Structure-Activity Investigations Of Polyamine-Anthracene Conjugates And Their Uptake Via The Polyamine Transporter

, 2007
A series of polyamine conjugates were synthesized and evaluated for their ability to target the polyamine transporter (PAT) in two Chinese hamster ovary (CHO) cell lines (PAT-active CHO and PAT-inactive CHOMG).

Proteo‐transcriptomic insights into the venom composition of the ectoparasitoid Eupelmus urozonus

Pest Management Science, EarlyView.
Integrated venom‐gland transcriptomics and venom proteomics of Eupelmus urozonus identified 316 venom proteins, including 75 secreted candidates, revealing diverse hydrolases, proteases/inhibitors and many uncharacterized effectors. Abstract BACKGROUND Ectoparasitoid venoms are ‘cocktails’ of bioactive molecules injected during oviposition to paralyze ...

Polyamine-mediated ferroptosis amplification acts as a targetable vulnerability in cancer

Nature Communications
Targeting ferroptosis, an iron-dependent form of regulated cell death triggered by the lethal overload of lipid peroxides, in cancer therapy is impeded by our limited understanding of the intersection of tumour’s metabolic feature and ferroptosis ...

Polyamine Metabolism in Brain Health and Disease

Neuropharmacology and Therapy
Polyamines, primarily spermidine and spermine, are small polycationic molecules essential for cell growth, signaling, and survival. Through electrostatic interactions with nucleic acids, lipids, and proteins, they regulate gene expression, organelle ...

Catechins and Their Effect on the Gut Microbiome in Health and Cancer

Phytotherapy Research, EarlyView.
ABSTRACT Catechins are a group of flavonoids found primarily in green tea, fruits, and berries; they play a significant role in the modulation of the gut microbiota, thereby having an impact on gut health and cancer prevention. Owing to their low bioavailability, catechins are transformed by the gut microbiota into various bioactive metabolites such as

Fluorescence Sensing of Anions Like Adenosine 5ʹ‐Triphosphate With pH‐Gated Porous Dye‐Loaded Cerasomes

Small, EarlyView.
The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

Exposure to Structurally Related Organophosphate Esters Elicits Distinct Metabolomic Perturbations in Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Organophosphate esters (OPEs) are found ubiquitously in the environment and exposure to these chemicals has induced behavioral, developmental, and morphological impairments in several model organisms. Yet there is still a lack of understanding of how sub‐lethal exposure disrupts organism function at the molecular‐level, especially for Daphnia ...
