regulator called NF Kappa B (pronounced "en-ef-kappa-bee"). The NF Kappa B protein is well known to researchers as a transcription factor that regulates many genes. In cancer cells, NF Kappa B regulates genes involved in cancer cell survival, prolif...
Neuronal death and processing of Tau protein in Alzheimer's disease
...omosome 17 (FTDP-17), several mutations in the tau gene
were identified showing that primary malfunction of tau can lead to neurodegeneration. Such findings shed new light on the role of post-translational modifications of tau protein occurring in other tauopathies (such as AD), including aberrant proteol...
