Cancer Cells Secret Weapon - Glutamine
🧬 Can a single amino acid shape how cancer cells survive stress?
Surprisingly- yes. And that amino acid is glutamine.
In a remarkable new collaborative study, Prof. Yaron Shav-Tal, Dr. Dana Ishay-Ronen (Sheba Medical Center, Tel Hashomer), and their team demonstrate that glutamine isn’t just fuel- it’s a critical trigger for survival.
When cancer cells are starved of nutrients and face oxidative stress, their ability to form stress granules- tiny, temporary shelters for RNA- is lost. But when glutamine is reintroduced, this protective mechanism springs back into action, restoring energy levels and boosting cell survival.
What’s striking is how specifically this response is wired. It relies on the metabolic regulator MYC and the RNA-binding proteins G3BP1/2, which together enable cells to reorganize under pressure.
🌍 Why this matters:
This discovery sharpens our understanding of how tumors endure hostile conditions, and it opens the door to new strategies that could interrupt that resilience. By targeting glutamine pathways, we may be able to make cancer cells more vulnerable at their most fragile point.
Huge respect to Prof. Yaron Shav-Tal and his team for revealing such a crucial link between metabolism, stress response, and survival.
