We are studying tumour suppressor genes in<br />

normal and neoplastic cells. These genes, whose<br />

function is altered in a large number <strong>of</strong> tumours,<br />

have a fundamental role in <strong>the</strong> cycle cycle, in<br />

cellular differentiation, cellular aging or in <strong>the</strong><br />

response to genotoxic agents.<br />

We are using C. elegans in order to better<br />

understand <strong>the</strong> function <strong>of</strong> <strong>the</strong>se genes and <strong>the</strong>ir<br />

position within complex signalling pathways.<br />

We will more particularly study homologues in<br />

C. elegans <strong>of</strong> <strong>the</strong> genes BTG-1, BTG-2, FRG-1,<br />

FVT-1 and <strong>of</strong> known interacting proteins. The<br />

C. elegans homologue <strong>of</strong> BTG-1 and BTG-2 is<br />

fog-3. Preliminary results will be presented and<br />

discussed.
