The results revealed that (1) h-ERG trafficking was impaired after prolonged period of oxidative stress; (2) chronic oxidative stress induced reciprocal changes of expression between miR-17-5p, along with several other miRNAs sharing the identical seed motif, and the ER stress-related chaperones (Hsp70/Hsc70, CANX, and Galga2), with the former upregulated and the latter downregulated; (3) miR-17-5p targets all these ER stress-related chaperones to cause defective trafficking of h-ERG; (4) Either upregulation of endogenous or application of exogenous miR-17-5p reduced h-ERG current density, and the effects were abolished by miR-17-5p inhibitor; and (5) sequestration of AP1 eliminated the upregulation of miR-17-5p and other members of the seed family, and meanwhile ameliorated impairment of h-ERG trafficking. [score:19]
Furthermore, our study provided preliminary evidence for the role of AP1 in mediating oxidative stress -induced deregulation of miR-17-5p seed family miRNAs: inhibition of AP1 prevented upregulation of these miRNAs and consequently the downregulation of the chaperones was mitigated. [score:10]
To construct reporter vectors bearing miR-17-5p target sites, we synthesized (by Invitrogen) fragments containing the exact target sites for miR-17-5p in the 3’UTRs of Hsp70, Hsc70, CANX, GOLGA2, or the mutated target sites, and inserted these fragments separately into the multiple cloning sites downstream the luciferase gene (HindIII and SpeI sites) in the pMIR-REPORTTM luciferase miRNA expression reporter vector (Ambion, Inc. [score:9]
Collectively, we show here that chronic oxidative stress caused upregulation of the miR-17-5p seed family miRNAs, which in turn target the genes encoding the ER stress-related chaperones to downregulate these proteins, leading to defective trafficking and functional impairment of h-ERG channel proteins. [score:9]
H-ERG trafficking was impaired by H [2]O [2] after 48 h treatment, accompanied by reciprocal changes of expression between miR-17-5p seed miRNAs and several chaperones (Hsp70, Hsc70, CANX, and Golga2), with the former upregulated and the latter downregulated. [score:9]
These findings allowed us to reach the conclusion that deregulation of the miR-17-5p seed family miRNAs can cause severe impairment of h-ERG trafficking through targeting multiple ER stress-related chaperones, and activation of AP1 likely accounts for the deleterious upregulation of these miRNAs, after prolonged oxidative stress. [score:7]
This effect was not seen in cells treated with the mutant miR-17-5p-I. Finally, our whole-cell patch-clamp recordings demonstrated that transfection of miR-17-5p suppressed h-ERG current (I [h-ERG]) in HEK293 cell with stable h-ERG expression, an effect reversed by co-transfection of miR-17-5p-I, but not by the mutant inhibitor (Figure 6). [score:7]
We therefore proposed the following signaling pathway: chronic oxidative stress ― ER stress ― activation/upregulation of AP1 ― upregulation of miR-17-5p/other seed members ― repression of ER stress-related chaperones ― defective trafficking of h-ERG ― h-ERG current reduction ― QT prolongation. [score:7]
This effect was not seen in cells treated with the mutant miR-17-5p-I. Finally, our whole-cell patch-clamp recordings demonstrated that transfection of miR-17-5p suppressed h-ERG current (I [h-ERG]) in HEK293 cell with stable h-ERG expression, an effect reversed by co-transfection of miR-17-5p-I, but not by the mutant inhibitor (Figure 6). [score:7]
Collectively, deregulation of the miR-17-5p seed family miRNAs can cause severe impairment of h-ERG trafficking through targeting multiple ER stress-related chaperones, and activation of AP1 likely accounts for the deleterious upregulation of these miRNAs, in the setting of prolonged duration of oxidative stress. [score:7]

Expression of miR-17-3p was elevated significantly following exposure to quercetin, and bioinformatics identified a consensus binding site for miR-17-3p (bases 61-67 of the 3′UTR sequence) in the human FPN 3′UTR. [score:3]
Finally, we used qPCR to validate the array data to determine whether expression of the miR-17 species was altered following quercetin treatment. [score:3]

hsa-mir-17 belonged to a polycistronic cluster (also containing hsa-mir-18a, hsa-mir-19a, and hsa-mir-20a) residing in a large genomic region highly enriched with TF binding sites, let-7a and let-7f, also likely to be transcriptionally coupled, were also enriched with TFBSs, and mir-7-1 was also found in a large genomic region with high density of TFBSs.
