Quantitative RT-PCR analyses of miRNAs deregulated during UPR in H9c2 cells. H9c2 cardiomyocytes were either untreated (Control) or treated with (1.0 μM) Tg and (1.0 μg/ml) Tm for 24 hours. The expression level of indicated miRNAs was quantified by qRT-PCR, normalizing against snoRNA. Error bars represent mean ± S.D. from three independent experiments performed in triplicate. (* P < 0.05, two-tailed unpaired t-test compared with untreated cells).
