Small molecules, big role: snoRNAs in gene regulation

Eötvös Loránd University
Peer-Reviewed Publication

Small nucleolar RNAs (snoRNAs) are non-coding RNA molecules whose role in gene regulation and their association with certain diseases, such as inflammatory bowel disease (IBD) or colorectal cancer, has only recently become known. The Fish Genetics Research Group of the Department of Genetics at ELTE has investigated in detail the temporal expression of snoRNAs in the genome of zebrafish, an important genetic model organism, and has also created an online database (snoDanio) for their interactive visualization.
