Sno Storm in the Nucleolus: New Roles for Myriad Small RNPs
these snoRNAs. Yet, as more snoRNAs were discovBiologists have known for decades that the nucleolus ered, not all exhibited the hallmarks of U3, U8, and U13: is the compartment of the eukaryotic cell most densely some possessed an unmodified terminal 59 monophospacked with RNA. But few would have guessed that, in phate instead of the TMG cap and some lacked the addition to the ribosomal RNAs (r...
متن کاملA SNO Storm in Skeletal Muscle
Dysregulated S-nitrosylation of proteins characterizes a broad array of human disorders, but its role in disease etiology is not well understood. Two new studies (Durham et al., 2008; Bellinger et al., 2008) now show that hyper-S-nitrosylation of the ryanodine receptor calcium release channel (RyR1) in skeletal muscle disrupts calcium ion flux. This disruption underlies the impaired contractili...
متن کاملBiogenesis of small nuclear RNPs.
The nucleus contains a large number of metabolically stable, 60-450-nt-long small nuclear RNAs (snRNAs) that exist in the form of ribonucleoproteins (snRNPs) (Yu et al., 1999). Each snRNP is composed of an snRNA and a set of associated RNP proteins. Based on their function and intranuclear localization, mammalian snRNPs can be classified into three major classes. The U1, U2, U4, U5 and U6 major...
متن کاملthe search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولNew roles for Dicer in the nucleolus and its relevance to cancer
The nucleolus is a distinct compartment of the nucleus responsible for ribosome biogenesis. Mis-regulation of nucleolar functions and of the cellular translation machinery has been associated with disease, in particular with many types of cancer. Indeed, many tumor suppressors (p53, Rb, PTEN, PICT1, BRCA1) and proto-oncogenes (MYC, NPM) play a direct role in the nucleolus, and interact with the...
