Nicotine 0-8 proopiomelanocortin Homo sapiens 51-70 21653710-3 2011 Here we address the hypothesis that if weight-reducing actions of nicotine are mediated by anorexigenic proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus, nicotine should excite these cells. Nicotine 66-74 proopiomelanocortin Homo sapiens 104-123 21653710-3 2011 Here we address the hypothesis that if weight-reducing actions of nicotine are mediated by anorexigenic proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus, nicotine should excite these cells. Nicotine 66-74 proopiomelanocortin Homo sapiens 125-129 21653710-3 2011 Here we address the hypothesis that if weight-reducing actions of nicotine are mediated by anorexigenic proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus, nicotine should excite these cells. Nicotine 176-184 proopiomelanocortin Homo sapiens 104-123 21653710-3 2011 Here we address the hypothesis that if weight-reducing actions of nicotine are mediated by anorexigenic proopiomelanocortin (POMC) neurons of the hypothalamic arcuate nucleus, nicotine should excite these cells. Nicotine 176-184 proopiomelanocortin Homo sapiens 125-129 21653710-4 2011 Nicotine at concentrations similar to those found in smokers, 100-1,000 nM, excited POMC cells by mechanisms based on increased spike frequency, depolarization of membrane potential, and opening of ion channels. Nicotine 0-8 proopiomelanocortin Homo sapiens 84-88 21653710-7 2011 Nicotine exerted similar actions on POMC and NPY cells, with a slightly greater depolarizing action on POMC cells. Nicotine 0-8 proopiomelanocortin Homo sapiens 36-40 21653710-7 2011 Nicotine exerted similar actions on POMC and NPY cells, with a slightly greater depolarizing action on POMC cells. Nicotine 0-8 proopiomelanocortin Homo sapiens 103-107 21653710-13 2011 Together, these results indicate that nicotine has a number of similar actions, but also a few different actions, on POMC and NPY neurons that could contribute to the weight loss associated with smoking. Nicotine 38-46 proopiomelanocortin Homo sapiens 117-121
