Efferocytosis‐Driven Polyamine Metabolism in Macrophages Enhances Cancer Stem Cell Enrichment after Chemotherapy in Ovarian Cancer

Advanced Science, EarlyView.
Chemotherapy‐induced efferocytosis drives ovarian cancer stem cell enrichment. By engulfing apoptotic cancer cells, macrophages upregulate ODC1 and produce putrescine, which elevates osteopontin (OPN) expression. Secreted OPN then activates the CD44 receptor on cancer cells, promoting stemness and chemoresistance.

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

American Journal of Medical Genetics Part A, EarlyView.
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 ...

Synthesis and Evaluation of the First Generation of Glycosylated Nucleoside Analogues as Potential Inhibitors of the Base J Metabolism in Kinetoplastid Parasites

Chemistry – A European Journal, EarlyView.
Novel analogues of the kinetoplastid‐specific DNA base J unlock a new way to target parasite epigenetic regulation. Some compounds selectively inhibit Leishmania and Trypanosoma species without harming human cells, revealing a promising route toward innovative antiparasitic therapies.

Detection of Trypanosoma vivax in tissues of experimentally infected goats: what is the role of adipose tissue in the life cycle of this protozoon?

Revista Brasileira de Parasitologia Veterinária, 2021
Trypanosomiasis, caused by Trypanosoma vivax, is responsible for great economic losses among livestock in Africa and South America. During the life cycle of these parasites, they may present different morphological, metabolic and physiological ...

TNF‐α partially modulates the endothelial dysfunction during the acute phase of Trypanosoma cruzi infection

British Journal of Pharmacology, EarlyView.
Background and Purpose Whereas the effects of Trypanosoma cruzi (T. cruzi) infection are well‐characterised in the heart, its impact on the vasculature has received little attention. In this study, we investigated the effects of acute and chronic T. cruzi infection on vascular responsiveness and the underlying mechanisms.
