  1. 1. Chromatin remodelling in Pol I and III transcription

    Författare :Erica Cavellán; Ann-Kristin Östlund Farrants; Gernot Längst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi;

    Sammanfattning : Compaction of chromosomes in the eukaryotic cell is due to interactions between DNA and proteins and interactions between proteins. These two types of interaction form a dynamic structure, known as "chromatin". The condensation of chromatin must be carefully regulated, since the structure is an obstacle for factors that need access to the DNA. LÄS MER

  3. 2. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones

    Sammanfattning : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.
