Ontology analysis of apoptotic genes expressed in healthy gingival tissues from adult vs. aged non-human primates. Comparison of apoptosis gene expression was done between healthy gingival tissues from young vs. aged animals as described in MATERIALS & METHODS. Genes shown in red are over-expressed, and genes shown in yellow are under-expressed in adult gingival tissue compared with aged gingival tissue. Expression of genes shown in purple was unchanged at p ≤ 0.05 significance. +p = phosphorylation event; -p = dephosphorylation event.
