Transcriptomics of C. chinensis and E. ulmoides treated aged C. elegans

Project description:The nematode Caenorhabditis elegans was treated with extracts of the Traditional Chinese Medicine plants Cuscuta chinensis and Eucommia ulmoides from the L4 stage. In aged worms (on the 7th and 12th day of adulthood) different health parameters were determined. Besides the prolongation of lifespan, we found that C. chinensis improved the swimming behavior, pharyngeal pumping rate, stress resistance, mechanosensation and memory of aged C. elegans. Furthermore, the extract treatment reduced the autofluorescence, which is a known biomarker of ageing. Thus, we concluded that C. chinensis is an overall healthspan enhancer. In contrast, the E. ulmoides extract specifically enhanced the lifespan and stress resistance of aged C. elegans, but did not improve any other health aspect. To reveal the mechanism behind the healthspan enhancing effects of C. chinensis, the transcriptome of treated and untreated C. elegans on the 12th day of adulthood was analysed. For comparison purposes, E. ulmoides treated nematodes were included in the analysis.

Characterization of hyperglycemia due to sub-chronic administration of red ginseng extract via comparative global proteomic analysis

Project description:Ginseng (Panax ginseng Meyer) is commonly used as an herbal remedy worldwide. Few studies have explored the possible physiological changes in the liver although patients often self-medicate with ginseng preparations, which may lead to exceeding the recommended dose for long-term administration. Here, we analyzed changes in the hepatic proteins of mouse livers using quantitative proteomics after sub-chronic administration of Korean red ginseng (KRG) extract (control group and 0.5, 1.0, and 2.0 g/kg KRG) using tandem mass tag (TMT) 6‐plex technology. The 1.0 and 2.0 g/kg KRG groups exhibited signs of liver injury, including increased levels of aspartate transaminase (AST) and alanine aminotransferase (ALT) in the serum. Furthermore, serum glucose levels were significantly higher following KRG administration compared with the control group. Based on the upregulated proteins found in the proteomic analysis, we found that increased cystathionin beta-synthase (CBS) and cystathionine gamma-lyase (CSE) levels promoted greater hydrogen sulfide (HRR2RRS) synthesis in the liver. This investigation provides novel evidence that14T sub-chronic administration of 4T14TKRG can elevate HRR2RRS production by increasing protein expression of CBS and CSE in the liver.

Hepatic gene expression profile in persimmon peel extract administrated GK rat

Project description:Persimmon (Diospyros kaki L. f.) is a most popular fruit in Asian countries but its peels are totally wasted despite of containing a plenty of antioxidants such as carotenoids and polyphenols. We prepared a fat-soluble extract from a persimmon peel (PP) fraction and fed type 2 diabetic Goto-Kakizaki (GK) rats with a PP extract-containing AIN-93G diet (PP diet) for 12 weeks. Compared with the control AIN-93G diet, the feeding of the PP diet reduced the plasma glutamic-pyruvate transaminase activity significantly, with accumulation of M-NM-2-cryptoxanthin in the liver. A DNA microarray analysis revealed that the PP diet altered the hepatic gene expression profiles. In particular, insulin signaling pathway-related genes were significantly enriched in differentially expressed gene sets. Moreover, Western blotting analysis actually showed the promotion of IRM-NM-2 tyrosine phosphorylation. All these data suggest that the PP extract administration to the GK rats improves their insulin resistance. Male GK rats (90M-bM-^@M-^S107 g), aged 5 weeks, were purchased from Japan SLC Co. (Hamamatsu, Japan). The rats were maintained in a room at 22 M-BM-1 1M-BM-0C under a 12-h light-dark cycle (lights on at 0800) and administered a commercial diet (AIN-93G, Research Diets, Inc., New Brunswick, NJ, USA) for a week. The rats were allowed free access to diet and water. After one week, they were divided into two groups with similar average body weights. The control group rats (n = 4) were fed on the commercial diet, and the PP group rats (n = 4) on the same diet containing the PP extract. After the 12-week-feeding the liver was excised and analyzed the effect of PP extract administration on hepatic gene expression.

Mechanical regulation of the glucocorticoid-sensitive transcriptome in young and aged skeletal muscle

Project description:Elevated glucocorticoids alter the skeletal muscle transcriptome to induce a myopathy characterized by muscle atrophy, muscle weakness, and decreased metabolic function. These effects are more likely to occur and be more severe in aged muscle. Resistance exercise can blunt development of glucocorticoid myopathy in young muscle, but the potential to blunt the signals initiating myopathy in aged muscle is unknown. To answer this, young (4-month-old) and aged (24-25-month-old) male C57BL/6 mice were randomized to receive either an intraperitoneal (IP) injection of dexamethasone (DEX; 2 mg/kg) or saline as a control. Two hours post-injections, tibialis anterior (TA) muscles of mice were subjected to unilateral high force contractions. Muscles were harvested four hours later. The glucocorticoid- and contraction-sensitive genes were determined by RNA sequencing. The number of glucocorticoid sensitive genes was similar between young and aged muscle. Contractions altered more glucocorticoid-sensitive genes in aged muscle, with this outcome primarily occurring when hormone levels were elevated. Glucocorticoid-sensitive gene programs altered by contractions were primarily related to metabolism in young mice and muscle size regulation and inflammation in aged mice. In silico analysis implied Peroxisome proliferator-activated receptor gamma-1 (PPARG) contributed to the contraction-induced changes in glucocorticoid-sensitive genes in aged muscle. Increasing PPARG expression in the TA of aged mice using Adeno-associated virus serotype 9 partially counteracted the glucocorticoid-induced reduction in Runt-related transcription factor 1 (Runx1) mRNA content, recapitulating the effects observed by contractions. Overall, these data contribute to our understanding of the mechanical regulation of the glucocorticoid transcriptome in aged skeletal muscle.

Impact of oral compost-extract administration on gene expression in the rat gastrointestinal tract

Project description:Oral administration of an extract of compost fermented with thermophiles to pigs reduces the incidence of stillbirth and promotes piglet growth. However, the mechanism by which compost extract modulates the physiological conditions of the animals remains largely unknown. Here, we investigate the effects of compost extract on the gene expression in the intestine of the rat as a mammalian model. Gene expression analyses of the intestine indicated that several immune-related genes were upregulated following compost exposure. Thus, thermophile-fermented compost can contain microbes and/or substances that activate the gut mucosal immune response in the rat. In Male Wistar rats aged 3 weeks, tap water was supplemented with 1.0% (v/v) compost extract for the experimental rats, whereas water only was given to the control rats. The rats received water ad libitum for 12 weeks. Fresh gut samples were collected from individual rats at the end of the feeding test and stored at -80Â°C. The intestine were separated from the gut and used as samples for the isolation of total RNA. otal RNA was then subjected to microarray experiments using the Whole Rat Genome (4x44k) Oligo Microarray (Agilent Technologies, Inc.)

Effects of aged garlic extract (AGE) and FruArg on lipopolysaccharide-induced genetic response in microglial cells using gene expression profiling

Project description:We hypothesized that aged garlic extract, and a pure compound from it, FruArg, can repress the genetic response induced by lipopolysaccharide (LPS). We applied gene expression profiling to understand the potential mechanisms of the protective effects of AGE and FruArg against LPS stress in BV-2 cells. Gene expression profiling showed that AGE repressed the transcriptome alteration induced by LPS. FruArg, as an active compound in AGE, accounted for AGE's protective effects. These results suggest that AGE and FruArg are capable of alleviating oxidative and neuroinflammatory responses stimulated by LPS in BV-2 cells.
