Presentation Transcript

  1. FANCD2 and its role in FA and other Cancers Christina Miller

  2. Fanconi Anemia is a congenital cancer predisposition syndrome that causes chromosomal instability • Bone marrow failure • Sensitivity to cross-linking agents

  3. FANCD2 is expressed in tissues where proliferation occurs http://dx.doi.org.libproxy.lib.unc.edu/10.1016/S1097-2765(01)00172-1

  4. FANCD2 is regulated by post Translational Modification • Monoubiquitinated on Lys-561 • Necessary for binding to chromatin • Phosphorylated by ATM or ATR on Ser-222 http://dx.doi.org/10.1016/j.mrfmmm.2005.05.010 http://www.scills.ac.uk/arno-alpi-research.shtml

  5. Interstrand Cross-links are covalent bonds that link DNA strands and block replication Frontiers in Bioscience 9, 421-437, January 1, 2004

  6. FANCD2 is necessary for replication-dependent ICL repair https://walter.hms.harvard.edu/node/11 Nature Reviews Cancer3, 23-34 (January 2003)

  7. FANCD2 is also active in S Phase arrest pathway Nature Reviews Cancer 3, 23-34 (January 2003) http://dx.doi.org/10.1016/j.dnarep.2004.04.005

  8. FANCD2-/- mice show phenotypes similar to those of FA patients • FANCD2-/- mutant eye one day after birth • Wild type and FANCD2-/- mutant one day after birth • Wild type eye one day after birth Genes Dev. 2003 August 15; 17(16): 2021–2035.

  9. Reduced FANCD2 expression is correlated with decreased survival of breast cancer patients Am J Pathol. 2010 June; 176(6): 2935–2947.
