Non‐Coding Transcripts From Diversified Members of IgLec Family Protect Antiviral Effectors From Viral miRNA

Advanced Science, EarlyView.
The IgLec gene family generates both protein‐coding antiviral effectors and non‐coding transcripts. Upon viral infection, non‐coding transcripts are preferentially targeted by viral miR‐N48, thereby buffering protein‐coding isoforms from repression. Depletion of these decoy transcripts compromises antiviral defense, revealing a non‐coding RNA‐mediated ...

DUET‐seq: An Open‐Source Droplet Platform for High‐Fidelity Joint Chromatin and Transcriptome Profiling Reveals Temporal Regulatory Decoupling in Single Cells

Advanced Science, EarlyView.
DUET‐seq is an open‐source droplet platform that jointly profiles chromatin accessibility and gene expression from the same nucleus. Dissolvable dual‐linker hydrogel beads and a one‐step intra‐droplet RT‐PCR co‐index both modalities in under 12 h at roughly $0.04 per cell.

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

Advanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

Splicing factors: Insights into their regulatory network in alternative splicing in cancer

Cancer Letters, 2021
More than 95% of all human genes are alternatively spliced after transcription, which enriches the diversity of proteins and regulates transcript and/or protein levels. The splicing isoforms produced from the same gene can manifest distinctly, even exerting opposite effects.

Splice Factor

Science Signaling, 2008
Alternative splicing of transcripts generates significant functional diversity within genomes. This is particularly well illustrated by the CD45 gene, which undergoes regulated activation-dependent alternative splicing in lymphocytes to generate several functionally distinct isoforms.

Modelling the compartmentalization of splicing factors

Journal of Theoretical Biology, 2006
Splicing factor (SF) compartments, also known as speckles, are heterogeneously distributed compartments within the nucleus of eukaryotic cells that are enriched in pre-mRNA SFs. We derive a fourth-order aggregation-diffusion model that describes a possible mechanism underlying the organization of SFs into speckles. The model incorporates two hypotheses,

The Arabidopsis splicing factor SR1 is regulated by alternative splicing

Plant Molecular Biology, 2000
The serine-arginine (SR)-rich splicing factors play essential roles in general splicing and regulate alternative splice site utilization in a concentration-dependent manner. SR1 is a plant homologue of the human general/alternative splicing factor SF2/ASF. We report here that alternative splicing regulates SR1 itself.

A PROTAC targets splicing factor 3B1

Cell Chemical Biology, 2021
The proteolysis-targeting chimeras (PROTACs) are a new technology to degrade target proteins. However, their clinical application is limited currently by lack of chemical binders to target proteins. For instance, it is still unknown whether splicing factor 3B subunit 1 (SF3B1) is targetable by PROTACs.

Regulation of Alternative Splicing in Vivo by Overexpression of Antagonistic Splicing Factors

Science, 1994
The opposing effects of SF2/ASF and heterogeneous nuclear ribonucleoprotein (hnRNP) A1 influence alternative splicing in vitro. SF2/ASF or hnRNP A1 complementary DNAs were transiently overexpressed in HeLa cells, and the effect on alternative splicing of several cotransfected reporter genes was measured.

Splice factor mutations and alternative splicing as drivers of hematopoietic malignancy

Immunological Reviews, 2014
SummaryDifferential splicing contributes to the vast complexity of mRNA transcripts and protein isoforms that are necessary for cellular homeostasis and response to developmental cues and external signals. The hematopoietic system provides an exquisite example of this.
