Effect of E. cava and C. indicum Complex Extract on Phorbol 12-Myristate 13-Acetate (PMA)-Stimulated Inflammatory Response in Human Pulmonary Epithelial Cells and Particulate Matter (PM) 2.5-Induced Pulmonary Inflammation in Mice. Pharmaceutics 2023; 15:2621. [PMID: 38004599 PMCID: PMC10674792 DOI: 10.3390/pharmaceutics15112621] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 10/31/2023] [Accepted: 11/10/2023] [Indexed: 11/26/2023] Open
Abstract
This study explores the potential of a natural composite formulation known as ED, consisting of Ecklonia cava (E. cava, family: Lessoniaceae) and Chrysanthemum indicum Linne (C. indicum, family: Asteraceae), in alleviating lung inflammation induced by fine particulate matter (PM2.5). Initial assessments confirmed that neither ED nor one of its components, dieckol, exhibited cytotoxic effects on A549 cells. Subsequently, the impact of ED and dieckol on MUC5AC gene expression in A549 cells stimulated by phorbol 12-myristate 13-acetate (PMA) was investigated, revealing promising results that demonstrated a dose-dependent inhibition of MUC5AC gene expression. The study also delves into the underlying mechanisms, demonstrating that ED and dieckol effectively suppressed the phosphorylation of mitogen-activated protein kinases (MAPKs), including JNK, ERK, and p38, which are known to be involved in the regulation of MUC5AC gene expression. In in vivo experiments using a PM2.5-induced pulmonary inflammation mouse model, the research findings showed that ED mitigated cellular accumulation in the airways, leading to a significant reduction in the total cell count in bronchoalveolar lavage fluid (BALF). Moreover, ED exhibited protective effects against PM2.5-induced pulmonary damage, characterized by reduced inflammatory cell infiltration and decreased mucus secretion in pulmonary tissues. Additionally, ED's anti-inflammatory properties were evident in its ability to decrease the levels of key inflammatory cytokines, TNF-α and IL-6, both in the serum and lung tissue of the PM2.5-induced pulmonary inflammation mouse model. These findings suggest the potential of ED as a therapeutic agent for inflammatory respiratory diseases.

Abstract
Introduction T-cell immunoglobulin and mucin domain-3 (TIM-3) is a transmembrane molecule first identified as an immunoregulator. This molecule is also expressed on leukemic cells in acute myeloid leukemia and master cell survival and proliferation. In this study, we aimed to explore the effect of TIM-3 interaction with its ligand galectin-9 (Gal-9) on glucose and lipid metabolism in AML cell lines. Methods HL-60 and THP-1 cell lines, representing M3 and M5 AML subtypes, respectively, were cultured under appropriate conditions. The expression of TIM-3 on the cell surface was ascertained by flow cytometric assay. We used real-time PCR to examine the mRNA expression of GLUT-1, HK-2, PFKFB-3, G6PD, ACC-1, ATGL, and CPT-1A; colorimetric assays to measure the concentration of glucose, lactate, GSH, and the enzymatic activity of G6PD; MTT assay to determine cellular proliferation; and gas chromatography-mass spectrometry (GC-MS) to designate FFAs. Results We observed the significant upregulated expression of GLUT-1, HK-2, PFKFB-3, ACC-1, CPT-1A, and G6PD and the enzymatic activity of G6PD in a time-dependent manner in the presence of Gal-9 compared to the PMA and control groups in both HL-60 and THP-1 cell lines (p > 0.05). Moreover, the elevation of extracellular free fatty acids, glucose consumption, lactate release, the concentration of cellular glutathione (GSH) and cell proliferation were significantly higher in the presence of Gal-9 compared to the PMA and control groups in both cell lines (p < 0.05). Conclusion TIM-3/Gal-9 ligation on AML cell lines results in aerobic glycolysis and altered lipid metabolism and also protects cells from oxidative stress, all in favor of leukemic cell survival and proliferation.

