P53 inhibition exacerbates late-stage anthracycline cardiotoxicity.
AIMS Doxorubicin (DOX) is an effective anti-cancer therapeutic, but is associated with both acute and late-stage cardiotoxicity. Children are particularly sensitive to DOX-induced heart failure. Here, the impact of p53 inhibition on acute vs. late-stage DOX cardiotoxicity was examined in a juvenile model. METHODS AND RESULTS Two-week-old MHC-CB7 mice (which express dominant-interfering p53 in...
متن کاملAnthracycline Cardiotoxicity
In this issue, Gupta et al describe a novel mechanism, mediated through alterations in the RNA-binding protein QKI (Quaking), responsible for anthracycline-mediated cardiotoxicity. Performing global transcriptional profiling in murine hearts exposed to doxorubicin, they identified 5 differentially expressed RNA-binding proteins: 4 of which were upregulated and 1 QKI which was downregulated. QKI...
متن کاملAnthracycline Cardiotoxicity
Anthracyclines remain an integral part of chemotherapy regimens in many adult and pediatric cancers but cause myocardial damage that may manifest as either subclinical decrements of left ventricular ejection function or overt cardiomyopathy. Anthracycline-related cardiotoxicity is doselimiting, and the risks of congestive heart failure increase with higher cumulative doses, particularly above 5...

متن کاملTargeted expression of cyclin D2 results in cardiomyocyte DNA synthesis and infarct regression in transgenic mice.
Restriction point transit and commitment to a new round of cell division is regulated by the activity of cyclin-dependent kinase 4 and its obligate activating partners, the D-type cyclins. In this study, we examined the ability of D-type cyclins to promote cardiomyocyte cell cycle activity. Adult transgenic mice expressing cyclin D1, D2, or D3 under the regulation of the alpha cardiac myosin he...
