snR30/U17 Small Nucleolar Ribonucleoprotein: A Critical Player during Ribosome Biogenesis

Cells, 2020
The small nucleolar RNA snR30 (U17 in humans) plays a unique role during ribosome synthesis. Unlike most members of the H/ACA class of guide RNAs, the small nucleolar ribonucleoprotein (snoRNP) complex assembled on snR30 does not direct pseudouridylation

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

PROTEOMICS, EarlyView.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

Rpl13a small nucleolar RNAs regulate systemic glucose metabolism [PDF]

Journal of Clinical Investigation, 2016
Small nucleolar RNAs (snoRNAs) are non-coding RNAs that form ribonucleoproteins to guide covalent modifications of ribosomal and small nuclear RNAs in the nucleus. Recent studies have also uncovered additional non-canonical roles for snoRNAs. However, the physiological contributions of these small RNAs are largely unknown.

C/D-Box Snord105b Promotes Tumorigenesis in Gastric Cancer via ALDOA/C-Myc Pathway

Cellular Physiology and Biochemistry, 2018
Background/Aims: Small nucleolar RNAs (snoRNAs) play an important role in carcinogenesis. In this study, we identified a C/D box snoRNA, snord105b, and further investigated the function and mechanism of the snord105b in gastric cancer (GC).

Engineered Ripening-Specific Accumulation of Polyamines Spermidine and Spermine in Tomato Fruit Upregulates Clustered C/D Box snoRNA Gene Transcripts in Concert with Ribosomal RNA Biogenesis in the Red Ripe Fruit

Plants, 2020
Ripening of tomato fruit leads, in general, to a sequential decrease in the endogenous levels of polyamines spermidine (SPD) and spermine (SPM), while the trend for the diamine putrescine (PUT) levels is generally an initial decrease, followed by a ...

Impairing the production of ribosomal RNA activates mammalian target of rapamycin complex 1 signalling and downstream translation factors [PDF]

, 2014
Ribosome biogenesis is a key process for maintaining protein synthetic capacity in dividing or growing cells, and requires coordinated production of ribosomal proteins and ribosomal RNA (rRNA), including the processing of the latter.

Disc‐Toroid Hybrid Lipid Nanoparticles for Efficient Drug Encapsulation and Subcutaneous Delivery

Small, EarlyView.
This study demonstrates sub‐50 nm solid‐lipid nanoparticles with long‐term stability, high drug loading, and strong tissue compatibility. Disc‐toroid morphology is confirmed and may play a role in cellular interactions, while low cytotoxicity and minimal systemic permeation confirm depot‐like behavior. These nanoparticles represent a versatile platform

Molecular Mechanisms and Clinical Implications of Noncoding RNAs in Cancer

Non-Coding RNA
Noncoding RNAs (ncRNAs), which include small nuclear RNAs (snRNAs), small nucleolar RNAs (snoRNAs), microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), are RNA molecules that arise from genomic regions without protein-coding ...

The site of ribonucleic acid synthesis in the isolated nucleus [PDF]

, 1961
There is still controversy concerning the primary site of RNA synthesis in the cell.(1) When tissues are radioautographed after administration of radioactive inorganic phosphorus or radioactive RNA(2) precursors such as tritiated uridine or cytidine, it ...
