TRA2B and infection: The expression levels of genes involved in mRNA processing, such as editing/splicing (Celf2, Cpeb4, Ddx23, Prpf4og, U2af2, Sf3b1, Tra2b), stability (Csdel, Ddx6, Smg1) and export (Hnrnpao, Hnrnpr) were also significantly decreased in the presence of infection, as were many genes involved in transcription initiation.
