The Hippo pathway and human cancer

Area of Science:

• Oncology
• Cell Biology
• Molecular Biology

Background:

• The Hippo pathway is crucial for controlling organ size across species.
• Deregulation of the Hippo pathway is implicated in various cancers, including lung, colorectal, ovarian, and liver carcinomas.
• Despite its role in cancer, mutations in Hippo pathway genes are rare, with only neurofibromin 2 (NF2) established as a tumor suppressor gene.

Purpose of the Study:

• To review the evidence supporting the Hippo pathway as a cancer signaling network.
• To discuss the biological functions of the Hippo pathway relevant to cancer.
• To explore mechanisms of Hippo pathway alteration in cancer and potential therapeutic strategies.

Main Methods:

• Literature review of existing research on the Hippo pathway and cancer.
• Analysis of evidence linking Hippo pathway dysregulation to tumorigenesis.
• Synthesis of information on cancer-relevant biological functions and therapeutic approaches.

Main Results:

• The Hippo pathway plays a significant role in cancer development and progression.
• Alterations in Hippo pathway activity, beyond direct mutations, are key to its oncogenic potential.
• Emerging therapeutic strategies targeting the Hippo pathway show promise.

Conclusions:

• The Hippo pathway is a critical cancer signaling network with diverse biological functions.
• Understanding the mechanisms of Hippo pathway dysregulation is essential for developing effective cancer therapies.
• Targeting the Hippo pathway represents a promising avenue for future cancer treatment.
