Genetic and Phenotypic Features of the Five Known Polyaminopathies: A Critical Narrative Review

American Journal of Medical Genetics Part A, Volume 200, Issue 5, Page 993-1003, May 2026.
ABSTRACT Polyaminopathies are a recently described family of rare genetic neurodevelopmental disorders. Polyaminopathies disrupt the biosynthesis of the primary polyamines: putrescine, spermidine, and spermine. Snyder–Robinson syndrome results from hemizygous loss‐of‐function variants in the spermine synthase (SMS) gene, resulting in decreased or ...

Effect of polyamine biosynthesis inhibitors on in vitro growth of Phyllosticta antirrhini Sydow and on the infection of Antirrhinum majus L. by the pathogen

Acta Agrobotanica, 2013
Polyamine biosynthesis inhibitors, DL-α-difluromethylornithine (DFMO) and DL-α-difluromethylarginine (DFMA) at concentrations of 1,0 and 3,0 mM greatly inhibited mycelial growth of Phyllosticta antirrhini on Czapek Dox Agar (CDA).

Efferocytosis: Signaling Pathways and New Therapeutic Strategies for Diseases

MedComm, Volume 7, Issue 5, May 2026.
1. Efferocytosis coordinates molecular signaling and metabolic reprogramming to resolve inflammation. 2. Efferocytosis dysfunction underlies four conserved pathological hallmarks across diseases. 3. Therapeutic strategies targeting efferocytosis should be context‐dependent: enhance or inhibit based on disease type. ABSTRACT Efferocytosis—the phagocytic

Familial Adenomatous Polyposis—Risk of Cancer, Cancer Prevention, and Long‐Term Consequences: Learnings from Five Decades with the Danish Polyposis Register

APMIS, Volume 134, Issue 5, May 2026.
ABSTRACT Familial adenomatous polyposis (FAP) is a hereditary condition marked by the growth of hundreds to thousands of adenomatous polyps in the colon and rectum, significantly elevating the risk of colorectal cancer (CRC) if left untreated. Caused by pathogenic variants in the APC gene, FAP is typically identified in adolescence, often leading to ...

In vitro and in vivo studies on exogenous polyamines and α-difluoromethylornithine to enhance bone formation and suppress osteoclast differentiation

Amino Acids
Exogenous polyamines, including putrescine (PUT), spermidine (SPD), and spermine (SPM), and the irreversible inhibitor of the rate-limiting enzyme ornithine decarboxylase (ODC) of polyamine biosynthesis, α-difluoromethylornithine (DFMO), are implicated ...

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.