[PMID: 33074126 PMCID: PMC7568195 DOI: 10.1016/j.tranon.2020.100881] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 08/30/2020] [Accepted: 09/21/2020] [Indexed: 02/07/2023] Open
Abstract
Human stanniocalcin-1 (STC1) is a paracrine factor associated with inflammation and carcinogenesis. The role of STC1 in the pro- and anti-inflammatory functions of differentiating macrophage, however, is not clear. In this study, our data showed that phorbol 12-myristate 13-acetate (PMA) treatment induced human leukemia monocytic cells (ThP-1) differentiation to M0 macrophages. The differentiation was accompanied by a significant increase in the mRNA expression levels of STC1, the pro-inflammatory cytokine TNFα, and anti-inflammatory markers, CD163 & CD206. An intermitted removal of PMA treatment reduced the mRNA levels of STC1 and TNFα but had no noticeable effects on the anti-inflammatory markers. The correlation in the expression of STC1 and pro-inflammatory markers in differentiating macrophages was investigated, using siRNASTC1-transfected PMA-induced cells. Consistently, the transcripts levels of TNFα and IL-6 were significantly reduced. Moreover, LPS/IFNγ-induced M1-polarization showed remarkably higher expression levels of STC1 than IL-4/IL-13-induced M2-macrophages and PMA-induced M0-macrophages. Transcriptomic analysis of siRNASTC1-transfected M1-polarized cells revealed an upregulation of TBC1 domain family member 3 (TBC1D3G). The gene regulates the payload of macrophage-released extracellular vesicles to mediate inflammation. The conditioned media from siRNASTC1-transfected M1-polarized cells were found to reduce Hep3B cell motility. The data suggest that the expression of STC1 were associated with macrophage differentiation, but preferentially to M1 polarization.

THE KOREAN JOURNAL OF PHYSIOLOGY & PHARMACOLOGY : OFFICIAL JOURNAL OF THE KOREAN PHYSIOLOGICAL SOCIETY AND THE KOREAN SOCIETY OF PHARMACOLOGY 2020; 24:157-163.

Abstract
Chronic inflammatory airway diseases, such as chronic rhinosinusitis, chronic obstructive pulmonary disease, and asthma, are associated with excessive mucus production. Hence, the regulation of mucus production is important for the treatment of upper and lower airway diseases. Eupatilin is a pharmacologically active ingredient obtained from Artemisia asiatica Nakai (Asteraceae) and exerts potent anti-inflammatory, anti-allergic, and anti-tumor activities. In the present study, we investigated the effect of eupatilin on phorbol 12-myristate 13-acetate (PMA)-induced MUC5AC and MUC5B expression in human airway epithelial cells. We found that eupatilin treatment significantly inhibited PMA-induced mucus secretion in PAS staining. In addition, qRT-PCR results showed that eupatilin dose-dependently decreased the mRNA expression of MUC5AC in human airway epithelial cells. Western blot and immunofluorescence assay also showed that PMA-induced protein expression of MUC5AC was inhibited by eupatilin treatment. Finally, we investigated MAPKs activity after stimulation with PMA using western blot analysis in human airway epithelial cells. The results showed that eupatilin downregulated the levels of phosphorylated p38, ERK, and JNK. In summary, the anti-inflammatory activities of eupatilin, characterized as the suppression of MUC5AC expression and secretion in human airway epithelial cells, were found to be associated with the inhibition of p38/ERK/JNK MAPKs signaling pathway of MUC5AC secretion.

Obtusifolin isolated from the seeds of Cassia obtusifolia regulates the gene expression and production of MUC5AC mucin in airway epithelial cells via affecting NF-κB pathway. Phytother Res 2019; 33:919-928. [PMID: 30632219 DOI: 10.1002/ptr.6284] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Revised: 12/08/2018] [Accepted: 12/13/2018] [Indexed: 12/12/2022]
Abstract
We investigated whether obtusin, obtusifolin, and cassiaside isolated from the seeds of Cassia obtusifolia inhibit the gene expression and production of airway mucin 5AC (MUC5AC). Confluent NCI-H292 cells were pretreated with obtusin, obtusifolin, or cassiaside for 30 min and then stimulated with epidermal growth factor (EGF), phorbol 12-myristate 13-acetate (PMA), or tumor necrosis factor-α (TNF-α) for 24 hr. The MUC5AC mucin gene expression was measured by reverse transcription-polymerase chain reaction. Production of MUC5AC mucin protein was measured by enzyme-linked immunosorbent assay. To elucidate the action mechanism of obtusifolin, effect of obtusifolin on PMA-induced nuclear factor kappa B (NF-κB) signaling pathway was investigated by western blot analysis. Obtusin, obtusifolin, or cassiaside inhibited the expression of MUC5AC mucin gene and the production of MUC5AC mucin protein, induced by EGF, PMA, or TNF-α. Obtusifolin inhibited PMA-induced activation (phosphorylation) of inhibitory kappa B kinase, and thus phosphorylation and degradation of inhibitory kappa B alpha. Obtusifolin inhibited PMA-induced nuclear translocation of NF-κB p65. These results suggest that obtusifolin can regulate the production and gene expression of mucin by acting on airway epithelial cells through regulation of NF-κB signaling pathway.

