Portulaca oleracea protects H9c2 cardiomyocytes against doxorubicin-induced toxicity via regulation of oxidative stress and apoptosis
Abstract Background and Objectives: Doxorubicin as an effective chemotherapeutic agent is frequently used in various cancers. Nowadays, the application of doxorubicin is limited due to its cardiotoxic effects. The important mechanism which is involved in the cardiac injury of doxorubicin is the generation of reactive oxygen species; therefore antioxidant compounds may reduce cardiotoxicity. ...
متن کاملERKs/p53 signal transduction pathway is involved in doxorubicin-induced apoptosis in H9c2 cells and cardiomyocytes.
The cardiotoxic effects of doxorubicin, a potent chemotherapeutic agent, have been linked to DNA damage, oxidative mitochondrial damage, and nuclear translocation of p53, but the exact molecular mechanisms causing p53 transactivation and doxorubicin-induced cardiomyopathy are not clear. The present study was carried out to determine whether extracellular signal-regulated kinases (ERKs), which a...
متن کاملNitrone spin traps and a nitroxide antioxidant inhibit a common pathway of thymocyte apoptosis.
Oxidative stress has recently been suggested to be a mediator of apoptotic cell death [Buttke and Sandstrom (1994) Immunology Today 15, 7-10], although evidence that this phenomenon is a widespread component of apoptosis is lacking. When rat thymocytes were exposed to the glucocorticoid methylprednisolone (MPS), a progressive increase in intracellular peroxides and a decrease in glutathione (GS...
متن کاملComparison of BAX and Bcl-2 Expression During Human Embryonic Stem Cell Differentiation into Cardiomyocytes and Doxorubicin-induced Apoptosis
Back ground: Although the cell differentiation is an inseparable part of development in multicellular organisms, the regulating molecular pathway of it still is not fully defined. In the other hand, apoptosis is a fundamental physiological process which plays an essential role in a variety of biological events during development. Moreover, recent studies have found that apoptosis shows several ...
متن کاملOverexpression of angiopoietin-1 reduces doxorubicin-induced apoptosis in cardiomyocytes
Doxorubicin (Dox) is a major anticancer chemotherapeutic agent. However, it causes cardiomyopathy due to the side effect of cardiomyocyte apoptosis. We have previously reported that angiopoietin-1 significantly reduced myocardial infarction after ischemic injury and protected cardiomyocytes from oxidative stress-induced apoptosis. It is hypothesized that angiopoietin-1 may protect cardiomyocyte...
