Project description:In this study we characterize the gill transcriptome changes in Gulf killifish (Fundulus grandis) that coincide with controlled laboratory-based exposure to various concentrations of experimentally-weathered south Louisiana crude oil. Gill transcription was contrasted between doses and across timepoints following dosing.

Project description:In this study we characterize the gill transcriptome changes that coincide with the arrival of contaminating oil in field-collected Gulf killifish Fundulus grandis. Gill transcription was contrasted before and after the arrival of oil, and between oil impacted and reference sites. Animals were sampled from field sites at four times. The oil impacted site is Grand Terre Island Louisiana (GT) and the two reference sites are Bay St. Louis Mississippi (BSL) and Bayou La Batre Alabama (BLB). The first timepoint (05/01/2010 to 05/09/2010) was before the arrival of contaminating oil, the second and third timepoints (06/28/2010 to 06/29/2010, and 08/30/2010 to 09/01/2010) were after the arrival of contaminating oil, and the fourth timepoint 08/28/2011) was over a year after the arrival of contaminating oil.

Project description:The goals of these studies are to explore the mechanisms that enable extreme physiological plasticity and that may account for evolutionary divergence of adaptive osmotic physiologies among taxa that occupy different osmotic niches. In a common-garden environment, we track physiological and genome expression responses to hypo-osmotic (freshwater) challenge during a time-course of acclimation, and contrast these responses within and between species. We seek to identify mechanisms that facilitate osmotic acclimation that are evolutionarily conserved between basal and derived physiologies, and identify mechanisms that are uniquely derived to enable the extreme osmotic plasticity exhibited by F. heteroclitus. Importantly, previous studies using a comparable experimental design have identified physiological changes and genome expression responses that are adaptive for populations of F. heteroclitus that live in fresh water. As such, this enables us to test whether mechanisms of adaptive micro-evolutionary divergence across osmotic gradients within F. heteroclitus are shared with the mechanisms that account for patterns of macro-evolutionary divergence between F. heteroclitus and F. majalis that we identify in this study. That is, are the targets of micro-evolutionary fine-tuning the same or different as the targets of macro-evolutionary divergence across osmotic boundaries? Population comparisons include between populations from Chesapeake Bay (CB), coastal Virginia (VA), and coastal Georgia (GA).

Project description:The goals of these studies are to explore the mechanisms that may account for evolutionary divergence of adaptive osmotic physiologies among taxa that occupy different osmotic niches. In a common-garden environment, we track genome expression responses to hyper-osmotic (brackish water) challenge during a time-course of acclimation, and contrast these responses between species. We seek to identify mechanisms that facilitate osmotic acclimation that are evolutionarily conserved between basal and derived physiologies, and also to identify mechanisms that are uniquely derived in alternate osmotic environments.

Project description:Some studies have shown that acute intake of high-phenol virgin olive oil reduces pro-inflammatory, pro-oxidant and pro-thrombotic states, but nowadays still remains unclear if those effects attributed to its phenolic fraction could be exerted at transcriptional level in vivo. Two virgin olive oil-based breakfasts with high (398 ppm) and low (70 ppm) content of phenolic compounds were administered to twenty patients (9 men and 11 women) with metabolic syndrome following a double-blinded random crossover design. Prior to the first breakfast intervention, participants followed a 6-week washout period in which they were instructed to not take vitamins, soy supplements, or any drug. To eliminate the potential effect that might exist in their usual dietary habits, all subjects followed a low-fat, carbohydrate rich (CHO) diet during this period and untill the end of the study. In the 24 h before each breakfast intervention, participants were instructed to avoid consuming phenol-rich foods such as fruit or juices, wine, grape juice, chocolate, coffee, tea, olive oil, or soya, and to refrain from intense physical exercise during that period. After a 12 h fasting and following a randomized sequential crossover design with one-week washout period, participants reported to the hospital and received two fat meals consisting of 60 g of white bread, 40 mL of VOO (CANOLIVA®, Antonio Cano e Hijos™, Córdoba, Spain) with high (398 ppm) or low (70 ppm) content in phenolic compounds, and 60,000 IU of vitamin A per m2 of body surface. Olive oil with low content in phenolic compounds was obtained as a result of extraction by physical procedures of most of the phenolic compounds in the high-phenol olive oil, so that both oils kept a similar composition of the remaining macro- and micronutrients. Throughout the 4-h duration of the study, the subjects performed no physical activity, nor did they consume anything but water. Gene expression was performed on peripheral blood mononuclear cells (PBMCs) at postprandial period (4 hours after breakfast) by microarray analysis and verified by qRT-PCR. Two sets of dye-swaped experiments were performed making a total of four technical replicates per subject. Each of the hybridizations compared total RNA from PBMCs obtained 4h after the intake of virgin olive oil with high phenolic content vs. total RNA from PBMCs obtained 4h after low-phenol virgin olive oil consumption.
