Testosterone as Diamine Oxidase Activity Regulator [PDF]

open access: yesBioDiscovery, 2017
Diamine oxidase (DAO) is a key enzyme of the metabolism of polyamines. Its activity was assayed in homogenate of male immature rat liver and kidney.  The androgens are important regulators of polyamines’ metabolism.

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABAA Receptors That Modulate Dorsal Root Ganglia Neuron Excitability

open access: yesGlia, Volume 74, Issue 9, September 2026.
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.

Chemoprevention of Colon Cancer by DFMO, Sulindac, and NO-Sulindac Administered Individually or in Combinations in F344 Rats

open access: yes, 2023
Non-steroidal anti-inflammatory drugs (NSAIDs) are promising colorectal cancer (CRC) chemopreventive drugs; however, to overcome NSAIDs’ associated side effects, there is a need to develop safer and efficacious approaches.

Novel Water‐Soluble, Heavy Atom‐Free Thioxanthene‐Fused Naphthalimide–Polyamine Phototheranostic Conjugates

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Water‐soluble, heavy‐atom‐free naphthalimide–polyamine conjugates were developed as novel phototheranostic agents. Conjugates 2 and 3 showed effective photocytotoxicity in MCF‐7 cells with negligible dark toxicity. Fluorescence imaging confirmed efficient cellular uptake.

The Dual Role of the Gut Microbiota in Cancer Chemoresistance

open access: yesMicrobiologyOpen, Volume 15, Issue 4, August 2026.
Comparison between Microbiota and Cancer therapy. ABSTRACT Chemoresistance is one of the primary reasons that cancer chemotherapy fails to deliver successful treatment outcomes and contributes to poor overall survival rates for patients with cancer. New research has begun to shed light on the effects of the gut microbiome (GM).

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Polyamine Depletion Attenuates Isoproterenol-Induced Hypertrophy and Endoplasmic Reticulum Stress in Cardiomyocytes

open access: yesCellular Physiology and Biochemistry, 2014
Background/Aim: Polyamines (putrescine, spermidine and spermine) play an essential role in cell growth, differentiation and apoptosis. Hypertrophy is accompanied by an increase in polyamine synthesis and endoplasmic reticulum stress (ERS) in ...
