WebbThe perinucleolar compartment (PNC) is a subnuclear body that forms in cancer cells. In vivo analyses using human tumor tissues demonstrate a close correlation between PNC … 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 csgo ak jet set sticker combos
