Transcription profiling by array of Danio rerio fast skeletal muscle from fish fed a single satiating meal

Project description:The F5 generation of a wild-caught population of zebrafish (Danio rerio) from Mymensingh, Bangladesh, were used in this study. Replicate experiments were carried out with adult male fish aged 9 months. Each group was maintained in a 50L tank at 27M-11.5M-:C and 12:12h dark:light photoperiod and fed bloodworms (Ocean NutritionM-^Y, Belgium) to satiety for one week. The experimental protocol involved fasting fish for 7 days and subsequent refeeding a single meal of bloodworms delivered over a 3h period, after which any uneaten food was removed from the tank. Seven fish were sampled at -156, -24, 0 (prior to the meal), 0.75, 3, 6, 7.5, 9, 11, 24, 36h and killed humanely by an overdose of ethyl 3-aminobenzoate methanesulfonate salt (MS-222). Six samples from the 0, 3, and 6h time-points were used in the microarray hybridization.

Transcription profiling by array of Brachypodium response to increased ambient temperature in seedlings

Project description:Microarray analysis on Brachypodium distachyon seedlings was performed to determine the response of the transcriptome to changes in ambient temperature, including identification of marker genes that were up-regulated or down-regulated by a moderate increase in growth temperature. Wild-type Brachypodium (Bd21) seedlings were grown on MSR63 media without sucrose (Alves et al. 2009 Nature Protocols vol. 4 pp 638-649) in a short-day photoperiod (14 hr light/ 10 hr dark) at 17 ºC. As the third leaf was emerging, plants were transferred to 12 ºC for 48 hrs. Plants were then maintained at 12 ºC or transferred to one of two temperature treatments: constant 22 ºC or constant 27 ºC. Samples were collected before the shift (0 hr) and at 2 hr and 24 hr after the shift and immediately frozen in liquid nitrogen. For each harvest, two to three replicates were collected that each contained 3 seedlings.

IDS transgen arraYS

Project description:Adult female Wistar rats (about 220g) obtained from a breeding colony were mated and fed either a protein sufficient (PS) or protein restricted (PR) diet (n = 6 per dietary group) during F0 pregnancy which provided an increase in energy of approximately 25% compared to the diet fed to the breeding colony (2018S). During lactation dams were fed AIN93G and litters were standardisied to 8 offspring within 24 hours of birth with a bias towards females. Offpsring were weaned onto AIN93M at postnatal day 28 and F1 and F2 females were mated on postnatal day 70 (n = 6 per F0 dietary group). F1 and F2 dams were fed the PS diet during pregnancy and AIN93G during lactation. Offspring were weaned onto AIN93M. On postnatal day 70 unmated female offspring were fasted for 12 hours then sacrificed for hepatic transcritpome analysis by microarray. Expression of 1,684 genes differed by at least 2 fold between adult female F1 offspring of F0 dams from both dietary groups. 1680 genes were altered in F2 offspring and 2,065 genes altered in F3 offspring. Expression of 113 genes was altered in all three generations. Of these, 47% showed directionally opposite differences between generations. Gene ontology analysis revealed clear differences in the pathways altered in each generation. F1 and F2 offspring of F0 dams fed a PR diet showed impaired fasting glucose homeostasis. Hepatic phosphoenolpyruvate carboxykinase (PEPCK) expression was elevated in F1 and F2 offspring from F0 PR dams, but decreased in F3, compared to PS offspring
