- Abstract:
- We report here the isolation of human zinc finger 2 (HZF2), a putative zinc-finger transcription factor, by motif-directed differential display of mRNA extracted from histamine-stimulated human vein endothelial cells. The expression of HZF2 mRNA in venous endothelial cells was verified by Northern blot analysis, which also revealed an enrichment of HZF2 mRNA in lymphocytes and monocytes. Histamine induced a time- and concentration-dependent upregulation of HZF2 level with a 6-fold peak increase of mRNA at 30 min. HZF2 upregulation was abolished by different NOS isozyme inhibitors. Guanylate cyclase inhibition resulted in a significant decrease of HZF2 expression. These observations indicate HZF2 as a potentially interesting new target for studies concerning rapid NO-mediated gene regulation.
