Deregulation and Therapeutic Potential of the Hippo Pathway in Cancer

The Hippo pathway has drawn increasing interest in the past decade for its role in the regulation of cell growth, differentiation, organ size, and tissue homeostasis. Recent studies have expanded our knowledge of known upstream regulators of the Hippo pathway and have consistently demonstrated that the Hippo pathway is critical for translating cellular cues into transcriptional responses by receiving input from a wide range of upstream signals. Dramatic overgrowth phenotypes upon deregulation of the Hippo pathway have prompted investigation into its role in cancer. Here we provide an overview of the Hippo pathway, our current understanding of its role in tumorigenesis, and potential therapeutics targeting Hippo signaling.
