-11B, IGFBP-3, SAA4, and COPG), prognosis (IL-6, SAA4), or the grade of the glioma (IL-6, IL-8, ICAM-1, IGFBP-3, and COPG)
25196711Molecule activity was assessed on reactive oxygen species (ROS) production, on superoxide dismutase (SOD) and catalase activities and, finally, on inflammatory factor production IL-6, IL-8 and IL-1beta
25093008Large subpopulations of tumor cells expressed the RBL2 pocket protein and senescence associated heterochromatin 1gamma and IL8 receptor beta
25046437Interleukin-6 (IL-6) and IL-8 (protein and mRNA) were both increased compared with NHCs and H69s (all P<0
24828530PKD1 is activated by oncogenic Ras expression and PKD1 promotes Ras OIS by mediating inflammatory cytokines interleukin-6 (IL-6) and interleukin-8 (IL-8) via modulation of NF-kappaB activity
24337384We identified a conserved TNFR-associated factor 6 (TRAF6) binding motif, which was required for CD158d-induced NF-kappaB activation and IL-8 secretion, TRAF6 association with CD158d, and TRAF6 recruitment to CD158d(+) endosomes in transfected cells
23873025Melanoma cells facilitate endothelial gap formation, the first step during tumor transendothelial migration, which is mediated by both adhesion and endogenously produced chemokines (in particular, interleukin-8 (IL-8))
23873025Taken together, these studies provide a rationale for using drug therapies that restore CD82 expression and inhibit IL-8 production to inhibit late-stage melanoma cell extravasation and subsequent metastasis development
23781024Senescent cells secrete various growth factors and cytokines, such as IL6 and IL8, which collectively constitute the senescence-associated secretory phenotype (SASP)
23781024RNAi-mediated knockdown of IkappaBzeta impaired IL6 and IL8 expression, whereas transgenic IkappaBzeta expression resulted in enhanced SASP cytokine expression
23597430Interleukin-8 (IL-8) has been shown to play an important role in tumor growth, angiogenesis, and metastasis, and has close relationship with oxidative stress
23597430The objective of this study was to determine if IL-8 might be able to prevent oxidative stress-induced senescence of endothelial cells and the mechanisms
23597430Human umbilical vein endothelial cells (HUVECs) were cultured and stimulated with hydrogen peroxide in the absence or presence of IL-8
23597430IL-8 dose-dependently inhibited the onset of HUVEC senescence
23597430IL-8 also increased telomerase activity which was accompanied with upregulation of the catalytic subunit, telomerase reverse transcriptase (TERT), whereas these effects were significantly attenuated by SB 225002 (selective non-peptide CXCR2 antagonist)
23597430In conclusion, IL-8 exerted protective effects against endothelial senescence, which may be related to the activation of telomerase
23557734Expressions of IL-8 and MMPs were analyzed by RT-PCR, ELISA, and gelatin zymography
23557734RESULTS: Abeta promotes RPE cells to enter senescence and secrete higher concentrations of IL-8 and MMP-9
23557734Secretion of MMP-9 is associated with compromised barrier integrity and with processing of IL-8 to a more activated form
23385065Cellular senescence, a permanent state of cell cycle arrest that provides a barrier against tumorigenesis, is accompanied by elevated proinflammatory cytokines such as IL1, IL6, IL8 and TNFalpha
23117626NF90 elicited these effects mainly by repressing the translation of target SASP mRNAs, since silencing NF90 did not increase the steady-state levels of SASP mRNAs but elevated key SASP factors including MCP-1, GROa, IL-6, and IL-8
22904099Compared with young EC, senescent cells displayed increased expression of senescence-associated beta-galactosidase, nitric oxide synthase (eNOS), and AKT kinase, and secreted increased amounts of growth factors (VEGF, TGF-beta), cytokines (IL-6, IL-8, MCP-1), adhesion molecules (sICAM-1), and matrix proteins (fibronectin)
22789011Furthermore, hPTTG1 overexpression activated NF-kappaB signaling to transactivate the expression of interleukin (IL)-8 and growth-regulated oncogene alpha (GROalpha) to execute CXCR2 signaling in MCF-7 cells
22374671We found that STAT3 was required for the events leading to senescence, including the initial early-phase ROS increase and the induction of IL1alpha/beta, IL6 and CXCL8 mRNAs 4-5 d after IL6/sIL6R stimulation, suggesting that STAT3's role is indirect
