Worms in search of tumors: insects under cancer diagnosis


Researchers recently reported that they have successfully trained ants to recognize cancerous cells. Now another group ofAmerican Chemical Society have managed to create a diagnostic system for forms of cancer based on worms, specifically the nematode C. elegans. Using the aforementioned con to support particular chips can actually lead to early diagnosis.

Worms can also diagnose cancer

The words of the researchers behind the study: “Lung cancer cells produce a different set of odor molecules than normal cells. The soil nematode, C. elegans, is known to be attracted to or repelled by certain odors, so we got the idea that the nematode could be used to detect lung cancer. “

Using these worms, whose length is less than a millimeter, they were able in the laboratory to push them towards normal cells. The aforementioned had been positioned inside a structure made of polydimethylsiloxane. At the ends of the two, medium was placed, one normal and one with the aforementioned cells. In reality, not all specimens have moved in the desired direction, but others have not. The difference between the two groups is that the second worms did not have i odr-3 receptors.

At the moment the tests in the laboratory showed an efficacy of 70% in being able to identify the forms of cancer examined, such as lung cancer. Obviously there is a long way to go from here to using worms for diagnosis, but it sets interesting new goals for the future.
