Evidence for a nuclear compartment of transcription and splicing located at chromosome domain boundaries [PDF]

open access: yes, 1993
The nuclear topography of splicing snRNPs, mRNA transcripts and chromosome domains in various mammalian cell types are described. The visualization of splicing snRNPs, defined by the Sm antigen, and coiled bodies, revealed distinctly different ...

Nuclear Retention Elements of U3 Small Nucleolar RNA [PDF]

open access: yesMolecular and Cellular Biology, 1999
The processing and methylation of precursor rRNA is mediated by the box C/D small nucleolar RNAs (snoRNAs). These snoRNAs differ from most cellular RNAs in that they are not exported to the cytoplasm. Instead, these RNAs are actively retained in the nucleus where they assemble with proteins into mature small nucleolar ribonucleoprotein particles and ...

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

open access: yesMolecular 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 ...

Localisation of the Ki-67 antigen within the nucleolus: Evidence for a fibrillarin-deficient region of the dense fibrillar component [PDF]

open access: yes, 1996
The Ki-67 antigen is detected in proliferating cells in all phases of the cell division cycle. Throughout most of interphase, the Ki-67 antigen is localised within the nucleolus.

MINTmap: fast and exhaustive profiling of nuclear and mitochondrial tRNA fragments from short RNA-seq data. [PDF]

open access: yes, 2017
Transfer RNA fragments (tRFs) are an established class of constitutive regulatory molecules that arise from precursor and mature tRNAs. RNA deep sequencing (RNA-seq) has greatly facilitated the study of tRFs.

Evolutionary origin of the U6 small nuclear RNA intron. [PDF]

open access: yesMolecular and Cellular Biology, 1990
U6 is the most conserved of the five small nuclear RNAs known to participate in pre-mRNA splicing. In the fission yeast Schizosaccharomyces pombe, the single-copy gene encoding this RNA is itself interrupted by an intron (T. Tani and Y. Ohshima, Nature (London) 337:87-90, 1989).

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

open access: yesMolecular 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 ...

Long noncoding RNAs in prostate cancer: overview and clinical implications. [PDF]

open access: yes, 2016
Prostate cancer is the second most common cause of cancer mortality among men in the United States. While many prostate cancers are indolent, an important subset of patients experiences disease recurrence after conventional therapy and progresses to ...

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

open access: yesMolecular 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.

Taxonomy and Phylogeny of Polyporus Group Melanopus (Polyporales, Basidiomycota) from China.

open access: yesPLoS ONE, 2016
Melanopus is a morphological group of Polyporus which contains species with a black cuticle on the stipe. In this article, taxonomic and phylogenetic studies on Melanopus group were carried out on the basis of morphological characters and phylogenetic ...
