BACKGROUND Bacterial infection has been discussed as a potential etiologic factor in the pathophysiology of coronary heart disease (CHD). This study analyzes molecular phylogenies to systematically explore the presence, frequency, and diversity of bacteria in atherosclerotic lesions in patients with CHD. METHODS AND RESULTS We investigated 16S rDNA(More)
An alternative transcript of the rat renin gene was recently characterized in the adrenal gland, in addition to the known messenger RNA (mRNA) coding for preprorenin. In the alternative transcript, exon 1 is replaced by exon 1A, a domain originating in intron 1. The reading frame of this mRNA, termed exon 1A-renin transcript, codes for a truncated prorenin(More)
The effector hormone of the renin-angiotensin system, angiotensin II, plays a major role in cardiovascular regulation. In rats, both angiotensin receptor subtypes, AT(1) and AT(2), are up-regulated after myocardial infarction but previous studies failed to identify the cell types which express the AT(2) receptor in the heart. To address this question we(More)
The model of streptozotocin (STZ)-induced diabetes in Wistar rats was used to study the expression of osteopontin during development of diabetic nephropathy. Diabetes was confirmed by serum glucose levels exceeding 16 mmol/l during the experimental period of 12 weeks. During this period of time, diabetic nephropathy developed, as characterized by a reduced(More)
The renal kallikrein-kinin system (KKS) was studied in pair-fed streptozotocin (STZ)-induced diabetic rats and compared with age-matched controls. Twelve weeks after STZ injection, rats were normotensive, showed hyperglycemia, proteinuria, polydipsia and reduced glomerular filtration rate (GFR) and body weight. The activities of urinary prekallikrein (PKLK)(More)
OBJECTIVE We investigated the effect of chronic treatment with the new Na(+)/H(+)-exchange inhibitor, cariporide, on cardiac function and remodelling 6 weeks after myocardial infarction (MI) in rats. METHODS Treatment with cariporide was commenced either 1 week pre or 30 min, 3 h, 24 h or 7 days after ligation of the left ventricular artery and was(More)
OBJECTIVE We have reported that bradykinin (BK) excretion is increased in severely diabetic rats, independent of the activity of the main renal kinin-forming enzyme, true kallikrein (KLK). To further investigate the relationship between renal BK excretion and renal KLK in diabetes we studied the regulation of the renal kallikrein-like gene, rat kallikrein 7(More)
A reduction of renal kallikrein has been found in non-insulin-treated diabetic individuals, suggesting that an impaired renal kallikrein-kinin system (KKS) contributes to the development of diabetic nephropathy. We analyzed relevant components of the renal KKS in non-insulin-treated streptozotocin (STZ)-induced diabetic rats. Twelve weeks after a single(More)
Cardiac remodeling after myocardial infarction is associated with impaired ventricular function and heart failure and has important implications for survival. The purpose of the present study was to assess the effects of chronic treatment with a novel angiotensin AT(1) receptor antagonist 2-butyl-4-(methylthio-)-1-[[2'[[[(propylamino)carbonyl]amino]sulfonyl(More)
The AT2 receptor regulates several functions of nerve cells, e.g., ionic fluxes, cell differentiation, and axonal regeneration, but also modulates programmed cell death. We tested the hypothesis that angiotensin II (ANG II) via its AT2 receptor not only promotes regeneration but also functional recovery after sciatic nerve crush in adult rats. ANG II(More)
