The influence of 4-thiouridine labeling on pre-mRNA splicing outcomes.

PLoS ONE, 2021
Metabolic labeling is a widely used tool to investigate different aspects of pre-mRNA splicing and RNA turnover. The labeling technology takes advantage of native cellular machineries where a nucleotide analog is readily taken up and incorporated into ...

HIV-1 splicing is controlled by local RNA structure and binding of splicing regulatory proteins at the major 5′ splice site

Journal of General Virology, 2015
The 5' leader region of the human immunodeficiency virus 1 (HIV-1) RNA genome contains the major 5' splice site (ss) that is used in the production of the many spliced viral RNAs. This splice-donor (SD) region can fold into a stable stem-loop structure and the thermodynamic stability of this RNA hairpin influences splicing efficiency.

Splice-site Strength Estimation: A simple yet powerful approach to analyse RNA splicing [PDF]

, 2020
RNA splicing, and variations in this process referred to as alternative splicing, are critical aspects of gene regulation in eukaryotes. From environmental responses in plants to being a primary link between genetic variation and disease in humans, splicing differences confer extensive phenotypic changes across diverse organisms

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Assaying the Effects of Splice Site Variants by Exon Trapping in a Mammalian Cell Line

Bio-Protocol, 2017
There are several in silico programs that endeavor to predict the functional impact of an individual’s sequence variation at splice donor/acceptor sites, but experimental confirmation is problematic without a source of RNA from the individual that ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Global donor and acceptor splicing site kinetics in human cells

eLife, 2019
RNA splicing is an essential part of eukaryotic gene expression. Although the mechanism of splicing has been extensively studied in vitro, in vivo kinetics for the two-step splicing reaction remain poorly understood.

Spatial Organization of Protein-RNA Interactions in the Branch Site-3′ Splice Site Region during pre-mRNA Splicing in Yeast [PDF]

Molecular and Cellular Biology, 2003
A series of efficiently spliced pre-mRNA substrates containing single 4-thiouridine residues were used to monitor RNA-protein interactions involving the branch site-3' splice site-3' exon region during yeast pre-mRNA splicing through cross-linking analysis.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
