Quinn et al. published that LPS-induced expression of transcription factor E26 transformation-specific 2 (Ets2) is responsible for induction of miR 155 expression, but also the NF-κB and mitogen-activated protein kinase (MAPK) pathway, which is activated during LPS infection, stimulates the expression of miR 155 [58]. This evidence concerns the gene ETS2 and van der Woude syndrome.
