Multiple promoter elements required for leukemia inhibitory factor-stimulated M2 muscarinic acetylcholine receptor promoter activity.

Treatment of neuronal cells with leukemia inhibitory factor (LIF) results in increased M(2) muscarinic acetylcholine receptor promoter activity. We demonstrate here that multiple promoter elements mediate LIF stimulation of M(2) gene transcription. We identify a LIF inducible element (LIE) in the M(2) promoter with high homology to a cytokine-inducible ACTG-containing sequence in the vasoactive intestinal peptide promoter.
