Category:Quantum mechanics Category:Quantum mechanics booksAlteration of the cytoskeleton is a characteristic feature of epithelial-mesenchymal transition (EMT) and has been shown to contribute to metastatic dissemination in many human cancers. However, the signaling mechanisms that regulate EMT and cytoskeletal dynamics during the metastatic cascade have remained largely undefined. The Src family kinase Lyn is frequently overexpressed in human breast cancer and is associated with metastasis. We recently demonstrated that Lyn inhibits breast cancer cell motility and invasion and these actions require its kinase activity. In contrast, we have also demonstrated that Lyn is activated in normal mammary epithelial cells during the initiation of branching morphogenesis in three-dimensional Matrigel cultures, and that a dominant negative Lyn mutant inhibits mammary epithelial branching morphogenesis. Interestingly, Lyn is not activated in normal mammary epithelial cells in the context of two-dimensional culture. This observation suggests that Lyn activity is either differentially regulated or restricted to specific environmental cues or signals. However, it remains to be determined whether Lyn is activated during the initiation of epithelial branching morphogenesis in vivo, and what the role of Lyn in this context is. To investigate the regulation and function of Lyn in mammary epithelial morphogenesis and metastatic dissemination in vivo, we propose to test the following hypotheses: Hypothesis 1: Lyn regulates normal mammary epithelial branching morphogenesis. Hypothesis 2: Lyn regulates invasive potential of breast cancer cells. To address these hypotheses, we will: 1) determine the role of Lyn in normal mammary epithelial branching morphogenesis in vivo using a transgenic approach; 2) determine the role of Lyn in the acquisition of an invasive phenotype by breast cancer cells in vitro; 3) determine the specific signaling pathways through which Lyn regulates mammary epithelial branching morphogenesis and tumor cell invasion in vivo. These studies will provide a greater understanding of the role of Lyn in normal mammary epithelial development and the initiation of metastatic dissemination.The present invention relates to the general field of a construction of a shaft furnace with tuyeres.
