Validation of DNA microarray-based miRNA detection in human cells. Mature and precursor miRNA detection in HeLa cells by DNA microarray, validation of array signals by comparison to qRT-PCR data and/or comparison to literature data for mature miRNAs. The presence of individual miRNAs (Figure 7) was determined based on array signal intensity (threshold 190 a.u., according to Figure 3(a)) or qRT-PCR Ct values equal or below a threshold Ct value of 34.65 (corresponding to 2.4 × 10² copies).
