Reducing vitamin B5 slows breast cancer growth in mice

A group of researchers led by the Francis Crick Institute, working with the National Physical Laboratory (NPL) and Imperial College London, have discovered that breast cancer cells expressing a cancer-driving gene heavily rely on vitamin B5 to grow and survive. The researchers are part of Cancer Grand Challenges team Rosetta, funded by Cancer Research UK.

In their research published today in Nature Metabolism, the team studied the metabolic effects of one of the major cancer-driving genes called Myc. In tumour cells where Myc is highly expressed, it disturbs normal processes, drives cell growth and also makes tumour cells dependent on certain nutrients.

These dependencies could be exploited as potential therapeutic targets, but it’s hard to appropriately identify and target metabolic dependencies in human tumours, as Myc expression can vary throughout the tumour.

The researchers…
