Microarray analysis of miRNA expression in the chorioamniotic membranes between preterm labor (PTL) and term no labor (TNL) cases. (A) An unsupervised analysis based on principal component analysis shows segregation of two a priori known groups of samples. (B) A heat map showing the log ratios of the 38 differentially expressed miRNAs between TNL and PTL cases. The chorioamniotic membranes at term without labor have decreased expression of 28 miRNAs and increased expression of 10 miRNAs. (p < 0.05). Grey boxes represent missing values.
