Spermine binding to liver mitochondria

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1996
Non-equilibrium binding of spermine to mitochondrial membranes is studied in rat liver mitochondria by applying a new thermodynamic treatment of ligand-receptor interactions (Di Noto, V., Dalla Via, L., Toninello, A. and Vidali, M. (1996) Macromol. Theory Simul. 5, 165-181).

Metabolic reprogramming of efferocytosis in the tumour microenvironment: From apoptotic‐cell clearance to therapeutic targeting

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
This review systematically deconstructs the pathological efferocytic—metabolic axis in tumours, framing it as a three‐stage, self‐reinforcing cycle: from metabolite‐driven macrophage recruitment, through hijacked surface recognition, to post‐phagocytic metabolic reprogramming that locks in immunosuppression.

Lack of Influence of Spermine or Diet on Calf Spermine Oxidase Formation

Journal of Dairy Science, 1965
Abstract Studies were conducted to ascertain the changes in blood plasma spermine oxidase activity in the young dairy calf as the animal developed. Results show that there is a steady increase in plasma spermine oxidase activity up until 40-60 days of age with no further increase.

AMPA Receptors in NG2 Glia Differently Affect Signal Transduction in the Hippocampus and Cerebellum

Glia, Volume 74, Issue 2, February 2026.
Stronger expression of Ca2+ permeable AMPA receptors in cerebellar versus hippocampal NG2 glia. Different expression patterns of glial AMPA receptors and auxiliary subunits in both regions. Higher efficacy of neuron‐NG2 glia synapses in the cerebellum.

A Novel Human Cellular System for Studying Normal Aging and for Anti‐Aging Discovery

Aging Cell, Volume 25, Issue 2, February 2026.
This study introduces a human cellular aging model using placental trophoblasts (hTSC‐STBs) that mimics key aging features like senescence and genomic instability. It aligns with human tissue aging and responds to anti‐aging treatments, offering a scalable platform to screen potential therapies and bridge lab findings to clinical applications ...

Rapid detection of spermine by using a cost-effective carbon nanostructured aptasensor

Nano TransMed
Spermine is a polyamine that participates in ion channel regulation and cell proliferation. It is considered a biomarker for pancreatic cancer. In this study, a carbon nanostructure-based aptasensor has been developed to rapidly detect spermine in ...

Acrolein Promotes Retinal Inflammation Through Macrophage Chemotaxis by Inducing CCL2 Production From Müller Cells

The FASEB Journal, Volume 40, Issue 1, 15 January 2026.
Patients with proliferative diabetic retinopathy show elevated vitreous levels of the acrolein adduct FDP‐lys and CCL2. In rat Müller glial cells (TR‐MUL5), acrolein increases Ccl2 gene expression and CCL2 secretion and promotes macrophage migration.

Spermine Regulates Bone Homeostasis Through The Gut-Bone Axis

International Dental Journal
Aim or purpose: This study aims to explore the specific mechanism by which spermine, a metabolite highly expressed in the saliva of patients with MRONJ, regulates bone homeostasis through the gut-bone axis.

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

Advanced Functional Materials, Volume 36, Issue 1, 2 January 2026.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...
