Amphiregulin Exosomes Increase Cancer Cell Invasion
Autocrine, paracrine, and juxtacrine are recognized modes of action for mammalian EGFR ligands including EGF, TGF-α (TGFα), amphiregulin (AREG), heparin-binding EGF-like growth factor (HB-EGF), betacellulin, epiregulin, and epigen. We identify a new mode of EGFR ligand signaling via exosomes. Human breast and colorectal cancer cells release exosomes containing full-length, signaling-competent E...
متن کاملP-cadherin promotes cell-cell adhesion and counteracts invasion in human melanoma.
Malignant transformation of melanocytes frequently coincides with alterations in epithelial cadherin (E-cadherin) expression, switching on of neural cadherin (N-cadherin), and, when progressed to a metastatic stage, loss of membranous placental cadherin (P-cadherin). In vitro studies of melanoma cell lines have shown invasion suppressor and promoter roles for E-cadherin and N-cadherin, respecti...
متن کاملexosomes derived from Rab27a-overexpressing cells elicited more potent antitumor immunity. A Rab27a-overexpressing line was established via transfection of a Rab27a overexpression vector into the human non-small-cell lung cancer cell line, A549. Exosomes
Lung cancer is the leading cause of mortality worldwide. However, there is a lack of effective therapeutic strategies. Currently, tumor immunotherapy based on exosomes, which are secreted by a variety of cell types including tumor cells, has drawn particular attention and are suggested to have the potential for exploitation in tumor therapy. Nevertheless, the therapeutic efficacy mediated via t...
متن کاملSOX4 promotes melanoma cell migration and invasion though the activation of the NF-κB signaling pathway
SOX4 has been reported to be abnormally expressed in many types of cancer, including melanoma. However, its role in cell proliferation and metastasis remains controversial. In this study, SOX4 was downregulated or overexpressed in A375, A2058 and A875 melanoma cells by siRNA or lentivirus transfection, respectively. Cell metastasis was observed by Transwell assay. In an aim to elucidate the und...
متن کاملNotch signaling promotes growth and invasion in uveal melanoma.
PURPOSE To determine whether uveal melanoma, the most common primary intraocular malignancy in adults, requires Notch activity for growth and metastasis. EXPERIMENTAL DESIGN Expression of Notch pathway members was characterized in primary tumor samples and in cell lines, along with the effects of Notch inhibition or activation on tumor growth and invasion. RESULTS Notch receptors, ligands, ...
