Webb15 aug. 2001 · The perinucleolar compartment (PNC) and the SAM68 nuclear body (Huang, 2000EF5) have been identified as unique structures that are associated with the surface of nucleoli and are thought to play a role in RNA metabolism. They range in size from 0.25-1.0 μm in diameter, and 1-10 are observed per nucleus. WebbThe perinucleolar compartment (PNC) is a dynamic, irregularly shaped, and electron-dense nuclear structure that is physically associated with the nucleolus (1).

WebbAs a driven pharmacy student, I am privileged to work in Kevin Frankowski's lab, where I'm immersed in the exciting world of designing … The perinucleolar compartment (PNC) is a subnuclear body characterized by its location at the periphery of the nucleolus. The PNC participates in the patterned compartmentalization inside the nucleus to organize the specialized functions. It is almost exclusively found in oncogenic cells and enriched with … Visa mer The perinucleolar compartment was first discovered on the periphery of the nucleus in 1992 by Andrea Getti et al. while studying the hnRNPI/PTB (polypyrimidine tract binding) protein. Getti found that in addition to the … Visa mer Although the precise function has not been established, the perinucleolar compartment is concentrated with RNA binding proteins as well as newly transcribed RNA … Visa mer The PNC is a dynamic and irregular structure composed of multiple dense strands found primarily in transformed cancer cells. Electron microscopy on HeLa cells confirmed that the thick strands are 0.25 - 4 µm in length and 80 - 180 nm in diameter. These … Visa mer Perinuclolar compartments form in blastomas, carcinomas, and sarcomas and exclusively represent malignant cells in solid tumor tissues. The occurrence of the PNC directly correlates with the growth and metastasis of cancer cells. For example, in a study on Visa mer Webb15 mars 2005 · The perinucleolar compartment (PNC) is a sub‐nuclear structure that preferentially localizes to the nucleolar periphery. The PNC is found predominantly in transformed cells both in vitro and in vivo.
