Scientists Find a Weak Spot in Deadly Brain Cancer

Topic: Health

Researchers at The Ohio State University found a protein called SET that can make glioblastoma cells easier to kill with existing therapies. They discovered that blocking SET and related proteins made tumors less likely to form and more vulnerable to radiation.

Glioblastoma is one of the most lethal forms of cancer, and treatment options have not changed much because the tumors often resist both radiation and chemotherapy.

Researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute identified a protein called SET as a possible target to make glioblastoma cells easier to kill with existing therapies. They found that blocking SET and related proteins made tumors less likely to form and more vulnerable to radiation.

The researchers focused on PP2A, an enzyme involved in regulating signals that cancer cells use to grow, survive, and recover from treatment-related damage. Glioblastoma cells appear to interfere with PP2A using three proteins called ANP32A, CIP2A, and SET. When the researchers blocked those proteins in laboratory and animal models, fewer cancer cells survived, and the remaining cells became more vulnerable to radiation.

The study was published in the May 2026 issue of Cancer Letters and was supported by grants from the National Institutes of Health, National Cancer Institute, and The Ohio State University Comprehensive Cancer Center.

Why It Matters

This discovery can lead to new treatments for glioblastoma patients in India, who currently have limited options. It also highlights the importance of basic research in finding solutions to complex health problems.
