Project description:Expression profiles of porcine muscle Semimembranosus were studied to identify genes beeing significantly affected by pre-slaughter stress or no stress treatment in pigs of different breed (Italian Duroc, Italian Large White or Pietrain) and differnt Halothane genotype (RYR1 locus CC-NN, CT-Nn or TT-nn) in Pietrain pigs.

All 36 samples were hybridised together with a common reference.
Project description:The Swedish haemangioma cohort consists of 17,200 women treated with radium-226 for skin haemangioma at an early age (<1.5 years of age) between 1920 and 1965. A total of 877 breast cancer cases were reported by December 2009, estimating an excess relative and absolute risk at the age of 50 years of 0.48 Gy^(−1) and 10.4 (10^4 PYR Gy)^(−1), respectively. We screened 31 primary breast carcinomas for genetic alterations using the OncoScan CNV Plus Assay to assess genomic instability.
Project description:Plants display remarkable developmental and phenotypic plasticity in order to adapt to their environment. It has long been postulated that epigenetics plays a key role in these processes, but with one or two exceptions, solid evidence for the role of epigenetic variation in these processes is lacking. A key impediment to understanding these processes is the lack of information on the extent of epigenetic variation and how it relates to genetic and phenotypic variation in natural population, both over the lifecycle of an individual, and over evolutionary time. Here we show that genetic variants under selection in the north of Sweden appear to drive variation in DNA methylation, which in turn is highly correlated with local climate. Selective sweeps and genetic variants associated with adaptation to the local environment have previously been identified within the Swedish Arabidopsis population. Our finding that they harbour variants responsible for climate associated epigenetic variation strongly supports the role of epigenetic processes in local adaptation. These findings provide a basis for further dissecting the role of epigenetics in local adaptation at the molecular level Bisulfite sequencing of 113 F2 crosses between T550 and Brosarp-11-135.
