Expression data from aged wild-type, met15Δ and rtg3Δ met15Δ yeast

ABSTRACT: To explore putative connections between genetic methionine restriction and the retrograde response, we asked whether the altered transcriptional program of methionine-restricted cells required RTG3 (which is indispensible for retrograde signaling in yeast).

Expression data from aged wild-type, met15Δ and rtg3Δ met15Δ yeast

Project description:To explore putative connections between genetic methionine restriction and the retrograde response, we asked whether the altered transcriptional program of methionine-restricted cells required RTG3 (which is indispensible for retrograde signaling in yeast). Towards this end, we used Affymetrix GeneChip Yeast Genome 2.0 arrays to perform expression profiling of aged (Day 3) wild-type, met15Δ and rtg3Δ met15Δ yeast.

scRNA-seq of aged Drosophila midgut under methionine restriction

Project description:Methionine restriction is known to extend lifespan in various model organisms including Drosophila melanogaster. In this analysis, we performed scRNAseq of Drosophila female midgut samples to understand the cell type specific response to methionine restriction.

Effects of 20 months Dietary Methionine Restriction on Hepatic Gene Expression in Fischer 344 Rats

Project description:Dietary methionine restriction (MR) has been shown to increase lifespan and decrease adiposity in rodents. This study was designed to examine the transcriptional effects of MR in metabolically relevant tissues. This experiment contains data from the liver. We analyzed MR-induced changes in gene expression using pooled RNA from liver of rats fed either a control purified amino acid diet (DL-methionine content of 0.86%) (CON) or a methionine-restricted diet (DL-methionine content of 0.172%)(MR). Rats were fed Purina rodent diet 5001 until 32 days of age and were then randomly assigned to be fed CON diet or MR diet for 20 months.

Effects of 20 months Dietary Methionine Restriction on Gene Expression in inguinal white adipose tissue of Fischer 344 Rats

Project description:Dietary methionine restriction (MR) has been shown to increase lifespan and decrease adiposity in rodents. This study was designed to examine the transcriptional effects of MR in metabolically relevant tissues. This experiment contains data from the inguinal white adipose tissue (IWAT). We analyzed MR-induced changes in gene expression using pooled RNA from IWAT of rats fed either a control purified amino acid diet (DL-methionine content of 0.86%) (CON) or a methionine-restricted diet (DL-methionine content of 0.172%)(MR). Rats were fed Purina rodent diet 5001 until 32 days of age and were then randomly assigned to be fed CON diet or MR diet for 20 months.

Dietary methionine restriction impairs anti-tumor immunity through gut microbiota

Project description:Dietary methionine restriction represses growth and improves therapeutic responses in several pre-clinical settings. However, how this dietary intervention impacts cancer progression in the context of the immune system is unknown. Here we analyzed the CD45+ immune cells from the small intestine of control (CTRL) diet or methionine-restricted (MR) diet fed tumor-free C57BL/6J donor mice and tumor-bearing Apc <min+/-> recipient mice transplanated with feces from these diet-fed tumor-free C57BL/6J mice by scRNA-seq. Our analysis indicate that fecal microbes from methionine-restricted tumor-free C57BL/6J mice are sufficient to represss T cell activation in the small intestine of Apc <min+/-> mice.

Hepatic gene expression analysis from rats with chronic sleep restriction

Project description:We report the change in gene expression in rat liver post chronic sleep restriction. Rats were sleep restricted by for 5 days by forced activity protocol. We found changes in genes related to NAD metabolism (Nampt), TCA cycle (Acly) and methionine metabolism (Msrb2 and Mtr)

SIRT1 regulates methionine metabolism and pluripotency of mouse embrynoic stem cells (mESCs)

Project description:The goal of this project is to understand the role of SIRT1, the most conserved mammalian NAD+-dependent protein deacetylase, in methionine metabolism and pluripotency of mESCs. Our recent studies indicate that SIRT1 deficient mESCs are hypersensitive to methionine restriction-induced differentiation and apoptosis, primarily due to a reduced conversion of methionine to S-adenosylmethionine. This reduction leads to marked decrease in methylation levels of histones in SIRT1 deficient mESCs. To understand the impact of histone methylation alterations on stem cell functions in SIRT1 KO mESCs, we examined the transcriptomes of SIRT1 WT and KO mESCs cultured in either complete M10 medium (com) or methionine restricted medium containing 6 uM methionine (6met) for 6, 24, and 72 hours by microarray analysis.

Expression data from dietary restricted budding yeast

Project description:Dietary restriction (also known as caloric/calorie restriction; CR) extends the lifespan of species from all three eukaryotic kingdoms. The restriction of the diet interferes directly with the aging process by triggering a tightly controlled genetic program where specific sets of genes are either upregulated downreguled. We used microarray-technology to detail the global program of gene expression underlying the anti-aging effect of dietary restriction and identified distinct classes of up- and down-regulated genes. In order to apply dietary restriction in budding yeast we cultured cells on a reduced glucose medium (0.5% vs. 2.0%), which is known as moderate DR regimen. We then compared mRNA expression of yeast cells cultured under dietary restricted (0.5% glucose) and ad libitum (2.0% glucose) conditions.
