Title: Enhanced IL-1{beta}-induced IL-8 production in cystic fibrosis lung epithelial cells is dependent of both mitogen-activated protein kinases and NF-{kappa}B signaling

Abstract

Transcription nuclear factor-{kappa}B (NF-{kappa}B) is hyperactivated in cystic fibrosis (CF) lung epithelial cells, and participates in exaggerated IL-8 production in the CF lung. We recently found that rapid activation of NF-{kappa}B occurred in a CF lung epithelial IB3-1 cell line (CF cells) upon IL-1{beta} stimulation, which was not observed in its CFTR-corrected lung epithelial S9 cell line (corrected cells). To test whether other signaling pathways such as that of mitogen-activated protein kinases (MAPKs) could be involved in IL-1{beta}-induced IL-8 production of CF cells, we investigated ERK1/2, JNK, and p38MAP signaling compared to NF-{kappa}B. Within 30 min, exposure to IL-1{beta} caused high activation of NF-{kappa}B, ERK1/2, p38MAP but not JNK in CF cells compared to corrected cells. Treatment of IL-1{beta}-stimulated CF cells with a series of chemical inhibitors of NF-{kappa}B, ERK1/2, and p38MAP, when used separately, reduced slightly IL-8 production. However, when used together, these inhibitors caused a blockade in IL-1{beta}-induced IL-8 production in CF cells. Understanding of the cross-talk between NF-{kappa}B and MAPKs signaling in CF lung epithelial cells may help in developing new therapeutics to reduce lung inflammation in patients with CF.

