Figure 9.3. Model for the action of humic substances (HS) on plasma membrane-bound targets of a root hair cell. Besides the well-known effects on plasma membrane H+-ATPase (P) and carriers (C) of mineral nutrients, the envisaged alteration of membrane lipid environment and the possible interaction with an hypothetical membrane receptor (R) for humic molecules which allows transduction of the signal for induction and expression of genes involved in nutrient uptake and root hair development are also presented.

Although the human genome project and subsequent efforts have sparked interest in the effects of SNPs on common diseases, the intersection of genomics and nutrition is relatively unexplored. To this end, nutritional genomics has emerged as a discipline that seeks to provide information on gene-nutrient interactions (and vice... [Pg.155]

Figure 29-6. Gene transcription is regulated by retinoic acid.Ah-Zrwm-retinoic acid and 9-cA-retinoic acid are ligands for retinoic acid receptors (RARs) and retinoid X receptors (RXRs), respectively. The RXRs can form heterodimers with RARs and with the thyroid hormone receptors (TRs), the vitamin D receptor (VDR), and the peroxisome proliferator-activated receptors (PPARs) and a number of other hormone- and nutrient-responsive transcription factors to moderate gene transcription. Because of the ability of RXR to form heterodimers with other nuclear receptors, vitamin A has abroad effect on many hormonally and nutrient-responsive genes. Figure 29-6.

It quantifies the effect of a perturbation of an external effector A (e.g. the concentration of a nutrient) on the flux J via enzyme i. If A effects different enzymes, perturbations of A can effect J via different routes and the regulatory strengths quantify the relative importance of each of these regulatory routes. A different, but related approach was taken by Westerhoff and Ter Kuile (ter Kuile and Westerhoff 2001). They developed Regulation Analysis, a theory that quantifies the relative importance of flux regulation via metabolism and via gene expression (Section 2.5). [Pg.248]
