The nucleolus (/ nj uː ˈ k l iː ə l ə s, ˌ nj uː k l i ˈ oʊ l ə s /; pl.: nucleoli /-l aɪ /) is the largest structure in the nucleus of eukaryotic cells. [1] It is best known as the site of ribosome biogenesis. The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to ...
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. [2] Getti found that in addition to the nucleoplasm, the hnRNPI was staining a “discrete unidentified structure” always opposite of the nucleoli.
Channelopathies are a group of diseases caused by the dysfunction of ion channel subunits or their interacting proteins. These diseases can be inherited or acquired by other disorders, drugs, or toxins. Mutations in genes encoding ion channels, which impair channel function, are the most common cause of channelopathies. [1]
In fact, DNA analysis of these two types of domains have shown that many sequences overlap, indicating that certain regions may switch between lamina-binding and nucleolus-binding. [35] NADs are associated with nucleolus function. The nucleolus is the largest sub-organelle within the nucleus and is the principal site for rRNA transcription.
Polyomaviridae is a family of DNA viruses whose natural hosts are mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.
Cytopathic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. [1] If a virus causes these morphological changes in the host cell, it is said to be cytopathogenic. [2]
One hypothesized function of the dots is as a 'nuclear dump' or 'storage depot'. [21] The nuclear bodies may not all perform the same function. Sp140 associates with certain bodies and appears to be involved in transcriptional activation. [22] ND10 nuclear bodies have been shown to play a major role in chromatin regulation. [23]