  • Bacterial neuraminidase, a sialic acid-degrading enzyme, is one of the virulent factors produced in pathogenic bacteria like as other bacterial components. However little is known about whether bacterial neuraminidase can initiate or modify a cellular response, such as cytokine production, in epithelial cells at infection and inflammation. We demonstrate here that bacterial neuraminidase, but not heat-inactivated neuraminidase, up-regulates expression of interleukin-8 (IL-8) mRNA and protein in lung epithelial A549 and NCI-H292 cells. We also show that bacterial neuraminidase significantly up-regulates IL-8 promoter activity as well as nuclear factor-kappaB (NF-{kappa}B) reporter activity. Moreover, inhibition of NF-{kappa}B signaling suppressed IL-8 mRNA expressionmore » induced by bacterial neuraminidase. Taken together, desialylation-induced IL-8 production in lung epithelial cells may play an important role in infection-associated inflammatory events.« less
  • CD40 is a costimulatory molecule linking innate and adaptive immune responses to bacterial stimuli, as well as a critical regulator of functions of other costimulatory molecules. The mechanisms regulating lipopolysaccharide (LPS)-induced CD40 expression have not been adequately characterized in human monocytic cells. In this study we used a human monocytic cell line, THP-1, to investigate the possible mechanisms of CD40 expression following LPS exposure. Exposure to LPS resulted in a dose- and time-dependent increase in CD40 expression. Further studies using immunoblotting and pharmacological inhibitors revealed that mitogen-activated protein kinases (MAPKs) and NF{kappa}B were activated by LPS exposure and involved inmore » LPS-induced CD40 expression. Activation of MAPKs was not responsible for LPS-induced NF{kappa}B activation. TLR4 was expressed on THP-1 cells and pretreatment of cells with a Toll-like receptor 4 (TLR4) neutralizing antibody (HTA125) significantly blunted LPS-induced MAPK and NF{kappa}B activation and ensuing CD40 expression. Additional studies with murine macrophages expressing wild type and mutated TLR4 showed that TLR4 was implicated in LPS-induced ERK and NF{kappa}B activation, and CD40 expression. Moreover, blockage of MAPK and NF{kappa}B activation inhibited LPS-induced TLR4 expression. In summary, LPS-induced CD40 expression in monocytic cells involves MAPKs and NF{kappa}B.« less
  • Polychlorinated biphenyls (PCBs) are ubiquitous, persistent environmental contaminants that affect a number of cellular systems, including neutrophils. Among the effects caused by the noncoplanar PCB 2,2',4,4'-tetrachlorobiphenyl (2244-TCB) in granulocytic HL-60 cells are increases in superoxide anion production, activation of phospholipase A{sub 2} with subsequent release of arachidonic acid (AA) and upregulation of the inflammatory gene cyclooxygenase-2 (COX-2). The objective of this study was to determine the signal transduction pathways involved in the upregulation of COX-2 by 2244-TCB. Treatment of HL-60 cells with 2244-TCB led to increased expression of COX-2 mRNA. This increase was prevented by the transcriptional inhibitor actinomycin Dmore » in cells pretreated with 2244-TCB for 10 min. The increase in COX-2 mRNA was associated with release of {sup 3}H-AA, phosphorylation of p38 and extracellular signal-regulated kinase (ERK) mitogen-activated protein (MAP) kinases, increased levels of nuclear NF-{kappa}B and increased superoxide anion production. Bromoenol lactone, an inhibitor of the calcium-independent phospholipase A{sub 2}, reduced {sup 3}H-AA release but had no effect on COX-2 mRNA, protein or activity. Pretreatment with SB-202190 or SB-203580, inhibitors of the p38 MAP kinase pathway, prevented the 2244-TCB-mediated induction of COX-2 and phosphorylation of p38 and ERK MAP kinases. These inhibitors did not alter {sup 3}H-AA release. Treatment with PD 98059 or U 0126, inhibitors of the MAP/ERK (MEK) pathway, prevented the 2244-TCB-mediated activation of ERK but had no effect on COX-2 induction or p38 phosphorylation. 2244-TCB treatment did not affect c-Jun N-terminal kinase (JNK) phosphorylation. 2244-TCB exposure increased the amount of nuclear NF-{kappa}B. This increase was prevented by pretreatment with p38 MAP kinase inhibitors, but not by pretreatment with MEK inhibitors. Pretreatment with inhibitors of NF-{kappa}B prevented the 2244-TCB-mediated induction of COX-2 mRNA. 2244-TCB-mediated increases in superoxide anion were prevented by the NADPH oxidase inhibitor apocynin or the free radical scavenger 4-hydroxy TEMPO, but neither of these inhibitors affected the 2244-TCB-induced changes in COX-2 mRNA levels or {sup 3}H-AA release. Taken together these data suggest that p38 MAP kinase-dependent activation of NF-{kappa}B is critical for the 2244-TCB-mediated upregulation of COX-2 mRNA.« less
  • Cytosolic phospholipase A{sub 2} (cPLA{sub 2}) plays a pivotal role in mediating agonist-induced arachidonic acid release for prostaglandin (PG) synthesis during stimulation with interleukin-1{beta} (IL-1{beta}). However, the mechanisms underlying IL-1{beta}-induced cPLA{sub 2} expression and PGE{sub 2} synthesis by canine tracheal smooth muscle cells (CTSMCs) have not been defined. IL-1{beta} induced cPLA{sub 2} protein and mRNA expression, PGE{sub 2} production, and phosphorylation of p42/p44 MAPK, p38 MAPK (ATF{sub 2}), and JNK (c-Jun) in a time- and concentration-dependent manner, determined by Western blotting, RT-PCR, and ELISA, which was attenuated by the inhibitors of MEK1/2 (U0126), p38 MAPK (SB202190), and JNK (SP600125), ormore » transfection with dominant negative mutants of MEK1/2, p38, and JNK, respectively. Furthermore, IL-1{beta}-induced cPLA{sub 2} expression and PGE{sub 2} synthesis was inhibited by a selective NF-{kappa}B inhibitor (helenalin) or transfection with dominant negative mutants of NF-{kappa}B inducing kinase (NIK), I{kappa}B kinase (IKK)-{alpha}, and IKK-{beta}. Consistently, IL-1{beta} stimulated both I{kappa}B-{alpha} degradation and NF-{kappa}B translocation into nucleus in these cells. NF-{kappa}B translocation was blocked by helenalin, but not by U0126, SB202190, and SP600125. MAPKs together with NF-{kappa}B-activated p300 recruited to cPLA{sub 2} promoter thus facilitating the binding of NF-{kappa}B to cPLA{sub 2} promoter region and expression of cPLA{sub 2} mRNA. IL-1{beta}-induced cPLA{sub 2} expression and PGE{sub 2} production was inhibited by actinomycin D and cycloheximide, indicating the involvement of transcriptional and translational events in these responses. These results suggest that in CTSMCs, IL-1{beta}-induced cPLA{sub 2} expression and PGE{sub 2} synthesis was independently mediated through activation of MAPKs and NF-{kappa}B pathways and was connected to p300 recruitment and activation.« less
  • p38 MAPK and nuclear factor-B (NF-B) signaling pathways play an indispensable role in the control of skeletal myogenesis. The specific contribution of these signaling pathways to the response of myoblast to the mechanical stimulation and the molecular mechanisms underlying this response remain unresolved. Using an established in vitro model, we now show that p38 MAP kinase activity regulates the transcriptional activation of NF-{kappa}B in response to mechanical stimulation of myoblasts. Furthermore, SB203580 blocked stretch-induced NF-{kappa}B activation during myogenesis, not through down-regulation of degradation of I{kappa}B-{alpha}, and consequent translocation of the p65 subunit of NF-{kappa}B to the nucleus. It is likelymore » that stretch-induced NF-{kappa}B activation by phosphorylation of p65 NF-{kappa}B. Moreover, depletion of p38{alpha} using siRNA significantly reduces stretch-induced phosphorylation of RelA and NF-{kappa}B activity. These results provides the first evidence of a cross-talk between p38 MAPK and NF-{kappa}B signaling pathways during stretch-induced myogenesis, with phosphorylation of RelA being one of the effectors of this promyogenic mechanism. The {alpha} isoform of p38MAP kinase regulates the transcriptional activation of NF-{kappa}B following stimulation with cyclic stretch.« less
