From: Sex and age differences in the expression of liver microRNAs during the life span of F344 rats
PCA plot of differentially expressed miRNA profiles of 88 rat liver samples. Normalized log2 intensity values for 214 miRNAs that were differentially expressed by age and/or sex in livers of rats of nine ages and both sexes are plotted. Each sphere represents the composite DEM profile from a single animal. Colors represent age groups. Black vertices indicate female animals; males have none
