Design of a Novel Diamine Biosensor to Guide the Engineering of Escherichia coli for Cadaverine Overproduction

Advanced Science, EarlyView.
A high‐throughput screening platform was established by integrating an in vivo cadaverine biosensor with a fluorescence‐activated cell sorting (FACS) system. Biosensor‐driven specific exporter tuning, pathway optimization and genome‐wide target mining were conducted to maximize cadaverine production in Escherichia coli.

Contribution of Cytidine Deaminase to Thymidylate Biosynthesis in Trypanosoma brucei: Intracellular Localization and Properties of the Enzyme

mSphere, 2019
Cytidine deaminase (CDA) is a pyrimidine salvage enzyme that catalyzes cytidine and deoxycytidine hydrolytic deamination to yield uridine and deoxyuridine.

MAPA: A Semantic Network Framework for Functional Module Discovery and Interpretation in Multi‐Omics Data

Advanced Science, EarlyView.
MAPA transforms complex multi‐omics data into biologically coherent functional modules by integrating pathway information with molecular interaction networks. Retrieval‐augmented large language models then generate structured, literature‐informed interpretations.

Profile of Nucleotides and Nucleosides in Taiwanese Human Milk

Pediatrics and Neonatology, 2011
Human milk–borne nucleotides and their related metabolic products have been reported to have important physiological roles in breast-fed infants. The purpose of this study was to measure the concentrations of free nucleotides and nucleosides in human ...

Epigenetic Silencing of CYYR1 Promotes Lung Adenocarcinoma Progression Through TRIM21‐Dependent Regulation of HMMR Stability

Advanced Science, EarlyView.
CYYR1 as an epigenetically dysregulated tumor‐suppressive factor that influences oncoprotein stability through TRIM21‐dependent HMMR regulation and reveals a potential therapeutic vulnerability in CYYR1‐deficient LUAD. The graphical illustration was created using FigDraw (www.figdraw.com).

Selective prebiotic synthesis of α‐threofuranosyl cytidine by photochemical anomerization [PDF]

, 2021
The structure of life’s first genetic polymer is a question of intense ongoing debate. The ‘RNA world theory’ suggests RNA was life’s first nucleic acid. However, ribonucleotides are complex chemical structures, and simpler nucleic acids, such as threose

Effect of Human MTHFR Gene Polymorphisms in Morbidly Obese Population on Elevate Risk of Type 2 Diabetes

Nano Biomedicine and Engineering, 2018
In this paper, based on the association of methylenetetrahydrofolate reductase (MTHFR) with type 2 diabetes (T2D), we evaluated the association of polymorphism with morbidly obesity on risk type 2 diabetes.

GSLR Drives Lung Adenocarcinoma as a Critical Regulator of Energy Homeostasis Through Creatine Kinase B Activation

Advanced Science, EarlyView.
This study identifies the glucose/glutamine sensitive lncRNA GSLR as a driver of lung adenocarcinoma progression. Nutrient restriction reduces chromatin accessibility at the GSLR locus and blocks CTCF‐mediated transcriptional regulation. GSLR directly interacts with DHX9 and recruits it to the CKB promoter, arresting R‐loop accumulation and promoting ...
