The gene Myc is an important factor for the growth of organisms by cell division. It causes the production of a protein which, as a transcription factor, controls the expression of up to 15 % of all human genes. When this gene mutates to an oncogene, the cell proliferates excessively and apoptosis is inhibited. Thereby the gene plays a decisive role in the development of many tumors. The problem is that pharmacological substances do not target Myc as it does not have enzymatic activity of its...

Cancer starts when key cellular signals become abnormal, but U.S. medical scientists say they've discovered cancer can be reversed by lowering such signals. Stanford University School of Medicine researchers say they found lowering levels of one cellular signal under a specific threshold reverses the cancer process in mice, returning tumor cells to their normal, healthy state. The scientists say their finding could help target cancer chemotherapy to tumors, while minimizing side effects for...

Cancer starts when key cellular signals run amok, driving uncontrolled cell growth. But scientists at the Stanford University School of Medicine report that lowering levels of one cancer signal under a specific threshold reverses this process in mice, returning tumor cells to their normal, healthy state. The finding could help target cancer chemotherapy to tumors while minimizing side effects for the body's healthy cells. The researchers identified a precise threshold level of the...
