Cancer breakthrough as scientists find way to block deadly disease

Scientists have found a new way to tackle the deadliest cancer by blocking its energy supply. The Institute of Cancer Research in London discovered that pancreatic tumors can “switch their diet” to feed off a chemical if they run low on sugar.

Researchers suggest that developing drugs to starve them of the vital fuel source – uridine – could improve treatment and boost survival rates. Pancreatic cancer has the highest death rate in England, killing nine in 10 patients within five years.

According to the scientists, experiments on mice found that switching off a gene named UPP1 could prevent pancreatic tumors from turning uridine into energy.

The institute found that it “largely halted tumor growth” in the animals and hopes the same tactic will work in humans.

Professor Kristian Helin, chief of the Institute for Cancer Research, said: “People with pancreatic cancer often face a bleak prognosis so there is an urgent need for new advances to help treat this aggressive disease.

“It is exciting that this new study has found that pancreatic cancers can switch their diets and may become dependent on a particular backup fuel.

“We hope we can take advantage of this to find ways to treat the disease more effectively.” Uridine is naturally created in the body and its function is to carry genetic information and maintain a healthy metabolism and brain function.

Scientists have previously found that cancer patients had worse survival if they had large amounts of the UPP1 enzyme that breaks uridine down into sugar.

Study co-leader Dr. Costas Lyssiotis, from the University of Michigan, added: “These very exciting findings open up new avenues for treating cancer that currently lacks effective treatment options.

“We can target the fact that pancreatic cancer cells can become dependent on uridine for their growth and survival.” Dr. Chris Macdonald, head of research at Pancreatic Cancer UK, said: “This work is hugely novel, potentially very impactful, and genuinely exciting.

“We are very hopeful that these findings could lead to new and improved treatments for pancreatic cancer in the future.”
