CUMC researchers clarify three fundamental problems about Alzheimer’s disease Amyloid accelerates tau toxicity Using high-resolution practical MRI imaging in patients with Alzheimer's disease and in mouse models of the condition, Columbia University Medical Center experts have clarified three fundamental issues regarding Alzheimer's: where it starts, so why it starts there, and how it spreads. In addition to advancing knowledge of Alzheimer's, the findings could improve early recognition of the disease, when drugs may be most effective. Today in the online edition of the journal Nature Neuroscience The study was published Kostnaden för cialis .

Just as important, the findings provide a mechanistic insight into how a new course of promising drugs – one version of which has already been in human scientific trials – seems to halt the growth of cancer cells so effectively. The research, appearing today in Genes & Development and led by CSHL Associate Professor Chris Vakoc, centers on just how a cancer-promoting gene is certainly controlled. When this oncogene, known as Myc, is robustly expressed, it instructs cells to produce proteins that contribute to the uncontrolled development that is malignancy's hallmark. The Myc oncogene is normally implicated in many other tumor types also, adding to the significance of the new finding. Vakoc's group discovered an enhancer component that settings the Myc oncogene specifically in leukemia cells.
