USP10 Inhibits Ferroptosis via Deubiquinating POLR2A in Head and Neck Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study identifies USP10 as a novel deubiquitinase that antagonizes ferroptosis in head and neck squamous cell carcinoma (HNSCC). Mechanistically, USP10 directly stabilizes POLR2A protein through post‐translational deubiquitination, enabling POLR2A‐mediated transcriptional activation of SLC7A11, a key ferroptosis inhibitor.

Role of the ubiquitin-selective CDC-48/UFD-1/NPL-4 chaperone in DNA replication [PDF]

, 2012
Faithful transmission of genomic information requires tight spatiotemporal regulation of DNA replication factors. Posttranslational modifications, such as ubiquitylation, constitute a fast and effective mechanism to control such complex protein function.

The effect of acceptor oligoribonucleotide sequence on the T4 RNA ligase reaction.

European Journal of Biochemistry, 1982
In order to make efficient use of T4 RNA ligase in a program involving chemical-enzymatic oligoribonucleotide synthesis, the sequence effects of the acceptor oligomer have been refined.

Revealing Cell‐Free Mitochondrial DNA Breakage Patterns as Novel Biomarkers for Sepsis

Advanced Science, EarlyView.
Uncovering distinct plasma cfmtDNA breakage patterns opens new frontiers for early sepsis detection and prognosis. Unique cleavage hotspots in RNR2 and COX2 regions outperform traditional biomarkers, while mechanistic insights suggest bacterial endonuclease involvement.

PTPN2 Inhibition Disrupts Mitochondrial Renewal and Blocks TFRC‐Mediated Mitophagy to Exert Anti‐Tumor Activities in ALK‐Positive Anaplastic Large Cell Lymphoma

Advanced Science, EarlyView.
CRISPR/Cas9 screening reveals PTPN2 as essential for ALK+ ALCL survival. PTPN2 regulates TFRC to promote PINK1‐PRKN mitophagy. Oral PTPN2 inhibitor ABBV‐CLS‐484 disrupts mitochondrial renewal and blocks TFRC‐mediated mitophagy to exert anti‐tumor activities, supporting clinical development for ALK+ ALCL.

The LINC01138 drives malignancies via activating arginine methyltransferase 5 in hepatocellular carcinoma

Nature Communications, 2018
Long intergenic non-coding RNAs have been linked to cancer development. Here the authors, using RNA-seq and genomic amplification data, identify lincRNAs deregulated in hepatocellular carcinoma and propose that Linc01138 is stabilized by IGF2BP1/3 in the

MYC Binding Near Transcriptional End Sites Regulates Basal Gene Expression, Read‐Through Transcription, and Intragenic Contacts

Advanced Science, EarlyView.
MYC is a transcription factor (TF) that binds DNA near transcriptional start sites (TSSs) and within enhancer elements. Here, unappreciated sites of MYC binding in the vicinity of transcriptional end sites (TESs) of many genes in multiple cell types in association with numerous other TFs are described previously.

Archaeal RNA ligase is a homodimeric protein that catalyzes intramolecular ligation of single-stranded RNA and DNA

Nucleic Acids Research, 2008
RNA ligases participate in repair, splicing and editing pathways that either reseal broken RNAs or alter their primary structure. Here, we report the characterization of an RNA ligase from the thermophilic archaeon, Methanobacterium thermoautotrophicum ...
