Latest TGF beta Stories
Reproductive and somatic aging use different molecular mechanisms that show little overlap between the types of genes required to keep oocytes healthy and the genes that generally extend life span.
Glioblastoma is regarded as the most malignant form of brain tumor.
Whitehead Institute scientists have determined that master transcription factors determine the genes regulated by key signaling pathways.
Ever since scientists first began growing human cells in lab dishes in 1952, they have focused on improving the chemical soup that feeds the cells and helps regulate their growth.
With stem cells so fickle and indecisive that they make Shakespeare's Hamlet pale by comparison, scientists today described an advance in encouraging stem cells to make decisions about their fate.
Whitehead Institute researchers have identified signals from breast epithelial cells that can induce those cells to transition to and maintain a mesenchymal and stem cell-like cell state that imbues both normal and cancer cells with a greater ability to migrate and self-renew.
Scientists at Johns Hopkins have shown in laboratory experiments in mice that blocking the action of a signaling protein deep inside the heart's muscle cells blunts the most serious ill effects of high blood pressure on the heart.
In an interesting bit of scientific serendipity, researchers at North Carolina State University have found that a chemical compound useful for studying the origins of intestinal birth defects may also inhibit the growth and spread of cancerous tumors.
Resistance to leptin, a protein that plays a key role in regulating metabolism and appetite, may help prevent the development of acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) in individuals with type II diabetes.
