GATA3 and psoriasis: The factors controlling keratinocyte hyperproliferation and the disturbedkeratinocyte differentiation in psoriasis remain incompletely understood.Hyperproliferation in psoriasis and proliferation in cancers share manycharacteristics, such as the induction of similar oncogenes and transcriptionfactors [3].Previous microarray studies assessing altered biological pathways in psoriasisconsistently showed that mRNA encoding the transcription factor GATA3 wassignificantly downregulated in lesional psoriatic keratinocytes, and was re-inducedby successful therapy [4], [5].
