Recently, both enzymes have been shown to produce hydrogen sulfide and polysulfide. Subcellular fractionation of liver mitochondria revealed that the TST activity ratio of MST-knockout (KO)\/wild-type mice was approximately 2.5; MST activity was detected only in wild-type mice, as expected. The ratio of TST mRNA expression of KO\/wild-type mice, as measured by real-time quantitative polymerase chain reaction analysis, was approximately 3.3. It is concluded that TST is overexpressed in MST-KO mice.<\/jats:p>","DOI":"10.3390\/antiox8050116","type":"journal-article","created":{"date-parts":[[2019,5,2]],"date-time":"2019-05-02T03:15:22Z","timestamp":1556766922000},"page":"116","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Novel Characterization of Antioxidant Enzyme, 3-Mercaptopyruvate Sulfurtransferase-Knockout Mice: Overexpression of the Evolutionarily-Related Enzyme Rhodanese"],"prefix":"10.3390","volume":"8","author":[{"given":"Noriyuki","family":"Nagahara","sequence":"first","affiliation":[{"name":"Isotope Research Laboratory, Nippon Medical School, Tokyo 113-8602, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mio","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kanagawa Children\u2019s Medical Center, Yokohama 232-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yukichi","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kanagawa Children\u2019s Medical Center, Yokohama 232-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takaaki","family":"Ito","sequence":"additional","affiliation":[{"name":"Department of Pathology and Experimental Medicine, Graduate School of Medical Science, Kumamoto University, Kumamoto 860-8556, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"16230","DOI":"10.1074\/jbc.270.27.16230","article-title":"Cytosolic mercaptopyruvate sulfurtransferase is evolutionarily related to mitochondrial rhodanese.
