  1. 11. Identifying Cell Reprogramming Roadblocks by Modelling Induced Pluripotency with Boolean Networks and Dynamical Systems

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Johannes Isaksson; [2018]
    Keywords : Stem cells; pluripotency; pluripotent; reprogramming; iPS; induced pluripotency; Boolean; dynamical systems; network.; Medicine and Health Sciences;

    Abstract : The generation of induced pluripotent stem (iPS) cells from differentiated cells is a process of great scientific interest due to the medical potential of such cells. This process (called 'reprogramming' of cells) is however notoriously inefficient and still not very well understood. READ MORE

  3. 12. Utilizing data from a new, quantitative ChIP-sequencing method to investigate the dynamics of histone H3.3

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Turid Everitt; [2018]
    Keywords : Epigenomics; Histone H3.3; Chromatin dynamics; ChIP-seq;

    Abstract : DNA is a key component of almost all cells, but it is not the sole determinant of the cellular functions and features. A great number of histones, transcription factors and other proteins interact with the DNA, regulating fundamental processes such as DNA accessibility and gene expression. READ MORE

  4. 13. Modelling conversion of adult skin cells to neurons

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Viktor Drugge; [2018]
    Keywords : Human adult fibroblast; Neuron; Neural conversion; Transdifferentiation; Direct reprogramming; Direct lineage conversion; Simulation; Regulatory gene network; Gene network topology; Gene circuit; Gene dynamics; Physics and Astronomy;

    Abstract : Scientists are now able to directly convert one somatic cell type into another using a procedure known as direct lineage reprogramming or transdifferentiation. In this procedure, transcription factors which are important for initiating a rewriting of the gene expressions are introduced in the cell. READ MORE

  5. 14. Population biology and ecology in the rare and endangered Hapalopilus croceus.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Deanne Greaves; [2017]
    Keywords : mycology; population biology; fungal genetics; endangered fungi; hapalopilus; oak fungi; saffransticka; eksvamp;

    Abstract : Landscape management has altered the population dynamics of many species residing in old growth ecosystems. As a result, fragmentations in residual old oak habitats in Sweden have led to the decline of endangered and long-lived polypores including the bright orange Hapalopilus croceus. READ MORE

  6. 15. Diffusion in fractal globules

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jakob Hariz; [2016]
    Keywords : Fractal Globule; Anomalous Diffusion; Diffusion; DNA;

    Abstract : Recent experiments suggest that the human genome (all of our DNA) is organised as a so-called fractal globule. The fractal globule is a knot--free dense polymer that easily folds and unfolds any genomic locus, for example a group of nearby genes. Proteins often need to locate specific target sites on the DNA, for instance to activate a gene. READ MORE
