ADAMTS1 (a disintegrin and metalloproteinase with thrombospondin motifs 1) is an inflammatory-induced gene. We have previously reported that ADAMTS1 was strongly but transiently expressed in the infarcted heart. In this study, we investigated whether a 3'-untranslated region (UTR) affects the mRNA stability of this gene. When stimulated with tissue necrosis factor (TNF)-alpha, the expression level of ADAMTS1 mRNA rapidly increased, but the induction of ADAMTS1 mRNA peaked at 6h after stimulation, after which the expression levels of ADAMTS1 mRNA decreased. The 3'-UTR ADAMTS1 mRNA contains multiple adenine and uridine-rich elements, suggesting that the 3'-UTR may regulate gene stability. The addition of actinomycin D, an RNA synthesis inhibitor, demonstrated the decay of induced ADAMTS1 mRNA by TNF-alpha. Furthermore, a region containing multiple AUUUA motifs within the ADAMTS1 3'-UTR destabilized transfected Enhanced Green Fluorescence Protein (EGFP) mRNA expression. These results demonstrated that the ADAMTS1 3'-UTR may regulate the expression of ADAMTS1 mRNA.

Objective
To compare induction of the aggrecanases (ADAMTS-1, ADAMTS-4, ADAMTS-5, ADAMTS-8, ADAMTS-9, and ADAMTS-15) by interleukin-1 (IL-1) and tumor necrosis factor (TNF) in chondrocyte-like OUMS-27 cells and human chondrocytes, and to determine the mechanism of induction of the most responsive aggrecanase gene.

Methods
OUMS-27 cells were stimulated for different periods of time and with various concentrations of IL-1 and/or TNF. Human chondrocytes obtained from osteoarthritic joints and human skin fibroblasts were also stimulated with IL-1 and/or TNF. Total RNA was extracted, reverse transcribed, and analyzed by quantitative real-time polymerase chain reaction and Northern blotting. ADAMTS-9 protein was examined by Western blotting, and the role of the MAPK signaling pathway for ADAMTS9 induction in IL-1-stimulated OUMS-27 cells was investigated.

Results IL-1 increased messenger RNA (mRNA) levels of ADAMTS4, ADAMTS5, and ADAMTS9 but not ADAMTS1 and ADAMTS8. The fold increase for ADAMTS9 mRNA was greater than that for mRNA of the other aggrecanase genes. The increase of ADAMTS9 mRNA by IL-1 stimulation was greater in chondrocytes than in fibroblasts. The combination of IL-1 and TNF had a synergistic effect, resulting in a considerable elevation in the level of ADAMTS9 mRNA. ADAMTS-9 protein was also induced in IL-1-stimulated OUMS-27 cells. The MAPK inhibitors SB203580 and PD98059 decreased ADAMTS9 up-regulation in OUMS-27 cells.

Conclusion
ADAMTS9 is an IL-1- and TNF-inducible gene that appears to be more responsive to these proinflammatory cytokines than are other aggrecanase genes. Furthermore, these cytokines had a synergistic effect on ADAMTS9. Together with the known ability of ADAMTS-9 to proteolytically degrade aggrecan and its potential to cleave other cartilage molecules, the data suggest that ADAMTS-9 may have a pathologic role in arthritis.

