Three enzymes mediate the endogenous production of H2S: cystathione \u03b2-synthase (CBS), cystathione \u03b3-lyase (CSE) and 3-mercaptopyruvate sulfurtransferase (3-MST). CBS and CSE localizations are organ-specific. 3-MST is a mitochondrial and cytosolic enzyme. The generation of H2S is firmly regulated by these enzymes under normal physiological conditions. Recent studies have highlighted the role of H2S in cellular redox homeostasis, as it displays significant antioxidant properties. H2S exerts antioxidant effects through several mechanisms, such as quenching reactive oxygen species (ROS) and reactive nitrogen species (RNS), by modulating cellular levels of glutathione (GSH) and thioredoxin (Trx-1) or increasing expression of antioxidant enzymes (AOE), by activating the transcription factor nuclear factor (erythroid-derived 2)-like 2 (NRF2). H2S also influences the activity of the histone deacetylase protein family of sirtuins, which plays an important role in inhibiting oxidative stress in cardiomyocytes and during the aging process by modulating AOE gene expression. This review focuses on the role of H2S in NRF2 and sirtuin signaling pathways as they are related to cellular redox homeostasis.<\/jats:p>","DOI":"10.3390\/antiox7100129","type":"journal-article","created":{"date-parts":[[2018,9,28]],"date-time":"2018-09-28T02:54:54Z","timestamp":1538103294000},"page":"129","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":167,"title":["Role of Hydrogen Sulfide in NRF2- and Sirtuin-Dependent Maintenance of Cellular Redox Balance"],"prefix":"10.3390","volume":"7","author":[{"given":"Tiziana","family":"Corsello","sequence":"first","affiliation":[{"name":"Department of Pediatrics, University of Texas Medical Branch at Galveston, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2679-2558","authenticated-orcid":false,"given":"Narayana","family":"Komaravelli","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Texas Medical Branch at Galveston, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonella","family":"Casola","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Texas Medical Branch at Galveston, Galveston, TX 77555, USA"},{"name":"Department of Microbiology and Immunology, University of Texas Medical Branch at Galveston, Galveston, TX 77555, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"864","DOI":"10.1016\/j.bbabio.2009.03.005","article-title":"Physiological and pharmacological features of the novel gasotransmitter: Hydrogen sulfide","volume":"1787","author":"Mancardi","year":"2009","journal-title":"Biochim.
