Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics
Angewandte Chemie, EarlyView.Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Advanced Science, EarlyView.Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...

Angewandte Chemie, EarlyView.The azacitidine biosynthetic gene cluster (aza BGC) was identified by the resistance‐gene‐guided comparative genomics method in Streptomyces mobaraensis IPIO2. The complete biosynthetic pathway of azacitidine, which follows a “base‐first‐then‐glycosylation” logic, was elucidated through in vivo and in vitro experiments.

Advanced Science, EarlyView.Incomplete microwave ablation induces animmunosuppressive microenvironment in tumor‐draining lymph nodes. An albumin‐based lipoprotein nanosystem enables coordinated delivery of immunomodulators to tumor‐draining lymph nodes and residual tumors, reverses post‐ablation immunosuppression, suppresses residual tumor growth, and promotes durable antitumor ...

Cytosine-5-methyltransferases add aldehydes to DNA.
, 2009 Targeted methylation of cytosine residues by S-adenosylmethionine–dependent DNA methyltransferases modulates gene expression in vertebrates. Here we show that cytosine-5-methyltransferases catalyze reversible covalent addition of exogenous aliphatic ...

Activity on non-methylated DNA limits the use of endonuclease MspJI for epigenetic analyses
All Results Journals: Biol, 2018 Cytosine methylation of DNA in mammals has been associated with both physiological and pathological changes in gene-expression. DNA treatment with methylation sensitive and/or dependent restriction enzymes, followed by PCR amplification is a widely used ...

Advanced Science, EarlyView.A living multi‐omics sarcoma PDX biobank is enriched for high‐risk disease and preserves key patient tumor features at histopathological and molecular levels. Integrated profiling reveals ecDNA‐driven oncogene amplification in osteosarcoma and preferential retention of ecDNA during PDX evolution.

Advanced Science, EarlyView.Schematic illustration of the CALCas system, in which a conformational switch in the 3' terminal DNA extension of scaffold RNA (3'D‐SR) drives cascade‐activatable Cas12a cleavage while suppressing leakage. ABSTRACT Amplification‐free CRISPR detection has attracted significant attention for its capacity to circumvent the intricacies of nucleic acid ...
