Scientists at Johns Hopkins Medicine found a gene called KLF5 that helps pancreatic cancer spread. They used CRISPR technology to discover this.

This master gene, called KLF5, was discovered by scientists at Johns Hopkins Medicine. It seems to play a major role in how pancreatic cancer spreads.

In laboratory-grown cells, the researchers found that KLF5 fuels tumor growth and invasion. This happens not by changing the DNA sequence itself, but by reshaping how DNA is organized and chemically modified.

These epigenetic changes control whether genes are switched on or off. The researchers previously reported in 2017 that the most common form of pancreatic cancer shows widespread epigenetic changes in primary tumors.

The latest findings, published in Molecular Cancer, build on that earlier work and point to new possibilities for treatment.

KLF5 was found to have the strongest effect on promoting the growth and spread of metastatic cancer cells. In samples from patients, 10 out of 13 individuals with pancreatic cancer showed higher levels of KLF5 activity in at least one metastatic tumor compared with their original tumor.

Why It Matters

This discovery can lead to new treatments for pancreatic cancer, which is a major health concern in India. Understanding how cancer spreads can help doctors develop more effective therapies.
