Regulatory role of l-proline in fetal pig growth and intestinal epithelial cell proliferation

Animal Nutrition, 2020
l-proline (Pro) is a precursor of ornithine, which is converted into polyamines via ornithine decarboxylase (ODC). Polyamines plays a key role in the proliferation of intestinal epithelial cells.

Inhibition of the polyamine system counteracts β-amyloid peptide-induced memory impairment in mice: involvement of extrasynaptic NMDA receptors. [PDF]

PLoS ONE, 2014
In Alzheimer's disease (AD), the β-amyloid peptide (Aβ) has been causally linked to synaptic dysfunction and cognitive impairment. Several studies have shown that N-Methyl-D-Aspartate receptors (NMDAR) activation is involved in the detrimental actions of

Spermidine Reproduces the Anti‐Inflammatory Effects of Intermittent Fasting and Prevents Urate and Calcium Pyrophosphate Crystal‐Induced Inflammation

Arthritis &Rheumatology, Volume 78, Issue 2, Page 449-462, February 2026.
Objective Gout caused by the formation of monosodium urate (MSU) crystals and calcium pyrophosphate (CPP) deposition disease are two major types of microcrystalline pathologies in adults. They are responsible for recurrent flares that rely on interleukin (IL) 1β via activation of the NLRP3 inflammasome.

Microbial metabolites in tumor epigenetic regulation

iMeta, Volume 5, Issue 1, February 2026.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Pathogenic Significance of Trypanosomatids: Progress in Drug Resistance, Control Strategies, and Artificial Intelligence

Interdisciplinary Perspectives on Infectious Diseases, Volume 2026, Issue 1, 2026.
Trypanosomatids, including the genera Trypanosoma and Leishmania, are protozoan parasites of significant medical and veterinary relevance. These organisms cause African trypanosomiasis, Chagas disease, and leishmaniasis, which are classified as neglected tropical diseases (NTDs).

Molecular and cellular mechanisms underlying gyrate atrophy: Why is the retina primarily affected?

Acta Ophthalmologica, Volume 103, Issue 7, Page e436-e455, November 2025.
Abstract Gyrate atrophy of the choroid and retina (GACR; OMIM #258870) is a rare early‐onset autosomal recessive disorder, caused by bi‐allelic pathogenic variants in the gene coding for ornithine aminotransferase (OAT) resulting in hyperornithinaemia.

Sustained Delivery of Difluoromethylornithine (DFMO) by Means of Implantable Ceramic Devices

Journal of Investigative Surgery, 1988
A total of 25 Sprague-Dawley albino male rats were assigned to five groups, each group consisting of five rats. Polylactic acid-impregnated ALCAP capsules filled with 40 mg DFMO were implanted subcutaneously (sc) or intraperitoneally (ip) in group I and II rats, respectively.

ODC‐Driven Polyamines Synthesis Sustains the Self‐Renewal of Glioblastoma Stem Cells and Drives Tumor Aggressiveness

Cancer Science, Volume 116, Issue 11, Page 3079-3089, November 2025.
Our findings delineate a novel regulatory network that integrates metabolic and GSCs self‐renewal in GBM. By integrating genetic ODC ablation with multiomic profiling, we redefine polyamine metabolism as a linchpin of GSCs self‐renewal, a dependency exploitable through precision gene editing.

Integrating Metabolic Modulation and Nanomedicine for Cancer Immunotherapy

Advanced Science, Volume 12, Issue 40, October 27, 2025.
Metabolic rewiring in cancer is mapped across glucose, amino acid, lipid, nucleotide, and mitochondrial pathways, with emphasis on immune regulation. The review integrates mechanisms linking these pathways to tumor progression and therapy resistance, and profiles nanomaterial platforms that both deliver therapeutics and actively reprogram ...
