Let’s Focus on the 98%!
For the lifetime of our species, it’s only yesterday that we found out that the earth is not flat, and a few seconds away that there are thousands of non-coding RNAs with a multitude of functional roles. Until recently, biomedical research was mostly focused on the 2% of the human genome that encodes for proteins. It is currently re-inventing itself in order to understand and harness these fascinating regulatory newcomers.
The RNA revolution has turned junk-DNA into a non-coding RNA (ncRNA) goldmine. Recent breakthroughs have shown how ncRNAs, such as microRNAs (miRNAs) or long non-coding RNAs (lncRNAs), can play important regulatory roles in numerous physiological or pathological processes.
Unfortunately, the lack of functional characterization for most non-coding genomic regions and transcripts impedes their incorporation into translational research.
To this end, we analyze vast datasets, design novel methods and implement algorithms that identify non-coding elements as potential biomarkers and therapeutic targets, as well as facilitate the prioritization of non-coding variants associated with monogenic or complex polygenic traits.
