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 ...

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 ...

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 ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 119, No. 50 (December 13, 2022), pp. 1-12 (12 pages) R-loops, or RNA:DNA hybrids, can induce DNA damage, which ...

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 ...

Researchers at the Johns Hopkins Kimmel Cancer Center and Department of Radiation Oncology and Molecular Radiation Sciences uncovered a new tumor-suppressive response that could lead to novel ...
