  1. 1. Analysis of DNA methylation changes and behavioural outcomes in adulthood induced by prenatal exposure to a mixture of endocrine disrupting chemicals

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Shane Kamil; [2022]
    Keywords : Toxicology; Developmental biology; Epigenetics; Genetics; Methylation; EDC; Toxins; Chemicals; Mixture effect; Mediation; Toxikologi; Utvecklingsbiologi; Epigenetik; Genetik; Metylering; Miljögifter;

    Abstract : Endocrine disrupting chemicals, or EDCs, are some of the most prevalent toxic chemicals found in the environment because of human activity and they have a variety of adverse effects on both humans and wildlife. A proposed mechanism through which EDCs can negatively affect an organism is via an epigenetic mechanism known as DNA methylation, which can affect the development of the organism with negative outcomes later in life.

  3. 2. Epigenetiskt arv

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Moa Lindell; [2019]
    Keywords : epigenetik; epigenetisk nedärvning; epigenetiska mekanismer;

    Abstract : Epigenetik är den del av genetiken som behandlar förändringar i genuttryck som är oberoende av förändringar i DNA-sekvensen. Det som styr vilka gener som uttrycks och får effekt på fenotyp har studerats av forskare sedan 70-80-talet. READ MORE

  4. 3. Grb10 and developmental programming: evaluation of a maternal diet restriction model during gestation

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Daniel Bergman; [2015]
    Keywords : Grb10; epigenetics; imprinting; gene imprinting; developmental programming; DNA; methylation; material restriction diet; gestation; knock-out mice; obesity; diabetes; coronary heart disease; huypertension; epigenetik; prägling; genomisk prägling; perinatal programmering; metylering; maternell restriktionsdiet; dräktighet; knock-outmöss; övervikt; diabetes; hjärt - och kärlsjukdom; hypertoni;

    Abstract : This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart disease and hypertension) caused by environmental factors during development. This phenomenon is known as developmental programming. READ MORE

  5. 4. Genetiska och epigenetiska samband mellan näringsförsörjning och fertilitet hos mjölkkor

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Stina Hellman; [2013]
    Keywords : Epigenetik; fertilitet; NEB; hullpoäng; leptin; NEFA; BHB; IGF-1; urea;

    Abstract : The dairy cow’s ability to resume estrus after calving and to conceive is affected by their metabolic status after calving. For high yielding cows there is a high risk that the feed intake will not be sufficient to cope with the increased energy demands after calving, and the cow will end up in a state of negative energy balance.

  6. 5. Epigenetic regulation of the Igf2/H19 gene cluster

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Matilda Nordin; [2012]
    Keywords : Igf2; H19; epigenetik; prägling; metylering; kromatin;

    Abstract : Igf2 (insulin-lik tillväxtfaktor 2) och H19 är präglade gener hos däggdjur. Präglade gener uttrycks ojämnt; den allel som ärvts från den ena föräldern uttrycks mer än den från den andra. Igf2-genen kodar för en viktig embryonal tillväxtfaktor och uttrycks till protein bara från den paternella allelen. READ MORE
