Structural Probing and Molecular Modeling of the A3 Adenosine Receptor: A Focus on Agonist Binding

Molecules, 2017
Adenosine is an endogenous modulator exerting its functions through the activation of four adenosine receptor (AR) subtypes, termed A1, A2A, A2B and A3, which belong to the G protein-coupled receptor (GPCR) superfamily.

Nucleoside Triphosphate-Nucleoside Diphosphate Transphosphorylase (Nucleoside Diphosphokinase)

Journal of Biological Chemistry, 1964
Abstract Previous physical studies from this laboratory by sedimentation velocity and diffusion and by sedimentation equilibrium (Yue, R. H., Ratliff, R. L., and Kuby, S. A. (1967) Biochemistry 6, 2923–2932) have permitted an assignment of the kinetic molecular weight of the crystalline brewers' yeast nucleoside diphosphokinase, namely 102,000 (±2,000)

Enzalutamide‐Resistant STEAP4+ MyoCAF Secrete Phosphatidylcholine to Foster Progression by Activating Stemness in Hormone‐Sensitive Prostate Cancer

Advanced Science, EarlyView.
Expanding enzalutamide (ENZ) use in hormone‐sensitive prostate cancer (HSPC) faces resistance. Single‐cell profiling identifies therapy‐resistant STEAP4+ myofibroblastic cancer‐associated fibroblast (SETAP4+ myoCAF). These myoCAFs drive resistance via TFE3‐mediated autophagy and PCYT1A‐led phosphatidylcholine overproduction, creating a phospholipid ...

Sequence‐Specific Installation of Aryl Groups in RNA via DNA‐Catalyst Conjugates

Angewandte Chemie, EarlyView.
DNA oligonucleotides carrying amine nucleophilic catalysts are employed to deliver aryl groups to complementary sites in RNA under physiological conditions. The strategy can be used to sequence‐specifically label protein‐coding RNAs, or to knock down expression selectively, with potential applications in basic transcriptome research and in future ...

Effect of uridine protecting groups on the diastereoselectivity of uridine-derived aldehyde 5’-alkynylation

Beilstein Journal of Organic Chemistry, 2017
The 5’-alkynylation of uridine-derived aldehydes is described. The addition of alkynyl Grignard reagents on the carbonyl group is significantly influenced by the 2’,3’-di-O-protecting groups (R1): O-alkyl groups led to modest diastereoselectivities (65 ...

Distinct Phage‐Encoded Enzymes for Substitution of Deoxythymidine by Deoxyuridine in Phage Genomes

Advanced Science, EarlyView.
Distinct enzymes including dCTP deaminases (Dcds), dTMP phosphatases (Dtms), and dTTP pyrophosphatases (Dtt) are found to be responsible for dU‐DNA biosynthesis in the phages PBS1, DSS3_VP1, and PhiR1‐37. Both PhiR1‐37‐derived and synthetic dU‐DNA are resistant to cleavage by restriction enzymes and Cas12a nuclease targeting dT‐containing sites.

MUC15 Ectodomain Architecture Regulates Integrin Clustering to Control Cancer Metastasis

Advanced Science, EarlyView.
This study uncovers a size‐dependent adhesion paradigm, demonstrating that the glycocalyx protein MUC15 suppresses pancreatic cancer progression by attenuating integrin activation, focal adhesion assembly, and YAP mechanotransduction. Integrating computational modeling and experimental validation, the work reveals a mechanical mechanism by which MUC15 ...

Tumor Microenvironment‐Responsive Nanomedicines for Potentiating Cancer Immunotherapy

Advanced Science, EarlyView.
Strategies for TME‐responsive Nanomaterials to Potentiate Cancer Immunotherapy. Abstract Immunotherapy has emerged as a transformative paradigm in oncology, yet its clinical efficacy remains constrained by the immunosuppressive tumor microenvironment and inadequate spatiotemporal control of existing modalities, resulting in suboptimal patient response ...

Love Acoustic Wave-Based Devices and Molecularly-Imprinted Polymers as Versatile Sensors for Electronic Nose or Tongue for Cancer Monitoring

Sensors, 2016
Cancer is a leading cause of death worldwide and actual analytical techniques are restrictive in detecting it. Thus, there is still a challenge, as well as a need, for the development of quantitative non-invasive tools for the diagnosis of cancers and ...
