A review is presented of the recent developments in the metabolism andfunction of
polyamines in plants. Polyamines appear to be involved in a widerange of plant processes …

Introduction Polyamines (putrescine, spermidine and spermine) are ubiquitous polycationic
metabolites in prokaryotic and eukaryotic cells. Their roles in the regulation of major …

We have reviewed studies on calcium-induced fusion of lipid bilayer membranes and the
role of synexin and other calcium-binding proteins (annexins) in membrane fusion. We have …

The polyamines spermidine (1, 8-diamino-4-azaoctane, 2) and spermine (1, 12-diamino-4, 9-
diazadodecane, 3), as well as the precursor molecule putrescine (1, 4-diaminobutane …

Polyamines appear to inhibit peroxidation of vesicles containing acidic phospholipids. A
correlation exists between polyamine binding to phospholipid vesicles and its protective …

Fusion of Negatively Charged abstract: Polyhistidine facilitates the fusion of negatively
charged liposomes prepared by sonication. Liposome fusion was demonstrated by (a) …

The cystic fibrosis transmembrane conductance regulator (CFTR) is the secretory chloride
channel in epithelial tissues that has a central role in cystic fibrosis (CF) lung and …

We describe rapid massive endocytosis (MEND) of> 50% of the plasmalemma in baby
hamster kidney (BHK) and HEK293 cells in response to large Ca transients. Constitutively …

Membrane fusion is an important biological process that is observed in a wide variety of intra-
and intercellular events. Little is known about its molecular mechanisms and few of the …

This investigation shows whether polyamines and ornithine decarboxylase have a role in
duodenal mucosal repair following stress-induced microscopic damage. Rats were fasted …