Abstract
In the present study, we investigated whether tussilagone, a natural product derived from Tussilago farfara, significantly affects the production and gene expression of airway MUC5AC mucin. Confluent NCI-H292 cells were pretreated with tussilagone for 30 min and then stimulated with EGF (epidermal growth factor) or PMA (phorbol 12-myristate 13-acetate) for 24 h or the indicated periods. The MUC5AC mucin gene expression was measured by RT-PCR. Production of MUC5AC mucin protein was measured by ELISA. To elucidate the action mechanism of tussilagone, effect of tussilagone on PMA-induced NF-κB signaling pathway was investigated by western blot analysis. Tussilagone significantly inhibited the production of MUC5AC mucin protein and down-regulated the expression of MUC5AC mucin gene, induced by EGF or PMA. Tussilagone inhibited PMA-induced activation (phosphorylation) of inhibitory kappa B kinase (IKK), and thus phosphorylation and degradation of inhibitory kappa Ba (IκBα). Tussilagone inhibited PMA-induced phosphorylation and nuclear translocation of nuclear factor kappa B (NF-κB) p65. This, in turn, led to the down-regulation of MUC5AC protein production in NCI-H292 cells. These results suggest that tussilagone can regulate the production and gene expression of mucin by acting on airway epithelial cells through regulation of NF-κB signaling pathway.

Abstract
Phorbol ester (PMA or TPA), a tumor promoter, can cause either proliferation or cell cycle arrest, depending on cellular context. For example, in SKBr3 breast cancer cells, PMA hyper-activates the MEK/MAPK pathway, thus inducing p21 and cell cycle arrest. Here we showed that PMA-induced arrest was followed by conversion to cellular senescence (geroconversion). Geroconversion was associated with active mTOR and S6 kinase (S6K). Rapamycin suppressed geroconversion, maintaining quiescence instead. In this model, PMA induced arrest (step one of a senescence program), whereas constitutively active mTOR drove geroconversion (step two). Without affecting Akt phosphorylation, PMA increased phosphorylation of S6K (T389) and S6 (S240/244), and that was completely prevented by rapamycin. Yet, T421/S424 and S235/236 (p-S6K and p-S6, respectively) phosphorylation became rapamycin-insensitive in the presence of PMA. Either MEK or mTOR was sufficient to phosphorylate these PMA-induced rapamycin-resistant sites because co-treatment with U0126 and rapamycin was required to abrogate them. We next tested whether activation of rapamycin-insensitive pathways would shift quiescence towards senescence. In HT-p21 cells, cell cycle arrest was caused by IPTG-inducible p21 and was spontaneously followed by mTOR-dependent geroconversion. Rapamycin suppressed geroconversion, whereas PMA partially counteracted the effect of rapamycin, revealing the involvement of rapamycin-insensitive gerogenic pathways. In normal RPE cells arrested by serum withdrawal, the mTOR/pS6 pathway was inhibited and cells remained quiescent. PMA transiently activated mTOR, enabling partial geroconversion. We conclude that PMA can initiate a senescent program by either inducing arrest or fostering geroconversion or both. Rapamycin can decrease gero-conversion by PMA, without preventing PMA-induced arrest. The tumor promoter PMA is a gero-promoter, which may be useful to study aging in mammals.

Abstract
Background Adenophora triphylla var. japonica is empirically used for controlling airway inflammatory diseases in folk medicine. We evaluated the gene expression and production of mucin from airway epithelial cells in response to lupenone, lupeol and taraxerol derived from Adenophora triphylla var. japonica. Methods Confluent NCI-H292 cells were pretreated with lupenone, lupeol or taraxerol for 30 minutes and then stimulated with tumor necrosis factor α (TNF-α) for 24 hours. The MUC5AC mucin gene expression and production were measured by reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. Additionally, we examined whether lupenone, lupeol or taraxerol affects MUC5AC mucin production induced by epidermal growth factor (EGF) and phorbol 12-myristate 13-acetate (PMA), the other 2 stimulators of airway mucin production. Results Lupenone, lupeol, and taraxerol inhibited the gene expression and production of MUC5AC mucin induced by TNF-α from NCI-H292 cells, respectively. The 3 compounds inhibited the EGF or PMA-induced production of MUC5AC mucin in NCI-H292 cells. Conclusion These results indicated that lupenone, lupeol and taraxerol derived from Adenophora triphylla var. japonica regulates the production and gene expression of mucin, by directly acting on airway epithelial cells. In addition, the results partly explain the mechanism of of Adenophora triphylla var. japonica as a traditional remedy for diverse inflammatory pulmonary diseases.

RESULTS (1) Dioscin and methylprotodioscin suppressed the expression of MUC5AC mucin gene induced by EGF or PMA; (2) dioscin suppressed the production of MUC5AC mucin induced by either EGF at 10(-5) M (p < 0.05) and 10(-6) M (p < 0.05) or PMA at 10(-4) M (p < 0.05), 10(-5) M (p < 0.05) and 10(-6) M (p < 0.05); (3) methylprotodioscin also suppressed the production of MUC5AC mucin induced by either EGF at 10(-4) M (p < 0.05) or PMA at 10(-4) M (p < 0.05). CONCLUSION These results suggest that dioscin and methylprotodioscin isolated from the root of Asparagus cochinchinensis suppress the gene expression and production of MUC5AC mucin, by directly acting on airway epithelial cells, and the results are consistent with the traditional use of Asparagus cochinchinensis as remedy for diverse inflammatory pulmonary diseases.

