RNA substances found in cancer communication signal

Researchers from the University of London have found RNA substances in communication signals that are sent around the body by cancer cells, which are essential for the growth of the cells.

The RNA are pieces of genetic code that instruct cells, and ultimately, the body, how to form, acting in a similar way to DNA. The study has also found early indications that these genetic instructions can be intercepted and modified by chemotherapy to help prevent cancer cells growing.

This study adds to a range of evidence investigating a new wave of cancer treatments that stimulate the body’s immune system to fight the disease. The new wave of technology differs from conventional treatments that attack cancer cells directly, although this study highlights the need for more research on the new techniques.

Lead researcher Dr Wai Liu, from St George’s, University of London, says: "Currently, drugs fight cancer either by attacking the tumour cell itself or by disrupting the physical interaction between the tumour and the body, which can dislodge the cell. Only very few target the signals sent between tumour cells and those that make up the micro-environment."
