Stomach Cancer’s Electrical Connection to Nerves: A Potential Breakthrough
Table of Contents
Researchers at columbia university Vagelos College of Physicians and Surgeons have unveiled a groundbreaking discovery: stomach cancers form electrical connections with nearby sensory nerves, using these malignant circuits to fuel their growth and spread. This marks the first time such electrical contacts between nerves and a cancer outside the brain have been identified, opening exciting new avenues for cancer treatment.
the study, led by Timothy Wang, the Silberberg Professor of Medicine, reveals a previously unknown mechanism by which cancer thrives. We certainly know that many cancers exploit nearby neurons to fuel their growth, but outside of cancers in the brain, these interactions have been attributed to the secretion of growth factors broadly or through indirect effects,
explained Wang, a leader in the emerging field of cancer neuroscience. Now that we know the interaction between the two is more direct and electrical, it raises the possibility of repurposing drugs designed for neurological conditions to treat cancer.
This discovery highlights the speed and efficiency of the nervous system in cancer growth. There are many different cells surrounding cancers, and this microenvironment can sometimes provide a rich soil for their growth,
Wang noted. while research has focused on immune cells, connective tissue, and blood vessels, the role of nerves has only recently come under scrutiny. What’s emerged recently is how favorable the nervous system can be to cancer. The nervous system works faster then any of these other cells in the tumor microenvironment, which allows tumors to more quickly communicate and remodel their surroundings to promote their growth and survival,
he added.
Cancer-Neuron Connections Resemble Synapses
Wang’s research, spanning about 10 years, initially involved cutting the vagus nerve in mice with stomach cancer. This intervention substantially slowed tumor growth and improved survival rates. The study then focused on sensory neurons within the vagus nerve, which reacted most strongly to the presence of stomach cancer. these neurons extended into the tumors in response to Nerve Growth Factor (NGF) released by cancer cells,bringing the cancer cells into close proximity with the neurons. Once connected, the tumors signaled the sensory nerves to release Calcitonin Gene Related Peptide (CGRP), triggering electrical signals within the tumor.
While not classical synapses, the connection undeniably creates an electrical circuit. Though the cancer cells and neurons may not form classical synapses where they meet — the team’s electron micrographs are still a bit fuzzy — “there’s no doubt that the neurons create an electric circuit with the cancer cells,”
Wang stated. It’s a slower response than a typical nerve-muscle synapse,but it’s still an electrical response.
This electrical activity was observed using calcium imaging, a technique that uses fluorescent tracers to illuminate calcium ion surges during electrical impulses.
There’s a circuit that starts from the tumor, goes up toward the brain, and then turns back down toward the tumor again,Wang described.It’s like a feed-forward loop that keeps stimulating the cancer and promoting its growth and spread.
Migraine Drugs: A Potential Cancer Treatment?
The discovery suggests a potential new treatment strategy. CGRP inhibitors,currently used for migraines,could possibly disrupt the electrical connection between tumors and sensory neurons. In Wang’s study, these inhibitors reduced tumor size, extended survival, and prevented metastasis in mice with stomach cancer.
Based on our analysis of stomach cancer data from patients, we believe that the circuits we’ve found in mice also exist in humans and targeting them could be an additional useful therapy,
Wang said.While sensory neurons may also stimulate cancer through indirect pathways, potentially via connective tissue cells or by suppressing immune responses, Wang believes it all starts with the cancer cell setting up a neural circuit.
He further noted that Nerves are an underappreciated master regulator of normal growth and regeneration in animals. We know that when organs form during progress, the nerves lead the way. From that point of view, it was not unexpected that nerves would be driving tumor growth as well.
This research represents an vital advancement in our understanding of cancer and opens up promising new avenues for therapeutic intervention. The potential repurposing of existing migraine drugs for cancer treatment offers a rapid path toward clinical trials and improved patient outcomes.

editor’s Questions and Expert’s Answers
Senior Editor: Could you explain how stomach cancer forms electrical connections with nearby sensory nerves?
Expert: Absolutely. The groundbreaking findings from Columbia University Vagelos College of Physicians and Surgeons have revealed that stomach cancers ingeniously create electrical circuits with sensory nerves.This symbiosis facilitates the cancer’s growth and proliferation, essentially giving it a constant power supply. Normally, such interactions in cancers are thought to occur through chemical signals, but this study uncovered a direct electrical connection. This revelation suggests a novel pathway by which tumors might manipulate the very wiring of our body to accelerate their own growth.
Senior Editor: How do these electrical circuits affect tumor growth and spread?
Expert: The cancer cells essentially hijack the nervous system—a complex and rapid interaction network. The interaction forms a sort of feedback loop where the tumor signals the sensory nerves using a peptide called Calcitonin Gene Related Peptide (CGRP). This interaction doesn’t just enhance growth; it actively promotes the spread of cancer. Researchers likened this to a feed-forward loop,where the cancer uses these neural connections to consistently drive its progression,resembling the way neurons communicate in typical neural circuits.
senior Editor: What makes the nervous system a favorable environment for cancer growth?
Expert: The nervous system operates with exceptional speed compared to other cells often studied in the tumor microenvironment like immune cells or connective tissue. This swiftness in communication provides a privileging condition for the cancer cells, allowing them to swiftly adapt and thrive amidst the antagonistic conditions of a growing tumor. Historically, the focus has been on immune or connective tissue interactions, but the recent turn towards understanding the nervous system’s role illuminates its pivotal position as a master regulator. Nerves, traditionally known for guiding the growth of healthy organs, become a powerful driver of tumor expansion under malignancy.
Senior Editor: Could this discovery influence future treatment strategies?
Expert: Absolutely, the notion of disrupting these circuits is a thrilling therapeutic prospect. Currently,CGRP inhibitors—medications used to treat migraines—are being explored to sever this connection. The initial results in animal models show promise, reducing tumor size and preventing spread. Transferring this strategy to human applications could offer a novel, yet accessible treatment avenue, since CGRP inhibitors are already in widespread clinical use. As this understanding deepens, the possibility of co-opting neurological drugs represents an exciting convergence of cancer treatment and neurology.
Senior Editor: Does this research imply that nerve-focused treatments could become mainstream in cancer therapy?
Expert: While still early days, the prospect is certainly on the horizon. The precedent set by this research highlights how nerve interaction could be a generalized feature in various cancers, not just those of the stomach. By learning more about how nerve circuits contribute to cancer growth, we can potentially design a new class of treatments exploiting this vulnerability.such a shift would echo the historical evolution of medical treatments, much like how immune checkpoint inhibitors transformed cancer therapy by targeting the body’s immune system.