Abstract
Background In this study, we investigated whether lobetyolin, lobetyol, and methyl linoleate derived from Codonopsis pilosula affect MUC5AC mucin secretion, production, and gene expression from airway epithelial cells. Methods Confluent NCI-H292 cells were pretreated with lobetyolin, lobetyol, or methyl linoleate for 30 minutes and then stimulated with phorbol 12-myristate 13-acetate (PMA) for 24 hours. The MUC5AC mucin gene expression, and mucin protein production and secretion were measured by reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. Results Lobetyolin, lobetyol, and methyl linoleate inhibited the gene expression of MUC5AC mucin induced by PMA; lobetyolin did not affect PMA-induced MUC5AC mucin production. However, lobetyol and methyl linoleate inhibited the production of MUC5AC mucin; lobetyolin and lobetyol did not significantly affect PMA-induced MUC5AC mucin secretion from NCI-H292 cells. However, methyl linoleate decreased the MUC5AC mucin secretion. Conclusion These results suggest that among the three compounds, methyl linoleate can regulate gene expression, production, and secretion of MUC5AC mucin by directly acting on the airway epithelial cells.

Abstract
Background It is valuable to find the potential activity of regulating the excessive mucin secretion by the compounds derived from various medicinal plants. We investigated whether aqueous extract of the root bark of Morus alba L. (AMA), kuwanon E, kuwanon G, mulberrofuran G, and morusin significantly affect the secretion and production of airway mucin using in vivo and in vitro experimental models. Methods Effect of AMA was examined on hypersecretion of airway mucin in sulfur dioxide-induced acute bronchitis in rats. Confluent NCI-H292 cells were pretreated with ethanolic extract, kuwanon E, kuwanon G, mulberrofuran G, or morusin for 30 minutes and then stimulated with phorbol 12-myristate 13-acetate (PMA) for 24 hours. The MUC5AC mucin secretion and production were measured by enzyme-linked immunosorbent assay. Results AMA stimulated the secretion of airway mucin in sulfur dioxide-induced bronchitis rat model; aqueous extract, ethanolic extract, kuwanon E, kuwanon G, mulberrofuran G and morusin inhibited the production of MUC5AC mucin induced by PMA from NCI-H292 cells, respectively. Conclusion These results suggest that extract of the root bark and the natural products derived from Morus alba L. can regulate the secretion and production of airway mucin and, at least in part, explains the folk use of extract of Morus alba L. as mucoregulators in diverse inflammatory pulmonary diseases.

Abstract
We investigated whether aqueous extract of the root of Platycodon grandiflorum A. de Candolle (APG), platycodinD(3) and deapi-platycodin significantly affect the production and secretion of airway mucin using in vivo and in vitro experimental models. Effect of APG was checked on hypersecretion of pulmonary mucin in sulfur dioxide-induced bronchitis in rats. Confluent NCI-H292 cells were pretreated with platycodinD(3) or deapi-platycodin for 30min and then stimulated with PMA (phorbol 12-myristate 13-acetate) for 24h. The MUC5AC mucin production and secretion were measured by ELISA. The results were as follows: (1) APG stimulated the secretion of airway mucin in sulfur dioxide-induced bronchitis rat model; (2) platycodinD(3) and deapi-platycodin inhibited the production of MUC5AC mucin induced by PMA from NCI-H292 cells, respectively; (3) however, platycodinD(3) and deapi-platycodin did not inhibit but stimulated the secretion of MUC5AC mucin induced by PMA from NCI-H292 cells, respectively. This result suggests that aqueous extract of P. grandiflorum A. de Candolle and the two natural products derived from it, platycodinD(3) and deapi-platycodin, can regulate the production and secretion of airway mucin and, at least in part, explains the traditional use of aqueous extract of P. grandiflorum A. de Candolle as expectorants in diverse inflammatory pulmonary diseases.

Abstract
In the present study, we investigated whether aqueous extract of Liriope Tuber, ophiopogonin D and spicatoside A derived from Liriope Tuber affect basal or phorbol ester (phorbol 12-myristate 13-acetate, PMA)-induced airway mucin production and secretion from airway epithelial cells. Confluent NCI-H292 cells were treated with each agent for 24 h (basal production) or pretreated with each agent for 30 min and then stimulated with PMA for 24 h (PMA-induced production and secretion), respectively. MUC5AC airway mucin production and secretion were measured by ELISA. The results were as follows: (1) aqueous extract of Liriope Tuber stimulated basal mucin production and did not inhibit but increased PMA-induced mucin production; (2) ophiopogonin D and spicatoside A stimulated basal mucin production and did not inhibit but increased PMA-induced mucin production; (3) two compounds increased PMA-induced mucin secretion. These results suggest that ophiopogonin D and spicatoside A can increase mucin production and secretion, by directly acting on airway epithelial cells and, at least in part, explain the traditional use of aqueous extract of Liriope Tuber as expectorants in diverse inflammatory pulmonary diseases.

