NM23-H1: a Metastasis-Associated Gene

Taiwanese Journal of Obstetrics & Gynecology, 2006
The protein product of nm23-H1 gene has activity of nucleoside diphosphate (NDP) kinase, which catalyzes the phosphorylation of nucleoside diphosphates to the corresponding nucleoside triphosphates.

Bis(benzoyloxybenzyl)-DiPPro Nucleoside Diphosphates of Anti-HIV Active Nucleoside Analogues

, 2015
Nucleoside analogues are extensively used as antiviral and anticancer agents. Their efficiency is dependent on their metabolism into the ultimately active nucleoside triphosphates.

Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing

Biological functions and clinical implications of the CMPK2 across multisystemic diseases

Cell & Bioscience
Cytidine/Uridine monophosphate kinase 2 (CMPK2) is a crucial enzyme responsible for the phosphorylation of nucleotides, specifically converting cytidine monophosphate (CMP) and uridine monophosphate (UMP) into their respective diphosphates, known as ...

Synthesis, cytostatic activity and inhibition of ribonucleotide reductase by 5'-phosphoramidates and 5'-diphosphates, of 2'-O-allyl- arabinofuranosyl nucleosides

, 1999
The diphosphates of a series of 2'-O-allyl-1-beta-D-arabinofuranosyl derivatives, previously obtained by us, have been prepared and tested for their inhibitory activity in an in vitro assay using R1 and R2 subunits of the purified recombinant mouse ...

p300 Degradation by the p53‐SIAH1 Axis Relieves TBK1 Acetylation to Enhance Innate Antiviral Immunity

Advanced Science, EarlyView.
This study identifies p300 as the acetyltransferase that acetylates TBK1 and inhibits its phosphorylation. Activation of the p53‐SIAH1 axis by immune response downregulates p300 expression to sustain innate antiviral immunity. Conditional p300 knockout in alveolar epithelial cells in vivo promotes antiviral responses and suppresses virus replication ...

Tandem Duplication‐Driven Neofunctionalization of UDP‐Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae

Advanced Science, EarlyView.
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

Electronic structure and atomic structure peculiarities of isomorphic modified zinc diphosphates

, 2014
Effects of partial substitution of Zn by Mn on the electronic and atomic structure of diphosphates Zn₂₋xMnxP₂O₇⋅5H₂O (x = 0.0, 0.7) have been studied out by X-ray photoelectron spectroscopy, IR spectroscopy, NMR and thermogravimetric analysis.

Mesoporous Silica Nanoparticles With Customized Drug Ratio/Loading for Effective Treatment of Gemcitabine‐Resistant Pancreatic Tumors

Advanced NanoBiomed Research, EarlyView.
Redox responsive mesoporous silica nanoparticles (MSNs) were engineered to deliver gemcitabine (Gem) and cisplatin (cisPt) at defined ratios to overcome chemoresistance in pancreatic ductal adenocarcinoma (PDAC). Optimized Gem MSNs and Gem cisPt MSNs enhanced cytotoxicity in murine and human Gem resistant models, with select formulations inducing ...
