NAD+‐Boosters Improve Mitochondria Quality Control In Parkinson's Disease Models Via Mitochondrial UPR

Advanced Science, EarlyView.
Treatment of MPTP‐incubated cells with NAD+‐boosters increase the UPRmt/mitophagy‐related mitochondria quality control (MQC). Disturbed plasma UPRmt‐mitophagy‐mediated MQC profiles in PD patient samples. NMN inhibits motor deficit and forestalls neuropathology phenotypes of PD mice, which is required the atf4‐medicated UPRmt pathway.

Smc5/6: a link between DNA repair and unidirectional replication? [PDF]

, 2008
Of the three structural maintenance of chromosome (SMC) complexes, two directly regulate chromosome dynamics. The third, Smc5/6, functions mainly in homologous recombination and in completing DNA replication.

Tryptophan Metabolite Indole‐3‐Aldehyde Induces AhR and c‐MYC Degradation to Promote Tumor Immunogenicity

Advanced Science, EarlyView.
Tryptophan metabolite Indole‐3‐aldehyde (I3A) downregulates cytosolic AhR and p‐ERK/c‐MYC proteins, together enhancing STAT3 phosphorylation and tumor immunogenicity. Overexpression of the Trp metabolic enzyme interleukin‐4‐induced gene‐1 (IL4I1) in tumor cells increases intracellular levels of I3A and enhances tumor immunogenicity.

Biochemical and Genetic Studies of UBR3, a Ubiquitin Ligase with a Function in Olfactory and Other Sensory Systems [PDF]

, 2007
Our previous work identified E3 ubiquitin ligases, termed UBR1-UBR7, that contain the ~70-residue UBR box, a motif important for the targeting of N-end rule substrates.

An RNA Ligase Essential for RNA Editing and Survival of the Bloodstream Form of Trypanosoma brucei

Science, 2001
RNA editing in trypanosomes occurs by a series of enzymatic steps that are catalyzed by a macromolecular complex. The TbMP52 protein is shown to be a component of this complex, to have RNA ligase activity, and to be one of two adenylatable proteins in ...

Branched‐Chain α Keto‐Acid Dehydrogenase Kinase‐Mediated AKT Phosphorylation Promotes RCC Tumorigenesis and Drug Resistance

Advanced Science, EarlyView.
This study identifies a novel oncogenic role and a previously unrecognized phosphorylation substrate of BCKDK in RCC, wherein it promotes tumor progression and drug resistance through AKT phosphorylation at both Thr308 and Ser473 sites and activation of AKT/mTOR and AKT/ABCB1 signaling pathways, offering a promising prognostic marker and therapeutic ...

Acod1 Promotes PAD4 Ubiquitination via UBR5 Alkylation to Modulate NETosis and Exert Protective Effects in Sepsis

Advanced Science, EarlyView.
In this study, Acod1 knockout in CLP mice significantly increases peripheral blood NET levels, exacerbating inflammation, organ damage, and reducing survival. Further research shows that UBR5 interacts with PAD4, a key NET formation protein. Acod1/itaconate (ITA) enhances the enzymatic activity of UBR5 by alkylating the Cys2768 site, promoting the K48 ...

Mapping the 5' and 3' ends of Tetrahymena thermophila mRNAs using RNA ligase mediated amplification of cDNA ends (RLM-RACE).

Nucleic Acids Research, 1993
A procedure is described for mapping the ends of RNAs. Using T4 RNA ligase, a DNA (3' end) or RNA (5' end) oligonucleotide is ligated to RNA ends followed by cDNA synthesis, PCR amplification, cloning and sequencing.
