In plain words
Why a drug can stop working.
Some cancer drugs target one signal that a tumour depends on. They can work well for a time. But a tumour is made of many cells, and a few of them can find another way to survive. When those cells grow back, the drug may no longer work as well. Doctors call this drug resistance.
The story in three frames
How resistance happens.
1. The drug works
Most of the tumour’s cells depend on the signal the drug blocks, so the tumour shrinks.
2. A few cells adapt
Some cells survive. They may change the drug’s target, switch to another growth signal, or change type.
3. The tumour returns, changed
The survivors grow back. The tumour now responds differently, and the same drug no longer works as well.
The drawings are simplified. Real tumours are more varied, and the same drug can fail in different ways in different people.
Donated samples
Making each donated sample count.
Researchers can grow small living models of a tumour from donated tissue and test drugs on them in the lab. There are never enough of these samples. Cytogent helps researchers choose the experiments that will teach the most, so that each donation is used well.
