Researchers Discover What Powers Enzyme that Helps Cancer Grow
COPENHAGEN, Denmark, June 29 (UPI) — Researchers have discovered the protein with allows the enzyme ADAM17 removes molecules from the surface of cancer cells, helping them to grow.
The protein PACS-2 helps ADAM17 transport into and out of the cell, however if the protein is blocked the enzyme returns to the cell surface less often, meaning it can’t help cells to grow.
Scientists have long been thwarted at trying to develop drugs that would restrict ADAM17 from removing molecules and helping cancer cells to grow, researchers said.
“There have been attempts at developing a pill to inhibit ADAM17, only the patients became ill due to side effects, because other, similar enzymes were also affected,” said Sarah Dombernowsky, Ph. D. of the University of Copenhagen, in a press release. “But if you inhibit PACS-2, you can, in principle, obstruct only ADAM17, which would enable us to inhibit the growth of the cancer tumour.”
Researchers at the university are currently experimenting with mice to see if cancer growth slows down as a result of blocking PACS-2 with the hope their work will become a usable cancer treatment.
The study is published in Nature Communications.
