Cancer hallmarks intersect with neuroscience in the tumor microenvironment

Area of Science:

• Oncology
• Neuroscience
• Cancer Biology

Background:

• Tumorigenesis involves acquiring specific functional capabilities, known as cancer hallmarks.
• These hallmarks are essential for malignancy and are present in cancer cells and the tumor microenvironment (TME).
• The tumor microenvironment comprises various cell types that support tumor growth and progression.

Purpose of the Study:

• To explore the connection between the nervous system and the development of cancer hallmark capabilities.
• To identify neurons and their projections as key components of the TME that induce hallmark functions.
• To investigate aberrant neuronal regulatory circuits in cancer cells that contribute to cancer pathogenesis.

Main Methods:

• This study is a perspective/review, synthesizing existing research.
• It analyzes the role of neuronal components within the tumor microenvironment.
• It examines autocrine and paracrine signaling pathways involving neurons in cancer.

Main Results:

• Neurons and axons are identified as constituents of the TME that induce cancer hallmarks.
• Aberrant neuronal regulatory circuits are implicated in enabling hallmark functions.
• These neuronal influences contribute to the manifestation of cancer pathogenesis.

Conclusions:

• The nervous system is a significant, yet often overlooked, factor in cancer development.
• Neurons and their signaling pathways are critical in establishing and promoting the hallmarks of cancer.
• Targeting neuronal interactions within the TME may offer novel therapeutic strategies for cancer.
