The high morbidity and mortality of lung adenocarcinoma (LUAD) are partly caused by a lack of sensitive and reliable molecular markers for early diagnosis. Programmed cell death (PCD) is a crucial process involved in tumorigenesis and immune regulation, and identifying PCD-correlated genes may contribute to the precision diagnosis and targeted therapy of LUAD. LUAD samples were acquired from UCSC Xena and Gene Expression Omnibus (GEO) database.

Surface-confined DNA computing has emerged as a powerful information processing paradigm, offering enhanced specificity and accelerated reaction kinetics. Artificially designed DNA origami serves as a key enabler for such systems by providing a highly programmable platform for positioning computational components with nanometer resolution. However, conventional monolayer DNA origami circuits often exhibit non-negligible signal leakage, attributed to structural fluctuation-induced crosstalk between surface-confined molecules.

Nevertheless, implementing DNA circuits for such functions generally relies on the use of dual-rail expression that doubles the number of required gates, constraining the achievable complexity in a single solution. A fundamental limitation is that conventional single-rail circuits cannot support nonfirst-layer NOT operations.

DNA hybridization and assembly processes are governed by the concerted effects of Watson-Crick pairing and base-stacking interactions. While sequence engineering and chemical modifications have been extensively exploited to regulate DNA hybridization processes and complex structural assembly of DNA, here we demonstrate the use of locked nucleic acid (LNA) modifications to finely tune base-stacking interactions, which are yet to be explored in DNA assembly processes, to program the growth of self-assembled DNA crystals. We find that sticky-end LNA modifications decrease base-pair spacing and enhance base-stacking energy, which synergistically improves interstrand affinity and accelerates hybridization rate constants, as revealed by strand displacement kinetics, molecular dynamics simulations, and small-angle X-ray scattering analysis.

Targeted cancer therapy remains a significant challenge due to the complexity of tumor microenvironments and the need for precise drug delivery systems that can overcome these obstacles. To address this challenge, a nanoparticle platform based on prodrug activation and immune enhancement for "two-missile" targeting of TNBC has been developed: Azido-HA@CuO@DNA. This nanoparticle platform utilises azido hyaluronic acid (Azido-HA) as the primary carrier to enhance specificity to tumor tissues and targeting to tumor cells.

Tetrahedral DNA frameworks (TDFs) have been extensively utilized in biosensing systems. At the macroscopic level, it has been well established that TDFs, when employed as probe scaffolds, significantly enhance the interfacial DNA hybridization efficiency between target single-stranded DNA (ssDNA) and probe ssDNA at the solid-liquid interface. However, a molecular-level understanding of how TDF scaffolds facilitate this interfacial hybridization remains elusive.
