In the present study, a cytotoxin-positive H. pylori was used to infect and examined for its effect on the stimulation of second messengers in human gastric adenocarcinoma (AGS). Results showed that H. pylori increased cytosolic free calcium concentration [Ca2+]i in host cells in a dose-dependent manner. The increase of [Ca2+]i was due to release from the intracellular Ca2+ store as well as entry to the extracellular Ca2+. H. pylori infection on host cells was also found to induce the generations of inositol phosphates, adenosine 3~, 5~-cyclic monophosphate, and guanosine 3~,5~-cyclic monophosphate, and to stimulate the secretion of pepsinogen. ------>tmu_sno=None ------>sno=1798 ------>authors2=None ------>authors3=None ------>authors4=None ------>authors5=None ------>authors6=None ------>authors6_c=None ------>authors=Chan EC, Chen CT, Lin YL, Chen KT ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Signaling pathway and pepsinogen secretion in Helicobacter pylori-infected human gastric adenocarcinoma. ------>language=2 ------>check_flag= ------>submit_date= ------>country=None ------>no=4 ------>patent_SDate=None ------>update_bywho= ------>publish_year=1999 ------>submit_flag= ------>publish_month=None |
