Analyzing the RNA expression patterns of cancer cells can reveal their susceptibility to different drugs, according to new work from Shalek and Manalis lab researchers and their Bridge Project collaborators. In a study of pancreatic cancer cells, published in Cell, the team also demonstrated that changes to the tumor microenvironment can drive cells from one RNA-expression state to another. Their findings suggest that it may be possible to treat some patients’ tumors more effectively by first modifying signals in the tumor microenvironment to lock it in a particular state, and then giving a drug that targets that state.
The work was funded in part by the Bridge Project and the Ludwig Center for Molecular Oncology at MIT.
