Properties and physiological function of the polyamine transport system

, 1989
Polyamine transport was examined in Chinese hamster ovary (CHO) cells because of the unique potential these cells hold for utilizing genetic approaches to study the mechanisms of polyamine transport, its regulation, and its function.

Urinary and Faecal Amino‐Acids as Biomarkers for Colorectal Neoplasia in Lynch Syndrome—A Prospective Longitudinal Study

International Journal of Cancer, EarlyView.
ABSTRACT In Lynch syndrome, colonoscopy surveillance for colorectal cancer (CRC) is burdensome and post‐colonoscopy CRCs still occur. Unlike the faecal immunochemical test (FIT), gut metabolomic alterations including amino‐acids have shown potential as non‐invasive biomarkers for detecting both advanced and non‐advanced sporadic colorectal neoplasia ...

Polyamine Depletion with Two Different Polyamine Analogues Causes DNA Damage in Human Breast Cancer Cell Lines.

, 2008
It is well known that the positively charged polyamines have a DNA-stabilizing function and that polyamine depletion alters chromatin function. We have previously shown that polyamine depletion causes an S phase prolongation, and others have shown that ...

Effects of Glyphosate and Glyphosate‐Based Herbicides on the Mammalian Gut Microbiome: A Critical Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Glyphosate has long been considered to pose negligible direct risk to mammals on the grounds that its molecular target, 5‐enolpyruvylshikimate‐3‐phosphate synthase (EPSPS), of the shikimate pathway, is absent from animal cells. This rationale is inaccurate as a complete toxicological argument, because the shikimate pathway is present in some ...

Beyond a dual role: how Purpureocillium lilacinum reprograms citrus metabolism for integrated biocontrol and growth promotion

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Plants harbor complex microbial communities that are fundamental to their health and productivity. Among them, endophytic fungi such as Purpureocillium lilacinum establish mutualistic associations, offering dual benefits as plant growth promoters and biocontrol agents.

The Oncologic Ambivalence of Longevity Interventions in Photoaged Skin

JEADV Clinical Practice, EarlyView.
This graphical abstract presents a stage‐dependent framework for longevity interventions in photoaged skin. UV exposure drives progression from photodamage to field cancerization and skin cancer. Systemic interventions may modulate stress‐response pathways throughout the body, whereas energy‐based procedures generate spatially confined responses ...

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

AI‐Driven Rational Design of Nanotherapeutics for Pancreatic Ductal Adenocarcinoma

Medicinal Research Reviews, EarlyView.
ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) remains a formidable malignancy characterized by late diagnosis, high recurrence rates, and pronounced chemoresistance. While nanoparticle‐based drug delivery systems (NDDS) offer theoretical advantages over conventional therapies, their clinical translation in PDAC has been severely limited.
