Abstract

Prostate cancer (PCa) is a silent neoplasm and if diagnosed in its early stages, has high chances of cure. Thus, it is necessary to search for rapid detection methods and new prognostic markers for PCa. In this context, the development of techniques that allow the control of cell adhesion on the surface of substrates is a determining factor for the construction of biomaterials applicable in the biomedical field. A recent study, developed at the Laboratory of Engineering and Chemistry of Products (LEQUIP), explored the interaction between CD44 receptors, expressed in specific cell types, and the hyaluronic acid (HA) molecule in coatings able to promote a selective capture of prostatic tumor cells. CD44 is an extracellular glycoprotein involved in multiple cellular processes (including cell adhesion), and its principal ligand is HA. Using the Layer-by-layer (LbL) technique, a very versatile and low-cost functionalization method, these coatings point to promising possibilities for the development of rapid diagnostic platforms. To reach this goal, it is necessary to establish strategies that explore the biological functionality of nanometric coatings. In this context, the use of the tools of synthetic biology represents innovative ideas for the production of new materials. In this project, it is aimed at the synthesis of recombinant proteins, the expertise of Prof. Brad Olsen from MIT, aiming at the production of new materials exploring the LbL technique. It is expected to promote the incorporation of proteins with biofunctional ligands to the coatings and to evaluate the potential of these new materials for cell adhesion and selective release of drugs. The design of these new materials, combining the versatility of the LbL technique with the biological functionality of synthetic proteins, approaches the frontiers of the knowledge of two different fields of research, making possible the development of coatings for applications of biomedical interest.
