Since Jan 2009 - Supervisor of Bruno Miguel

I have been involved in the understanding of the molecular basis of the gastric preneoplastic lesion intestinal metaplasia and intestinal differentiation of gastric carcinomas. We were among the first groups to identify the functional relevance of the transcription factor CDX2 in intestinal metaplasia and we are currently involved in understanding how this protein becomes de novo expressed in the stomach. Transcriptional and post-transcriptional regulatory mechanisms have been identified. Understanding this process is not only likely to increase our knowledge on the normal mechanisms of differentiation but also, since metaplasia is a precursor lesion to gastric cancer, it will increase our possibilities of developing early diagnostic and therapeutic strategies.
