CircTP53/USP10/p53 signaling Axis as a Novel Regulator of Progression and Prognosis of Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
The study identifies a novel circular RNA derived from the TP53 gene (circTP53), which is upregulated in HNSCC and correlates with poor patient prognosis. It demonstrates that circTP53 promotes HNSCC progression by interacting with USP10, stabilizing both proteins, enhancing deubiquitination of p53, and thereby influencing tumor growth, with its ...

PRMT1‐Mediated SWI/SNF Complex Recruitment via SMARCC1 Drives IGF2BP2 Transcription to Enhance Carboplatin Resistance in Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
PRMT1 drives carboplatin resistance and tumor progression in head and neck squamous cell carcinoma (HNSCC) through a novel, methyltransferase‐independent mechanism. It recruits the SWI/SNF complex to activate IGF2BP2, promoting tumor growth and carboplatin resistance. PBX2 upregulates PRMT1, reinforcing this pathway. This study uncovers a non‐catalytic

Evolutionary relationships among group II intron-encoded proteins and identification of a conserved domain that may be related to maturase function.

Nucleic Acids Research, 1993
Many group II introns encode reverse transcriptase-like proteins that potentially function in intron mobility and RNA splicing. We compared 34 intron-encoded open reading frames and four related open reading frames that are not encoded in introns.

Accounting for ALA Natural Mutations Enhances the Efficiency of Graphene Oxide Nanopriming in Bar‐Modified Arabidopsis

Advanced Science, EarlyView.
Nanopriming enhances plant resilience to environmental challenges; however, its effectiveness across diverse genetic backgrounds, including genetic modifications and natural variations, remains uncertain. These findings demonstrate that nanopriming improves efficacy when natural genetic variations are considered, particularly in genetically modified ...

The Ll.LtrB intron from Lactococcus lactis excises as circles in vivo: insights into the group II intron circularization pathway

RNA: A publication of the RNA Society, 2015
Group II introns are large ribozymes that require the assistance of intron-encoded or free-standing maturases to splice from their pre-mRNAs in vivo. They mainly splice through the classical branching pathway, being released as RNA lariats.

Diversity, mobility, and structural and functional evolution of group II introns carrying an unusual 3' extension

BMC Research Notes, 2011
Background Group II introns are widespread genetic elements endowed with a dual functionality. They are catalytic RNAs (ribozymes) that are able of self-splicing and they are also mobile retroelements that can invade genomic DNA.

EccDNA‐Driven VPS41 Amplification Alleviates Genotoxic Stress via Lysosomal KAI1 Degradation

Advanced Science, EarlyView.
Following ionizing radiation, eccDNA‐mediated VPS41 amplification slightly increases its expression but fails to prevent apoptosis. Introducing exogenous eccDNA or VPS41 enhances VPS41‐KAI1 interaction, promoting lysosomal degradation of KAI1. This process inhibits apoptotic signaling, enhancing cell survival and resistance to radiation‐induced damage.
