It was found in the present study that NaHS at 0.1\u201310 \u03bcM significantly decreased cAMP production in As4.1 cells treated with isoproterenol (a \u03b2-adrenoceptor agonist), forskolin (an adenylyl cyclase activator), or 3-isobutyl-1-methylxanthine (IBMX, a phosphodiesterase inhibitor). NaHS at 10 \u03bcM suppressed adenylate cyclase activity but stimulated phosphodiesterase activity. We continued to study whether H<jats:sub>2<\/jats:sub>S may mediate cAMP-dependent renin degranulaion in As4.1 cells. It was found that NaHS at 0.1\u201310 \u03bcM significantly increased intracellular renin protein level. Moreover, NaHS reversed the declined renin content within As4.1 cells and normalized the upregulated renin activity in the culture medium of As4.1 cells treated with the above three stimuli. RT-PCR showed that cystathionine-\u03b3-lyase is the main enzyme to produce endogenous H<jats:sub>2<\/jats:sub>S in As4.1 cells. Overexpression of cystathionine-\u03b3-lyase increased endogenous H<jats:sub>2<\/jats:sub>S production and suppressed isoproterenol-induced renin release, suggesting that endogenous H<jats:sub>2<\/jats:sub>S may also inhibit renin release from As4.1 cells. We also tested whether H<jats:sub>2<\/jats:sub>S has a similar effect in renin-rich kidney cells. It was found that isoproterenol elevated intracellular cAMP level and extracellular renin activity but decreased renin protein level in the renin-rich kidney cells. Pretreatment with NaHS abolished these effects. In conclusion, H<jats:sub>2<\/jats:sub>S regulates cAMP homeostasis via inhibition of adenylate cyclase and stimulation of phosphodiesterase. Our findings suggest that H<jats:sub>2<\/jats:sub>S plays a critical role in regulation of renin degranulation in As4.1 and rat renin-rich kidney cells. <\/jats:p>","DOI":"10.1152\/ajpcell.00341.2010","type":"journal-article","created":{"date-parts":[[2011,9,23]],"date-time":"2011-09-23T01:32:58Z","timestamp":1316741578000},"page":"C59-C66","source":"Crossref","is-referenced-by-count":35,"title":["Hydrogen sulfide regulates cAMP homeostasis and renin degranulation in As4.1 and rat renin-rich kidney cells"],"prefix":"10.1152","volume":"302","author":[{"given":"Ming","family":"Lu","sequence":"first","affiliation":[{"name":"Department of Pharmacology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-Hong","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chui Ying","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chi Xin","family":"Tiong","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-Song","family":"Bian","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"24","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1152\/ajprenal.1998.275.6.F991"},{"key":"B1a","author":"Beierwaltes WH","year":"2011","journal-title":"Am J Physiol Cell Physiol"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1124\/jpet.105.092023"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.84.8.929"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1093\/ndt\/gfh857"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.0000017622.25365.71"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1152\/ajpregu.90566.2008"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1152\/physrev.1990.70.4.1067"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1124\/mol.108.047985"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1089\/ars.2008.2132"},{"key":"B10","first-page":"951","volume":"25","author":"Jiang HL","year":"2005","journal-title":"Di Yi Jun Yi Da Xue Xue Bao"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.10.5.488"},{"key":"B12","doi-asserted-by":"publisher","DOI":"10.1152\/ajpcell.00195.2008"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2009090949"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1016\/S0008-6363(00)00322-9"},{"key":"B15","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcb.2006.01.005"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1016\/j.yjmcc.2005.10.003"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1152\/physiol.00024.2007"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1096\/fj.02-0211hyp"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bjp.0706063"},{"key":"B20","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M408997200"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1016\/j.yjmcc.2008.01.007"},{"key":"B22","doi-asserted-by":"publisher","DOI":"10.1093\/emboj\/20.21.6008"}],"container-title":["American Journal of Physiology-Cell Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.physiology.org\/doi\/pdf\/10.1152\/ajpcell.00341.2010","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,6,17]],"date-time":"2024-06-17T16:54:06Z","timestamp":1718643246000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.physiology.org\/doi\/10.1152\/ajpcell.00341.2010"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,1]]},"references-count":23,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2012,1]]}},"alternative-id":["10.1152\/ajpcell.00341.2010"],"URL":"https:\/\/doi.org\/10.1152\/ajpcell.00341.2010","relation":{},"ISSN":["0363-6143","1522-1563"],"issn-type":[{"value":"0363-6143","type":"print"},{"value":"1522-1563","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,1]]}}}
