Retinoid X receptor: the forgotten partner in regulating lipid metabolism?

Retinoid X Receptor Agonists Impair

MicroRNAs regulating lipid metabolism in atherogenesis.

MicroRNAs have emerged as important post-transcriptional regulators of lipid metabolism, and represent a new class of targets for therapeutic intervention. Recently, microRNA-33a and b (miR-33a/b) were discovered as key regulators of metabolic programs including cholesterol and fatty acid homeostasis. These intronic microRNAs are embedded in the sterol response element binding protein genes, S...

Retinoid X receptor-antagonistic diazepinylbenzoic acids.

Several dibenzodiazepine derivatives were identified as novel retinoid X receptor (RXR) antagonists on the basis of inhibitory activity on retinoid-induced cell differentiation of human promyelocytic leukemia cells HL-60 and transactivation assay using retinoic acid receptors (RARs) and RXRs in COS-1 cells. 4-(5H-2,3-(2,5-Dimethyl-2,5-hexano)-5-n- propyldibenzo[b,e][1,4]diazepin-11-yl)benzoic a...

Effect of Hyperoxia on Retinoid Metabolism and Retinoid Receptor Expression in the Lungs of Newborn Mice

BACKGROUND Preterm newborns that receive oxygen therapy often develop bronchopulmonary dysplasia (BPD), which is abnormal lung development characterized by impaired alveologenesis. Oxygen-mediated injury is thought to disrupt normal lung growth and development. However, the mechanism of hyperoxia-induced BPD has not been extensively investigated. We established a neonatal mouse model to investi...

The Function of Retinoid X Receptor α in Cancer Cells

The retinoid X receptor (RXR) is a member of the steroid/thyroid hormone superfamily of nuclear receptors (NRs) which are transcription factors that are essential in embryonic development, maintenance of differentiated phenotypes, metabolism and cell death. This review is to provide an overview of the mechanism of RXRα and RXRα signaling pathways involving RXR/TR3, RAR/RXR, PPAR/RXR, VDR/RXR, L...
