caloric restriction

(Submitter supplied) Mice were killed between 24 to 26 months of age, tissues removed, rapidly frozen on dry ice, and stored in liquid nitrogen. Total liver RNA was isolated from frozen tissue as described (T. Tsuchiya, J.M. Dhahbi, X. Cui, P.L. Mote, A. Bartke, S.R. Spindler, Physiological Genomics, Submitted). mRNA levels were measured using the Affymetrix mouse U74Av2 array according to standard protocols. After hybridization, arrays were scanned using a Hewlett-Packard GeneArray Scanner. more...

Plane of nutrition prepartum and bovine hepatic gene expression profiles

(Submitter supplied) Cows were selected from two groups of 12 cows enrolled in a large experiment to assess the effects of ad libitum or restricted intake of moderate-energy diets during the entire dry period on pre-partum metabolism and post-partum metabolism and performance. A corn silage-based diet (26% of diet dry matter) providing 1.59 Mcal/kg during the far-off dry period (first 5 wk of an 8-wk dry period) or providing 1.61 Mcal/kg during the close-up dry period (last 3 wk of the dry period) was fed for ad libitum or restricted intake. more...

microarray profiling of potential calorie restriction mimetics

(Submitter supplied) Mice and diets. One-month-old male mice of the long-lived B6C3F1 strain were purchased from Harlan (Indianapolis, IN) and maintained as described after weaning (15). Mice were housed in groups of 4 per cage and fed a non-purified diet, PMI Nutrition International Product #5001 (Purina Mills, Richmond, IN). At 5 months of age, the mice were individually housed, and randomly assigned to one of two groups, control (CON) or long-term CR (LTCR). more...

Short-term growth hormone treatment on the liver and muscle transcriptome in rainbow trout (Oncorhynchus mykiss)

(Submitter supplied) Although studies have established that exogenous growth hormone (GH) treatment stimulates growth in fish, its effects on target tissue gene expression are not well characterized. We assessed the effects Posilac® (Monsanto Co., St. Louis, MO), a recombinant bovine somatotropin, on tissue transcript levels. Transcript abundance was measure in liver and muscle using the GRASP 16 K cDNA microarray. A selection of the genes identified as altered with the microarray, and also transcripts for insulin-like growth factors, growth hormone receptors (GHR) and myostatins were measured by realtime PCR in the liver, muscle, brain, kidney, intestine, stomach, gill and heart. more...

Calorie Restriction Feminizes Liver Gene Expression and Alters Key Regulators of Conserved Aging Regulatory Pathways

(Submitter supplied) Background: Calorie restriction (CR) is the only intervention known to extend lifespan in a wide range of organisms, including mammals. However, the mechanisms by which it regulates mammalian aging remain largely unknown and the involvement of the TOR and Sirtuin pathways (which regulate aging in lower organisms) remain controversial. Femaleness is a second phenotype generally associated with longevity but the relationship between sex-biased and CR-induced gene expression remains undetermined. more...

Gene expression profile from short-term caloric restriction in mouse adipose tissue

(Submitter supplied) To provide a robust understanding of a transcriptomic change by short-term CR at body fat of mice, we applied three serial strengths of CR to mice including 15%, 30%, and 45% reduction of carbon source. Using Affymetrix mouse 1.0 ST array platform, we obtained and analyzed the transcriptome data for significantly changed genes in expression. Here, we identified 446 genes and categorized the genes based on their biological roles. more...

Circadian alignment of early onset caloric restriction promotes longevity in male C57BL/6J mice

(Submitter supplied) Caloric restriction (CR) prolongs lifespan, yet the mechanisms by which it does so remain poorly understood. Under CR, mice self-impose chronic cycles of 2-hour-feeding and 22-hour-fasting, raising the question whether calories, fasting, or time of day are causal. We show that 30%-CR is sufficient to extend lifespan 10%; however, a daily fasting interval and circadian-alignment of feeding act together to extend lifespan 35% in male C57BL/6J mice. more...

Gene expression in liver tissue from Ghrh-KO and normal (wild-type) mice

(Submitter supplied) The hypothalamus has recently emerged as a key regulator of metabolism and aging in mammals. We have examined the impact of targeted disruption of hypothalamic hypophysiotropic peptide: Growth Hormone-releasing Hormone (GHRH) in mice on longevity, and the putative mechanisms of delayed aging. GHRH knockout (KO) mice are remarkably long-lived and in comparison to genetically normal (wild type) animals exhibiting major shifts in the expression of genes related to xenobiotic detoxification, stress resistance, and insulin signaling. more...

Ovarian transcriptome associated with reproductive senescence in the long-living Ames dwarf mice

(Submitter supplied) The aim of the current work was to evaluate the ovarian transcriptome in Ames dwarf (df/df) mice. df/df mice have a delayed ovarian aging compared to normal (N) mice. Although a high number of genes were differentially expressed during aging of N mice, only a small fraction of these changed with aging in df/df mice. These alterations involved more than 500 categorized biological processes. The majority of these biological processes, including inflammatory/immune responses, were up-regulated with aging in N mice, while old df/df mice were characterized by down-regulation of these same processes in comparison to age matched N mice. more...
