  1. 1. Heritable epigenetic responses to environmental challenges : Effects on behaviour, gene expression and DNA-methylation in the chicken

    Författare :Daniel Nätt; Per Jensen; Adroaldo Zanella; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Phenotypic variation within populations is a crucial factor in evolution and is mainly thought to be driven by heritable changes in the base sequence of DNA. Among our domesticated species we find some of the most variable species on earth today. LÄS MER

  3. 2. Stress and the Offspring : Adaptive Transgenerational Effects of Unpredictability on Behaviour and Gene Expression in Chickens (Gallus gallus)

    Författare :Daniel Nätt; Per Jensen; Berry Spruijt; Linköpings universitet; []
    Nyckelord :Chicken; Red junglefowl; Domestication; Epigenetics; Transgenerational; Inheritance; Gene expression; Microarray; qRT-PCR; Immunogenetics; Immunoglobulin; Estradiol; Steriod hormones; Prenatal stress; Epigenetic inheritance; Adaptation; Stress; Behaviour; Ethology of domestic animals; Husdjurens etologi;

    Sammanfattning : Environmental stress has shown to affect both the exposed individuals and the development of their offspring. Generally, it is thought that the stressed organism responds to stress by trying to adapt to it. LÄS MER

  4. 3. Epigenetic dysregulation in relation to psychiatric traits in adolescence and adulthood

    Författare :Adrian Desai Boström; Helgi B. Schiöth; Daniel Nätt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; methylome-wide; DNA methylation; hypersexual disorder; microRNA; oxytocin signaling; psychiatry; hsa-miR-4456; microRNA-4456; MIR4456; epigenetic dysregulation; microRNA expression; gene target prediction; epigenetics; suicide; suicide attempt; HPA axis; CRH gene; Epigenetics; Methylation; Adolescent depression; MIR4646; methylome-wide association study; Omega-3; mQTL analysis; GAD1; HDAC3; DAWBA;

    Sammanfattning : Epigenetics has evolved into a key research focus in the field of psychiatry. DNA methylation is the most researched epigenetic mechanism. In paper I-III, 130 and 93 adolescents were randomly recruited at two separate intervals. LÄS MER

  5. 4. Small non-coding RNA in early fly development : plasticity, interactions and improved bioinformatic tools

    Författare :Lovisa Örkenby; Anita Öst; Rashmi Ramesh; Daniel Nätt; Nicola Iovino; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila; Maternal-to-zygotic transition; sncRNA; miRNA; piRNA; Embryogenesis; Zygotic gene activation;

    Sammanfattning : At fertilization, the male and female pronuclei undergo a transformation from germline to pluripotency as they fuse, marking the beginning of Drosophila embryogenesis. As the parental contributions decrease, the zygote takes control of its genome in a process called the maternal-to-zygotic transition (MZT). LÄS MER