Abstract
Background We investigated whether chrysin affected MUC5AC mucin production and gene expression induced by phorbol ester (phorbol 12-myristate 13-acetate, PMA) or epidermal growth factor (EGF) from human airway epithelial cells. Methods Confluent NCI-H292 cells were pretreated with varying concentrations of chrysin for 30 minutes, and were then stimulated with PMA and EGF for 24 hours, respectively. MUC5AC mucin gene expression and mucin protein production were measured by reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assay. Results Concentrations of 10µM and 100µM chrysin were found to inhibit the production of MUC5AC mucin protein induced by PMA; A concentration of 100µM chrysin also inhibited the production of MUC5AC mucin protein induced by EGF; 100µM chrysin inhibited the expression of MUC5AC mucin gene induced by PMA or EGF. The cytotoxicity of chrysin was checked by lactate dehydrogenase assay, and there was no cytotoxic effect observed for chrysin. Conclusion These results suggest that chrysin can inhibit mucin gene expression and the production of mucin protein by directly acting on airway epithelial cells.

Abstract
The study investigated whether resveratrol significantly affects mucin gene expression, production and secretion from airway epithelial cells. Confluent NCI-H292 cells were pretreated with resveratrol for 30 min and then stimulated with EGF (epidermal growth factor), PMA (phorbol 12-myristate 13-acetate) and TNF-α (tumor necrosis factor-α) for 24 h, respectively. The MUC5AC gene expression and mucin protein production were measured by RT-PCR and ELISA. The effect of resveratrol on TNF-α- or PMA-induced activation of NF-κB p65 was also examined. Confluent primary rat tracheal surface epithelial (RTSE) cells were pretreated with adenosine triphosphate (ATP) for 5 min and then treated for 30 min in the presence of resveratrol to assess the effect on mucin secretion using ELISA. The results were as follows: (1) resveratrol inhibited the expression of MUC5AC gene induced by EGF or PMA or TNF-α from NCI-H292 cells; (2) resveratrol also inhibited the production of MUC5AC mucin protein induced by the same inducers from NCI-H292 cells; (3) resveratrol inhibited the activation of NF-κB p65 by TNF-α or PMA in NCI-H292 cells; (4) resveratrol significantly decreased ATP-induced mucin secretion from cultured RTSE cells. This result suggests that resveratrol can regulate mucin gene expression, production and secretion, by directly acting on airway epithelial cells.

Confluent NCI-H292 cells were pretreated with each agent for 30 min and then stimulated with EGF and PMA for 24 h, respectively. MUC5AC mucin gene expression and mucin protein production were measured by RT-PCR and ELISA. Oleanolic acid and ursolic acid were found to inhibit the production of MUC5AC mucin protein induced by EGF and PMA, and both compounds also inhibited the expression of MUC5AC mucin gene induced by EGF and PMA. These results suggest that oleanolic acid and ursolic acid can regulate mucin gene expression, and production of mucin protein, by directly acting on airway epithelial cells.

Combined inhibition of PI3K and mTOR exerts synergistic antiproliferative effect, but diminishes differentiative properties of rapamycin in acute myeloid leukemia cells.

Abstract
A novel strategy has been suggested to enhance rapamycin-based cancer therapy through combining mammalian target of rapamycin (mTOR)-inhibitors with an inhibitor of the phosphatydilinositol 3-kinase PI3K/Akt or mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathway. However, recent study demonstrated the potentiating effect of rapamycin on all-trans-retinoic acid (ATRA)-mediated differentiation of acute myelogenous leukemia (AML) cells, prompting us to investigate the effects of longitudinal inhibition of PI3K/Akt/mTOR signaling pathway on both proliferation and differentiative capacity of AML. In NB4, HL-60, U937 and K562 cell lines, rapamycin exerted minimal antiproliferative effects, and combining PI3K inhibitor LY 294002 and rapamycin inhibited proliferation more than LY 294002 alone. Rapamycin potentiated differentiation of ATRA-treated NB4 cells, but the combination of rapamycin and LY 294002 inhibited the expression of CD11b in both ATRA- and phorbol myristate acetate (PMA)-stimulated cells more than PI3K inhibitor alone. These results demonstrate that, although the combination of PI3K inhibitor and rapamycin is more effective in inhibiting proliferation of AML, the concomitant inhibition of PI3K and mTOR by LY 294002 and rapamycin has more inhibitory effects on ATRA-mediated differentiation than the presence of PI3K-inhibitor alone, and diminishes positive effects of rapamycin on leukemia cell differentiation.

