The antioxidant quercetin protects HL-60 cells with high myeloperoxidase activity against pro-oxidative and apoptotic effects of etoposide.

چکیده
The protective action of quercetin against the pro-oxidant and apoptotic effect of etoposide was investigated in HL-60 cells with a high level of myeloperoxidase (MPO) activity and in cells treated with MPO inhibitor, 4-aminobenzoic acid hydrazide (ABAH). Quercetin significantly protected MPO-rich cells against the pro-oxidative (p<0.05) and apoptotic (p<0.05) effects of etoposide. Pre-treatment with ABAH abolished this protective influence of quercetin on apoptosis induced by etoposide but actually enhanced the action effect of quercetin against etoposide-generated reactive oxygen species (ROS) level by this cytostatic drug. Thus quercetin can protect HL-60 cells against the pro-oxidative activity of etoposide regardless of MPO activity.

Pro-oxidant and antioxidant mechanisms of etoposide in HL-60 cells: role of myeloperoxidase.
Etoposide is an effective anticancer agent whose antitumor activity is associated with its phenolic E-ring, which can participate in intracellular redox cycling reactions. Myeloperoxidase (MPO)-catalyzed one-electron oxidation of the etoposide phenolic ring and/or interaction of this phenolic moiety with reactive radicals yields its phenoxyl radical, whose reactivity may determine the pro- or a...

متن کاملPortulaca 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 کاملEffects of hydrogen peroxide-induced oxidative stress on the pattern of pro-apoptotic and anti-apoptotic genes expression during PC12 cells differentiation
Background and Objective: In neurodegenerative disorders, oxidative stress mediated by reactive oxygen species is strongly associated with increased neuronal damages that lead to apoptosis. Pro-apoptotic and anti-apoptotic gene expressions were changed during cell differentiation that affect cell viability and differentiation. This study was conducted to determine the effects of hydrogen peroxi...
