Targeting ErbB3-mediated stromal–epithelial interactions in pancreatic ductal adenocarcinoma

Abstract: Background:We sought to investigate the role of ErbB3-mediated signalling on the interaction between pancreatic cancer-associated fibroblasts (CAF) and carcinoma cells in an effort to disrupt tumourigenic pancreatic ductal adenocarcinoma (PDAC) stromal–epithelial cross-communication.Methods:Primary CAF cultures were established from human PDAC surgical specimens. AsPC-1 pancreatic cancer cell murine subcutaneous xenografts were developed in the presence and absence of CAF and were subsequently treated with epi… Show more

“…Our data are consistent with previous reports of low NRG1 expression in melanoma cells (20) and with studies demonstrating the presence of NRG1 in skin fibroblasts (34) and CAFs from pancreatic ductal adenocarcinoma (35). However, concurrent expression of ErbB3 and NRG1 may exist in a subset of human metastatic melanomas (36), and, in these tumors, direct targeting of ErbB3/ErbB2 may be efficacious (37).…”

“…CAFs provide protumorigenic signals that lead to increased tumor growth via the stimulation of tumor cell proliferation and angiogenesis as well as the formation of metastases by the enhancement of the migratory and invasive potential of the tumor cells (18)(19)(20)(21)(22)(23)(24)(25). As a number of publications suggest that CAFs could also modulate the drug sensitivity of cancer cells (26)(27)(28)(29)(30)(31)(32)(33)(34), this study was undertaken to evaluate the influence of CAFs on the cetuximab response in HNSCC cell lines.…”

“…En effet, la plupart de ces mutations se situent dans le domaine extracellulaire et confèrent un potentiel oncogénique à la molécule. L'activation du récepteur HER3 dépendante de la NRG intervient dans certains cancers, soit par une boucle autocrine mise en évidence dans le cancer de l'ovaire [5], le cancer de la tête et du cou sans amplification de HER2 [6] ou le cancer colorectal [7], soit par une boucle paracrine de sécrétion via les fibroblastes du microenvironnement dans le cancer du pancréas [8] pancréatique [17]. Un premier essai clinique (NCT00923299) d'association cétuximab/trastuzumab, administrée en seconde ligne chez 33 patients atteints de carcinome pancréatique progressant sous gemcitabine, a conduit à une stabilisation de la maladie chez 27 % des patients, avec une corrélation significative entre la toxicité cutanée et la survie sans progression [18].…”
