Stroke is one of the most common, and damaging, neurological afflictions. Stroke causes widespread and variable chronic effects, due to the limited regenerative ability of the adult brain. Altered gene expression induces neuronal changes necessary for plasticity-dependent recovery, effects which can be enhanced by growth hormone-based pharmaceuticals. These processes are driven by alterations in the informational capacity of the genome – changes driven by epigenetic regulators. Following experimental strokes, and treatment with EGF and EPO, this study shows that two epigenetic regulatory mechanisms, DNA methylation and microRNA regulation, are significantly altered, both in treated and untreated animals. Specifically, treatment induces a net global suppression of miRNA activity, which appears to modify the physical behaviour of neurons in domains ranging from plasticity and memory formation, growth and replication, and potentially even to neurological disease signalling. The confirmation of epigenetic alterations following a stroke indicates a future role for epigenetic neuro-pharmacology in stroke management. / x, [99] leaves : ill. (some col.) ; 29 cm
