Scientific Interest(s):

Dr. Robert Schiestl's work focuses on basic mechanisms, genetic control and inducibility by carcinogens of homologous and illegitimate recombination, as well as molecular events involved in carcinogenesis. Experiments are carried out in yeast, human cells and in transgenic mice.

Current projects include determining inter-individual differences in DNA double-strand break repair efficiency in cells from radiation sensitive cancer patients with the aim of ultimately identifying new genes affecting cancer predisposition; determining the effects of mutations in DNA repair and DNA damage sensing genes such as Atm, p53, p21, Gadd45, rad52, Ku80, DNAPk, Ogg1, Myh, Bloom and Werner syndrome on spontaneous and carcinogen-induced genetic instability in mice; and determining basic mechanisms, genetic control and inducibility by carcinogens of DNA deletions, and illegitimate recombination in the yeast Saccharomyces cerevisiae.
