520 | a Background: Chemotherapeutic efficacy can be improved by targeting the structure and function of the extracellular matrix (ECM) in the carcinomal stroma. This can be accomplished by e.g. inhibiting TGF beta 1 and -beta 3 or treating with Imatinib, which results in scarcer collagen fibril structure in xenografted human KAT-4/HT29 (KAT-4) colon adenocarcinoma.Methods: The potential role of a(v)beta(6) integrin-mediated activation of latent TGF-beta was studied in cultured KAT-4 and Capan-2 human ductal pancreatic carcinoma cells as well as in xenograft carcinoma generated by these cells. The monoclonal a(v)beta(6) integrin-speafic monoclonal antibody 3G9 was used to inhibit the a(v)beta(6) integrin activity.Results: Both KAT-4 and Capan-2 cells expressed the a(v)beta(6) integrin but only KAT-4 cells could utilize this integrin to activate latent TGF-beta in vitro. Only when Capan-2 cells were co-cultured with human F99 fibroblasts was the integrin activation mechanism triggered, suggesting a more complex, fibroblast-dependent, activation pathway. In nude mice, a 10-day treatment with 3G9 reduced collagen fibril thickness and interstitial fluid pressure in KAT-4 but not in the more desmoplastic Capan-2 tumors that, to achieve a similar effect, required a prolonged 3G9 treatment. In contrast, a 10-day direct inhibition of TGF-beta 1 and -beta 3 reduced collagen fibril thickness in both tumor models.Conclusion: Our data demonstrate that the a(v)beta(6)-directed activation of latent TGF-beta plays a pivotal role in modulating the stromal collagen network in carcinoma, but that the sensitivity to a(v)beta(6) inhibition depends on the simultaneous presence of alternative paths for latent TGF-beta activation and the extent of desmoplasia. | |
