Integrin α6 and EGFR Signaling Converge at Mechanosensitive Calpain 2

Introduction Introduction Materials and Methods Results Discussion Conclusions Author Contributions Conflict of Interest References Carcinoma progression is associated with deposition of ECM that stiffens the local microenvironment [1, 2]. This tissue stiffening results in deposition of additional matrix proteins, initiating a positive feedback loop between cells and the evolving stroma [3]. Cells sense and respond to the stiffness of their environment via RhoA GTPase activation, which feeds back to increase cell contractility via activation of myosin light chain kinase [4]. These ECM-driven changes in cytoskeletal tension regulate motility in a cell-type specific manner [5]. In vi ...
