Src kinase expression and activation has been shown as the primary pathway involved in the malignant osteosarcoma phenotype [ 34, 35].
Although SGLT1 plays a smaller role in renal glucose absorption than SGLT2, SGLT1 is the primary pathway involved in intestinal glucose and galactose absorption (2, 4, 5).
Our results suggest that decreased u-PA-dependent proteolysis is the primary pathway involved; however, additional u-PA-mediated mechanisms such as angiogenesis and cell signalling may also be beneficially altered.
Besides the primary pathway involves stem-to-loop processing [ 20, 21], the second pathway involves loop-to-base processing in which the sequence and structure beyond the miRNA-miRNA* site are necessary and used by the cleavage pathway components to excise the mature sequence(s) [ 22, 23].
Hypoxia-inducible factor is considered to be one of the primary regulatory pathways involved in hypoxia tolerance (Wang and Semenza 1993).
The C. ljungdahlii iHN637 reconstruction accounts for 637 genes, 698 metabolites, 690 intracellular reactions, and 95 exchange reactions that capture the primary metabolic pathways involved in synthesis gas fermentation [ 21].
At least 3 primary molecular pathways involved in the progression of CRC have been identified, including the prevalent chromosomal instability (CIN) pathway (identified in up to 80% of cases), the CpG island methylator phenotype (CIMP) pathway, and microsatellite instability (MSI), resulting from the DNA mismatch repair (MMR) gene [ 18].
The primary signalling pathway involved in pro-inflammatory responses to a genetically related species, S. pneumonia, (> 99% homology by 16S rRNA to S. oralis, (Johnston et al., 2010)), involves TLR2 activation (Dessing et al., 2008; Beisswenger et al., 2009).
We then went on to investigate the effect of C4BP/sCD154 complex on the major signalling pathways involved in primary cholangiocyte survival, NFkB (RelA), AP-1 (cJun/cFos) and STAT 3. We have previously shown that activation of cholangiocyte CD40 leads to transient RelA expression and sustained cJun/cFos and STAT 3 expression [3], [4] resulting in apoptosis.
This database provides information regarding the metabolic pathways involved in primary and secondary metabolism with associated compounds, enzymes and genes [ 14].
