Exploring polyamines: Functions in embryo/fetal development
Animal Nutrition, 2017 Polyamines such as putrescine, spermidine, spermine and agmatine are aliphatic polycationic compounds present in all living cells, and are derived from amino acids, intestinal bacteria, exfoliated enterocytes and supported from diet.

Transcriptomic Profiling of SLC and ABC Transporters in the Human Term Placenta
Clinical Pharmacology &Therapeutics, EarlyView.Solute carriers (SLC) and ATP‐binding cassette (ABC) transporters are essential for placental solute exchange and fetal protection, yet their transcriptomic profiles in the human placenta remain poorly characterized. Although fetal sex influences placental development and function, its impact on transporter expression is unclear.

Intestinal Epithelial Memory: From Inflammatory Imprinting to Metabolite‐Shaped Immune Tolerance
Barrier Immunity, EarlyView.ABSTRACT Intestinal epithelial cells are rapidly renewing barrier cells that maintain compartmentalization between the luminal environment and the mucosal immune system through epithelial transport, antimicrobial defense, secretory programs, and cytokine‐mediated communication.

Polyamines alter intestinal glucose transport
, 1995 Polyamines are required for the growth of all eukaryotic cells. Enterocytes respond to luminal nutrients with large increases in polyamine synthesis, even though they are mature, nonproliferating cells.

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.
