Summary

Our group is interested in post-transcriptional regulation during embryo development and disease. In particular, we investigate how RNA-binding proteins (RBPs) regulate translation and how this is connected with general cell homeostasis and cancer progression. During this year, we have identified new RBPs with roles in melanoma progression, and are currently investigating their molecular mechanisms of action. In collaborative work, we have also contributed to expand the roles of the RBP UNR/CSDE1 in preventing stem cell differentiation, and have evaluated its potential as a biomarker for pancreatic cancer outcome.
