Pseudouridines in spliceosomal snRNAs [PDF]

Protein & Cell, 2011
Spliceosomal RNAs are a family of small nuclear RNAs (snRNAs) that are essential for pre-mRNA splicing. All vertebrate spliceosomal snRNAs are extensively pseudouridylated after transcription. Pseudouridines in spliceosomal snRNAs are generally clustered in regions that are functionally important during splicing.

Lactylated SPTAN1 Accelerates Hepatocellular Carcinoma Progression by Promoting NOTCH1/HES1 Activation and Immunosuppression

Advanced Science, EarlyView.
This study identifies SPTAN1‐kla as a novel oncogenic driver in HBV‐driven HCC, linking metabolic, epigenetic, and immune mechanisms. SPTAN1‐kla promotes HCC progression via NOTCH1/HES1 activation and immunosuppression. Findings highlight that targeting SPTAN1‐kla provides a framework for HCC treatment to improve clinical outcomes in HBV infected ...

Lactylation‐Driven YTHDC1 Alleviates MASLD by Suppressing PTPN22‐Mediated Dephosphorylation of NLRP3

Advanced Science, EarlyView.
In MASLD, YTHDC1 undergoes increased lactylation and ubiquitination, reducing its expression. AARS1 mediates lactylation at lysine 565, while disrupted binding to LDHA further promotes lactylation, suppressing YTHDC1. This downregulation enhances PTPN22 mRNA stability, leading to NLRP3 dephosphorylation and activation, which exacerbates inflammation ...

Myeloid neoplasms with isolated isochromosome 17q: a yet to be defined entity

Mediterranean Journal of Hematology and Infectious Diseases, 2017
It has been suggested that myeloid neoplasms with isolated isochromosome 17q[MN i(17q)] comprise a distinct entity with poor prognosis. However, literature reports show a considerable clinical and molecular heterogeneity.

Proteogenomic Characterization Reveals Subtype‐Specific Therapeutic Potential for HER2‐Low Breast Cancer

Advanced Science, EarlyView.
Multiomic profiling of HER2‐low breast cancer identifies three proteomic subtypes with distinct therapeutic strategies: endocrine, antiangiogenic, and anti‐HER2 therapies. Genomic and lactate modification landscapes are detailed, providing insights for precise management.

Interaction of eukaryotic translation initiation factor 4G with the nuclear cap-binding complex provides a link between nuclear and cytoplasmic functions of the m7 guanosine cap [PDF]

, 2001
In eukaryotes the majority of mRNAs have an m7G cap that is added cotranscriptionally and that plays an important role in many aspects of mRNA metabolism.

Mechanism of spliceosome remodeling by the ATPase/helicase Prp2 and its coactivator Spp2

Science, 2020
Remodeling an RNA processing machine Splicing of precursor messenger RNA (pre-mRNA) is carried out by the spliceosome, a highly dynamic, supramolecular complex that undergoes assembly, activation, catalysis, and disassembly.

Dual Targeting of Mutant p53 and SNRPD2 via Engineered Exosomes Modulates Alternative Splicing to Suppress Ovarian Cancer

Advanced Science, EarlyView.
Mutant p53 drives oncogenic splicing to promote the progression of ovarian cancer by partnering with the spliceosome factor SNRPD2. Therefore, it is engineered iRGD‐exosomes to co‐deliver siRNAs against both targets. This approach restored tumor‐suppressive mRNA isoforms, effectively enhanced sensitivity to cisplatin, and ultimately blocked tumor ...

Control of 3′ splice site selection by the yeast splicing factor Fyv6

eLife
Pre-mRNA splicing is catalyzed in two steps: 5ʹ splice site (SS) cleavage and exon ligation. A number of proteins transiently associate with spliceosomes to specifically impact these steps (first and second step factors).
