Interactions between living cells and nanoparticles are extensively studied to enhance the delivery of therapeutics. Nanoparticles size, shape, stiffness, and surface charge are regarded as the main features able to control the fate of cell-nanoparticle interactions. However, the clinical translation of nanotherapies has so far been limited, and there is a need to better understand the biology of cell-nanoparticle interactions. This study investigates the role of cellular mechanosensitive components in cell-nanoparticle interactions. It is demonstrated that the genetic and pharmacologic inhibition of yes-associated protein (YAP), a key component of cancer cell mechanosensing apparatus and Hippo pathway effector, improves nanoparticle internalization in triple-negative breast cancer cells regardless of nanoparticle properties or substrate characteristics. This process occurs through YAP-dependent regulation of endocytic pathways, cell mechanics, and membrane organization. Hence, the study proposes targeting YAP may sensitize triple-negative breast cancer cells to chemotherapy and increase the selectivity of nanotherapy. The inhibition of Yeas-associated protein (YAP) in TNBC cells affects the organization of plasma membrane, reduces the extracellular matrix (ECM) deposition, impacts their adhesion ability, and increases the endocytosis rate. Thus, targeting cell mechanobiology may be leveraged to optimize cell-nanoparticle interactions. Ultimately, these changes contribute cooperatively to promote the delivery of nanomedicines to cancer cells and improve the therapeutic efficiency.image
