NDFIP2 Suppresses Colorectal Cancer Metastasis Through DDX3X‐Dependent R‐Loop Remodeling and GNG13 Transcriptional Activation

Advanced Science, EarlyView.
NDFIP2 recruits NEDD4 to promote K48‐linked ubiquitination and proteasomal degradation of DDX3X, leading to R‐loop accumulation and CTCF‐dependent suppression of GNG13 transcription. Consequently, PI3K/AKT signaling, EMT, stemness, and colorectal cancer metastasis are inhibited.

A DNA G‐Quadruplex‐Targeting Ligand Suppresses c‐MYC Expression: Implications for Gemcitabine‑Resistant Pancreatic Cancer

Angewandte Chemie, EarlyView.
PQB‐4, a fluorescent small‐molecule ligand that targets c‐MYC DNA G‐quadruplexes (G4s), showed marked synergy with gemcitabine in resistant PANC‐1 cells (CI = 0.027). In vivo, the ligand reduced tumor weight by 44% in a PANC‐1 xenograft model. These results highlight the therapeutic potential of c‐MYC DNA G4‐targeting ligands for treating gemcitabine ...

DUSP26 Regulated by YY1 Lactylation Couples Osteogenesis and Angiogenesis by Dephosphorylating PMPCB at Y141 and Activating Mitophagy in BMSCs

Advanced Science, EarlyView.
p300‐associated YY1 lactylation promotes DUSP26 expression in BMSCs. By regulating PMPCB phosphorylation and PINK1 processing, DUSP26 supports mitophagy, osteogenic differentiation, and pro‐angiogenic factor secretion. BMSC‐derived exosomes carrying a RUNX2 promoter‐driven DUSP26 plasmid favor osteogenic‐lineage transgene expression, partially ...

Chemoenzymatic Synthesis of 6‐Sulfo Sialyl Lewisx Containing Glycans to Probe the Receptor Specificity of MERS Coronavirus

Angewandte Chemie, EarlyView.
A chemoenzymatic methodology is described that provided a panel of 6‐sulfo sialyl Lewisx‐containing glycans that were probed for receptor specificity of MERS‐CoV. Although the fucoside of 6‐sulfo‐SLex does not directly interact with the spike, it pre‐organizes the molecule into a conformation to allow a salt bridge between the sulfate and the ...

Topology‐Driven X‐Shaped DNA as a cGAS Stimulator to Promote Dendritic Cell Activation and Antitumor Vaccine Efficacy

Advanced Science, EarlyView.
X‐shaped DNA promotes multivalent cGAS assembly and enhances cGAS‐STING signaling. When conjugated with antigenic peptides, the resulting X‐DNA‐based peptide vaccine promotes dendritic cell activation, antigen presentation, and antitumor T‐cell responses.

A UBE3A‐UTX Proteostasis‐Epigenetic Axis Governs Hypothalamic Energy Homeostasis

Advanced Science, EarlyView.
Ubiquitin protein ligase E3A (UBE3A) regulates hypothalamic energy homeostasis and promotes degradation of the histone demethylase UTX (KDM6A). Neuronal UBE3A loss increases susceptibility to diet‐induced obesity and is accompanied by UTX accumulation, reduced histone H3 lysine 27 trimethylation, and altered endoplasmic reticulum stress‐responsive gene

Combinatorial Tuning of Multigene Biosynthetic Pathways based on RNA Interference

Advanced Science, EarlyView.
Small RNA sequencing identifies candidate endogenous Pol III promoters, and subsequent fluorescence screening measures knockdown efficiency to assess promoter strength. Combining promoter strength and shRNA target position enables fine‐grained RNAi regulation of multigene pathways. This strategy enhances β‐carotene production in Schizochytrium sp.
