Turning Cancer’s Achilles’ Heel Into Its Downfall: A Novel Approach

Traditional cancer treatments, like chemotherapy and radiation, often cause collateral damage, harming healthy cells alongside cancerous ones. Now, researchers at Stanford Medicine have developed a groundbreaking approach that harnesses the body’s natural self-destruction mechanisms to target cancer cells specifically.

Flipping the Cancer Script

The key lies in exploiting cancer-driving proteins known as oncogenes. In diffuse large cell B-cell lymphoma, a mutated protein called BCL6 acts as an oncogene, keeping apoptosis-promoting genes switched off. These genes normally trigger programmed cell death, allowing cancer cells to evade destruction.

The Stanford team developed a unique molecule that acts as a molecular glue, attaching BCL6 to CDK9, an enzyme responsible for activating genes. This clever strategy effectively switches on the apoptosis genes that BCL6 normally keeps suppressed.

“The idea is, can you turn a cancer dependency into a cancer-killing signal?” asks Nathanael Gray, PhD, co-senior author of the study and Krishnan-Shah Family Professor of Chemical and Systems Biology. “You take something that the cancer is addicted to for survival and flip the script, making that be the very thing that kills it.”

This innovative approach differs from traditional targeted cancer therapies, which often aim to inhibit oncogenes, switching off their activity. Instead, this method utilizes oncogenes themselves to trigger their own destruction.

“Since oncogenes were discovered, people have been trying to shut them down in cancer,” explains Roman Sarott, PhD, a postdoctoral scholar at Stanford Medicine and co-first author on the study. “Instead, we’re trying to use them to turn signaling on that, we hope, will prove beneficial for treatment.”

This groundbreaking research offers a promising new avenue for cancer treatment, potentially leading to more targeted and effective therapies with fewer side effects. Stay tuned for further developments in this exciting field.
