Cellular and molecular mechanisms implicated in the dual role of ROR2 in cancer

Area of Science:

• Oncology
• Molecular Biology
• Cancer Signaling

Background:

• ROR1 and ROR2 are Wnt receptors crucial for Wnt pathways independent of beta-catenin.
• These receptors are implicated in tumor progression, including proliferation, survival, invasion, and therapy resistance.
• ROR1 consistently promotes tumorigenesis, whereas ROR2 exhibits context-dependent roles in cancer.

Purpose of the Study:

• To summarize ROR2 expression patterns in cancer patients and their correlation with clinical outcomes.
• To review the biological processes and signaling pathways modulated by ROR2, explaining its dual role in cancer.
• To outline current strategies for targeting ROR2 in cancer therapy.

Main Methods:

• Review of existing literature on ROR2 expression and function in various cancer types.
• Analysis of clinical data linking ROR2 expression levels to patient prognosis.
• Exploration of signaling pathways and biological mechanisms underlying ROR2's oncogenic or tumor-suppressive activities.

Main Results:

• ROR2 expression varies significantly across different cancer types and patient cohorts.
• ROR2 can act as an oncoprotein or a tumor suppressor depending on the specific cancer context.
• Specific signaling pathways and molecular interactions dictate ROR2's opposing roles in tumorigenesis.

Conclusions:

• ROR2 presents a complex therapeutic target due to its dichotomous role in cancer.
• Understanding ROR2's context-specific functions is essential for developing effective targeted therapies.
• Ongoing research focuses on elucidating ROR2-mediated pathways to optimize cancer treatment strategies.
