[Research progress of Merlin protein and its signal pathway in tumor]

Area of Science:

• Cell Biology
• Molecular Biology
• Oncology

Background:

• The Hippo signaling pathway regulates cell proliferation, apoptosis, and organ size in multicellular organisms.
• While the core kinase cascade is well-studied, upstream regulatory mechanisms, particularly protein interactions, remain less understood.
• Merlin (NF2), a FERM domain protein, has emerged as a potential upstream component of the Hippo pathway.

Purpose of the Study:

• To review the recent research progress on Merlin (NF2) protein.
• To elucidate the relationship between Merlin (NF2) and malignant tumors.
• To understand Merlin's role as an upstream regulator in the Hippo signaling pathway and its implications in cancer.

Main Methods:

• Literature review of recent studies on Merlin (NF2) and the Hippo signaling pathway.
• Analysis of research on Merlin's function in cell proliferation, apoptosis, and organ size regulation.
• Examination of studies linking Merlin mutations/deletions to oncogene expression and tumor progression.

Main Results:

• Merlin (NF2) functions as an upstream regulatory molecule in the Hippo signaling pathway.
• Mutations or deletions in Merlin (NF2) can lead to increased expression of oncogenes like Yap/Yki.
• This dysregulation contributes to tumor progression and negatively affects patient prognosis.

Conclusions:

• Merlin (NF2) plays a critical role in the Hippo signaling pathway and its association with cancer development.
• Understanding Merlin's function is crucial for developing strategies for cancer prevention and treatment.
• Further research into Merlin (NF2) will enhance our knowledge of its oncogenic potential and therapeutic targets.
