Tools to watch cells eating could aid diagnoses

Scientists have developed a new imaging technology to visualise what cells eat, which could aid the diagnosis and treatment of diseases such as cancer.

The team has designed chemical probes that light up when they attach to specific molecules that cells eat, such as glucose.

Microscopes

Researchers used microscopes to watch cells eating glucose inside live zebrafish embryos, which are transparent and easy to observe. They found the technique also worked with human cells growing in the lab.

The team says their approach could easily be adapted to look at other molecules that are important for health and disease.

Warning signs

All cells rely on glucose and other molecules for their survival. If a cell’s eating habits change, it can be a warning sign of disease.

Researchers say the new technology could help detect tiny changes in cells’ eating habits inside the body’s tissues, making it easier to spot diseases sooner.

Tracking disease

Doctors could also use the technology to monitor how patients are responding to treatment, by tracking the molecules that are eaten by healthy and diseased cells.

Researchers described the study as an important advance that could improve understanding of the metabolism of diseased cells and one day help develop better therapies.

We have very few methods to measure what cells eat to produce energy, which is what we know as cell metabolism. Our technology allows us to detect multiple metabolites simultaneously and in live cells, by simply using microscopes.

The study, published in the journal Angewandte Chemie, was funded by Medical Research Scotland, the Biotechnology and Biological Sciences Research Council and the European Research Council. The Royal Society and the Wellcome Trust also provided funding.
