| | Sample_treatment_protocol_ch1 | There was no treatment. Three groups of rats were defined by age and cognitive staus: Young, Aged Unimpaired, and Aged Impaired. Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats. Low scores reflect good performance and aged rats performing within the range of young are designated aged unimpaired (AU) whereas those performing worse than young are considered aged impaired (AI).
| | Sample_growth_protocol_ch1 | Aged, male Long-Evans rats were obtained at 8-9 mo of age from Charles River Laboratories (Raleigh, NC) and housed in a vivarium at The Johns Hopkins University until 24-26 mo of age for the present experiments. Young rats at 6 months of age were tested alongside the aged rats. All rats were individually housed at 25°C and maintained on a 12 hr light/dark cycle. Food and water were provided ad libitum. The rats were examined for health and pathogen-free status throughout the experiments, as well as by necropsies at the time of sacrifice. All procedures were approved by the institutional animal care and use committee in accordance with the National Institutes of Health directive.

| | Sample_extract_protocol_ch1 | All rats were sacrificed two weeks after completion of behavioral testing by rapid decapitation, and brains removed from the skull. The CA1, CA3 and DG regions of the hippocampus were microdissected from the hippocampus and total RNA was extracted by homogenization in Trizol reagent (Invitrogen) followed by application to Qiagen RNeasy columns.

| | Sample_treatment_protocol_ch1 | There was no treatment. Three groups of rats were defined by age and cognitive staus: Young, Aged Unimpaired, and Aged Impaired. Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats. Low scores reflect good performance and aged rats performing within the range of young are designated aged unimpaired (AU) whereas those performing worse than young are considered aged impaired (AI).
| | Sample_growth_protocol_ch1 | Aged, male Long-Evans rats were obtained at 8-9 mo of age from Charles River Laboratories (Raleigh, NC) and housed in a vivarium at The Johns Hopkins University until 24-26 mo of age for the present experiments. Young rats at 6 months of age were tested alongside the aged rats. All rats were individually housed at 25°C and maintained on a 12 hr light/dark cycle. Food and water were provided ad libitum. The rats were examined for health and pathogen-free status throughout the experiments, as well as by necropsies at the time of sacrifice. All procedures were approved by the institutional animal care and use committee in accordance with the National Institutes of Health directive.

| | Sample_treatment_protocol_ch1 | There was no treatment. Three groups of rats were defined by age and cognitive staus: Young, Aged Unimpaired, and Aged Impaired. Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats. Low scores reflect good performance and aged rats performing within the range of young are designated aged unimpaired (AU) whereas those performing worse than young are considered aged impaired (AI).
| | Sample_growth_protocol_ch1 | Aged, male Long-Evans rats were obtained at 8-9 mo of age from Charles River Laboratories (Raleigh, NC) and housed in a vivarium at The Johns Hopkins University until 24-26 mo of age for the present experiments. Young rats at 6 months of age were tested alongside the aged rats. All rats were individually housed at 25°C and maintained on a 12 hr light/dark cycle. Food and water were provided ad libitum. The rats were examined for health and pathogen-free status throughout the experiments, as well as by necropsies at the time of sacrifice. All procedures were approved by the institutional animal care and use committee in accordance with the National Institutes of Health directive.

| | Sample_treatment_protocol_ch1 | There was no treatment. Three groups of rats were defined by age and cognitive staus: Young, Aged Unimpaired, and Aged Impaired. Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats. Low scores reflect good performance and aged rats performing within the range of young are designated aged unimpaired (AU) whereas those performing worse than young are considered aged impaired (AI).
| | Sample_growth_protocol_ch1 | Aged, male Long-Evans rats were obtained at 8-9 mo of age from Charles River Laboratories (Raleigh, NC) and housed in a vivarium at The Johns Hopkins University until 24-26 mo of age for the present experiments. Young rats at 6 months of age were tested alongside the aged rats. All rats were individually housed at 25°C and maintained on a 12 hr light/dark cycle. Food and water were provided ad libitum. The rats were examined for health and pathogen-free status throughout the experiments, as well as by necropsies at the time of sacrifice. All procedures were approved by the institutional animal care and use committee in accordance with the National Institutes of Health directive.

| | Sample_treatment_protocol_ch1 | There was no treatment. Three groups of rats were defined by age and cognitive staus: Young, Aged Unimpaired, and Aged Impaired. Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats. Low scores reflect good performance and aged rats performing within the range of young are designated aged unimpaired (AU) whereas those performing worse than young are considered aged impaired (AI).
| | Sample_growth_protocol_ch1 | Aged, male Long-Evans rats were obtained at 8-9 mo of age from Charles River Laboratories (Raleigh, NC) and housed in a vivarium at The Johns Hopkins University until 24-26 mo of age for the present experiments. Young rats at 6 months of age were tested alongside the aged rats. All rats were individually housed at 25°C and maintained on a 12 hr light/dark cycle. Food and water were provided ad libitum. The rats were examined for health and pathogen-free status throughout the experiments, as well as by necropsies at the time of sacrifice. All procedures were approved by the institutional animal care and use committee in accordance with the National Institutes of Health directive.

Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats.

| | Sample_treatment_protocol_ch1 | There was no treatment. Three groups of rats were defined by age and cognitive staus: Young, Aged Unimpaired, and Aged Impaired. Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats. Low scores reflect good performance and aged rats performing within the range of young are designated aged unimpaired (AU) whereas those performing worse than young are considered aged impaired (AI).
| | Sample_growth_protocol_ch1 | Aged, male Long-Evans rats were obtained at 8-9 mo of age from Charles River Laboratories (Raleigh, NC) and housed in a vivarium at The Johns Hopkins University until 24-26 mo of age for the present experiments. Young rats at 6 months of age were tested alongside the aged rats. All rats were individually housed at 25°C and maintained on a 12 hr light/dark cycle. Food and water were provided ad libitum. The rats were examined for health and pathogen-free status throughout the experiments, as well as by necropsies at the time of sacrifice. All procedures were approved by the institutional animal care and use committee in accordance with the National Institutes of Health directive.

| | Sample_treatment_protocol_ch1 | There was no treatment. Three groups of rats were defined by age and cognitive staus: Young, Aged Unimpaired, and Aged Impaired. Behavioral assessment of memory function in a Morris water maze task was conducted as previously described (Gallagher et al., 1993). A learning index was generated from the proximity of the rat to the escape platform during probe trials interpolated throughout training and was used to define impairment in the rats. Low scores reflect good performance and aged rats performing within the range of young are designated aged unimpaired (AU) whereas those performing worse than young are considered aged impaired (AI).
| | Sample_growth_protocol_ch1 | Aged, male Long-Evans rats were obtained at 8-9 mo of age from Charles River Laboratories (Raleigh, NC) and housed in a vivarium at The Johns Hopkins University until 24-26 mo of age for the present experiments. Young rats at 6 months of age were tested alongside the aged rats. All rats were individually housed at 25°C and maintained on a 12 hr light/dark cycle. Food and water were provided ad libitum. The rats were examined for health and pathogen-free status throughout the experiments, as well as by necropsies at the time of sacrifice. All procedures were approved by the institutional animal care and use committee in accordance with the National Institutes of Health directive.
