Abstract

Rationale: RBPs (RNA-binding proteins) have been described to be expressed and regulated in various organs including the heart. Little is known about the role of RBPs in heart failure induced by the chemotherapy drug doxorubicin and their interaction with circular RNAs. Objective: We aimed to identify key RBPs involved in doxorubicin-mediated heart failure and to elucidate their function. Methods and Results: Global transcriptome profiling from murine myocardium exposed to doxorubicin identified 5 differentially expressed RBPs. Expression of the RBP QKI (Quaking) in response to doxorubicin was strongly downregulated in rodent cardiomyocytes and human induced pluripotent stem cell–derived cardiomyocytes in vitro and in vivo in mice. Knockdown of Qki in primary cardiomyocytes increased apoptosis and atrophy after treatment with doxorubicin, whereas lentiviral mediated overexpression of Qki5 inhibited the doxorubicin-induced apoptosis in cardiomyocytes. In vivo, AAV9 (adeno-associated virus serotype 9)–mediated cardiac overexpression of Qki5 prevented cardiac apoptosis and cardiac atrophy induced by doxorubicin and improved cardiac function. Mechanistically, by lentiviral-based overexpression and CRISPR/Cas9-mediated silencing of Qki5 , we identified regulated expression of specific circular RNAs derived from Ttn (Titin), Fhod3 (Formin homology 2 domain containing 3), and Strn3 (Striatin, calmodulin-binding protein 3). Moreover, inhibition of Ttn -derived circular RNA increased the susceptibility of cardiomyocytes to doxorubicin. Conclusions: We here show that overexpression of Qki5 strongly attenuates the toxic effect of doxorubicin via regulating a set of circular RNAs. Qki5 is, thus, an interesting target molecule to combat doxorubicin-induced cardiotoxicity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
