New Rensselaer tools speed stem cell research

Engineers at Rensselaer Polytechnic Institute have developed tools to help solve two of the main problems slowing the progress of stem cell research - how to quickly test stem cell response to different drugs or genes, and how to create a large supply of healthy, viable stem cells to study from only a few available cells.

Customized virus kills brain tumor stem cells that drive lethal cancer

A tailored virus destroys brain tumor stem cells that resist other therapies and cause lethal re-growth of cancer after surgery, a research team led by scientists at the University of Texas M. D. Anderson Cancer Center reports in the Sept. 18 edition of the Journal of the National Cancer Institute.

Genetics of imatinib resistance in acute lymphoblastic leukemia

In the September 15th issue of Genes & Development, Drs. Richard T. Williams, Willem den Besten, and Charles J. Sherr at Howard Hughes Medical Institute, St. Jude Children's Research Hospital in Memphis TN, lend new insights into how an aggressive form of acute lymphoblastic leukemia (ALL) develops, and how sensitivity to the targeted chemotherapeutic drug, imatinib, can be diminished through interactions between tumor cells and the host microenvironment.

Natural protection provides possible new treatments for stroke

Two substances that occur naturally in the brain act to protect the brain during a stroke. This is the conclusion of a dissertation published at the Sahlgrenska Academy, and the discovery may lead to new treatments for stroke patients.
