Study Overview
Brief Summary
This study aims to assess the cardioprotective effect of melatonin and vitamin D in breast cancer patients who receive doxorubicin.
Detailed Description
Doxorubicin is one of the most potent chemotherapeutic agents and is widely used for the treatment of various cancers and hematological malignancies . Although Doxorubicin has a potential beneficial effect in cancer treatment, its dose-dependent cardio toxicity is considered a major challenge.
Doxorubicin is known to generate free radicals either by redox cycling between a semiquinone form and a quinone form or by forming a Doxorubicin-Fe3+ complex . In both pathways, molecular oxygen is reduced to superoxide ion , which is converted to other forms of reactive oxygen species such as hydrogen peroxide and hydroxyl radical . These free radicals could then cause membrane and macromolecule damage, both of which lead to injury to the heart, an organ that has a relatively low level of antioxidant enzymes such as superoxide dismutase and catalase .
Furthermore, it was revealed that Doxorubicin may enhance the death of cardiomyocytes by affecting the tumor necrosis factor signaling pathway via increasing the expression and levels of inflammatory genes interleukin and interleukin -6 .
To alleviate DOX-induced toxicity, researchers have tested a number of strategies, including the administration of antioxidants and/or antiapoptotic agents, in both in vitro and in vivo models of Doxorubicin induced cytotoxicity, but most of these trials have failed to translate into clinical benefits . As a result, there are no effective approaches for alleviating Doxorubicin induced cytotoxicity despite intensive research over recent decades .
Melatonin is a natural hormone that is primarily secreted by the pineal gland and functions as a major regulator of circadian rhythms in humans . Melatonin also plays a variety of biological roles as a modulator of mood, sexual behavior and sleep; low levels or a deficiency of melatonin are also associated with Parkinson's disease, Alzheimer's disease, epilepsy, ischemic injury, diabetes, and even cancer .
