Expression data from DOX(doxorubicin) -treated wild type or CHIP knockout C57BL/6J mice at day 5

ABSTRACT: The clinical application of doxorubicin as a broad-spectrum anti-tumor antibiotic is limited greatly by its cardiotoxicity. Various mechanisms have been studied, but little is known about whether genes or pathways relevant with energy metabolism contributes to doxorubicin-induced cardiomyopathy or not. We used microarrays to detail the global expression profiling of acute cardiomyopathy induced by doxorubicin in wild type or CHIP knockout C57BL/6J mice and discovered distinct classes of changed genes during this process.

The whole hearts were selected for RNA extraction and hybridization on Affymetrix microarrays at day 5 after a single intraperitoneal injection of doxorubicin at a dose of 15 mg/kg.

Transcriptional analysis of doxorubicin-induced cardiotoxicity

Project description:Doxorubicin (Dox) is an effective chemotherapeutic agent against a broad range of tumors. However, a threshold dose of doxorubicin causes an unacceptably high incidence of heart failure and limits its clinical utility. We have established two models of doxorubicin cardiotoxicity in mice: 1) in an acute model, mice are treated with 15mg/kg of doxorubicin once; 2) in a chronic model, they receive 3mg/kg weekly for the first 12 of a total of 18 weeks. Using echocardiography, we have monitored left ventricular function of the mouse hearts during treatment in chronic model and seen the expected development of dilated cardiomyopathy (DCM). Treated mice showed histological abnormalities similar to those seen in patients with doxorubicin cardiomyopathy. To investigate transcriptional regulation in these models, we used a microarray we generated with over 5000 independent cDNA clones from murine heart and skeletal muscle. We have identified genes that respond to doxorubicin exposure in both model systems, and confirmed these results using real-time PCR. In the acute model, a set of genes is regulated early and rapidly returns to baseline levels, consistent with the half-life of doxorubicin. In the chronic model, which mimics the clinical situation much more closely, we identified dysregulated genes that implicate specific mechanisms of cardiac toxicity and may serve as biomarkers of doxorubicin induced dilated cardiomyopathy.

Detoxifying doxorubicin

Project description:The anthracycline doxorubicin is a highly effective anti-cancer drug associated with severe side effects, including secondary tumors and cardiotoxicity. Doxorubicin induces DNA damage through double-strand breaks (DSBs) and epigenetic or chromatin damage through histone eviction. We examined whether separation of these activities can help to detoxify doxorubicin, while maintaining its chemotherapeutic efficacy. We show that anthracycline variants harboring the histone eviction activity alone remain potent anti-cancer drugs, while greatly alleviating cardiotoxicity and secondary tumor formation. We thus demonstrate that treatment-limited side effects of doxorubicin can be synthesized away, yielding effective chemotherapeutics towards improved and prolonged treatment responses and higher patient quality of life.

Targets of miR-212/132 in doxorubicin-induced cardiotoxicity

Project description:We overexpressed miR-212/132 by AAV9 in mouse model of doxorubicin-induced cardiotoxicity and wanted to identify myocardial targets of miR-212/132 in this model.

mRNA array profiling on human pluripotent stem cell-derived cardiomyocytes exposed to doxorubicin

Project description:Cardiomyocytes derived from human pluripotent stem cells were exposed to the cardiotoxic drug Doxorubicin in order to assess the utility of this cell system as a model for drug-induced cardiotoxicity. Cells are exposed to different concentrations of doxorubicin for up to 48 hours followed by a 12 days recovery period.

Effects on gene expression of doxorubicin in human stem cells-derived cardiomyocytes

Project description:To gain into the molecular mechanisms and pathways involved in doxorubicin induced cardiotoxicity, we performed whole genome transcriptome profiling via RNA-seq in hESCs-derived CMs treated with doxorubicin or vehicle only control. Cells were treated with 0, 1 or 2.5 μM of doxorubicin for 16 hours and RNA was isolated for high throughput sequencing

The Cardiac Endothelial Cell cGAS-STING Pathway Promotes Doxorubicin-Induced Cardiotoxicity via CD38-Mediated NAD Decline and Mitochondrial Dysfunction [human]

Project description:Doxorubicin is an effective chemotherapy drug for treating various types of cancer. However, lethal cardiotoxicity severely limits its clinical use. Recent evidence has indicated that aberrant activation of the cytosolic DNA-sensing cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway plays a critical role in cardiovascular destruction. Here, we investigate the involvement of this mechanism in doxorubicin-induced cardiotoxicity (DIC).

Transcriptomic analysis of folic acid effects in doxorubicin-induced cardiotoxicity

Project description:Doxorubicin (DOXO), a chemotherapeutic drug, is cardiotoxic. We hypothesized that folic acid is an effective therapeutic agent in a mouse model of DOXO-induced cardiotoxicity. We performed genome-wide expression profiling to identify the underlying mechanisms.
