In embryos and in human tumors, the expression of the ETSI transcription factor correlates with the occurrence of invasive processes. Although this was demonstrated in cells of mesodermal origin, the expression of ETSI was not detected in epithelial cells. In the present study, we show that during early organogenesis in the chick embryo, ETSI mRNA(More)
To determine the physiological processes in which the transcription factor c-Rel may act, we have examined its pattern of expression in the avian embryo by in situ hybridization. These studies showed that c-rel is expressed ubiquitously at low levels and at high levels in isolated cells undergoing programmed cell death by apoptosis or autophagocytosis. To(More)
Transcription factors of the Rel/NF-kappaB family are widely involved in the immune system. In this study, we investigate the in vivo expression of the avian protein c-Rel in the T-cell lineage during thymus development. The majority of thymocytes do not express the c-Rel protein. However, lymphocyte precursor cells that colonize the thymus express the(More)
Copepods are small crustaceans capable to survive in various aquatic environments. Their responses to changes in different external factors such as salinity and temperature can be observed at different integration levels from copepod genes to copepod communities. Until now, no thorough observation of the temperature or salinity effect stresses on copepods(More)
BACKGROUND Given that advances in research continuously raise new ethical issues, a multidisciplinary working group of investigators involved in biomedical research has gathered to discuss and compare ethical viewpoints in their daily practice. METHODS The working group has drafted a Charter for Ethics in Biomedical Research that encompasses all the steps(More)
