The extracellular matrix (ECM) is a fundamental component of the tissue of multicellular organisms that is comprised of an intricate network of multidomain proteins and associated factors, collectively known as the matrisome. The ECM creates a biophysical environment that regulates essential cellular processes such as adhesion, proliferation...

Normal tissue homeostasis and architecture restrain tumor growth. Thus, for a tumor to develop and spread, malignant cells must overcome growth-repressive inputs from surrounding tissue and escape immune surveillance mechanisms that curb cancer progression. This is achieved by promoting the conversion of a physiological microenvironment to a...

Endothelial cell interactions with their extracellular matrix are essential for vascular homeostasis and expansion. Large-scale proteomic analyses aimed at identifying components of integrin adhesion complexes have revealed the presence of several RNA binding proteins (RBPs) of which the functions at these sites remain poorly understood. Here,...

Vascular endothelial growth factor (VEGF) is an angiogenic cytokine, which plays a major role in tumor angiogenesis. VEGF mRNA expression is controlled by hypoxia, growth factors and hormones through both transcriptional and post-transcriptional mechanisms. VEGF mRNA has a short half-life and its abundance is regulated by the binding of...

Cellular fibronectin (FN) and tenascin-C (TNC) are prominent development-and disease-associated matrix components with pro-and anti-adhesive activity, respectively. Whereas both are present in the tumour vasculature, their functional interplay on vascular endothelial cells remains unclear. We have previously shown that basally-oriented...
