Functional Characterization of the Saccharomyces cerevisiae Equilibrative Nucleoside Transporter 1 (ScENT1)

Molecules, 2018
Equilibrative nucleoside transporters (ENTs) are polytopic membrane transporters responsible for the translocation of nucleosides, nucleobases—to a lesser extent—and nucleoside analog therapeutics across cellular membranes.

Weight gain among treatment-naïve persons with HIV starting integrase inhibitors compared to non-nucleoside reverse transcriptase inhibitors or protease inhibitors in a large observational cohort in the United States and Canada. [PDF]

, 2020
IntroductionWeight gain following antiretroviral therapy (ART) initiation is common, potentially predisposing some persons with HIV (PWH) to cardio-metabolic disease.

3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Biological Catalysis and Information Storage Have Relied on N-Glycosyl Derivatives of β-D-Ribofuranose since the Origins of Life

Biomolecules, 2023
Most naturally occurring nucleotides and nucleosides are N-glycosyl derivatives of β-d-ribose. These N-ribosides are involved in most metabolic processes that occur in cells.

Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

Advanced Materials, EarlyView.
How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.

Architecture of an All‐In‐One Microfluidic Platform for Accelerated Cancer Seeding, Enhanced Spheroid Formation, and Dynamic Drug Screening Trials

Advanced Materials Technologies, EarlyView.
An all‐in‐one microfluidic platform consists of two‐layered PDMS channels integrated with a hydrogel microwell array. This platform enables flow‐driven tumor cell capture, enhanced spheroid formation within the microwells, and advective drug testing. ABSTRACT Effective cancer drug screening requires platforms that replicate the physiological complexity

Nucleoside Diphosphate Prodrugs [PDF]

Nucleic Acids Symposium Series, 2008
Nucleoside analogs are widely applied in antiviral and antitumor therapy. A severe limitation of these compounds arises from the need of biotransformation to the eventually active nucleoside triphosphates by stepwise addition of phosphate by kinases. This problem can be circumvented by employing reversibly masked nucleotides (prodrugs).

Single‐Mitochondrion ATP Profiling Directs Discovery of Targetable OXPHOS Dependency in Cancers

Advanced Science, EarlyView.
MitoATP‐nFCM integrates nano‐flow cytometry with fluorogenic probes (ATP/membrane potential) and antibodies to quantify mitochondrial metabolites and protein expression at single‐organelle resolution, exposing oxidative phosphorylation (OXPHOS)‐driven metabolic rewiring in cancers.
