Figure 3. Concentric exercise-mediated transcriptomic profile of older muscle. (A) GO terms enriched for genes in older muscle that display increased expression 5 h post-concentric exercise. Red inserts highlight increased expression of GO terms associated with cytoskeletal, cell adhesion and extra-cellular matrix (bottom right) and blood vessel development (top left). (B) GO terms enriched for genes in older muscle that display reduced expression 5 h post-concentric exercise. Blue insert highlights reduced expression of GO term network associated with mitochondrial metabolism. Each node in the network represents a GO term with the size of each node corresponding to the number of genes associated with that term. Significantly enriched terms are coloured yellow with more significant terms a deeper shade.
