Imprinted small non-coding RNAs

Presentation

Our research focuses on hundreds small noncoding RNAs belonging to the microRNA and C/D snoRNA families. These genes map to chromosomal regions regulated by genomic imprinting, an epigenetic phenomenon by which a few genes are mono-allelically expressed in a parent-of-origin specific manner. The rationale of our research is to explore the impact of recently evolved, imprinted small RNA genes on the evolution, expression and function of mammalian genomes, including in pathological contexts such as the Prader-Willi syndrome.
