Pravastatin attenuates isoprenaline induced cardiac fibrosis in a mouse model.
We investigated the effects of pravastatin (PRAVA) on isoprenaline (ISP) induced cardiac fibrosis using four groups of mice: untreated control, PRAVA, ISP, ISP + PRAVA groups. ISP, 20 mg/kg, was administered subcutaneously daily for 14 days. PRAVA, 20 mg/kg, was administered orally daily for 14 days. Mice were sacrificed on day15 and heart and blood samples were collected to investigate cardiac injury markers. The mean body weight for the ISP group on day 15 was decreased significantly compared to day 0; PRAVA increased the mean body weight slightly on day 15 of treatment compared to day 0. The heart:body weight ratio was increased in the ISP group compared to the control group, but the ratio was returned to near control ratio in the PRAVA + ISP group. The serum creatine kinase-myocardial band (CK-MB) level was reduced significantly in the PRAVA + ISP group compared to the ISP group. Serum triglyceride level was decreased significantly in ISP + PRAVA group compared to the ISP group. PRAVA administration significantly reduced tissue collagen I and III levels in the ISP + PRAVA group compared to the ISP group. Lipid oxidation was decreased and reduced glutathione activity was increased in the PRAVA + ISP group compared to the ISP group. IL-6, α-SMA, CTGF, TGF-β and SMAD-3 gene expressions were decreased in the PRAVA + ISP group compared to the ISP group. We found fewer inflammatory cells and less fibrosis in heart tissue in the PRAVA + ISP group compared to the ISP group. PRAVA decreased ISP induced cardiac fibrosis by reducing oxidative stress, collagen deposition and inflammation, as well as by decreasing expression of TGF-β, SMAD-3 and CTGF genes.
期刊介绍：
Biotechnic & Histochemistry (formerly Stain technology) is the
official publication of the Biological Stain Commission. The journal has been in continuous publication since 1926.
Biotechnic & Histochemistry is an interdisciplinary journal that embraces all aspects of techniques for visualizing biological processes and entities in cells, tissues and organisms; papers that describe experimental work that employs such investigative methods are appropriate for publication as well.
Papers concerning topics as diverse as applications of histochemistry, immunohistochemistry, in situ hybridization, cytochemical probes, autoradiography, light and electron microscopy, tissue culture, in vivo and in vitro studies, image analysis, cytogenetics, automation or computerization of investigative procedures and other investigative approaches are appropriate for publication regardless of their length. Letters to the Editor and review articles concerning topics of special and current interest also are welcome.
