Human cells with a 'built-in circuit' help prevent tumour growth
Researchers at the University of Southampton have engineered cells with a 'built-in genetic circuit' that produces a molecule that inhibits the ability of tumours to survive and grow in their low oxygen environment. The genetic circuit produces the machinery necessary for the production of a compound that inhibits a protein which has a significant and critical role in the growth and survival of cancer cells. This results in the cancer cells being unable to survive in the low oxygen, low nutrient tumour micro-environment. As tumours develop and grow, they rapidly outstrip the supply of oxygen delivered by existing blood vessels. This results in cancer cells needing to adapt to low oxygen environment.

Cancer gene mutations can predict response to less intensive treatment in AML patients
Patients with the most lethal form of acute myeloid leukemia (AML) - based on genetic profiles of their cancers - typically survive for only four to six months after diagnosis, even with aggressive chemotherapy. But new research indicates that such patients, paradoxically, may live longer if they receive a milder chemotherapy drug. Treatment with the less intensive drug, decitabine, is not a cure. But surprisingly, AML patients whose leukemia cells carried mutations in a nefarious cancer gene called TP53 consistently achieved remission after treatment with decitabine. Their median survival was just over a year. The study, by a team of scientists at Washington University School of Medicine in
