Abstract
Molecular genetics experiments using gene targeting and transgenic technology demonstrated the importance of alpha-calcium-calmodulin-dependent protein kinase II (alphaCaMKII) in long-term potentiation (LTP) and memory. Little information is available though on how CaMKII activity may be regulated in vivo. We show that estradiol benzoate activates CaMKII in a dose and time-dependent manner in mouse hippocampus after 30 min stimulation. The effect of estrogen is via a very rapid nongenomic mechanism that is blocked in vitro in hippocampal primary neurons by the pure estrogen receptor antagonist, ICI 182,780. These results suggest that estrogen action in the hippocampus is linked to CaMKII activation.Entities:
