Figure 2. Age-dependent changes in miRNA expression. (A) A Heatmap showing expression patterns of 152 miRNAs that are commonly expressed in WT and eat-2(ad1116) at day 1 (young-adults) and day 8 (aging worms) of adulthood. The miRNAs are grouped into distinct clusters A-G based on the similarity in their expression patterns. (B) A Heatmap comparing the expression of miRNAs in WT, eat-2(ad1116) and daf-2(e1370).
