MYC is a key regulator of RNA Polymerase I (Pol I) transcription, promoting rRNA synthesis both directly and indirectly. MYC overexpression is common in many cancer types, where it drives increased ...
The discovery shows that the production of ribosomal RNA (rRNA) is connected to how cells manage RNA splicing (a process that edits RNA). In studies of cancer cell lines using drugs that block rRNA ...
Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...
In mammalian cells, the nucleolus is the central site for ribosome biogenesis. It is composed of distinct subcompartments: the fibrillar center (FC), the dense fibrillar component (DFC), the periphery ...
