Recent advances in the molecular genetics of cancer. Second joint conference of the American Association of Cancer Research and the European Association of Cancer Research, Oxford, 9-12 September 1997.
The second joint conference of the AACR and the EACR held in Oxford from 9-12 September 1997 was successful from many vantage points. While providing an optimal setting in which European and American cancer researchers could meet and exchange information, the conference had an excellent scientific programme which encompassed both methodological updates on important models used in cancer research and presentations of recent key advances in the molecular genetics of cancer. Lower eukaryotes are established model organisms used to elucidate fundamental but complex eukaryotic processes, such as those involved in tumorigenesis and cancer progression, and the progressive availability of their genome sequence makes them even more attractive. Transgenic mouse models are increasingly used not only for the study of one gene of interest but for investigation of the interactions among genes involved in the same pathway. The family of tumour suppressor genes is growing fast and several presentations were devoted to recently identified members such as the Von Hippel-Lindau gene, the FHIT gene and the PTEN gene. The systematic analysis of loss of heterozygosity on multiple loci in tumour specimens can provide the basis for preliminary models of molecular multistep progression in some tumour types, even though this is limited by the high degree of complexity found. Mechanisms of cell cycle regulation and apoptosis continue to be dissected and to constitute a fruitful area of investigation, with important recent insights on the p53-MDM2 autoregulatory loop and on the involvement of E2F-1 in apoptosis.
