Histamine 105-114 histamine receptor H1 Homo sapiens 128-131 33148907-6 2020 Dexamethasone suppressed basal levels of H1R mRNA, and histamine-induced up-regulation of H1R mRNA and ERK phosphorylation in HeLa cells. Histamine 55-64 histamine receptor H1 Homo sapiens 90-93 33148907-7 2020 These data suggested that corticosteroid inhibited both basal transcription and histamine-induced transcriptional activation of H1R through its suppression of ERK phosphorylation in the signaling pathway involved in H1R gene transcription. Histamine 80-89 histamine receptor H1 Homo sapiens 128-131 33148907-7 2020 These data suggested that corticosteroid inhibited both basal transcription and histamine-induced transcriptional activation of H1R through its suppression of ERK phosphorylation in the signaling pathway involved in H1R gene transcription. Histamine 80-89 histamine receptor H1 Homo sapiens 216-219
