Structural basis for specific RNA recognition by the alternative splicing factor RBM5

Nature Communications, 2022
Abstract The RNA-binding motif protein RBM5 belongs to a family of multi-domain RNA binding proteins that regulate alternative splicing of genes important for apoptosis and cell proliferation and have been implicated in cancer.

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.

Emerging roles of alternative RNA splicing in oral squamous cell carcinoma

Frontiers in Oncology, 2022
Alternative RNA splicing (ARS) is an essential and tightly regulated cellular process of post-transcriptional regulation of pre-mRNA. It produces multiple isoforms and may encode proteins with different or even opposite functions. The dysregulated ARS of

RNA Induces Conformational Changes in the SF1/U2AF65 Splicing Factor Complex [PDF]

Journal of Molecular Biology, 2011
Spliceosomes assemble on pre-mRNA splice sites through a series of dynamic ribonucleoprotein complexes, yet the nature of the conformational changes remains unclear. Splicing factor 1 (SF1) and U2 auxiliary factor (U2AF(65)) cooperatively recognize the 3' splice site during the initial stages of pre-mRNA splicing.

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

Molecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Therapeutic potential of alternative splicing in cardiovascular diseases

EBioMedicine
Summary: RNA splicing is an important RNA processing step required by multiexon protein-coding mRNAs and some noncoding RNAs. Precise RNA splicing is required for maintaining gene and cell function; however, mis-spliced RNA transcripts can lead to loss ...

RNA splicing factor RBFOX2 is a key factor in the progression of cancer and cardiomyopathy

Clinical and Translational Medicine
AbstractBackgroundAlternative splicing of pre‐mRNA is a fundamental regulatory process in multicellular eukaryotes, significantly contributing to the diversification of the human proteome. RNA‐binding fox‐1 homologue 2 (RBFOX2), a member of the evolutionarily conserved RBFOX family, has emerged as a critical splicing regulator, playing a pivotal role ...

Splicing factors control triple-negative breast cancer cell mitosis through SUN2 interaction and sororin intron retention

Journal of Experimental & Clinical Cancer Research, 2021
Background Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer with limited therapeutic opportunities. Recently, splicing factors have gained attention as potential targets for cancer treatment. Here we systematically evaluated
