Anaerobic central metabolic pathways active during polyhydroxyalkanoate production in uncultured cluster 1Defluviicoccusenriched in activated sludge …
2009
A glycogen nonpolyphosphate-accumulating organism (GAO) enrichment culture dominated by the Alphaproteobacteria cluster 1 Defluviicoccus was investigated to determine the metabolic pathways involved in the anaerobic formation of polyhydroxyalkanoates, carbon storage polymers important for the proliferation of microorganisms in enhanced biological phosphorus removal processes. FISH-microautoradiography and post-FISH fluorescent chemical staining confirmed acetate assimilation as polyhydroxyalkanoates in cluster 1 Defluviicoccus under anaerobic conditions. Chemical inhibition of glycolysis using iodoacetate, and of isocitrate lyase by 3-nitropropionate and itaconate, indicated that carbon is …
Manipulation of glycolysis in malignant tumors: fantasy or therapy?
2009
After Warburg stated his hypothesis on tumor cell metabolism about 80 years ago, the field of carbohydrate metabolism of cancer cells and solid tumors is experiencing a boom for the past few years. Numerous studies have been focused on the characteristics of cancer metabolism and its accessibility to novel therapeutic interventions. Malignant transformation is associated with an increase in glycolytic flux, mainly caused by an upregulation of numerous glycolysis-related genes in the majority of human cancers. As a consequence of these alterations, tumor cells are producing lactate at higher levels compared to non-malignant tissue, even in the presence of oxygen, a phenomenon termed “aerobic…
