Abstract
Buccal mucosa carcinoma-derived cell line, HO-1-N-1, epithelial-like cells, was obtained in order to investigate the characteristics of oral cancer cells and examine the [Ca2+]i responses to stimulants, such as bradykinin (BK), histamine (HIST), thapsigargin (TG), epidermal growth factor (EGF) and transforming growth factor alpha (TGF alpha ). Intracellular Ca2+ influx was observed by all stimulants that enhanced the [Ca2+]i response. However, intracellular Ca2+ release was not observed in response to growth factors. The [Ca2+]i response of BK (100 nM) was inhibited by 10 micro M of the BKB2 antagonist, D-Arg-[Hyp3, Thi5,8, D-Phe7]-BK, and HIST (1 mM) was completely inhibited by 100 nM of the H1 antagonist, (+)-chlorpheniramine, in the presence and absence of extracellular Ca2+ (1.5 mM).