To test the hypothesis that versican expression is transiently upregulated and plays a role in the infarcted heart, we examined its expression in a rat model of myocardial infarction. Northern blot analysis demonstrated increased expression of versican mRNA. Quantitative real-time RT-PCR analysis revealed that versican mRNA began to increase as early as 6 h and reached its maximal level 2 days after coronary artery ligation. Versican mRNA then gradually decreased, while the mRNA of decorin, another small proteoglycan, increased thereafter. Versican mRNA was localized in monocytes, as indicated by CD68-positive staining, around the infarct tissue. The induction of versican mRNA was accelerated by ischemia/reperfusion (I/R), which was characterized by massive cell infiltration and enhanced inflammatory response. To examine the alteration of versican expression in monocytes/macrophages, we isolated human peripheral blood mononuclear cells and stimulated them with granulocyte/macrophage colony-stimulating factor (GM-CSF). Stimulation of mononuclear cells with GM-CSF increased the expression of versican mRNA as well as cytokine induction. The production of versican by monocytes in the infarct area represents a novel finding of the expression of an extracellular matrix gene by monocytes in the infarcted heart. We suggest that upregulation of versican in the infarcted myocardium may have a role in the inflammatory reaction, which mediates subsequent chemotaxis in the infarcted heart. en-copyright= kn-copyright= en-aut-name=ToedaKenichi en-aut-sei=Toeda en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakamuraKeigo en-aut-sei=Nakamura en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HatipogluOmer F. en-aut-sei=Hatipoglu en-aut-mei=Omer F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DemircanKadir en-aut-sei=Demircan en-aut-mei=Kadir kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamawakiHitoshi en-aut-sei=Yamawaki en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaHiroko en-aut-sei=Ogawa en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KusachiShozo en-aut-sei=Kusachi en-aut-mei=Shozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShiratoriYasushi en-aut-sei=Shiratori en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NinomiyaYoshifumi en-aut-sei=Ninomiya en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Medicine and Medical Science, Okayama University Graduate School of Medicine and Dentistry affil-num=2 en-affil= kn-affil=Department of Medicine and Medical Science, Okayama University Graduate School of Medicine and Dentistry affil-num=3 en-affil= kn-affil=Department of Medicine and Medical Science, Okayama University Graduate School of Medicine and Dentistry affil-num=4 en-affil= kn-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine and Dentistry affil-num=5 en-affil= kn-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine and Dentistry affil-num=6 en-affil= kn-affil=Department of Medicine and Medical Science, Okayama University Graduate School of Medicine and Dentistry affil-num=7 en-affil= kn-affil=Department of Medicine and Medical Science, Okayama University Graduate School of Medicine and Dentistry affil-num=8 en-affil= kn-affil=Department of Medicine and Medical Science, Okayama University Graduate School of Medicine and Dentistry affil-num=9 en-affil= kn-affil=Department of Medicine and Medical Science, Okayama University Graduate School of Medicine and Dentistry affil-num=10 en-affil= kn-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine and Dentistry en-keyword=coronary artery disease kn-keyword=coronary artery disease en-keyword=cytokine kn-keyword=cytokine en-keyword=extracellular matrix kn-keyword=extracellular matrix en-keyword=GM-CSF kn-keyword=GM-CSF en-keyword=monocyte kn-keyword=monocyte END start-ver=1.4 cd-journal=joma no-vol=69 cd-vols= no-issue=3 article-no= start-page=145 end-page=153 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Eosinophil Cationic Protein Shows Survival Effect on H9c2 Cardiac Myoblast Cells with Enhanced Phosphorylation of ERK and Akt/GSK-3β under Oxidative Stress en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eosinophil cationic protein (ECP) is well known as a cationic protein contained in the basic granules of activated eosinophils. Recent studies have reported that ECP exhibits novel activities on various types of cells, including rat neonatal cardiomyocytes. Here we evaluated the effects of ECP on rat cardiac myoblast H9c2 cells. Our results showed that ECP enhanced the survival of the cells, in part by promoting the ERK and Akt/GSK-3β signaling pathways. ECP attenuated the cytotoxic effects of H2O2 on H9c2 cells as well as the production of reactive oxygen species, the number of apoptotic cells and caspase 3/7 activity in the cells. In conclusion, ECP activated the ERK and Akt/GSK-3β pathways, resulting in anti-oxidative effects on H9c2 cells that attenuated apoptosis. en-copyright= kn-copyright= en-aut-name=IshiiHiroko en-aut-sei=Ishii en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KamikawaShigeshi en-aut-sei=Kamikawa en-aut-mei=Shigeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirohataSatoshi en-aut-sei=Hirohata en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizutaniAkifumi en-aut-sei=Mizutani en-aut-mei=Akifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AbeKoji en-aut-sei=Abe en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SenoMasaharu en-aut-sei=Seno en-aut-mei=Masaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OohashiToshitaka en-aut-sei=Oohashi en-aut-mei=Toshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NinomiyaYoshifumi en-aut-sei=Ninomiya en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Departments of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine affil-num=2 en-affil= kn-affil=Departments of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine affil-num=3 en-affil= kn-affil=Departments of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine affil-num=4 en-affil= kn-affil=Department of Chemistry and Biotechnology, Graduate School of Natural Science and Technology, Okayama University affil-num=5 en-affil= kn-affil=Neurology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, affil-num=6 en-affil= kn-affil=Department of Chemistry and Biotechnology, Graduate School of Natural Science and Technology, Okayama University affil-num=7 en-affil= kn-affil=Departments of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine affil-num=8 en-affil= kn-affil=Departments of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine en-keyword=ECP kn-keyword=ECP en-keyword=reactive oxygen species kn-keyword=reactive oxygen species en-keyword=Akt kn-keyword=Akt en-keyword=ERK kn-keyword=ERK END
