WHERE SCIENCE COMES TO LIFE

The innovative imaging technique that could change the game in our battle against this formidable foe: copper.

A fascinating discovery is set to revolutionize cancer detection and treatment. Professor Sharon Ruthstein from the Department of Chemistry at BIU is pioneering an innovative imaging technique that could change the game in our battle against this formidable foe. Her secret weapon? Copper.

Imagine a world where doctors can peer into the human body and see not just the shape of a tumor, but its very nature – its aggressiveness, its weak points, and its potential resistance to treatment. Hopefully, it will soon be reality. 

Current medical imaging techniques, while invaluable, have their limitations. CT scans and MRIs give us detailed pictures of our body’s structure, while PET scans show us cellular activity. But these methods often fall short when it comes to providing precise information about a tumor’s characteristics and condition. This is where Ruthstein’s research comes in, offering a new lens through which to view cancer.

The revelation here is a radioactive copper-based marker that outshines existing options in several ways. First, it’s exquisitely sensitive to oxygen levels in cells. This might not sound exciting at first, but it’s a game-changer. It allows doctors to identify hypoxic (low-oxygen) areas within tumors – a critical piece of information, as these oxygen-starved regions tend to be more resistant to certain treatments and often indicate a more aggressive cancer.

But that’s not all. Cancer cells, in their relentless drive to grow and spread, have a voracious appetite for copper. Ruthstein’s marker capitalizes on this, accumulating more readily in cancerous cells than in healthy ones, resulting in a stark contrast between normal and cancerous tissues, making tumors stand out.

What sets this marker apart is its dual-action mechanism. It’s not just absorbed more by cancer cells; it also undergoes a chemical transformation based on oxygen levels. This two-pronged approach allows for a more accurate diagnosis of the tumor’s state. Unlike other markers, the copper one provides comprehensive information about the tumor’s microenvironment and clearly defines its boundaries. This wealth of data allows doctors to make more informed decisions about treatment strategies and monitor their effectiveness with unprecedented precision.

But Ruthstein and her team aren’t stopping there. They’re already exploring future applications like using this copper marker in radiotherapy treatments, or combining it with liposomes and nanoparticles to better detect brain cancer. They’re even looking into pairing the marker with antibodies to further enhance its efficiency and accuracy.

The future of cancer detection and treatment is looking brighter than ever, opening a new era in the fight against cancer – one where we can see our enemy more clearly than ever before, and strike with precision and confidence.
