Analysis of miRNA expression between newborn and adult groups. A Principal component analysis of miRNA expression between newborn and adult groups. The horizontal coordinate is the first principal component and the vertical coordinate is the second principal component. Different shapes in the figure indicate different samples, and different colors indicate different groupings. B Correlation cluster analysis between samples. The higher the correlation between individuals in fig. 3B, the closer the background color. C Grouped clustering analysis based on miRNA expression patterns. The gray line shows the expression pattern of miRNAs in each cluster, and the blue line indicates the average of expression of all genes in the cluster in the samples. D The distribution of all identified miRNAs across various chromosomes was quantified based on their fold change in expression levels
