Improvement of plant regeneration efficiency using polyamines for double haploid production in wheat (Triticum aestivum)

The Indian Journal of Agricultural Sciences, 2022
Polyamines are low molecular weight nitrogen containing compounds present in all living organisms. These are considered to be a new class of plant hormones, and play a positive role in plant growth and developmental processes including cell division, in

Growth regulatory effects of cyclic AMP and polyamine depletion are dissociable in cultured mouse lymphoma cells. [PDF]

, 1983
Treatment of mouse lymphoma S49 cells with D,L-alpha-difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase, depleted cellular polyamine levels and stopped cell growth. The cells were arrested predominantly in G1.

Stimuli‐Responsive Silsesquioxane Nanozymes for Organocatalysis in Water and Prodrug Activation in Cells

Angewandte Chemie, EarlyView.
Amino‐bearing silsesquioxanes are water‐stable nanozymes that exhibit aggregation‐ and disaggregation‐dependent catalysis and can be applied to intracellular prodrug activation for cancer therapy. ABSTRACT Synthetic nanozymes have emerged as promising alternatives to natural enzymes for catalytic and therapeutic applications, yet their limited ...

Effects of post-translational modifications catalysed by pollen transglutaminase on the functional properties of microtubules and actin filaments [PDF]

, 2009
TGases (transglutaminases) are a class of calcium-dependent enzymes that catalyse the interactions between acyl acceptor glutamyl residues and amine donors, potentially making crosslinks between proteins.
