Workshop on DNA repair.

A workshop on DNA repair with emphasis on eukaryotic systems was held, under the auspices of the EC Concerted Action on DNA Repair and Cancer, at Noordwijkerhout (The Netherlands) 14-19 April 1991. The local organization of the meeting was done under the auspices of the Medical Genetic Centre South-West, The Netherlands (MGC), c/o Department of Radiation Genetics and Chemical Mutagenesis, University of Leiden (The Netherlands). Local organizers were: D. Bootsma (chairman), W. Ferro, J.H.J. Hoeijmakers, A.R. Lehmann, P.H.M. Lohman, L. Mullenders, and A.A. van Zeeland (secretarial assistance: Mrs. C. Escher-van Heerden and Mrs. R. Bontre). Over 190 scientists participated, and the format of the meeting followed that of the 1987 workshop on the 'Molecular Aspects of DNA Repair' (Friedberg et al., 1987). Plenary review talks in the mornings were followed, in the afternoon, by poster viewing in three or four parallel sessions. Groups of 15-20 posters were discussed in detail, and later on, in plenary sessions, chairpersons of the poster discussions reviewed the afternoons' posters. The principal themes of the meeting were the isolation and characterisation of repair genes and proteins, repair in specific sequences, consequences of defective DNA repair, and new methods for detecting DNA damage and repair. Remarkable progress has been made recently in all of these areas, and many exciting new results were presented. It is impossible to summarize all contributions to this (intensive) one-week meeting. Therefore, and for the sake of coherence, presentations that did not fit easily into any of the general themes of the meetings have not been included
