Researchers have found that targeting an enzyme called PGM3 can help stop the growth of glioblastoma, the most dangerous type of brain tumor. Study findings are published online in the journal Science Advances.

This enzyme plays a vital role in the hexosamine synthesis pathway, which is involved in the processes of protein and lipid glycosylation that allow tumors to rapidly grow. Lipid glycosylation is a process where sugar molecules attach to fats (lipids) in the body.

Researchers with The Ohio State University Comprehensive Cancer Center—Arthur G. James and Richard J. Solove Research Institute believe that targeting PGM3 can reduce tumor growth and eliminate glioblastoma cells.

“This research is important because it has found a new target called PGM3...

Fifty years since its discovery, scientists have finally worked out how a molecular machine found in mitochondria allows us to make the fuel we need from sugars, a process vital to all life on Earth.

Scientists at the Medical Research Council (MRC) Mitochondrial Biology Unit, University of Cambridge, have worked out the structure of this machine and shown how it operates like the lock on a canal to transport pyruvate—a molecule generated in the body from the breakdown of sugars—into our mitochondria.

Known as the mitochondrial pyruvate carrier, this molecular machine was first proposed to exist in 1971, but it has taken until now for scientists to visualize its structure at the atomic scale using cryo-electron microscopy, a technique used to ...

Bacteria naturally present in the human intestine (known as the gut microbiota) can transform cholesterol-derived bile acids into powerful metabolites that strengthen anti-cancer immunity by blocking androgen signaling, according to a preclinical study led by Weill Cornell Medicine investigators. The study was published on April 15 in Cell.

“I was very surprised by our findings. As far as I know, no one has previously discovered molecules like these bile acids that can interact with the androgen receptor in this way,” said co-senior author Dr...

Benzodiazepines like Valium and Xanax are often prescribed to treat anxiety, insomnia and seizures. While these drugs can be effective as a short-term treatment, researchers are trying to better understand the impact of benzodiazepines after extended use.

Some experts believe long-term use of the medication may influence inflammation levels in our bodies, as previous research has shown that benzodiazepines may increase the risk of developing or worsening inflammatory conditions, like lung inflammation and inflammatory bowel disease...
