The new research focuses on a critical cellular step that is part of the process, known as RNAdegradation.

He found this suppression of host gene expression, and then he designed several elegant experiments that showed it was caused by RNAdegradation, something never before seen in an RNA virus.
The down-regulated genes can be divided in five classes:protein degradation, RNA transcription, cell wall synthesis and degradation, kinase receptor and peptide transport.
