Hyperhomocysteinemia was induced by intragastric administration of DL-homocysteine thiolactone. Total proteolytic activity was measured using casein as a substrate. To determine the activity of metal-dependent and serine proteases, ethylenediaminetetraacetic acid, and phenylmethylsulfonyl fluoride were used. The level of matrix metalloproteinases, tissue inhibitor of metalloproteinases-1, and cytokines was studied by enzyme-linked immunosorbent assay.\nResults: It was found an increase in the total proteolytic activity in the heart of young, adult, and old animals. In addition, the redistribution of proteolytic activity was revealed \u2013 the portion of metal-dependent enzymes increased in all groups while the percentage of serine proteases decreased in the old animals with hyperhomocysteinemia. The state of mild inflammation, evidenced by the increased level of some pro-inflammatory cytokines, was found in the heart of young and old animals with hyperhomocysteinemia.\nConclusions: The pathogenesis of hyperhomocysteinemia is accompanied by a change in the proteolytic activity in the heart as well as a change in the cytokine profile.<\/jats:p>","DOI":"10.36740\/wlek202204115","type":"journal-article","created":{"date-parts":[[2022,5,25]],"date-time":"2022-05-25T12:45:09Z","timestamp":1653482709000},"page":"831-835","source":"Crossref","is-referenced-by-count":3,"title":["PROTEOLYTIC ACTIVITY IN THE HEART OF RATS WITH HYPERHOMOCYSTEINEMIA"],"prefix":"10.36740","volume":"75","author":[{"given":"Nataliia","family":"Raksha","sequence":"first","affiliation":[{"name":"TARAS SHEVCHENKO NATIONAL UNIVERSITY OF KYIV, KYIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oleksandr","family":"Maievskyi","sequence":"additional","affiliation":[{"name":"TARAS SHEVCHENKO NATIONAL UNIVERSITY OF KYIV, KYIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iryna","family":"Dzevulska","sequence":"additional","affiliation":[{"name":"BOGOMOLETS NATIONAL MEDICAL UNIVERSITY, RYIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rostyslav","family":"Kaminsky","sequence":"additional","affiliation":[{"name":"BOGOMOLETS NATIONAL MEDICAL UNIVERSITY, RYIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inga","family":"Samborska","sequence":"additional","affiliation":[{"name":"NATIONAL PIROGOV MEMORIAL MEDICAL UNIVERSITY OF VINNYTSIA, VINNYTSIA, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olexiy","family":"Savchuk","sequence":"additional","affiliation":[{"name":"TARAS SHEVCHENKO NATIONAL UNIVERSITY OF KYIV, KYIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u041eleksandr","family":"Kovalchuk","sequence":"additional","affiliation":[{"name":"TARAS SHEVCHENKO NATIONAL UNIVERSITY OF KYIV, KYIV, UKRAINE"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22436","published-online":{"date-parts":[[2022]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"1.
