As miR-532-3p is able to suppress ARC expression, we wondered whether miR-532-3p regulated DOX sensitivity in cardiomyocytes by targeting ARC. [score:8]
Taken together, we report here that the upregulated expression of miR-532-3p in cardiomyocytes exposed to DOX in vitro and in vivo is involved in DOX cardiotoxicity by targeting ARC. [score:8]
We found that miR-532-3p was upregulated and ARC was downregulated in cardiomyocytes administered with DOX. [score:7]
Enforced expression of ARC showed a strong inhibitory effect on mitochondrial fission (Figure 6a) and cell death (Figure 6b) in the presence of miR-532-3p. [score:5]
Reduced endogenous expression level of miR-532-3p inhibited DOX -induced mitochondrial fission and cell death. [score:5]
Further, we used the luciferase assay system to test whether miR-532-3p can influence the expression of ARC by directly targeting ARC 3′UTR (Supplementary Figure S4d). [score:5]
Chemically modified antisense oligonucleotides (antagomirs) were used to inhibit endogenous miR-532-3p expression. [score:5]
Knockdown of ARC attenuated this inhibitory effect on mitochondrial fission (Figure 6c) and cell death (Figure 6d) in the presence of miR-532-3p antagomir. [score:4]
Thus our data indicate that miR-532-3p is able to target ARC directly in DOX cardiotoxicity. [score:4]
In this study, we reveal that miR-532-3p is upregulated in cardiomyocytes administered with DOX. [score:4]
Our results suggested that enforced expression of ARC or knockdown miR-532-3p cannot completely reverse the DOX effect. [score:4]
Therefore, the development of new therapeutic strategies based on ARC, such as delivery of nucleotides that inhibit miR-532-3p, is promising for overcoming the cardiotoxicity of chemotherapy for cancer therapy. [score:4]
The expression levels of miR-532-3p were increased in DOX -treated cardiomyocytes (Figure 4b) and in mice hearts (Figure 4c) exposed to DOX. [score:3]

When we enforced the expression of miR-532-3p in cardiomyocytes, the mitochondrial fission and death cells were significantly increased in response to the low-dose DOX (0.2  μM) treatment (Figures 5c and d). [score:3]
Overexpression of miR-532-3p sensitized low-dose DOX -induced mitochondrial fission and cell death. [score:3]
These results suggest that inhibition of miR-532-3p may be a novel strategy to conquer cardiotoxicity and not disturb chemotherapeutic effect for cancer patients. [score:3]
Overexpression of miR-532-3p had no significant effect on cell death in response to the low-dose DOX (0.2  μM) treatment (Figure 6e). [score:3]

MiR-532-3p participates in the regulation of ARC expression. [score:3]
In the present study, we have revealed for the first time that miR-532-3p -mediated suppression of ARC is a substantial causal mechanism of DOX -induced cardiac toxicity. [score:3]
Overexpression of miR-532-3p led to an obvious reduction of ARC mRNA and protein levels in cardiomyocytes (Figure 4d). [score:3]
Expression levels of miR-532-3p were not changed in Hela (Figure 7b), SGC-7901 (Figure 7c), SW-480 (Supplementary Figure S5a) and HepG-2 (Supplementary Figure S5b) cells administered with DOX. [score:3]
Knockdown miR-532-3p had no significant effect on cell death induced by DOX in these cancer cells (Figures 7d and e and Supplementary Figures S5c and d). [score:2]
Besides, we generated a mutated luciferase construct, ARC 3′UTR-Mut, and mutations were introduced into the miR-532-3p -binding site of ARC 3′UTR. [score:2]
Taken together, these results suggest that miR-532-3p regulates mitochondrial fission and apoptosis during DOX cardiotoxicity. [score:2]
MiR-532-3p sensitized cells to DOX -induced mitochondrial fission and apoptosis by targeting ARC. [score:2]
But, in cancer cells, the expression levels of miR-532-3p are low compared with cardiomyocytes and do not change in response to DOX. [score:2]
