The cyclic voltammetry of both bulk manganese sulfate (BMS) and nano manganese sulfate (NMS) were studied using 0.1M KCl supporting electrolyte and glassy carbon working electrode. The redox behavior for both bulk (BMS) and MnSO4 (NMS) sulfate was studied voltammetrically in presence and absence of Doxorubicin (DR) using three electrodes system, silver- silver chloride (Ag/AgCl), pla...

Abstract Background Activation of autophagy flux contributed to resistance breast cancer (BC) cells current chemotherapeutic drugs, which seriously limited their therapeutic efficacy and facilitated BC recurrence in clinic. However, the detailed mechanisms are still not fully understood. In present study, we identified that inactivation AMPK-ULK1 signaling cascade mediated protective sensitized...

The precise molecular events involved in the development of drug resistance (DR) remain largely unknown. Raf is an intermediate in the signal transduction cascades initiated by growth factors. The hypothesis behind the following studies is that deregulated Raf-1 expression plays a role in the development of drug resistance. A positive correlation was observed between increased Raf-1 activity an...

Anticancer drug resistance is a multifactorial process that includes acquired and de novo drug resistances. Acquired resistance develops during treatment, while de novo resistance is the primary way for tumor cells to escape chemotherapy. Tumor microenvironment has been recently shown to be one of the important factors contributing to de novo resistance and called environment-mediated drug resi...

introduction: doxorubicin is frequently used for treatment of several types of cancer. doxorubicin cardiac toxicity has limited the use of this drug. corticosteroids may prevent doxorubicin induced cardiotoxicity. therefore the aim of this study was to evaluate mouse embryonic stem cells derived cardiomyocytes as a model to evaluate the effect of doxorubicin and dexamethasone. methods: mouse em...

We read with great interest the Highlight Review by Dr C GruÈ ndker entitled `Cytotoxic luteinizing hormonereleasing hormone conjugates and their use in gynecological cancer therapy' in the European Journal of Endocrinology (1). This excellent article provides a detailed description of recent developments in the field of targeted chemotherapy based on luteinizing hormone-releasing hormone (LH-R...

Introduction: Doxorubicin is frequently used for treatment of several types of cancer. Doxorubicin cardiac toxicity has limited the use of this drug. Corticosteroids may prevent doxorubicin induced cardiotoxicity. Therefore the aim of this study was to evaluate mouse embryonic stem cells derived cardiomyocytes as a model to evaluate the effect of Doxorubicin and dexamethasone. Methods: Mouse ...

objective(s):berberine, a naturally occurring isoquinoline alkaloid, has shown antitumor properties in some in vitro systems. but the effect of berberine on breast cancer has not yet been completely studied. in this study, we evaluated anticancer properties of berberine in comparison to doxorubicin. materials and methods: the antiproliferative effects of berberine and doxorubicin alone and in c...