Abstract
This study investigated whether prunetin significantly affects the secretion, production and gene expression of mucin from cultured airway epithelial cells. Confluent primary rat tracheal surface epithelial (RTSE) cells were pretreated with adenosine triphosphate (ATP) for 5 min and then chased for 30 min in the presence of prunetin to assess the effect on mucin secretion using enzyme-linked immunosorbent assay (ELISA). At the same time, confluent NCI-H292 cells were pretreated with prunetin for 30 min and then stimulated with epidermal growth factor (EGF) or phorbol 12-myristate 13-acetate (PMA) for 24 h, respectively. The MUC5AC mucin gene expression and mucin protein production were measured by reverse transcription-polymerase chain reaction (RT-PCR) and ELISA. The results were as follows: (1) prunetin significantly suppressed ATP-induced mucin secretion from cultured RTSE cells; (2) prunetin inhibited the production of MUC5AC mucin protein induced by EGF or PMA from NCI-H292 cells; (3) prunetin also inhibited the expression of MUC5AC mucin gene induced by EGF or PMA from NCI-H292 cells. This result suggests that prunetin can regulate the secretion, production and gene expression of mucin, by directly acting on airway epithelial cells.

Abstract
Lysozyme is a major component of airway epithelial secretions, acts as cationic anti-microbial protein for innate immunity. Although lysozyme plays an important role in airway defense and is a key component of airway secretions under inflammatory conditions, little is understood about the regulation of its expression and the associated signaling pathway. We wanted to examine whether Phorbol 12-myristate 13-acetate (PMA), one of PKC activators, treatment of the airway epithelial cell line NCI-H292 increases lysozyme gene expression. In this study, we sought to determine which signal molecules are involved in PMA-induced lysozyme gene expression. We found that PKC and mitogen-activating protein/ERK2 kinase are essential for PMA-induced lysozyme expression and also mediate the PMA-induced activation of c-Myb protein. We identified a proximal region of the lysozyme promoter essential for promoter activity containing c-Myb transcription factor binding site. Additionally, by site-directed promoter mutagenesis, we identified that c-Myb preferred the CAA motif of the -85/-73 region of the lysozyme promoter. Finally, we showed that overexpression of c-Myb without PMA treatment increased the lysozyme promoter activity and protein expression. From these results, we conclude that PMA induces overexpression of lysozyme via ERK1/2 MAP kinase-c-Myb signaling pathways in NCI-H292 cells.

Abstract
We previously showed that the MUC5B gene expression was elevated by phorbol 12-myristate 13-acetate (PMA) through an epidermal growth factor receptor-independent Ras/MEKK1/JNK and P38 signaling-based transcriptional mechanism. In the current study, we elucidated the molecular basis of this transcriptional regulation using promoter-reporter gene expression and chromatin immunoprecipitation (ChIP) assays with primary human bronchial epithelial cells that are cultured at the air-liquid interface. We have observed that PMA-induced MUC5B promoter activity is blocked by the Sp1-binding inhibitor, mithramycin A, in a dose-dependent manner. Deletion analysis with the MUC5B promoter construct demonstrated that both basal and PMA-induced promoter-reporter activities reside within the -222/-78 bp region relative to the transcriptional start site. NoShift transcriptional factor assays demonstrated that PMA stimulated Sp1 binding, but not STAT1 and c-Myc binding. Immunoprecipitation studies also verified the enhanced phosphorylation of Sp1 after PMA treatment. Site-directed mutagenesis and transfection studies demonstrated the involvement of Sp1-1 (-122/-114) and the Sp1-2 (-197/-186) cis elements in the basal and PMA-induced MUC5B promoter activity. The ChIP assay with anti-RNA polymerase II reconfirmed the PMA-induced MUC5B promoter activity by showing enhanced RNA polymerase II-DNA complex containing putative MUC5B Sp1-1, Sp1-2, or Sp1-3 sites. However, the ChIP assay using anti-Sp1 antibody demonstrated that the PMA-stimulated binding is only at Sp1-2. These results suggested an Sp1-based transcriptional mechanism with Sp1-1 as the regulator of basal MUC5B promoter activity and Sp1-2 as the regulator of PMA-induced MUC5B gene expression in the human airway epithelial cells.

