Biogenesis of ribosomes
WebJan 1, 2024 · The ribosome is the enzymatic macromolecular machine responsible for protein synthesis. The rates of protein synthesis are primarily dependent on translational efficiency and capacity. Ribosome biogenesis has emerged as an important regulator of skeletal muscle growth and maintenance by altering the translational capacity of the cell. WebApr 11, 2024 · Hyperactive ribosome biogenesis is a common feature of a wide variety of human cancers, playing a pivotal role in sustaining the growth and proliferation of cancer cells (Pelletier et al, 2024). Pre-rRNA synthesis is considered to be the rate-limiting step in the process of human ribosome biogenesis ...

WebNational Center for Biotechnology Information WebDec 29, 2024 · Ribosome biogenesis is a complex cellular process that involves synthesis of new ribosomes and requires the coordinated actions of the three types of RNA polymerase (RNA Pol I, II, and III) . RNA Pol I is needed for the transcription of the polycistronic 47S pre-rRNA, which is subsequently processed to yield 18S, 5.8S, and …
WebMar 11, 2024 · Impaired ribosome biogenesis and function is the underlying cause of diseases called ribosomopathies . These disorders are characterized by a wide spectrum of symptoms which, due to a shortage of functional ribosomes, broadly fall under the category of cellular hypo-proliferation phenotypes. For example, bone marrow failure and anemia … WebApr 12, 2024 · Using ribosome purification and Tandem Mass Tag (TMT) proteomics, we found that ribosomes were specifically downregulated during cell cycle arrests in cdc-ts mutants. We saw a similar downregulation of ribosome biogenesis by direct inhibition of TORC1 and in physiological cell cycle arrests induced by pheromone treatment and …
