Figure 4From: Age and sex differences in kidney microRNA expression during the life span of F344 rats The number of miRNAs exhibiting a sex difference in expression (pairwise t -test, FDR <5%, and fold change ≥1.5) was calculated for each age. Groups of 5-, 6-, and 8-week-old rats exhibited no sex differences in miRNA expression, while 21-week-old rats showed the highest number.Back to article page
