These changes probably resulted in blockade of direct development and deep restructuring of metabolic pathways indicated by differential expression of genes involved in cell cycle regulation, metabolism, detoxification, redox balance, protection against oxidative stress, cuticle formation and synthesis of larval storage proteins.
These microbial effects were associated with modulation of a range of host metabolic pathways indicated by changes in lipid profiles, gluconeogenesis, and amino acid and methylamine metabolism, and were associated with fermentation of carbohydrates by different bacterial strains.
2) Down-regulation of various metabolic pathways, which indicates a significant metabolic alteration in ccRCC compared to normal renal cells.
Energy may also be produced by other metabolic pathways as indicated by the abundance of transcripts encoding enzymes involved in glycolysis (not shown on the schema).
Furthermore, each species had specific genes and transporters required for various metabolic pathways, which indicates that they have different requirements for transporting various ions, nutrients, and other metabolites across their outer membranes.
Gene expression levels of the metabolic pathways was indicated by the line width, which was determined from the log 2 values of the read count of KEGG annotated proteins.
The affinities of the two metabolic pathways are indicated by the K m analogs, designated X50,1 and X50,2, respectively, in Table 2. [Note that factors other than K m can influence X50,1 and X50,2; see, e.g., Hildebrand et al. (1981).] The estimated values of X50,1 and X50,2 were 301 ppm and 0.594 ppm, respectively, indicating a 507-fold difference in enzyme affinities.
Metabolic pathway analysis indicated that these 120 proteins were involved in 12 biological processes unique to pathogens and 49 biological processes that were common in both host and pathogen.
Furthermore, the regions on the ordering associated to ECM-receptor represent functionally related gene sets that are not representing some specific GO term or metabolic pathway, as indicated by a functional annotation analysis using David Functional Annotation Tools [ 24, 35].
Fig. 2A shows the metabolic snapshots of the glycolysis pathway indicating enhanced glycolytic activity as an initial response to kainite treatment; most of the glycolytic intermediates were significantly decreased 30 min after kainate administration (blue-colored graphs), suggesting the occurrence of acute glycolysis.
