Texas A&M Researchers Uncover New Method to Stop Aggressive Childhood Cancer
Researchers at Texas A&M University Health Science Center have made a groundbreaking discovery in the fight against one of the most aggressive forms of kidney cancer affecting children and young adults. Their findings, published in Nature Communications, reveal a novel approach to halting tumor growth at its source.
Unveiling the Cancer’s Hidden Mechanism
The study focuses on translocation renal cell carcinoma (tRCC), a rare kidney cancer driven by TFE3 oncofusions—hybrid genes formed due to faulty chromosome fusion. The researchers discovered that RNA, typically a messenger molecule, is manipulated by cancer cells to create liquid-like “droplet hubs” within the cell nucleus. These hubs serve as command centers that activate genes promoting tumor growth.
A Molecular Solution to Stop Tumor Growth
Using advanced tools like CRISPR gene editing and next-generation sequencing, the team identified how TFE3 oncofusions and RNA collaborate to form these hubs. They also pinpointed an RNA-binding protein, PSPC1, which stabilizes these droplets, fueling cancer progression. To counter this, the researchers developed a nanobody-based chemogenetic tool—a molecular “off switch” that dissolves the droplets when activated, effectively stopping tumor growth in lab and animal models.
Hope for New Therapies
“This discovery provides a new way to target a cancer with limited treatment options,” said Dr. Yubin Zhou, Director of the Center for Translational Cancer Research. “By disrupting these droplet hubs, we can develop more precise and less toxic therapies.” Dr. Yun Huang, Professor at the Texas A&M Health Institute of Biosciences and Technology, added, “RNA is not just a messenger; it actively builds these condensates, making it a key player in cancer growth.”
Broader Implications for Childhood Cancers
The approach could extend beyond tRCC, as many childhood cancers are driven by similar fusion proteins. “By understanding how these proteins interact with RNA, we’re identifying vulnerabilities that can be targeted for therapy,” said Dr. Lei Guo, Research Assistant Professor at the Institute of Biosciences and Technology. With tRCC accounting for about 30% of renal cancers in children and adolescents, this breakthrough offers renewed hope for patients and families facing this challenging disease.
