Dr Laura Smith, at the Leeds Institute of Molecular Medicine, University of Leeds, has been awarded a pilot grant by Breast Cancer Campaign, to study why some types of breast cancers are difficult to destroy with radiotherapy. The grant forms part of £2 million awarded to 20 projects in the UK and Ireland.

Dr. Michael Stilmann, Dr. Michael Hinz and Professor Claus Scheidereit have shown that the protein PARP-1, which detects DNA damage within seconds, activates the transcription factor NF-kappaB, a well-known regulator of gene expression. NF-kappaB triggers a survival program, which blocks programmed cell death.
