Methacholine Chloride 38-50 carbonic anhydrase 2 Homo sapiens 115-118 2663854-7 1989 In the absence of extracellular Ca2+, pretreatment with methacholine, an agonist believed to mobilize Ca2+ through the production of inositol 1,4,5-trisphosphate, inhibited but did not completely block the response to thapsigargin; likewise, pretreatment with thapsigargin inhibited the response to methacholine. Methacholine Chloride 56-68 carbonic anhydrase 2 Homo sapiens 102-105 2663854-11 1989 These results demonstrate that the mechanisms for activation of Ca2+ entry by thapsigargin and methacholine are the same and are consistent with the idea that entry is initiated by the depletion of the intracellular inositol 1,4,5-trisphosphate-sensitive Ca2+ pool. Methacholine Chloride 95-107 carbonic anhydrase 2 Homo sapiens 64-67 2663854-10 1989 In intact cells, methacholine and thapsigargin together produced a greater initial release of Ca2+ than either alone, but they were not additive in the sustained phase of Ca2+ mobilization.
