21. Autophagic programmed cell death in the suspensor and endosperm of Vicia faba : An ultrastructural study
Sammanfattning : Programmed cell death (PCD) is a widely spread phenomenon among multi-cellular organisms. Without the deletion of cells no longer needed, the organism will not be able to develop in a predicted way. LÄS MER
22. Studies of histone modification systems in Schizosaccharomyces pombe
Sammanfattning : The genetic information in every cell is carried in the DNA. In eukaryotes the DNA is wrapped twice around proteins called histones forming a repeating unit called the nucleosome, in fibers known as chromatin. Nucleosomes are folded into higher order structures forming the chromosomes. LÄS MER
23. Chromatin regulators and transcriptional control of Drosophila development
Sammanfattning : The development of a multicellular organism is programmed by complex patterns of gene expression. In eukaryotic cells, genes are packaged by histone proteins into chromatin. Chromatin regulators often function as transcription co-factors. LÄS MER
24. Modulating chromatin by transcription and nucleosome turnover : a genome-wide study in fission yeast
Sammanfattning : Eukaryotic DNA is wrapped around histone proteins to form a nucleosome, the basic structural unit of chromatin. Multiple levels of chromatin organization are required to compact DNA into chromosomes, to ensure an accurate cell division. LÄS MER
25. Exploring the dynamic epigenome in pluripotent stem cells using quantitative methods
Sammanfattning : A totipotent stem cell has the potential to give rise to the trillions of cells in the human body, all carrying the very same genetic information. Through differentiation events, gene expression changes guided by epigenetic mechanisms resulting in specialized phenotypes. LÄS MER