Abstract
Elevated expression of gel-forming mucin (MUC) genes MUC5AC and MUC5B is a major pathological feature in various airway diseases. In this study, we show that phorbol 12-myristate 13-acetate (PMA) is a potent stimulator for MUC5B gene expression under air-liquid interface conditions in three airway epithelial cell systems: primary cultures of normal human bronchial epithelial cells, the immortalized normal bronchial epithelial cell line HBE1, and the human lung adenocarcinoma cell line A549. Stimulation was time- and dose-dependent, could be demonstrated by promoter-reporter gene transfection, and was sensitive to mithramycin A, suggesting the involvement of a specificity protein 1-based transcriptional mechanism in the stimulation. PMA-induced MUC5B message and promoter-reporter gene activity were specifically sensitive to inhibition of protein kinase C delta, which was further confirmed by the forced expression of dominant-negative mutant of protein kinase C delta. Regarding downstream transduction, PMA-induced MUC5B expression was sensitive to inhibitors and dominant-negative expression of signaling molecules involved in Ras/mitogen-activated protein kinase/extracellular signal-regulated kinase kinase kinase1-mediated c-Jun N-terminal kinase and p38 pathways. This contrasted with the inhibition of PMA-induced MUC5AC expression by inhibitors of the Ras/epidermal growth factor receptor/extracellular regulated kinase signaling pathway. These results demonstrate for the first time that PMA-stimulated MUC5AC and MUC5B expressions are regulated through distinctive epidermal growth factor receptor/extracellular regulated kinase-dependent and -independent signaling pathways.

Abstract
Human peripheral CD14(+)monocytes have been known to differentiate into monocyte-derived macrophages (MDMs) or dendritic cells (MoDCs) upon suitable stimulation. However, the key intracellular molecule(s) associated with their differentiation towards specific cell types was(were) not fully understood. This study was designated to determine the association of PKC isoenzymes with the differentiation of CD14(+)monocytes into MDMs or MoDCs. Purified human peripheral CD14(+)monocytes were cultured with GM-CSF, or GM-CSF plus IL-4 for 7 days to induce cell differentiation. The phenotypic changes were analyzed by Flow-Cytometry using various specific antibodies to cell type-specific surface markers. The immunological functions of these differentiated cells were determined by measuring the amounts of TNF-alpha secretion for MDMs, and the capacities of antigen-capturing and bacterial phagocytosis for MoDCs. The translocations of PKC isoenzymes in these cells from cytosol to plasma membrane were examined by Western Blot analysis and Confocal Microscopic observation. The treatment of CD14(+)monocytes with either GM-CSF or PMA elicited PKCalpha translocation and consequently induced their differentiation into MDMs. The inclusion of PKCalpha/beta(I) specific inhibitor, Go6976, greatly inhibited the GM-CSF-induced PKCalpha translocation and dose-dependently reduced the GM-CSF- induced MDM differentiation. On the other hand, the simultaneous pretreatment of CD14(+)monocytes with Go6976 and PKCbeta-specific inhibitor predominantly suppressed the GM-CSF/IL-4-induced generation of MoDCs. Further study demonstrated that GM-CSF/IL-4 selectively induced the translocation of PKCbeta(I), not PKCalpha or PKCbeta(II), in CD14(+)monocytes. In conclusion, the cell fate commitment of CD14(+)monocytes towards MDMs or MoDCs appears to be steered by the selective activation of PKCalpha or PKCbeta(I), respectively.

Abstract
FLICE-like inhibitory protein (FLIP), a naturally occurring caspase-inhibitory protein that lacks the critical cysteine domain necessary for catalytic activity, is a negative regulator of Fas-induced apoptosis. Decreased FLIP levels sensitize tumor cells to Fas- and TRAIL-mediated apoptosis; however, the cellular mechanisms regulating FLIP expression have not been defined. Here, we examined the roles of the PKC and NF-kappaB pathway in the regulation of FLIP in human colon cancers. FLIP mRNA levels were increased in Caco-2 cells by treatment with PMA; actinomycin D completely inhibited the induction of FLIP by PMA, indicating transcriptional regulation. PKC inhibitors Gö6983 and Ro-31-8220 blocked PMA-stimulated FLIP expression. Pretreatment with the PKCdelta-selective inhibitor rottlerin or transfection with PKCdelta siRNA inhibited PMA-induced FLIP expression, which identifies a role for PKCdelta in FLIP induction. Treatment with the proteasome inhibitor, MG132, or the NF-kappaB inhibitor (e.g., PDTC and gliotoxin), or overexpression of the superrepressor of IkappaB-alpha inhibited PMA-induced upregulation of FLIP. Moreover, PMA-induced NF-kappaB transactivation was blocked by GF109203x. In conclusion, our results demonstrate a critical role for PKCdelta/NF-kappaB in the regulation of FLIP in human colon cancer cells.

