Identification of novel miRNAs. (a) Secondary structure prediction of highly expressed novel miRNAs using RNA-fold. (b) Detection of novel miRNAs through Real-time PCR in normoxic and hypoxic samples. The graphical data points in b represent mean ± S.D. of at least three independent experiments. (*P > 0.01 and < 0.05; **P < 0.01). Error bars denote ± S. D.
