Retinoid Inhibits Nrf2 Signaling Pathway through Retinoic Acid Receptor Alpha

The N-terminal region contains two domains (A / B) called AF1, which are the least conserved domains, are of great length and exhibit ligand-independent transactivating activity. So far, the three-dimensional structure of the A / B domain has not been predicted. (9) The central region -C has a DNA binding domain (DBD), which is said to be the most conserved region and has similarity in its structure. DBD contains important short motifs called P boxes, which are involved in direct interaction of DNA and detection of DNA binding specificity.

Figure 1: Interaction between cellular stress signal and apoptotic pathway. Signaling through the death receptor pathway can be inhibited by downregulation of death receptor (DR) or epigenetic silencing or upregulation of cFLIP by hyperoxia. In the mitochondrial pathway, Bcl - 2 promotes the promotion of the pro - oxidative environment for survival, while the reduced form of cytochrome c inhibits its activity and initiates caspase activation by apoptotic bodies. At the post-mitochondrial level, translation of XIAP and cIAP1 is maintained by IRES-dependent mechanisms even under cellular stress conditions. For details, please refer to the text.

Membrane related transport system, ion channel, enzyme activity, receptor function and various signaling pathways Recently, gene expression levels of specific transcription factors, peroxisome proliferator activated receptor (PPAR) and retinoic acid receptor It is reported that it plays a role in determining the roles and thereby the ability to better identify these increases the interest in the role of nutrients Lipid metabolism, energy distribution, insulin sensitivity, adipocyte development and neural function Regulation (Innis, 1991; Lauritzen et al., 2001)

Retinoic acid receptors are another subset of nuclear receptors. They can be activated by endocrine synthetic ligands diffusing intracellularly by ligands such as retinol synthetic ligands carried intracellularly through the blood stream or fully intracellularly synthesized ligands such as prostaglandins. These receptors are located in the nucleus without HSP. If the ligands do not bind to them, they inhibit their genes by binding to their specific DNA sequences, and vice versa.