Abstract
Major trauma such as severe bums and extensive surgery could result in accelerated macrophage differentiation and hyperactivation causing an excessive release of proinflammatory cytokines and prostaglandin E2 (PGE2) with consequent severe impairment of immunologic reactivity. HL-60 cells stimulated with phorbol 12-myristate 13-acetate (PMA) have been used as a model to asses the PGE2 role in the macrophage differentiation observed after major trauma. Cell adhesion, matrix metalloproteinase-9 (MMP-9) and tumor necrosis factor-alpha (TNF-alpha) production were measured after 24 h of PMA treatment in the presence of PGE2 (1 nM - 1 microM). PGE2 increased both the PMA-induced cell adhesion and MMP-9 production via EP2/EP4 receptors while it had no effect on the induced TNF-alpha release. The cAMP/PKA pathway, usually linked to EP2/EP4 activation, was not involved in the phenomenon, suggesting that an alternative signalling pathway could be linked to a PKC-activated enzyme. In fact PGE2 activity was partially inhibited by Wortmannin, a phosphoinositide-3 kinase (PI-3K) inhibitor indicating that PGE2 act as a co-factor able to increase macrophage differentiation in vitro via a PI-3K dependent pathway that could be also involved in the immunosuppression observed in the aftermath of trauma.

Abstract
Activation of protein kinase C (PKC) prevents apoptosis in certain cells; however, the mechanisms are largely unknown. Inhibitors of apoptosis (IAP) family members, including NAIP, cIAP-1, cIAP-2, XIAP/hILP, survivin, and BRUCE, block apoptosis by binding and potently inhibiting caspases. Activation of NF-kappa B contributes to cIAP-2 induction; however, the cellular mechanisms regulating cIAP-2 expression have not been entirely defined. In this study, we examined the role of the PKC and NF-kappa B pathways in the regulation of cIAP-2 in human colon cancers. We found that cIAP-2 mRNA levels were markedly increased in human colon cancer cells by treatment with the phorbol ester, phorbol-12-myristate-13-acetate (PMA), or bryostatin 1. Inhibitors of the Ca2+-independent, novel PKC isoforms, but not inhibitors of MAPK, PI3-kinase, or PKA, blocked PMA-stimulated cIAP-2 mRNA expression, suggesting a role of PKC in PMA-mediated cIAP-2 induction. Pretreatment with the PKC delta-selective inhibitor rottlerin or transfection with an antisense PKC delta oligonucleotide inhibited PMA-induced cIAP-2 expression, whereas cotransfection with a PKC delta plasmid induced cIAP-2 promoter activity, which, taken together, identifies a role for PKC delta in cIAP-2 induction. Treatment with the proteasome inhibitor, MG132 or inhibitors of NF-kappa B (e.g. PDTC and gliotoxin), decreased PMA-induced up-regulation of cIAP-2. PMA-induced NF-kappa B activation was blocked by either GF109203x, MG132, PDTC, or gliotoxin. Moreover, overexpression of PKC delta-induced cIAP-2 promoter activity and increased NF-kappa B transactivation, suggesting regulation of cIAP-2 expression by a PKC delta/NF-kappa B pathway. In conclusion, our findings demonstrate a role for a PKC/NF-kappa B-dependent pathway in the regulation of cIAP-2 expression in human colon cancer cells. These data suggest a novel mechanism for the anti-apoptotic function mediated by the PKC delta/NF-kappa B/cIAP-2 pathway in certain cancers.

Abstract
Effects of the PI-3 kinase inhibitor LY294002 (LY) have been examined in relation to responses of human leukemia cells to histone deacetylase inhibitors (HDIs). Coexposure of U937 cells for 24 h to marginally toxic concentrations of LY294002 (e.g., 30 microM) and sodium butyrate (SB; 1 mM) resulted in a marked increase in mitochondrial damage (e.g., cytochrome c and Smac/DIABLO release, loss of DeltaPsi(m)), caspase activation, and apoptosis. Similar results were observed in Jurkat, HL-60, and K562 leukemic cells and with other HDIs (e.g., SAHA, MS-275). Exposure of cells to SB/LY was associated with Bcl-2 and Bid cleavage, XIAP and Mcl-1 downregulation, and diminished CD11b expression. While LY blocked SB-mediated Akt activation, enforced expression of a constitutively active (myristolated) Akt failed to attenuate SB/LY-mediated lethality. Unexpectedly, treatment of cells with SB+/-LY resulted in a marked reduction in phosphorylation (activation) of p44/42 mitogen-activated protein (MAP) kinase. Moreover, enforced expression of a constitutively active MEK1 construct partially but significantly attenuated SB/LY-induced apoptosis. Lastly, cotreatment with LY blocked SB-mediated induction of p21(CIP1/WAF1); moreover, enforced expression of p21(CIP1/WAF1) significantly reduced SB/LY-mediated apoptosis. Together, these findings indicate that LY promotes SB-mediated apoptosis through an AKT-independent process that involves MEK/MAP kinase inactivation and interference with p21(CIP1/WAF1) induction.
