title: The effect of mizolastine on expression of vascular endothelial cell growth factor, tumour necrosis factor-alpha and keratinocyte-derived chemokine in murine mast cells, compared with dexamethasone and loratadine.
abstract: It has been shown that many antihistamines may have anti-inflammatory activity in addition to being H1 antagonists. Mizolastine (MIZ), a novel antihistamine, might also have anti-angiogenesis properties. In this study, we investigated the influence of MIZ on proangiogenesis factors, vascular endothelial cell growth factor (VEGF), tumour necrosis factor (TNF)-alpha and keratinocyte-derived chemokine (KC) in murine mast cells by using ELISA and RT-PCR, as compared with dexamethasone (DEX) and loratadine (LOR). Our results show that MIZ is effective in the inhibition of KC, VEGF and TNF-alpha release induced by an IgE-dependent mechanism, in a time- and dose-dependent manner. The differences between the inhibitory effects of the three drugs on these proangiogenic factors were rather subtle. Semiquantitative analysis using RT-PCR showed that the three drugs significantly reduced VEGF165, VEGF120, TNF-alpha and KC mRNA expression. Statistical results revealed that the effect of DEX on VEGF165 mRNA was different from that of MIZ or LOR (P < 0.01) and the differences between the three drugs on VEGF120, TNF-alpha and KC mRNA were not statistically significant (P > 0.05). These findings raise the possibility that MIZ can mediate anti-angiogenesis activity and that the effect may depend not only on the inhibition on the levels of cytokine proteins but also at the mRNA level.
