PERCC1‐associated enteropathy: Diagnostic challenges and enteral autonomy achieved with teduglutide

JPGN Reports, EarlyView.
Abstract Congenital diarrheas and enteropathies (CODE) are rare inherited disorders characterized by early‐onset intractable diarrhea. Though progress has been made in elucidating the genetic basis of CODE, much remains to be discovered. Another challenge is the lack of curative therapies—treatment is primarily supportive including enteral and ...

Pyrrolopyrimidines: Design, Synthesis and Antitumor Properties of Novel Tricyclic Pyrrolo [2,3-d]pyrimidine Derivatives

Molecules
The pyrrolo[2,3-d]pyrimidine (7-deazapurine) scaffold is a unique heterocyclic system included in the composition of most nucleotides. In this study, series of the pyrrolo[2,3-d]pyrimidine-imines and 3-halo-substituted pyrrolo[2,3-d]pyrimidines were ...

Identification of Natural and Artificial Modifications in DNA at the Nanometer Level

Journal of Raman Spectroscopy, EarlyView.
Short single‐ and double‐stranded DNA sequences with natural and artificial markers are examined at ambient conditions using TERS to identify and localize the labelled nucleobases. The differences between single‐ and double‐stranded DNA should provide clear experimental evidence of the extreme surface sensitivity of TERS.

CRISPR Enabled Precision Oncology: From Gene Editing to Tumor Microenvironment Remodeling

Med Research, EarlyView.
CRISPR technology has progressed from a prokaryotic immune system to a diverse suite of editing platforms, including Cas nucleases, base and prime editors, and RNA‐targeting enzymes. These advances enable precise genomic and epigenomic interventions, high‐throughput functional screening, and immune engineering.

The ketogenic diet alters microbiome‐metabolome profiles to improve West syndrome therapy

Pediatric Investigation, EarlyView.
The ketogenic diet alleviates West syndrome by reshaping gut microbiota (increasing Bacteroides, Parabacteroides, and reducing Escherichia and Bifidobacterium), and modulating metabolites—including anticonvulsant lipids (e.g., capric acid), suppressed harmful lipids (e.g., 2‐methylbutyroylcarnitine), and amino acids and analogs (e.g., 3‐sulfinoalanine)—

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Research development of the relationship between thymidine phosphorylase expression and colorectal carcinoma

Cancer Biology & Medicine, 2013
Thymidine phosphorylase (TP) is a key enzyme that contributes to the composition and decomposition of pyrimidine nucleotides. TP seems homologous to platelet-derived endothelial cell growth factor, and its effects on inducing vascularization and anti ...

Mesenchymal stromal cell therapy for rheumatoid arthritis: Long‐term efficacy, safety, and mechanistic insights

Rheumatology &Autoimmunity, EarlyView.
Graphical abstract summarizing the multifactorial pathogenesis of rheumatoid arthritis (RA) and the therapeutic potential of mesenchymal stromal cell (MSC) therapy. MSCs provide promising benefits through their immunomodulatory properties, low immunogenicity, ability to promote tissue repair, and multi‐lineage differentiation, presenting a potential ...

Pyrimidine nucleotide synthesis in Pseudomonas nitroreducens and the regulatory role of pyrimidines

Microbiological Research, 2014
Control of pyrimidine biosynthesis in the commercially important, hydrocarbon-utilizing bacterium Pseudomonas nitroreducens ATCC 33634 was investigated. When glucose-grown wild-type cells were supplemented with uracil or orotic acid, the pyrimidine biosynthetic activities were depressed.
