Alzheimer's disease (AD) is characterized pathologically by the presence of amyloid plaques and neurofibrillary tangles.  The amyloid hypothesis contends that the abnormal accumulation of Aβ, the principal component of amyloid plaques, plays an essential role in initiating the disease....

Identifying the receptor subtype selectivity of retinoid X and retinoic acid receptors via quantum mechanics.

FEBS open bio

Understanding and identifying the receptor subtype selectivity of a ligand is an important issue in the field of drug discovery. Using a combination of classical molecular mechanics and quantum mechanical calculations, this report assesses the receptor subtype selectivity for...

EPA/DHA and Vitamin A Supplementation Improves Spatial Memory and Alleviates the Age-related Decrease in Hippocampal RXRγ and Kinase Expression in Rats.

Frontiers in aging neuroscience

Létondor A, Buaud B, Vaysse C, Richard E, Layé S, Pallet V, Alfos S.
PMID: 27242514
Front Aging Neurosci. 2016 May 09;8:103. doi: 10.3389/fnagi.2016.00103. eCollection 2016.

Studies suggest that eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and vitamin A are critical to delay aged-related cognitive decline. These nutrients regulate gene expression in the brain by binding to nuclear receptors such as the retinoid X receptors (RXRs)...

A Novel Method for a Stereoselective Synthesis of Trisubstituted Olefin Using Tricarbonyliron Complex: A Highly Stereoselective Synthesis of (all-E)- and (9Z)-Retinoic Acids.

The Journal of organic chemistry

Wada A, Hiraishi S, Takamura N, Date T, Aoe K, Ito M.
PMID: 11671757
J Org Chem. 1997 Jun 27;62(13):4343-4348. doi: 10.1021/jo961041+.

In order to establish the stereoselective synthesis of retinoic acids, which are ligand molecules of the retinoic acid receptors (RARs, all-E-isomer) and the retinoid X receptors (RXRs, 9Z-isomer), the reaction of beta-ionone-tricarbonyliron complex 7 with carbanions was investigated. Treatment...

The role of peroxisome proliferator-activated receptors in the development and physiology of gametes and preimplantation embryos.

PPAR research

Huang JC.
PMID: 18354728
PPAR Res. 2008;2008:732303. doi: 10.1155/2008/732303.

In several species, a family of nuclear receptors, the peroxisome proliferator-activated receptors (PPARs) composed of three isotypes, is expressed in somatic cells and germ cells of the ovary as well as the testis. Invalidation of these receptors in mice...

Polyunsaturated fatty acids: From diet to binding to ppars and other nuclear receptors.

Genes & nutrition

Bordoni A, Di Nunzio M, Danesi F, Biagi PL.
PMID: 18850203
Genes Nutr. 2006 Jun;1(2):95-106. doi: 10.1007/BF02829951.

Dietary polyunsaturated fatty acids (PUFAs) function not only by altering membrane lipid composition, cellular metabolism, signal transduction, but possess also effects on gene expression by regulating the activity/abundance of different nuclear transcription factors: peroxisome proliferator activated receptors, retinoid X...

Liver x receptor: a novel therapeutic target.

Indian journal of pharmaceutical sciences

Patel MB, Oza NA, Anand IS, Deshpande SS, Patel CN.
PMID: 20046702
Indian J Pharm Sci. 2008 Mar-Apr;70(2):135-44. doi: 10.4103/0250-474X.41445.

The liver X receptors alpha and beta are orphan nuclear receptors that are key regulators in maintaining cholesterol homeostasis. Originally they were found to play an important role in reverse cholesterol transport, a pathway for the removal of excess...

Regulation of retinoid and thyroid hormone action through homodimeric and heterodimeric receptors.

Trends in endocrinology and metabolism: TEM

Zhang XK, Kahl M.
PMID: 18407151

BACKGROUND: The Peroxisome proliferator-activated receptor gamma gene (PPARG), encodes a member of the peroxisome-activated receptor subfamily of nuclear receptors. PPARs form heterodimers with retinoid X receptors (RXRs) which regulate transcription of various genes. Three subtypes of PPARs are known:...

Retinoid X receptors (RXRs) belong to the nuclear receptor superfamily, and upon ligand activation, these receptors control gene transcription via either homodimerization with themselves or heterodimerization with the partner-nuclear receptor. The protective effects of RXRs and RXR agonists have...
