Dr Strasser said this finding suggests that strategies for treating tumours by attacking the tumour blood supply could be optimised by incorporating drugs called BH3-mimetics that cause cell death by acting like Bim at a molecular level. "Similarly, therapies that increase the amount of Bim in tumour blood vessels could enhance the effects of anti-angiogenic agents," Dr Strasser said.

"BH3 mimetics may have two beneficial effects in cancer therapy. Our previous research had showed they can directly trigger death in tumour cells, particularly when the tumour is also attacked by chemotherapeutic drugs. We now think BH3-mimetics could also impact tumour cells indirectly by killing endothelial cells within tumours.

"This suggests that a promising new approach to the therapy of solid tumours may be to use a three-medication combination of a drug that specifically targets the tumour cell, an anti- angiogenic agent to impair the tumour blood vessels, plus a BH3 mimetic that will help the anti- tumour drug to directly kill the tumour cells and also will help the anti-angiogenic agent to kill the intra-tumoral endothelial cells, which in turn will starve the tumour, causing even more tumour cell death."