22319624Both fatty acids appeared to abolish H(2)O(2) mediated stimulation of nuclear factor kappaB and IL-6, but not IL-1alpha and IL-8
21980054Secretion of IL-8, a hallmark of senescence-associated secretary phenotype, was measured by ELISA
21980054CKB inhibition alone induced cell senescence, and further enhanced CSE-induced cell senescence and IL-8 secretion
21336305We demonstrate that retinoic-acid-inducible gene-I (RIG-I) is induced through the ataxia telangiectasia mutated-interferon regulatory factor 1 (ATM-IRF1) axis in senescent cells and that RIG-I signalling mediates the expression of two important mediators of inflammation, interleukin-6 (IL-6) and IL-8
21336305We show here that the intracellular, but not the secreted, form of klotho interacts with RIG-I and that this interaction inhibits RIG-I-induced expression of IL-6 and IL-8 both in vitro and in vivo
21084274Many of these induced mRNA changes are in secreted proteins, IL-6, IL-8, and IL-11 and chemokines CXCL2 and CXCL5, or genes associated with an "inflammatory" phenotype
20937593Chromatin immunoprecipitation assay on DNA isolated from IKKbeta immunoprecipitated samples showed PCR amplification of interleukin-8 promoter sequences, a binding site of NFkappaB, indicating an interaction between IKKbeta and NFkappaB
20647331In 22Rv1 human prostate cells, but not in Du145 or RWPE-2, PIM1 overexpression was associated with marked increases in cellular senescence, as shown by changes in the levels of beta-galactosidase (SA-beta-Gal), p21, interleukin (IL)-6 and IL-8 mRNA and protein
20509141Knockdown of integrin beta4 could attenuate HUVEC senescent features, including increased interleukin-8 (IL-8) release and decreased endothelial nitric oxide synthase (eNOS) and NO levels and mitochondrial membrane potential in vitro
20053980Protein levels of IRAK1 and PAI-1 were analyzed by Western blot and those of IL6 and IL8 by ELISA
20016134RESULTS: Senescent A549 cells and HDMECs, whether stimulated with lipopolysaccharide or not, produced greater amounts of IL-6, IL-8 and TNF-alpha, which paralleled NF-kappaB activation, than did presenescent cells
19935801In addition, these cells secrete higher levels of IL-6 and IL-8 representing key components of the senescence-associated secretory phenotype (SASP) with the ability to impact on neighbouring cells
19805069We show that cell surface-bound IL-1alpha is essential for signaling the senescence-associated secretion of IL-6 and IL-8, 2 proinflammatory cytokines that also reinforce the senescence growth arrest
19650831This characteristic phenotype included persistently activated DNA damage signalling (detected as 53BP1/gammaH2AX(+) foci), enhanced senescence-associated beta-galactosidase activity, expansion of promyelocytic leukaemia nuclear compartments and induced expression of several cytokines (especially interleukins IL-6, IL-8 and IL-24), overall features shared by cells undergoing replicative or premature cellular senescence
19584087We have identified a significantly altered cellular phenotype in response to chronic hypoxia as characterized by increased receptor-mediated apoptotic resistance, the induction of cellular senescence, increased invasion and the increased secretion of IL-1 beta, IL6, IL8 and TNFalpha cytokines
19484468This analysis was used to compare cells from young and old populations, and after perturbing normal conditions, with changes in temperature, adenosine triphosphate (ATP) concentration (using NaF, an inhibitor of glycolysis, and alpha-toxin, a pore-forming molecule used to permeabilize red cells to ATP), and water transport rates [using glycerol, and p-chloromercuriphenylsulfonic acid (pCMBS) to inhibit aquaporins, AQPs]
19407340Herein, we show that lithium induces a rapid and pronounced up-regulation of the matrix metalloproteinase (MMP)-1, an inflammation and senescent cell marker, at the mRNA and protein levels, whereas the induction of two other senescent cell markers is either weak (interleukin-8) or delayed (plasminogen activator inhibitor-1)
19325234IL-6 and IL-8, two well-known proinflammatory cytokines, seem to play a central role in premature cellular senescence induction
