Cancer researchers find evolutionary change that occurred in a key developmental signalling pathway

Cancer researchers at the University of Helsinki, in trying to find a novel tumor suppressor gene, instead found an important evolutionary change that occurred in a key developmental signalling pathway. The finding suggests a potential mechanism for evolution of complex intercellular signalling pathways.

HIV subtype is a better predictor than viral load for determining rapid death from AIDS

Traditional testing standards help monitor the progression of an HIV infection to AIDS by keeping track of viral load, using a scale in which less than 50 viral particles per cubic milliliter of blood is considered suppressed disease and a viral load of more than 75,000 particles per cubic milliliter of blood means that the disease will progress more rapidly.

What do mad cow disease and stem cell research have in common? Whitehead Institute scientists have found that the same protein that causes neurodegenerative conditions such as bovine spongiform encephalopathy (mad cow disease) is also important for helping certain adult stem cells maintain themselves.

PET imaging has the potential to improve cancer care management

A limitation of current cancer care is the difficulty of quickly assessing how well a therapy is working. However, expanding the use of existing positron emission tomography (PET) technology can provide early and accurate assessment of a tumor's response to a particular therapy allowing physicians to better tailor a patient's treatment
