RegulationoftranscriptionalactivitybyPML
The PML nuclear bodies are ring-shaped nuclear substructures associated with the regulation of transcription, transformation, cell growth, and apoptosis and are characterized by the presence of the protein PML. The activities of PML as a tumor suppressor and apoptosis inducing factor are exerted through the numerous proteins it interacts with in the PML-nuclear bodies including the tumor suppressor p53. DNA damage in......阅读全文