19298284The neutrophil chemoattractant interleukin (IL)-8 was low while the constitutive production of monocyte chemoattractant protein (MCP)-1 was highly elevated in medium from cultured CRL-7815 fibroblasts
19053174In cultured premalignant epithelial cells, SASPs induced an epithelial-mesenchyme transition and invasiveness, hallmarks of malignancy, by a paracrine mechanism that depended largely on the SASP factors interleukin (IL)-6 and IL-8
19027816Resveratrol treatment effectively prevented increased production of intracellular reactive oxygen species (iROS) and inflammatory markers (IL1alpha, IL6, IL8, and ELAM-1), and reduced expression of the senescence markers sa-beta-gal, lipofuscin, and accumulation of carbonylated proteins
18842679In this study, we compared the biological behavior of CAFs that were isolated from a prostate tumor to their normal-associated fibroblast (NAF) counterparts
18838863While some of these factors have been previously shown to possess different pro-tumorigenic activities, we recently demonstrated that the secretion of CXCR2-binding chemokines (such as IL-8 or GROalpha) by senescent cells contribute to reinforce senescence via activation of the p53 pathway
18555778Furthermore, we demonstrate that the transcription factor C/EBPbeta cooperates with IL-6 to amplify the activation of the inflammatory network, including IL-8
18555778In human colon adenomas, IL-8 specifically colocalized with arrested, p16(INK4A)-positive epithelium
18313665TRAIL-stimulated production of several cytokines, IL-8, RANTES, MCP-1 and bFGF, and activation of caspases 1 and 8 was essential for this effect
18313665Antibodies to IL-8, RANTES, and bFGF blocked TRAIL-induced cell proliferation and further stimulated apoptosis
17955335DARC binds ELR + angiogenic chemokines such as IL-8 (CXCL8)
17955335Moreover, addition of excess IL-8 during incubation had the similar effect
16626901In particular, a significant upregulation of interleukin-8, VEGI, and the IGF-binding proteins 3 and 5 was observed
16626901In the case of interleukin-8, a roughly 50-fold upregulation of the protein was also found in cellular supernatants
16626901The extracellular proteins encoded by these genes are well known for their ability to modulate the apoptotic response of human cells, and in the case of interleukin-8, clear links to the establishment of atherosclerotic lesions have been defined
16444871Exogenous ADMA also stimulated secretion of monocyte chemotactic protein-1 and interleukin-8
16161253We have previously reported that sodium fluoride (NaF) showed slightly higher cytotoxicity against human oral tumor cell lines than normal human oral cells
16161253Possible changes in the NaF sensitivity of three normal human oral cell types (gingival fibroblast HGF, pulp cell HPC, periodontal ligament fibroblast HPLF) during in vitro ageing were investigated in the present study
16161253NaF dose-dependently reduced the viable cell number, but did not show any beneficial (growth promoting) effect (so-called "hormesis") at lower concentrations
16161253NaF produced large DNA fragments, without induction of internucleosomal DNA fragmentation, possibly due to weak activation of caspases -3, -8 and -9
16161253Higher concentrations of NaF were required to reduce the number of viable senescent cells than younger cells, indicating that cells become resistant to cytotoxicity of NaF with in vitro ageing
15308550Exogenous ADMA also stimulated secretion of MCP-1 and interleukin-8
10811143The cAMP enhancers, caffeine, NaF, and forskolin significantly increased the thymulin-stimulated release of gonadotropins
9892847The cAMP enhancers, caffeine, NaF and forskolin significantly increased the thymulin-stimulated release of GH while trifluoperazine, a protein kinase C inhibitor, had no effect
9818729The cAMP enhancers, caffeine, NaF and forskolin, significantly increased the thymulin-stimulated release of PRL and TSH, while trifluoperazine, a protein kinase C inhibitor, had no effect
9680181The activation of NF-kappaB has been recognized to regulate a number of genes necessary for normal T cell responses including IL-2, IL-6, IL-8, and several T cell surface receptors
7737374On exposure to TNF, senescent HDF produced IL-6 and IL-8, but to a much lower degree than that produced by young HDF
