  2. 11. lac of Time : Transcription Factor Kinetics in Living Cells

    Author : Petter Hammar; Johan Elf; Antoine van Oijen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene regulation; transcription factor; lac operon; facilitated diffusion; single molecule imaging; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. READ MORE

  4. 12. Preproenkephalin Gene and mRNA : Studies of Structure, Function, Cocaine Responses in an Animal Model, and Genetic Association with Human Opiate Addiction

    Author : Karl Steven LaForge; Fred Nyberg; Peter S. Eriksson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Neuropeptides; Endogenous opioid system; Drug addiction; Heroin; Cocaine; Gene expression; Genetic association; Biologisk beroendeforskning; Biological research on drug dependence; Biologisk beroendeforskning;

    Abstract : The endogenous opioid enkephalin neuropeptides are mediators of pain perception and have been implicated in human addictions. The preproenkephalin gene and its mRNA have also provided many examples of tissue- and species-specific variations in mRNA structure produced through a variety of transcriptional and post-transcriptional mechanisms.

  5. 13. Regulators of chromatin and transcription in Drosophila

    Author : Filip Crona; Mattias Mannervik; Fernando Azorin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transcription; chromatin; co-regulators; CBP; lysine demethylase; KDM4A; Brakeless; Drosophila; utvecklingsbiologi; Developmental Biology;

    Abstract : Development of multicellular organisms is achieved by organized temporal and spatial patterns of gene expression leading to cell differentiation. Chromatin regulators control how the DNA is utilized by altering access of proteins to DNA and thereby function as co-factors in transcription. READ MORE

  6. 14. Transcription regulation across levels of chromatin organization

    Author : Roshan Vaid; Mattias Mannervik; Goncalo Castelo-Branco; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transcription; chromatin; epigenetics; Drosophila; embryo development; molekylär biovetenskap; Molecular Bioscience;

    Abstract : With advancements in high-throughput sequencing and high-resolution microscopy techniques, the significance of genome organization in transcription regulation is rapidly unveiling. Nonetheless, we are yet far from completely understanding this key relationship. READ MORE

  7. 15. Maf transcription factors in beta cell function

    Author : Elvira Ganic; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Beta cell; MafA; type 2 diabetes; insulin secretion; transcription; monoamine oxidase; MaoA; MaoB; nicotinic receptor subunits; nAChRs;

    Abstract : Diabetes mellitus is metabolic disorder caused by a defect or lack of beta cell-produced insulin that controls blood glucose homeostasis. In addition to glucose, insulin secretion is regulated by the autonomic nervous system (ANS); the neurotransmitter acetylcholine as well as monoamines, such as dopamine, serotonin, melatonin and norepinephrine.
