    Calcium Cytotoxicity Sensitizes Prostate Cancer Cells to Standard-of-Care Treatments for Locally Advanced Tumors

    Scientists demonstrated that selective agonists of Transient Receptor Potential cation channel subfamily M member 8, a cation channel characteristic of the prostate epithelium frequently overexpressed in advanced stage III/IV prostate cancers (PCa), sensitize therapy refractory models of PCa to radio, chemo or hormonal treatment.

    Abstract

    Enzalutamide Response in a Panel of Prostate Cancer Cell Lines Reveals a Role for Glucocorticoid Receptor in Enzalutamide Resistant Disease

    Representative in vitro model systems that accurately model response to therapy and allow the identification of new targets are important for improving the treatment of prostate cancer. Scientists described molecular characterization and drug testing in a panel of 20 prostate cancer cell lines.

    Integrin α2β1 Inhibition Attenuates Prostate Cancer Cell Proliferation by Cell Cycle Arrest, Promoting Apoptosis and Reducing Epithelial-Mesenchymal Transition

    Investigators examined the effects of the inhibitor BTT‐3033, which selectively interferes with the connection between integrin a2b1 and its ligand, on migration, epithelial–mesenchymal transition, cell cycle arrest, apoptosis, and specific intracellular signaling pathways using LNcap‐FGC and DU‐145 prostate cancer cell lines.
