Scientists identify new fuel-delivery route for cells

Scientists at Washington University School of Medicine in St. Louis have identified a previously unknown route for cellular fuel delivery, a finding that could shed light on the process of aging and the chronic diseases that often accompany it. With age, cells gradually lose their ability to take in and process fuel. A cell that can't fill its fuel tank, so to speak, can't perform its proper functions. Researchers are

Next step towards replacement therapy in type 1 diabetes

Scientists have discovered the signals that determine the fate of immature cells in the pancreas. The research shows that they are very mobile and that their destiny is strongly influenced by their immediate environment. This breakthrough published in the journal Nature will facilitate the manufacturing of pancreatic islet cells from stem cells and might help combating type 1 diabetes.

Scientists Find Possible Achilles Heel of Treatment Resistant Cancers

Scientists identify two signaling proteins in cancer cells that make them resistant to chemotherapy, and show that blocking the proteins along with chemotherapy eliminate human leukemia in mouse models. Reporting results March 20 in Nature Medicine, researchers at Cincinnati Children’s Hospital Medical Center suggest that blocking the signaling proteins c-Fos and Dusp1 as part of combination therapy might cure several types of kinase-driven, treatment-resistant leukemia and solid tumor cancers. These

St. Jude Researchers Reveal How Two Types of Immune Cells Can Arise From One

The fates of immune cells can be decided at the initial division of a cell. Researchers at St. Jude Children’s Research Hospital have discovered that the production of daughter cells with different roles in the immune system is driven by the lopsided distribution of the signaling protein c-Myc. Nudging c-Myc in one direction or the other could make vaccines more effective or advance immunotherapies for cancer treatment. The research appears
