Nicotine 10-18 signal transducer and activator of transcription 3 Homo sapiens 81-86 20106947-4 2010 The objective of this study was to identify the role of Stat3 in chemoresistance induced by nicotine in human bladder cancer cell line, T24 cells. Nicotine 92-100 signal transducer and activator of transcription 3 Homo sapiens 56-61 20106947-8 2010 We provide evidence for the first time that nicotine strongly activated Stat3, leading to Cyclin D1 overexpression, cell cycle perturbations, and chemoresistance. Nicotine 44-52 signal transducer and activator of transcription 3 Homo sapiens 72-77 20106947-9 2010 Furthermore, nicotine mobilized Stat3 signaling, resulting in the loss of extracellular signal-regulated protein kinase 1/2 (ERK 1/2) activation and reduced chemosensitivity via nicotinic acetylcholine receptors and beta-adrenoceptors. Nicotine 13-21 signal transducer and activator of transcription 3 Homo sapiens 32-37
