1 nAChRs-ERK1/2-Egr-1 signaling participates in the developmental toxicity of nicotine by epigenetically down-regulating placental 11beta-HSD2. Nicotine mitogen-activated protein kinase 3 Homo sapiens
2 In human BeWo cells, nicotine decreased 11beta-HSD2 expression, increased nAChRalpha9 expression, and activated ERK1/2/Elk-1/Egr-1 signaling in the concentration (0.1-10 muM)-dependent manner. Nicotine mitogen-activated protein kinase 3 Homo sapiens
3 Antagonism of nAChRs, inhibition of ERK1/2 and Egr-1 knockdown by siRNA were able to block/abrogate the effects of nicotine on histone modification and expression of 11beta-HSD2. Nicotine mitogen-activated protein kinase 3 Homo sapiens
