Dr Julie Sharp, senior science information manager at Cancer Research UK, said:
Finding ways to disrupt the tools that cancer cells use to adapt and grow when starved of oxygen has been a hot topic in cancer research, but finding drugs that do this effectively has proved elusive.
For the first time our scientists have found a way to block a master switch controlling cells response to low levels of oxygen - an important step towards creating drugs that could halt cancer in its tracks.
