HDAC3-mediated regulation of the circadian gene Per1 contributes to age-related impairments in hippocampal memory and synaptic plasticity

We performed an RNA Sequencing experiment on dorsal hippocampal tissue from six groups of animals: Aging (18-20-month-old) HDAC3flox/flox homecage (H3F-HC); Aging (18-20-month-old) HDAC3flox/flox 60min post training (H3F-BV); Aging (18-20-month-old) wildtype homecage (OWT-HC); Aging (18-20-month-old) wildtype 60min post training (OWT-BV); Young (2-4-month-old) wildtype homecage (YWT-HC); Young (2-4-month-old) wildtype 60min post training (YWT-BV). Homecage animals were sacrificed directly from the animal's cage. Behavior animals were sacrificed sixty minutes following a 10min Object Location Memory training session. Overall design: The objective of this study was to examine activity regulated gene expression in the dorsal hippocampus following a learning event in young (~3-m.o.) and old (~18-m.o.) wildtype and HDAC3flox/flox mutant mice. HDAC3 was deleted in dorsal hippocampus tissue of HDAC3flox/flox mice using AAV-CaMKII-Cre before behavior.
