Oncogenic role and therapeutic target of transient receptor potential melastatin 7 channel in malignancy

Area of Science:

• Oncology
• Molecular Biology
• Ion Channel Physiology

Background:

• The Transient Receptor Potential (TRP) superfamily, including TRPM7, influences cancer hallmarks like differentiation, migration, invasion, and chemoresistance.
• TRPM7, a unique ion channel with serine/threonine kinase activity, is linked to proliferation, survival, and progression in various cancers, including breast and pancreatic cancer.
• Elevated TRPM7 expression correlates with poor clinicopathological parameters, such as tumor grade and proliferation index, impacting patient survival.

Purpose of the Study:

• This review synthesizes recent findings on aberrant TRPM7 channel function in tumor progression and angiogenesis.
• It explores TRPM7's role in mediating Ca²⁺ and Mg²⁺ influx and its kinase activity in tumor development.
• The review also addresses TRPM7's involvement in stem cells, cancer stem cells, and its potential as a therapeutic drug target.

Main Methods:

• Literature review focusing on recent advancements in TRPM7 channel function and cancer.
• Analysis of signaling pathway crosstalk involving TRPM7.
• Discussion of TRPM7's channel and kinase activities in tumor development.

Main Results:

• TRPM7 channel function and kinase activity are critical in promoting tumor progression and angiogenesis.
• TRPM7 is involved in the complex interplay of signaling pathways that drive cancer development.
• The channel plays a role in stem cell populations and cancer stem cells, highlighting its significance in tumorigenesis.

Conclusions:

• A deeper understanding of TRPM7's structure, function, and regulation is essential for effective cancer treatment.
• Elucidating TRPM7's crosstalk with oncogenic signals will facilitate the development of new therapeutic strategies.
• Targeting TRPM7 offers potential for novel combinatory therapeutic approaches in cancer treatment.
