Researchers Use Tumor Gas To Produce Anticancer Compounds

Buzzline

Researchers at Japan's RIKEN Pioneering Research Institute have developed an experimental approach that uses carbon monoxide produced by cancer cells to make an anticancer compound inside them, according to a study in Nature Communications. A palladacycle catalyst shielded inside the blood protein albumin produced the toxic compound in human liver, cervical, breast, and lung cancer cells after 48 hours, but not in noncancerous cells or in blood. The work remains at an early laboratory stage and aims to reduce chemotherapy side effects.  Disclosure: This video contains stock footage and content created or enhanced using AI-assisted tools.

00:00Researchers have found a way to make cancer cells build the drug that attacks them.

00:04The team at RIKEN in Japan targets carbon monoxide.

00:07Many cancer cells naturally produce unusually high amounts of that gas.

00:12The researchers used a metal compound called a pallidocycle.

00:15It reacts with carbon monoxide to create a molecule toxic to cells.

00:19To protect it inside the body, they wrapped it in albumin, a common blood protein.

00:24They tested liver, cervical, breast, and lung cancer cells for 48 hours.

00:29The drug formed inside the cancer cells, but not in normal cells.

00:33In liver cancer cells, it caused signs of damage.

00:36It also didn't form in blood, where carbon monoxide is bound to hemoglobin.

00:41The work appears in Nature Communications.

00:43It's still early-stage lab research.

00:46The goal is fewer side effects than standard chemotherapy.
