Agmatine, a divalent diamine with two positive charges at physiological pH, is transported into the matrix of liver mitochondria by an energy-dependent mechanism, the driving force of which is the electrical membrane potential. Its binding to mitocho

The charge of the agmatine analogues AO-Agm [N-(3-aminooxypropyl)guanidine], GAPA [N-(3-aminopropoxy)guanidine] and NGPG [N-(3-guanidinopropoxy)guanidine] is deficient as compared with that of agmatine and they are thus able to inhibit agmatine trans

Background/Aims : Previous experiments have shown that agmatine, the product of arginine decarboxylase, is transported in competition with putrescine into quiescent rat hepatocytes, where it promotes several effects, including marked decrease of intr

Cytosolic spermidine/spermine acetyltransferase (SSAT) catalyzes the acetylation of the N 1 -propylamino groups of spermine and spermidine. The enzyme has a very short half-life and is rapidly induced by various stimuli. Once acetylated, these polyam

Agmatine has been proposed as the physiological ligand for the imidazoline receptors. It is not known whether it is also involved in the homoeostasis of intracellular polyamine content. To show whether this is the case, we have studied the effect of

Rat hepatocytes in culture take up [14C]-agmatine by both a high-affinity transport system [KM = 0.03 mM; Vmax = 30 pmol x min x (mg protein)-1] and a low-affinity system. The high-affinity system also transports putrescine, but not cationic amino ac

A series of diamines with the general structure NH2(CH2) x NH2, x=2–12, was tested for their potential effects on cell proliferation of cultured rat C6 glioma cells in comparison to natural polyamines. Long chain diamines reduced cell number after

Uptake of polyamines has been investigated extensively in many cells, but not in placenta, where the polyamine– polyamine oxidase system is supposed to have an immunoregulatory function in pregnancy. Due to the importance of the transfer in this ti
