Research Narrative
Cell cycle deregulation is a hallmark of cancer. The Sanidas laboratory investigates how cancer cells bypass cell cycle control to uncover vulnerabilities that can be targeted for new therapeutic strategies. Our research focuses on the retinoblastoma (RB) tumor suppressor protein, a key regulator of cell division. In healthy cells, RB prevents unnecessary cell proliferation, but in many cancers, its function is turned off by proteins called cyclin-dependent kinases (CDKs). Although RB is a universal regulator of the cell cycle, RB loss is more common in certain tumors, and CDK inhibitors benefit only a subset of patients. The Sanidas laboratory aims to understand the molecular complexity of RB function and identify the context-specific implications of RB inactivation across human cancers. Our goal is to maximize the clinical potential of the recently developed selective CDK inhibitors and guide the development of next-generation targeted therapies that restore or mimic RB’s tumor-suppressive activity.
