Tier III GS137396 • Differential Expression in the hippocampus 1 hour after fear conditioning with 3-month-old C57BL/6 mice.

DESCRIPTION:

In 3-month-old C57BL/6J mice, 2229 genes (1980 up-regulated vs. 449 down-regulated) were differentially expressed 1 hour after fear conditioning when compared with the age-matched control group in the hippocampus. False Discovery rate (FDR) < 5%, fold change log2 ≥ 1.

TITLE:

Altered histone acetylation is associated with age-dependent memory impairment in mice.

JOURNAL:

Science (New York, N.Y.) May 2010, Vol 328, pp. 753-6

ABSTRACT:

As the human life span increases, the number of people suffering from cognitive decline is rising dramatically. The mechanisms underlying age-associated memory impairment are, however, not understood. Here we show that memory disturbances in the aging brain of the mouse are associated with altered hippocampal chromatin plasticity. During learning, aged mice display a specific deregulation of histone H4 lysine 12 (H4K12) acetylation and fail to initiate a hippocampal gene expression program associated with memory consolidation. Restoration of physiological H4K12 acetylation reinstates the expression of learning-induced genes and leads to the recovery of cognitive abilities. Our data suggest that deregulated H4K12 acetylation may represent an early biomarker of an impaired genome-environment interaction in the aging mouse brain. PUBMED: 20448184
