Project description:Many oncology drugs have been found to induce cardiotoxicity in a subset of patients, which significantly limits their clinical use and impedes the benefit of lifesaving anti-cancer treatments. Human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) carry donor-specific genetic information and have been proposed for explore the inter-individual difference in oncology drug-induced cardiotoxicity. Herein, we evaluated the inter- and intra- individual variability of iPSC-CM-related assays and presented a practical approach for using donor-specific iPSC-CMs to predict personalized doxorubicin (DOX)-induced cardiotoxicity (DIC) prior to chemotherapy. Our findings demonstrated that donor-specific iPSC-CMs exhibited greater line-to-line variability than the intra-individual variability in impedance cytotoxicity and transcriptome assays. The variable and dose-dependent cytotoxic responses of iPSC-CMs resembled those observed in clinical practice, and largely replicated the reported mechanisms of DIC. By categorizing iPSC-CMs into DOX-resistant and DOX-sensitive cell lines based on their phenotypic reactions to DOX, we found that the sensitivity of donor-specific iPSC-CMs to DOX may predict in vivo DIC risk. Furthermore, we assessed the limitations of the model for identification of potential genetic/molecular biomarker and pinpointed a differentially expressed gene, DND microRNA-mediated repression inhibitor 1 (DND1), between the DOX-resistant and DOX-sensitive iPSC-CMs. We also discussed the selection of DOX dose and exposure duration for inter-individual variability of DIC assessment. Our results support the utility of donor-specific iPSC-CMs in assessing inter-individual difference and enabling personalized cardiotoxicity prediction. Further studies will encompass a large panel of donor-specific iPSC-CMs to investigate the role of the DND1 and known DIC genetic variants, and to identify potential novel molecular and genetic biomarkers for predicting DOX and other oncology drug-induced cardiotoxicity.

Project description:Phosphodiesterase 10A (PDE10A), by degrading cAMP/cGMP, play critical roles in cardiovascular biology/disease. Cardiotoxicity is a clinical complication of chemotherapy. We aim to determine the role of PDE10A in cancer growth and cardiotoxicity induced by doxorubicin (DOX), a chemotherapy drug. We found that PDE10A deficiency/inhibition alleviated DOX-induced cardiotoxicity in C57Bl/6J mice, including myocardial atrophy, apoptosis, and dysfunction. RNAseq study revealed several PDE10A-regulated signaling associated with DOX-induced cardiotoxicity. In cancer cells, PDE10A inhibition increased the death, decreased the proliferation, and potentiated the effect of DOX in various cancer-cell lines. Importantly, in nude mice with implanted ovarian cancer xenografts, PDE10A inhibition attenuated tumor growth while protected against DOX-induced cardiotoxicity. In isolated cardiomyocytes (CMs), PDE10A contributed to DOX-induced CM death via promoting mitochondrial dysfunction, and to CM atrophy via potentiating foxo3 signaling. Collectively, our study elucidates a novel role for PDE10A in cardiotoxicity and cancer growth in vitro and in vivo, and suggest that PDE10A inhibition may represent a novel strategy in cancer therapy.

Project description:Doxorubicin (Adriamycin) is an anthracycline chemotherapy agent effective in treating a wide range of malignancies1 with a well-established dose-response cardiotoxic side-effect that can lead to heart failure2-4. Even at relatively low cumulative doses of 200–250 mg/m2, the risk of cardiotoxicity is estimated at 7.8% to 8.8%4,5. Doxorubicin-induced cardiotoxicity (DIC) can range from asymptomatic reductions in left ventricular ejection fraction (LVEF) to highly symptomatic heart failure6,7. At present, it is not possible to predict which patients will be affected by DIC or adequately protect patients who are at risk for suffering this devastating side-effect8. Here we demonstrate that patient-specific human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) can recapitulate individual patients’ predilection to DIC at the single cell level. hiPSC-CMs derived from breast cancer patients who suffered clinical DIC are consistently more sensitive to doxorubicin toxicity, demonstrating decreased cell viability, mitochondrial/metabolic function, calcium handling, and antioxidant pathway gene expression, along with increased reactive oxygen species (ROS) production compared to hiPSC-CMs from patients who did not experience DIC. Together, our data indicate that hiPSC-CMs are a suitable platform for identifying and verifying the genetic basis and molecular mechanisms of DIC.

Project description:The anthracycline, doxorubicin (Dox), is widely used in oncology, but it may it may cause a cardiomyopathy which has dismal prognosis and cannot be effectively prevented. The secretome of multipotent human amniotic fluid-derived stem cells (hAFS) has previously been demonstrated to reduce ischemic cardiac damage. Here, it is shown that the hAFS conditioned medium (hAFS-CM) antagonizes senescence and apoptosis of cardiomyocytes and cardiac progenitor cells, two major features of Dox cardiotoxicity. Mechanistic studies with primary mouse neonatal cardiomyocytes reveal that hAFS-CM inhibition of Dox-elicited senescence and apoptosis is paralleled by decreased DNA damage and is associated with nuclear translocation of NF-kB and upregulation of a set of genes controlled by NF-kB, namely Il6 and Cxcl1, which promote cardiomyocyte survival, and Cyp1b1 and Abcb1, which encode for proteins involved in Dox metabolism and efflux, respectively. The PI3K/Akt signaling cascade, upstream of NF-kB, is potently activated by the hAFS-CM and pre-treatment with a PI3K inhibitor abrogates NF-kB accumulation into the nucleus, modulation of its target genes, and prevention of Dox-initiated senescence and apoptosis in response to the hAFS-CM. This work may lay the ground for the development of a stem cell-based paracrine therapy of chemotherapy-related 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. Male C57Bl6 2-mo old mice received DOXO (1x20 mg/kg, ip) or saline (sham). FA (10 mg/d) or placebo (plac) was administered 7d before DOXO administration until the end of the experiment (10d).
