Small nuclear RNAs in the ciliateTetrahymena

Nucleic Acids Research, 1985
We have isolated and partially characterized a family of small nuclear RNAs (snRNAs) from three different species of the protozoan Tetrahymena. We find six distinct snRNAs ranging in size from 100 to 250 nucleotides. The two largest snRNAs, as well as an abundant, heterogenous group of smaller snRNAs are found in the nucleolar RNA fraction. None of the

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

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 ...

Plant snRNP Biogenesis: A Perspective from the Nucleolus and Cajal Bodies

Frontiers in Plant Science, 2018
Small nuclear ribonucleoproteins (snRNPs) are protein–RNA complexes composed of specific snRNP-associated proteins along with small nuclear RNAs (snRNAs), which are non-coding RNA molecules abundant in the nucleus.

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

RNA editing of AZIN1 induces the malignant progression of non-small-cell lung cancers

Tumor Biology, 2017
RNA editing is a widespread post-transcriptional mechanism that confers specific and reproducible nucleotide changes in selected RNA transcripts and plays a critical role in many human cancers.

Targeted modulation of IGFL2‐AS1 reveals its translational potential in cervical adenocarcinoma

Molecular Oncology, EarlyView.
Cervical adenocarcinoma patients face worse outcomes than squamous cell carcinoma counterparts despite similar treatment. The identification of IGFL2‐AS1's differential expression provides a molecular basis for distinguishing these histotypes, paving the way for personalized therapies and improved survival in vulnerable populations globally.

A small RNA ofMycoplasma capricolumthat resembles eukaryotic U6 small nuclear RNA

Nucleic Acids Research, 1993
Mycoplasma capricolum, a parasitic prokaryote, contains several small stable RNAs, besides rRNAs and tRNAs. One of them, designated MCS4 RNA (125 nucleotides in length), has been isolated and sequenced. This RNA is abundant in the cell, and is encoded by two genes.

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

Nucleotide sequence of Dictyostelium small nuclear RNA Dd8 not homologous to any other sequenced small nuclear RNA.

Journal of Biological Chemistry, 1983
The cellular slime mold Dictyostelium discoideum, a lower eukaryote, was shown to contain several species of small nuclear RNA (Takeishi, K., and Kaneda, S. (1981) J. Biochem. (Tokyo) 90, 299-308; Wise, J. A., and Weiner, A. M. (1981) J. Biol. Chem. 256, 956-963).
