Isolated rat hearts were subjected to aerobic perfusion or I\/Ri control. The effect of simvastatin was assessed in hearts subjected to I\/Ri. We determined cardiac mechanical function, the content of RhoA, phosphorylated myosin light chain subunit 1 (phospho-MYL9), troponin I, MMP-2, and MMP-2 mRNA in the heart homogenates, as well as MMP-2 activity in heart tissue. We showed that treatment with simvastatin caused improvement in the contractile function of the heart subjected to I\/Ri which was accompanied by a decrease of MMP-2 activity in heart tissue along with inhibition of RhoA pathway, expressed in a reduction in both RhoA and its downstream product\u2014phosphorylated myosin light chain (phospho-MYL9) in hearts treated with simvastatin. MMP-2 inactivation is not due to inhibition of MMP-2 m-RNA synthesis caused by inhibition of RhoA\/ROCK pathway and is due, at least in part, to the direct drug action. The protective effect of simvastatin on systolic function in the acute ischemia-reperfusion model does not appear to be related to reduced MMP-2 activation, but other mechanisms related with the inhibition RhoA\/ROCK pathway.<\/jats:p>","DOI":"10.3390\/biom12091291","type":"journal-article","created":{"date-parts":[[2022,9,13]],"date-time":"2022-09-13T21:06:52Z","timestamp":1663103212000},"page":"1291","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The Protective Effect of Simvastatin on the Systolic Function of the Heart in the Model of Acute Ischemia and Reperfusion Is Due to Inhibition of the RhoA Pathway and Independent of Reduction of MMP-2 Activity"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1641-8025","authenticated-orcid":false,"given":"Monika","family":"Skrzypiec-Spring","sequence":"first","affiliation":[{"name":"Department of Pharmacology, Wroc\u0142aw Medical University, 50-345 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agnieszka","family":"Sapa-Wojciechowska","sequence":"additional","affiliation":[{"name":"Department of Clinical Chemistry, Wroc\u0142aw Medical University, 50-556 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alina","family":"Rak-Pasikowska","sequence":"additional","affiliation":[{"name":"Department of Clinical Chemistry, Wroc\u0142aw Medical University, 50-556 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7787-9952","authenticated-orcid":false,"given":"Maciej","family":"Kaczorowski","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Pathology, Wroc\u0142aw Medical University, 50-556 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iwona","family":"Bil-Lula","sequence":"additional","affiliation":[{"name":"Department of Clinical Chemistry, Wroc\u0142aw Medical University, 50-556 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Agnieszka","family":"Ha\u0142o\u0144","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Pathology, Wroc\u0142aw Medical University, 50-556 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam","family":"Szel\u0105g","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Wroc\u0142aw Medical University, 50-345 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"112","DOI":"10.1016\/j.tcm.2012.03.008","article-title":"Cardiac sarcomeric proteins: Novel intracellular targets of matrix metalloproteinase-2 in heart disease","volume":"21","author":"Ali","year":"2011","journal-title":"Trends Cardiovasc.
