Distribution of peroxidase activity and polyamine pattern of Heliotropium europeum in potassium deficiency conditions
(INDERSCIENCE ENTERPRISES LTD, WORLD TRADE CENTER BLDG, 29 ROUTE DE PRE-BOIS, CASE POSTALE 896, CH-1215 GENEVA, SWITZERLAND, 2007)Polyamines, especially putrescine, are reported to increase in higher plants in response to various stressors, in particular mineral deficiency, low pH and different atmospheric pollutants. Peroxidases are another stress ... -
Effects of polyamines and polyamine biosynthetic inhibitors on mitotic activity of Allium cepa root tips
(AKADEMIAI KIADO, PRIELLE K U 19, H-1117 BUDAPEST, HUNGARY, 2008-03)The genotoxic and cytotoxic effects of exogenous polyamines (PAs), putrescine ( Put), spermidine (Spd), spermine (Spm) and PA biosynthetic inhibitors, alpha-difluoromethylornithine ( DFMO), cyclohexilamine (CHA), methylglioxal ... -
Inhibition Of Ornithine Decarboxylase Alters The Roscovitine-Induced Mitochondrial-Mediated Apoptosis In MCF-7 Breast Cancer Cells
(Spandidos Publ Ltd, Pob 18179, Athens, 116 10, Greece, 2012-05)Polyamines (PAs) are small aliphatic amines that play a major role in multicellular functions. The PA levels are controlled by ornithine decarboxylase (ODC), the rate limiting enzyme of PA biosynthesis. alpha-difluoromet ... -
Inhibition of Polyamine Oxidase Prevented Cyclin-Dependent Kinase Inhibitor-Induced Apoptosis in HCT 116 Colon Carcinoma Cells
(Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2013-12)Roscovitine and purvalanol are novel cyclin-dependent kinase (CDK) inhibitors that prevent cell proliferation and induce apoptotic cell death in various cancer cell lines. Although a number of studies have demonstrated the ... -
Nitric Oxide Signalling In Plants
(Springer, 233 Spring St, New York, Ny 10013 Usa, 2009-06)Nitric oxide (NO) is an important molecule that acts in many tissues to regulate a diverse range of physiological processes. It is becoming apparent that NO is a ubiquitous signal in plants. Since the discovery of NO ... -
Polyamine Depletion Enhances The Roscovitine-Induced Apoptosis Through The Activation Of Mitochondria In HCT116 Colon Carcinoma Cells
(Springer, 233 Spring St, New York, Ny 10013 Usa, 2012-02)Small molecule inhibitors of cyclin-dependent kinases (CDKs) show high therapeutic potential in various cancer types which are characterized by the accumulation of transformed cells due to impaired apoptotic machinery. ... -
Polyamines in tea processing
(TAYLOR & FRANCIS LTD, 4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND, 2007)The distribution of dietary polyamines, putrescine, spermidine and spermine, was determined during processing of Camellia sinensis. Black tea manufacture is carried by a series of processes on fresh tea leaves involving ... -
Serum Adipocytokine Levels in Prostate Cancer Patients
(Karger, Allschwilerstrasse 10, Ch-4009 Basel, Switzerland, 2009)Introduction: We estimated the circulating levels of adipocytokines such as adiponectin and leptin in nonobese nondiabetic prostate cancer (PCa) patients and compared the results with controls and benign prostate hyperplasia ... -
Silencing Of The Polyamine Catabolic Key Enzyme SSAT Prevents CDK Inhibitor-Induced Apoptosis In Caco-2 Colon Cancer Cells
(Spandidos Publ Ltd, Pob 18179, Athens, 116 10, Greece, 2012-04)Roscovitine and purvalanol are purine derivative cyclin-dependent kinase (CDK) inhibitors that induce apoptosis in various types of cancer cells. However, their impact on the apoptotic cell death mechanism requires further ...
