Abstract: | Purpose The proteinase-activated receptor-2 (PAR2), a member of a newly discovered G protein–coupled receptor subfamily has recently been shown to promote hepatocellular carcinoma
(HCC) cell invasion, suggesting a function in HCC progression. In this study, the effect of PAR2 on intracellular calcium and its involvement in p42/p44 MAPKinase activation in HEP-3B cells and in two primary HCC cultures
established from surgically resected HCC specimens has been investigated. |
