(Submitter supplied) PFJ (4 ml for a final concentration of 19,000 mg gallic acid equivalent (GAE) per kg diet or 0.86 mg GAE per kcal diet) was supplemented to larvae of fruit flies (Drosophila melanogaster) given a semi-purified diet to observe for possible effects on energy metabolism and lifespan. Fat bodies extracted from these larvae were used five days since the egg stage for gene expression studies. Results from the microarray data analysis carried out show that fruit fly larva fat bodies given PFJ had up-regulated heat shock protein genes, while cell cycle and growth genes were down-regulated.

(Submitter supplied) Microarray analysis on livers of young (three weeks old) Nile rats (Arvicanthis niloticus) fed with either a high carbohydrate diet only (percentage energy from carbohydrate:fat:protein = 70:10:20, 16.7 kJ/g) or a high carbohydrate diet supplemented with palm fruit juice (PFJ) (415 ml of 13000 ppm gallic acid equivalent (GAE) for a final concentration of 5.4 g GAE per kg diet or 2.7 g per 2000 kcal) PFJ (415 ml of 13000 ppm gallic acid equivalent (GAE) for a final concentration of 5.4 g GAE per kg diet or 2.7 g per 2000 kcal) was supplemented to young Nile rats (Arvicanthis niloticus) given a high carbohydrate diet (percentage energy from carbohydrate:fat:protein = 70:10:20, 16.7 kJ/g) to observe for possible anti-diabetic effects. more...

(Submitter supplied) Although radiation effects have been extensively studied, the biological effects of low-dose radiation (LDR) are controversial. This study investigates LDR-induced alterations in locomotive behavior and gene expression profiles of Drosophila melanogaster. We measured locomotive behavior using larval pupation height and rapid iterative negative geotaxis (RING) assay after exposure to 0.1 Gy gamma-radiation (dose rate of 16.7 mGy/h). more...

(Submitter supplied) OPP (1500 ppm gallic acid equivalent (GAE)) was supplemented to BALB/c mice given a normal diet to observe for possible neuroprotective effects. Brains were harvested six weeks after the feeding regimen for gene expression studies. Results from the separate microarray data analysis carried out on the different organs show that OPP have neuroprotective properties in vivo.

(Submitter supplied) We investigated the hormetic effects of prenatal hyperbaric normoxia exposure on Drosophila healthspan related to molecular defense mechanisms. HN exposure had no disruptive effect on developmental rate or adult body weight. However, lifespan was clearly enhanced, as was resistance to oxidative and heat stress. In addition, levels of reactive oxygen species were significantly decreased and motor performance was increased. more...

(Submitter supplied) We investigated the consequences of chronic circadian misalignment (CCM) in the powerful model system of the fruit fly, Drosophila melanogaster. We subjected flies to daily 4-hr phase delays in the light-dark schedule and used the Drosophila Activity Monitoring (DAM) system to continuously track locomotor activity and sleep while simultaneously monitoring fly lifespan. Consistent with previous results, we find that exposing flies to CCM leads to a ~15% reduction in median lifespan in both male and female flies. more...

(Submitter supplied) Gut and rest of body tissue from fifth instar larvae which fed for three days a diet containing different doses of gossypol. Transcriptional profiling comparing gut and rest of body samples for three gossypol concentrations (0%, 0.016%-hormetic dose & 0.16%-detrimental dose). Hormesis is a biphasic biological response characterized by the stimulatory effect at relatively low amounts of chemical compounds otherwise known to be detrimental at higher concentrations. more...

(Submitter supplied) Many studies have addressed the effects of adult diet on gene expression in Drosophila melanogaster, however, little is known about how developmental diet influences adult gene expression, and how this interacts with adult dietary conditions. We found that developmental and adult diet exert largely independent effects on gene expression, with the effect of adult diet being considerably larger.We did find effects of developmental diet on the transcriptome that persist into middle and old-age. more...

(Submitter supplied) OPP (1500 ppm gallic acid equivalent (GAE)) was supplemented to BALB/c mice given an atherogenic diet for six weeks to observe for possible anti-atherogenic effects. The control group received distilled water instead of OPP. Livers, spleens and hearts were harvested six weeks after the feeding regimen for gene expression studies. Results from the separate microarray data analysis carried out on the different organs show that OPP attenuated the effects of the atherogenic diet in the organs.

(Submitter supplied) BALB/c mice were given an atherogenic diet and compared to those given a normal diet to observe for gene expression changes caused by the atherogenic diet. Both groups of mice received distilled water as drinks ad libitum. Livers, spleens and hearts were harvested six weeks after the feeding regimen for gene expression studies. Results from the separate microarray data analysis carried out on the different organs show that the atherogenic diet caused oxidative stress and inflammation in the organs.

(Submitter supplied) The mechanisms underlying natural variation in lifespan and ageing rate remain largely unknown. We performed microarray experiment to characterise genome-wide expression patterns of a long-lived, natural variant of Drosophila melanogaster resulting from selection for starvation resistance (SR) and compare it with normal-lived control flies (C).

(Submitter supplied) We used cell-type-specific ribosome profiling (Ribo-tag) to study the impacts of aging and oxidative stress on the expression of actively translated mRNA in adult Drosophila oenocytes. Polysome associated mRNAs from oenocyte were extracted from young flies and aged flies, treated with water or paraquat. Restults provide insight into aging mechanism and tissue specific response to stress in oenocyte.

(Submitter supplied) Primary bile acids are produced in the liver whereas secondary bile acids such as lithocholic acid (LCA) are generated by gut bacteria from primary bile acids that escape the ileal absorption. Besides their well-known function as detergents in lipid digestion, bile acids are important signaling molecules mediating effects on the host’s metabolism. As energy metabolism is closely linked to aging and longevity we supplemented fruit flies (Drosophila melanogaster) with 50 µmol/l LCA either for 30 days or throughout their lifetime. more...

(Submitter supplied) Postmitotic tissues are incapable of replacing damaged cells through proliferation, but need to rely on buffering mechanisms to prevent tissue disintegration. By constitutively activating the Ras/MAPK-pathway via RasV12-overexpression in the postmitotic salivary glands of Drosophila larvae, we overrode the glands adaptability to growth signals, induced hypertrophy and stress accumulation. This allowed us to decipher a novel, spatio-temporally regulated interaction between the JNK-stress response and a genuine tissue-autonomous immune response. more...

(Submitter supplied) Although airway epithelia are primarily devoted to gas exchange, they have to fulfil a number of different tasks including organ maintenance and the epithelial immune response to fight airborne pathogens. These different tasks are at least partially accomplished by specialized cell types in the epithelium. In addition, a proximal to distal gradient mirroring the transition from airflow conduction to real gas exchange, is also operative. more...

(Submitter supplied) We sequenced mRNA extracted from brains of (1) D. melanogaster larvae exposed to food containing 5% ethanol (v/v) for 6 conscutive days, and (2) an age-matched untreated control larvae, that grew in regular food. Differential gene expression between the two groups was calculated and reported. Each group consisted of 3 biological replicates of 30 brains each.
