Promotion of homology-directed DNA repair by polyamines
Nature Communications, 2019 The maintenance polyamines homeostasis is important for cell growth, and several cancers harbor elevated levels of polyamines that may contribute to sustained proliferative potential. Here the authors demonstrate that polyamines participate in DNA double-

Physiological importance of polyamines [PDF]
, 2017 Polyamines are polycationic molecules that contain two or more amino groups (-NH3 +) and are present in all eukaryotic and prokaryotic cells. Polyamines are synthesized from arginine, ornithine, and proline, and from methionine as the methyl-group donor.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Polyamines and carcinogenesis [PDF]
, 2012 SUMMARY The naturally occurring polyamines, spermine, spermidine and the diamine putrescine are widespread in nature. They have been implicated in growth and differentiation processes.

Practical Synthesis of Polyamine Succinamides and Branched Polyamines
ChemistryOpen, 2022 AbstractAntibiotic resistance is now a growing threat to human health, further exacerbated by the lack of new antibiotics. We describe the practical synthesis of a series of substituted polyamine succinamides and branched polyamines that are potential new antibiotics against both Gram‐positive and Gram‐negative bacteria, including MRSA and Pseudomonas ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Molecular Adsorbing Host•Guest (MAHG) Crystals: A New Paradigm for Porous Materials?
Advanced Functional Materials, EarlyView.Networking! Introduction of guest molecules in macrocycles before crystallization profoundly influences the material obtained in terms of structure and function. Beside simplicity and porous space improvement, this approach is endowed with a huge potential given the myriad of potential guest molecules that can be used to tune this burgeoning class of ...

Synthetic polyamines as potential amine oxidases inhibitors: a preliminary study. [PDF]
, 2010 Natural polyamines, such as putrescine and spermine, are widely distributed in living organism and they are involved in the regulation of many cellular functions (from cell growth, to apoptosis and cell death).
