Description
We have investigated the p53-dependent stress response in medium spiny neurons (MSNs) that degenerate in Huntingtons disease. To induce p53 signaling cascade, we have genetically inactivated by the Cre/loxP system the essential RNA polymerase I (Pol I) transcription factor TIF-IA, leading to stabilization of p53 and induction of p53-dependent apoptosis.
