Advanced Science, EarlyView.Circular RNA circFOXK2 is frequently upregulated in pancreatic ductal adenocarcinoma to promote tumor heterogeneity, growth, and metastasis. Through circRNA‐DNA interaction at different genomic locations, circFOXK2 removes the PPIE inhibitory effects on MLL1 for gene‐activating H3K4 methylation of the oncogenes.

Advanced Science, EarlyView.Proposed molecular mechanism: NSUN6 catalyzes m5C methylation on Snail mRNA to enhance its stability, leading to Snail upregulation and EMT promotion. The first‐in‐class inhibitor AL398 suppresses endometrial cancer metastasis by targeting the NSUN6‐m5C‐Snail. axis. ABSTRACT Endometrial cancer (EC) constitutes a leading gynecologic malignancy for which

Synthesis and Antiviral Evaluation of Certain Novel Pyrazinoic Acid C-Nucleosides
, 2016 Pyrazine (1,4-diazine) C-nucleosides constitute a rare class of nucleic acid analogues that has only recently been reported in the literature. As part of our ongoing investigation into the synthesis and reactivity of these compounds, we have developed ...

Advanced Science, EarlyView.CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

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.This work develops a metabolic sharing strategy that employs cytidine monophosphate (CMP) to competitively reprogram floxuridine (FUDR) pyrimidine metabolism in colorectal tumor cells. Elevated intracellular FdUMP induces nucleotide imbalance, drives mitochondrial DNA release and cGAS‐STING innate immune cascade activation, and potentiates robust ...
