Forskningsinteresser

The main focus of my research is within the field of non-coding RNAs and cancer. The class of non-coding RNAs have promising potential as novel targets for cancer therapy, and for this reason it is important to acquire more knowledge about the basic function of these RNA species. Some of the research project I have been involved in have shed light on the accuracy of methods for performing small RNA profiling, have identified important cancer associated miRNAs in neuroblastoma and meningioma, and have identified the small RNA content in exosomes from breast cancer cells in order to unravel their potential as biomarkers. Currently I'm focusing on the role of long non-coding RNAs in epithelial to mesenchymal transition and unraveling the functional role of the long non-coding RNA NEAT1 in breast cancer.
