Fat fuels cancer’s spread in mice

Monday, December 12th, 2016

The cells responsible for cancer’s spread — and for most deaths from cancer — may have a fatal weakness according to studies in mice: a reliance on certain fats to fuel their invasion.

Gene signature in healthy brains pinpoints the origins of Alzheimer’s disease

A specific gene expression pattern maps out which parts of the brain are most vulnerable to Alzheimer’s disease, decades before symptoms appear, and helps define the molecular origins of the disease.

How cancer cells fuel their growth

Wednesday, March 16th, 2016

Scientists surprised to find amino acids, not sugar, supply most building blocks for tumor cells.

Scientists had believed that most of the cell mass that makes up new cells, including cancer cells, comes from that glucose. However, MIT biologists have now found, to their surprise, that the largest source for new cell material is amino acids, which cells consume in much smaller quantities.
