#1 [15.5] ShapeME: A Tool and Web Front-end for De Novo Discovery of Structural Motifs Underpinning Protein-DNA Interactions.

Determining where proteins bind a genome is paramount to understanding gene regulation. In addition to DNA sequence motifs, structural motifs (e.g., a narrow minor groove width) determine binding for some proteins (Rohs et al., 2009) [1]. Algorithms using structural features of DNA to predict protein binding exist (Mathelier et al., 2016; Samee ...

#2 [15.3] pH-dependent allosteric remodeling of a bacterial riboswitch couples alkaline activation to metal sensing.

The widespread yybP-ykoY riboswitches control bacterial manganese (Mn) homeostasis by activating exporter expression in response to intracellular Mn2+ levels. The Escherichia coli alx riboswitch distinctively couples Mn2+ sensing to cytoplasmic alkalinity, but the mechanism is unknown. We show that pH tunes the alx aptamer's conformational sampl...

#3 [14.7] Live imaging and interactome analysis of Zika and chikungunya viral RNAs via dual-action aptamer tag

Arthropod-borne, positive-sense RNA viruses encompass many human pathogens posing significant health threats worldwide. Understanding intracellular dynamics and host-factor interactions of the viral genome is essential for devising effective antiviral strategies. Here, we engineer dual-labeled Zika and chikungunya viruses incorporating a Mango-I...

#4 [14.5] Shared-Output Aptamer-Gated DNA Nanodevices Program NbaSPARDA Trans-Cleavage for Metabolite and Drug Sensing.

Routing chemically distinct small-molecule aptamers into a common nuclease trans-cleavage pathway is constrained by the target-specific output handles of conventional structure-switching aptamers (SSAs). Shared-output aptamer-gated DNA nanodevices are designed so that recognition cores control release of the same short trigger DNA (tDNA). The re...

#5 [14.3] Myelin-Inspired 3D PEGylation of Framework Nucleic Acids Enables Simultaneous Long Circulation and Rapid Renal Clearance.

The rational design of nanomedicines is fundamentally constrained by a physicochemical paradox at the bio-nano interface: strategies to prolong circulation inevitably suppress clearance, often resulting in long-term accumulation and systemic toxicity. To address this, we propose spatial conformation engineering as an additional design dimension ...

#6 [14.3] Modular Lysosome-Targeting Platform Based on a Multivalent DNA Framework for Programmable Protein Degradation.

Targeted degradation of extracellular and membrane-bound proteins holds immense therapeutic potential but remains technically challenging. Lysosome-targeting chimeras (LYTACs) have emerged to bridge this gap, yet platforms built on monomeric aptamers suffer from inadequate stability, inefficient cellular uptake, and a lack of modularity. Here, w...

#7 [13.9] An engineered nanopore identifies saccharides, amino acids, peptides and ribonucleotides

#8 [13.9] A Sprayable Multifunctional Film Based on EGFR-Targeting DNA Nanoactivators for Burn Wound Healing.

Burn treatment remains a tough clinical hurdle, as traditional epidermal growth factor (EGF) treatments suffer from rapid proteolytic degradation and poor skin permeation. Herein, a sprayable, multifunctional film (STAR) based on EGFR-targeting DNA nanoactivators is reported for efficient burn wound healing. The STAR platform combines tannic aci...

#9 [13.7] Leukemic Stem Cell-Targeted Liposomal Nanoimmunotherapy Reverses Immune Evasion and Inhibits Fusion Oncoprotein-Driven Acute Myeloid Leukemia by Silencing B-Cell Lymphoma 2.

Acute Myeloid Leukemia (AML) is a prevalent and aggressive hematologic cancer driven by leukemic stem cells and immune evasion. Among its subtypes, Mixed Lineage Leukemia-AF9 (MLL-AF9)- rearranged AML is exceptionally lethal, with B-cell lymphoma 2 (Bcl2), a key anti-apoptotic protein, supporting leukemic survival and immune dysfunction. Targeti...
