Research isn’t always about discovering a new drug or finding a new treatment target. Sometimes, an equally important step is understanding what is happening inside cells. 🧫🔬
The aim of this study, led by Dr Daniel Coleman (one of our previous John Goldman Fellows), was to develop a way of measuring MAPK activity: an important signalling pathway that helps cells grow, survive and respond to their environment.
Dr Coleman and colleagues developed modified viruses, called lentiviral vectors, that carry a gene producing a light-emitting protein called luciferase. In simple terms, the more light the cells produce, the more active the MAPK pathway is.
They tested different versions of these tools in leukaemia cells.
One version, LEGO-AP1x6-GM55, was able to produce a strong signal when MAPK was switched on. Importantly, drugs that block MAPK signalling reduced the signal, showing that the system was accurately detecting MAPK activity.
🔸 Why this matters:
Having a way to see and measure MAPK activity in living cells in almost real time gives researchers a powerful tool for understanding how cells behave in health and disease.
In the long term, this could help us better understand how cancer cells use signalling pathways to grow and survive, how different mutations affect these pathways, and how cells respond to drugs that target them.
