ERBB2 and influenza: These pathways included categories such as phospholipid metabolism (Glycerophospholipid biosynthesis), signaling by receptor tyrosine kinases (Signaling by ERBB2/4), gene expression (DNA Methylation and Transcriptional Repression Signaling), post-translational protein modification (Phosphorylation), and cell cycle regulation (Cell Cycle Control of Chromosomal Replication), all of which have been associated with influenza infection previously (70, –, 74).
