Transport in hybrid electronic devices based on a modified DNA nucleoside (deoxyguanosine) [PDF]
arXiv, 2000 We report on a new class of hybrid electronic devices based on a DNA nucleoside (deoxyguanosine lipophilic derivative) whose assembled polymeric ribbons interconnect a submicron metallic gate. The device exhibits large conductivity at room temperature, rectifying behaviour and strong current-voltage hysteresis.

Advanced Science, EarlyView.Synthetic gene circuits regulated by bezafibrate are developed to express tumor antigens and PD‐L1 nanobody (PD‐L1nb), enhancing cancer immunotherapy. Delivered via HEK293T cells, ESCs, or directly injected the plasmids containing the circuit into the tumor, the circuits reduce tumor growth, boost CD8+ T cells, and minimize T cell exhaustion.

Antiviral Activity of 4'-thioIDU and Thymidine Analogs against Orthopoxviruses
Viruses, 2010 The search for effective therapies for orthopoxvirus infections has identified diverse classes of molecules with antiviral activity. Pyrimidine analogs, such as 5-iodo-2'-deoxyuridine (idoxuridine, IDU) were among the first compounds identified with ...

Time-Resolved Emission Study of a Thiophene-Modified Fluorescent Nucleoside in Solution and within Multiply-Modified Oligodeoxynucleotides [PDF]
arXiv, 2014 Steady-state and time-resolved emission techniques were employed to study the photophysical properties of 5-(thien-2-yl)-2'-deoxyuridine (dUTh), an isomorphic fluorescent nucleoside analog. We found that the emission lifetime of dUTh is dependent upon the solvent viscosity and obeys the F\"orster-Hoffman relation over a wide range of temperatures in 1 ...

HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis
Advanced Science, EarlyView.Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

Biosynthetic and Synthetic Strategies for Assembling Capuramycin-Type Antituberculosis Antibiotics
Molecules, 2019 Mycobacterium tuberculosis (Mtb) has recently surpassed HIV/AIDS as the leading cause of death by a single infectious agent. The standard therapeutic regimen against tuberculosis (TB) remains a long, expensive process involving a multidrug regimen, and ...

Stepping and crowding of molecular motors: statistical kinetics from an exclusion process perspective [PDF]
, 2013 Motor enzymes are remarkable molecular machines that use the energy derived from the hydrolysis of a nucleoside triphosphate to generate mechanical movement, achieved through different steps that constitute their kinetic cycle. These macromolecules, nowadays investigated with advanced experimental techniques to unveil their molecular mechanisms and the

Salvage enzymes in nucleotide biosynthesis [PDF]
, 2007 Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Nucleoside Transporter Proteins
Current Vascular Pharmacology, 2009 Concentrative nucleoside transporters (CNT; SLC28) and equilibrative nucleoside transporters (ENT; SLC29) mediate the uptake of natural nucleosides and a variety of nucleoside-derived drugs, mostly used in anticancer therapy. SLC28 and SLC29 families consist in three and four members, respectively, which differ in their substrate selectivity and their ...
