DNA Organization and Survival Under Stress

A. Chromatin in starved cells

  1. High-resolution cryo-electron microscopy and electron tomography are used to investigate the structural changes that occur within cells following exposure to harsh environmental conditions and starvation. The aims of these studies are to understand the morphological factors that allow survival under stress.
  2. Using electron crystallography and single-particle reconstruction techniques, we are investigating the structures of proteins that are involved in DNA protection against drugs and oxidative agents, and hence enhance survival.
B. Chromatin organization in human sperm cells and fertility

DNA organization within sperm cells ('normal' and those obtained from patients treated with chemotherapy) and its effects upon fertility are being investigated.
