Studies on the interactions of low molecular weight ribosomal RNAs and ribosomal proteins [PDF]

, 1984
For an understanding of the molecular events that occur on the ribosome during protein biosynthesis, the interaction of proteins and RNA within the ribosome must be understood.

Nanoparticle‐Mediated CXCL12–CXCR4 Inhibition Reprograms Macrophages and Suppresses Gastric Carcinoma

Advanced Science, EarlyView.
Molecular mechanism study of self‐assembled M2pep‐Cs NPs/Plerixafor nanoparticles in targeting MΦ reprogramming by regulating the CXCL12–CXCR4 signaling pathway to enhance immune recognition and clearance of GC (Created by BioRender). Abstract Gastric carcinoma (GC) remains a major global health challenge, requiring novel therapeutic approaches.

Overexpression of a Brix Domain-Containing Ribosome Biogenesis Factor ARPF2 and its Interactor ARRS1 Causes Morphological Changes and Lifespan Extension in Arabidopsis thaliana

Frontiers in Plant Science, 2018
The Brix domain is a conserved domain in several proteins involved in ribosome biogenesis in yeast and animals. In the Arabidopsis genome, six Brix domain-containing proteins are encoded; however, their molecular functions have not been fully ...

Temporal order of replication of Xenopus laevis 5S ribosomal RNA genes in somatic cells.

Proceedings of the National Academy of Sciences of the United States of America, 1986
The timing of replication of both the somatic and oocyte-type 5S ribosomal RNA genes of Xenopus laevis was determined in cultured cells by using 5-bromodeoxyuridine labeling of DNA coupled with a retroactive synchrony technique employing the fluorescence-

Broad role for YBX1 in defining the small noncoding RNA composition of exosomes. [PDF]

, 2017
RNA is secreted from cells enclosed within extracellular vesicles (EVs). Defining the RNA composition of EVs is challenging due to their coisolation with contaminants, lack of knowledge of the mechanisms of RNA sorting into EVs, and limitations of ...

STK25 Loss Augments Anti‐PD‐1 Therapy Efficacy by Regulating PD‐L1 Stability in Colorectal Cancer

Advanced Science, EarlyView.
This study demonstrates that STK25 depletion facilitates CRC immune escape through the inhibition of PD‐L1 Ser283 phosphorylation‐mediated ubiquitination, and promotes tumor growth. Furthermore, these findings identify STK25 as a potential therapeutic target to trigger antitumor immunity and promote immunotherapy efficacy. Abstract Tumor immune evasion

DNA-methylation dependent regulation of embryo-specific 5S ribosomal DNA cluster transcription in adult tissues of sea urchin Paracentrotus lividus [PDF]

, 2013
We have previously reported a molecular and cytogenetic characterization of three different 5S rDNA clusters in the sea urchin Paracentrotus lividus and recently, demonstrated the presence of high heterogeneity in functional 5S rRNA.

LncRNA TMEM99 Complexes with IGF2BP2 to Inhibit Autophagy in Lung Adenocarcinoma

Advanced Science, EarlyView.
LncRNA TMEM99 is significantly upregulated in lung adenocarcinoma (LUAD) and correlates with poor prognosis. It promotes LUAD cell proliferation, migration, and invasion while suppressing autophagy. Mechanistically, TMEM99 binds FUBP3 and recruits IGF2BP2 in an m⁶A‐dependent manner to stabilize and enhance p21 mRNA translation, uncovering a novel ...

Oocyte and somatic 5S ribosomal RNA and 5S RNA encoding genes in Xenopus tropicalis

Nucleic Acids Research, 1988
We have investigated the structure of oocyte and somatic 5S ribosomal RNA and of 5S RNA encoding genes in Xenopus tropicalis. The sequences of the two 5S RNA families differ in four positions, but only one of these substitutions, a C to U transition in position 79 within the internal control region of the corresponding 5S RNA encoding genes, is a ...

SNORA58 Facilitates Radioresistance via Suppressing JNK1‐Mediated Ferroptosis in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
In ESCC patients, SNORA58 exhibits heterogeneous expression patterns. Its aberrant overexpression stabilizes CTCF by inhibiting ubiquitin‐mediated degradation, leading to the attenuation of JNK1‐mediated ferroptosis induced by radiotherapy through disruption of intracellular iron homeostasis, and ultimately contributes to radioresistance ...
