Putrescine

01/01/1989 - "The combination of DFMO and 2-DG caused a significantly greater reduction in tumor weight and putrescine content compared with DFMO alone.(ABSTRACT TRUNCATED AT 250 WORDS)"
04/01/1997 - "Although these studies used [3H] putrescine at trace doses, it is estimated that infusion of higher doses of [3H] putrescine plus DFMO will selectively kill tumor cells."
07/01/2012 - "These results underscore the complexity of polyamine modulation of tumor development and emphasize the critical role of putrescine in tumor promotion. "
11/01/2010 - "The probiotics administration was correlated with a ten time diminution of fecal putrescine (cancer and bacterial disease marker) and a decrease of 60% mutagen fecal concentration, indicating the protective effect of the treatment. "
08/01/2008 - "During the process, a striking increase in maize polyamine biosynthesis, mainly free and conjugated putrescine occurred in the tumors induced by the fungus, and in the neighbor plant tissues. "

03/01/1970 - "Added putrescine permitted some of the cells of the first two mutants to divide sooner after amino acid starvation and thus eliminated synchrony. "
01/25/1988 - "Amino-acid starvation in polyamine-auxotrophic bacteria grown in the presence of putrescine provokes a marked inhibition of protein synthesis. "
04/15/1979 - "6. The ability to take up putrescine at low concentrations decreased during starvation of myxamoebae. "
01/01/1966 - "Cells grown on putrescine contained negligible amounts of acetyl putrescine, but readily formed acetyl putrescine when subjected to starvation."
09/01/2014 - "Putrescine-dependent expression of ygjG-lacZ was controlled by at least two sigma factors: rpoS under excess nitrogen conditions and rpoN under nitrogen-starvation conditions. "

01/01/1998 - "Putrescine-stimulated intracellular Ca2+ release for invasiveness of rat ascites hepatoma cells."
10/01/1992 - "Putrescine-dependent invasive capacity of rat ascites hepatoma cells."
01/01/1989 - "inoculation of 2 X 10(6) METH-A ascites tumor cells into BALB/c mice, ODC activity and putrescine concentration in the spleen were also elevated at about 1 d after inoculation. "
01/12/1982 - "Regulation of putrescine metabolism in Ehrlich ascites carcinoma cells exposed to hypotonic medium."
01/01/1978 - "The concentration of putrescine and spermidine in cell-free ascites fluid and serum was found to increase significantly with increasing tumour mass. "

09/01/1993 - "We report that the transgenic mice with grossly elevated putrescine in all brain regions analysed (cortex, striatum, hippocampus and cerebellum) showed a significantly elevated seizure threshold to chemical and electrical stimuli, and impaired performance in spatial learning and memory tests. "
09/01/1993 - "Elevated seizure threshold and impaired spatial learning in transgenic mice with putrescine overproduction in the brain."
01/04/1993 - "The increase in putrescine was clearly higher in PTZ kindling than in single convulsion. "
01/04/1993 - "The most marked increase was detected in putrescine 1-48 h after the intense seizures. "
09/18/1992 - "After PND 21, ODC activity and putrescine levels markedly increased 16 h after KA-induced seizure activity in hippocampus and piriform cortex. "

12/22/2006 - "This phenotype was cured by exogenous spermine but not by the other polyamines putrescine and spermidine, suggesting a strong link between spermine-deficiency and NaCl-hypersensitivity. "
01/12/2007 - "This phenotype was cured by spermine pretreatment but not by the other polyamines putrescine and spermidine, suggesting that drought-hypersensitivity exhibited by the mutant is due to spermine deficiency. "
12/01/2012 - "The intolerance of histamine and to some extent of other biogenic amines (such as cadaverine, putrescine, tyramine etc.) plays an important role in the differential diagnosis of the foodstuff intolerances and has to be strictly separated from immunologically mediated foodstuffs reactions (foodstuffs allergies, 2-5% of the population).
