Forschungsinteressen

  • Die frühesten Schritte in der DNA Reparatur (P. Grigaravicius)
  • Gen- versus Proteinexpression beim Altern und bei Krebs (M. Radeva, F. Jahns, A. Wilhelm)
  • Veränderung der Genexpression bei Krebs: Vergleich vieler Gewebstypen (K.O. Greulich)
  • Molekültransport an Mikrotubuli, Hindernisse und ihre Rolle beim Altern (K. Böhm, K. Dreblow)
  • Regulation des Blutdrucks (S. Monajembashi, M. Hoffmann)
  • Die Natur des Lichts und der Welle-Teilchen-Dualimus

Neuere Ergebnisse

  • XRCC4 greift sehr früh in die Reparatur von DNA Doppelstrangbrüchen ein
  • Genexpression kann Proteinexpression nicht zuverlässig vorhersagen
  • Überraschend wenige Gene sind generell bei Krebs überexprimiert
  • Hindernisse auf Mikrotubuli bremsen den Molekültransport und sind evtl. an der Genese neurodegenerativer Erkrankungen beteiligt
