  2. 6. Genome-wide patterns of histone modifications in fission yeast

    Author : Indranil Sinha; Karl Ekwall; Karin Dahlman-Wright; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : DNA is wrapped almost two times around a group of proteins called histones to form a chromosomal structure known as the nucleosome. Both DNA and histones can be modified with different chemical tags by several enzymes to activate or suppress a particular gene or group of genes. Histones can be covalently modified at several places. READ MORE

  4. 7. Dissecting the epigenetic landscapes of hematopoiesis and fission yeast

    Author : Michelle Rönnerblad; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The genome of eukaryotic cells is stored in the nucleus as chromatin, a DNA-protein complex that serves to compact and protect the DNA molecules. The basic unit of chromatin is the nucleosome composed of DNA wrapped around a histone protein core. READ MORE

  5. 8. Fission yeast mediator complex and its role in transcriptional regulation

    Author : Olga Khorosjutina; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Mediator is an evolutionary conserved co-activator complex that regulates transcription of protein encoding genes in eukaryotes. This multiprotein complex was first identified in budding yeast and shown to be indispensable for RNA polymerase II (pol II) dependent transcription. READ MORE

  7. 10. Genetic analysis of cell cycle and chromatin regulation in quiescent fission yeast cells

    Author : Yasaman Zahedi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : During proliferation, cells produce their genetic materials to increase the number of cells, while in the absence of nutrients or by the induction of stimulus, the proliferative phase is stopped and entry into quiescence is triggered to increase their chance of survival. Quiescence is a reversible resting phase where cells enter, in case of nutrient deprivation or damage and induced by stimuli. READ MORE
