  2. 1. The Heterogenic Final Cell Cycle of Retinal Horizontal Cells

    Author : Shahrzad Shirazi Fard; Finn Hallböök; Ulla Pirvola; Uppsala universitet; []
    Keywords : Apoptosis; Checkpoint; DNA damage; Differentiation; Heteroploid; Endoreplication; Proliferation; Tumor; Neuroscience; Neurovetenskap;

    Abstract : The cell cycle is a highly complex process that is under the control of several pathways.  Failure to regulate and/or complete the cell cycle often leads to cell cycle arrest, which may be followed by programmed cell death (apoptosis). One cell type that has a variety of unique cell cycle properties is the horizontal cell of the chicken retina. READ MORE

  4. 2. Cellular Aspects of Lignin Biosynthesis in Xylem Vessels of Zinnia and Arabidopsis

    Author : Henrik Serk; Edouard Pesquet; Simon Hawkins; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin; tracheary elements; xylem wood; post-mortem lignification; non-cell autonomous process; xylem parenchyma; endoreplication; reactive oxygen species; laccases; peroxidases; molecular cell biology; molekylär cellbiologi;

    Abstract : Lignin is the second most abundant biopolymer on earth and is found in the wood (xylem) of vascular land plants. To transport the hydro-mineral sap, xylem forms specialized conduit cells, called tracheary elements (TEs), which are hollow dead cylinders reinforced with lateral secondary cell walls (SCW).

  5. 3. Histone modification regulated bysuppressor of Zeste 12 and Ipl1 : Aurora-like kinase in Drosophila

    Author : Anna Larsson; Umeå universitet; []
    Keywords : molekylär bioteknik inst f molekylärbiologi ; molecular biotechnology dept of molecular biology ;

    Abstract : Polycomb group (PcG) proteins are a group of genome wide silencers that are crucial for many processes during the development. In Drosophila PcG proteins are organised into four different complexes: PRC1, PRC2, PhoRC and PR-DUB. PRC2 consists of four core proteins: Su(z)12, E(z), Esc and Nurf. READ MORE
