Moreover, several of the most abundant pathways including ammonium transport, Rubisco shunt, NADH to cytochrome electron transfer, pyruvate fermentation, denitrification, Calvin-Benson-Bassham cycle, cysteine biosynthesis I and arginine biosynthesis III exhibited depth-dependent trends in gene expression (Additional file 1: Figure S8).
Glutamine is the most abundant amino acid in the body, being used in several pathways, including those of the nucleotide synthesis, oxidation in the Krebs cycle to produce ATP, and as a lipogenic and gluconeogenic precursor [ 13].
The insulin-signaling pathway activates a powerful gene regulator that controls many genetic pathways, including some that govern metabolism.
Three distinct pathways including succinate pathway, acrylate pathway, and propanodiol pathway, can generate propionic acid (Reichardt et al., 2014).
IGFBP3 is the most abundant IGF-binding protein in the circulation, where it controls the half-life and bioavailability of IGF1 for signal transduction through the IGF1 Receptor (IGF1R), which leads to the activation of growth promoting pathways, including the Ras/Raf/MAP kinase and the phosphotidylinositol-3 kinase pathways (Renehan et al, 2004; Papatsoris et al, 2005).
These signaling pathways include RAF MAPP kinase pathway), PI3K (AKT/MTOR pathway), ERK, RLIP and RALGDS as seen in Fig. 1.
In ASs, these pathways included riboflavin metabolism.
In OLpres, these pathways included the cytochrome P450 pathway.
Conversely, transcripts of the genes whose expression is shown to be suppressed by TGF-β/phospho-Smad pathway, including transcription factors c-Myc and KLF4, were more abundant in α6+/MHCI+ cells.
Several positive-acting ligands for this pathway, including Wnt3, Wnt3a, Wnt7b, and Wnt5a, are significantly overexpressed in tumor tissue, and mRNA for Wnt3 is about 5-fold more abundant in transgenic mammary tissue than in non-transgenic mammary tissue.
As compared to previous chloroplast proteome studies, the current study significantly increased coverage of lower abundant pathways.
