Abstract: Our research focuses on the fundamental role of cell-cell and cell-extracellular matrix crosstalk in maintaining tissue homeostasis. During tumour development, these pathways are altered and trigger the formation of environments that are physically and biochemically more conducive to cancer growth. Recently, we showed that expression of a motor protein MYO10, and MYO10-dependent filopodial extensions, while detrimental in invasive breast cancer and associated with poor patient survival, is protective at the early stage. In pre-invasive ductal carcinoma in situ (DCIS), MYO10 maintains a continuous basement-membrane border around the tumours and prevents dissemination into the surrounding stroma. Therefore, any therapeutic targeting of MYO10 must consider the dual actions of this motor protein and cancer stage. In another work (unpublished), we employed microfluidics to mimic cancer cell interaction with the vasculature (endothelial cell layer) under flow. We found that the method used by cancer cells to cross the endothelial cell barrier differs across cell types but is dependent on cancer-cell–endothelial-cell interaction, often involving the extension of filopodia-like protrusions. We are now employing single-cell mass CyToF and other innovative techniques to understand the molecular details of this interaction and identify a potential therapeutic target.
