We hypothesized that in this condition the composition of the myocardial proteins of rats was altered. To identify yet unknown quantitative and qualitative differences in myocardial proteins in renovascular hypertensive heart disease, we analyzed protein patterns by computer\u2010assisted two\u2010dimensional polyacrylamide large gel electrophoresis. Renovascular hypertension was induced by placing a silver clip on the left renal artery in 9\u2010week\u2010old rat siblings. Sham\u2010operated animals served as controls. Systolic blood pressure (197 \u00b1 19 mm Hg) and heart\/body weight ratios (0.36 \u00b1 0.04%) were significantly increased in the hypertensive animals. Twenty protein patterns from the left ventricle of five hypertensive and five control rats were compared. The molecular mass and isoelectric point (p<jats:italic>I<\/jats:italic>) of proteins spots ranging from 13 to 100 kDa and from 4.5 to 8.5, respectively, were determined using marker proteins. In total, 761 \u00b1 88 protein spots were resolved in all twenty gels. For the quantitative data analysis a univariate (Mann\u2010Whitney test) as well as a multi\u2010variate statistical approach (correspondence analysis) were applied. Only one myocardial protein spot (molecular mass = 41.3 kDa; p<jats:italic>I<\/jats:italic> = 6.3) was decreased by more than twofold (<jats:italic>p<\/jats:italic> &lt; 0.05) in renovascular hypertension. The vast majority of spots did not indicate a significant alteration of intensity. Left ventricular hypertrophy in early renovascular hypertension induces a form of myocardial hypertrophy that conserves the naturally occurring protein expression pattern.<\/jats:p>","DOI":"10.1002\/elps.1150191124","type":"journal-article","created":{"date-parts":[[2005,5,28]],"date-time":"2005-05-28T12:25:42Z","timestamp":1117283142000},"page":"2043-2050","source":"Crossref","is-referenced-by-count":12,"title":["Effects of renovascular hypertension on myocardial protein patterns: Analysis by computer\u2010assisted two\u2010dimensional gel electrophoresis"],"prefix":"10.1002","volume":"19","author":[{"given":"Klaus\u2010Peter","family":"Plei\u00dfner","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vera","family":"Regitz\u2010Zagrosek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernd","family":"Kr\u00fcdewagen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J\u00f6rg","family":"Trenkner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Berthold","family":"Hocher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eckart","family":"Fleck","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,4,14]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.73.3.439"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.92.9.2385"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/elps.1150181504"},{"key":"e_1_2_1_5_2","doi-asserted-by":"crossref","first-page":"1513","DOI":"10.1152\/ajplegacy.1973.225.6.1513","volume":"225","author":"Leenen F.
