1. 1. Effects of polyamine pool manipulation on genes expressed during the cell cycle

   Författare :Pia Berntsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal physiology; cyclin A; ODC; MCF-7; mitotic shake off; DENSPM; CHO; cDNA microarray; cell cycle; spermine; Djurfysiologi; AdoMetDC; 2D gel electrophoresis; polyamines; spermidine; putrescine;

   Sammanfattning : The polyamines - putrescine, spermidine and spermine - are polycations found within cells. They have been shown to be essential for optimal cell proliferation and cell survival. Cells maintain their polyamine levels in a well-regulated system involving biosynthesis, catabolism and uptake/excretion. LÄS MER

3. 2. Carbonate Ions and Gastric Cancer

   Författare :Roy Ehrnström; Malmö Patologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; ODC; COX-2; inflammation; Wistar rats; duodenogastric reflux; Medicin människa och djur ; proliferation; gastrojejunostomy; carbonate ions; Experimental gastric cancer;

   Sammanfattning : Nearly one million new cases of gastric cancer are diagnosed annually throughout the world. Even though the incidence has fallen dramatically in recent decades, this disease is still the second leading cause of cancer death in a global perspective. LÄS MER

5. 4. On the Regulation of Ornithine Decarboxylase

   Författare :Eva Lövkvist Wallström; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; Crithidia fasciculata.; polyamines; Ornithine decarboxylase; translational control; osmolarity; untranslated region; COS cells; CHO cells; transfection; protein turnover; PEST region;

   Sammanfattning : The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. LÄS MER

7. 5. A Study on Trypanosomal Polyamine Biosynthetic Enzymes

   Författare :Sima Nasizadeh; Biogena aminer; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell cycle; protein turnover; trypanosomatids; polyamines; Ornithine decarboxylase; S-adenosylmethione decarboxylase; Parasitology human and animal ; Parasitologi människa och djur ;

   Sammanfattning : The polyamines, putrescine, spermidine, and spermine, are essential for all forms of life. The polyamine biosynthetic pathway has been shown to be a potential target for drugs against various trypanosomal parasitic diseases. LÄS MER
