  1. 16. Regulation of Aurora A activity during checkpoint recovery

    University essay from Institutionen för biologisk grundutbildning

    Author : Yan Zhou; [2012]
    Keywords : AurA activation; G2 checkpoint; checkpoint recovery; Time-lapse FRET microscopy;

    Abstract : Cell division requires accurate DNA replication and cells develop checkpoint mechanisms toensure the correct passage of the genetic material. Cells arrest by a checkpoint when DNAdamage is found. After the checkpoint is silenced, the cell cycle can be resumed. READ MORE

  3. 17. 1,25(OH)2D3 and Initial Regulation of Smad2/3 Activity in PC-3 Prostate Cancer Cells

    University essay from Institutionen för vård och natur

    Author : Anette Stahel; [2009]
    Keywords : prostate cancer; PC-3; vitamin D; 1; 25 OH 2D3; TGFβ; Smad2; Smad3;

    Abstract : The vitamin D metabolite 1,25(OH)2D3 has long been known to inhibit growth of prostate cancer cells and this mainly through a VDR-mediated pathway controlling target gene expression, resulting in cell cycle arrest, apoptosis and differentiation. Another major way in which 1,25(OH)2D3 inhibits cell growth in prostate cancer is via membrane-initiated steroid signalling, which triggers activation of signal cascades upon steroid binding to a receptor complex, leading to induction of genes regulating cell growth, proliferation and apoptosis.

  4. 18. Modification of the plant retinoblastoma-related protein(RBR1) by SUMO : structural and functional studies

    University essay from SLU/Dept. of Forest Genetics and Plant Physiology

    Author : Edward Businge; [2009]
    Keywords : SUMO; Retinoblastoma; Plant protein; Arabidopsis;

    Abstract : The retinoblastoma protein (Rb) is a transcription regulator and key component of theRb/E2F/DP pathway which regulates progression of the cell cycle in plants and animals.Within the pathway, Rb blocks E2F transcriptional activity consequently ensuringrestricted cell proliferation.

  5. 19. 24,25(OH)2D3 and Regulation of Catalase Activity in LNCaP Prostate Cancer

    University essay from Institutionen för vård och natur

    Author : Anette Stahel; [2007]
    Keywords : prostate cancer; proliferation; growth inhibition; vitamin D; 24; 25 OH 2D3; catalase; hydrogen peroxide; H2O2;

    Abstract : The vitamin D metabolite 1,25(OH)2D3 has long been known to inhibit growth of prostate cancer cells and this has been attributed to a VDR-mediated pathway controlling target gene expression, resulting in cell cycle arrest, apoptosis and differentiation. New research has shown that another vitamin D metabolite, 24,25(OH)2D3, inhibits proliferation of prostate cancer cells as well, more specifically, cells of the line LNCaP. READ MORE
