Retinoic acid represses CYP7A1 expression in human hepatocytes and HepG2 cells by FXR/RXR-dependent and independent mechanisms

open access: yesJournal of Lipid Research, 2010
Cholesterol 7α-hydroxylase (CYP7A1) plays a key role in maintaining lipid and bile salt homeostasis as it is the rate-limiting enzyme converting cholesterol to bile acids. Deficiency of CYP7A1 leads to hyperlipidemia in man and mouse.

Surprising features of nuclear receptor interaction networks revealed by live-cell single-molecule imaging

open access: yeseLife
Type II nuclear receptors (T2NRs) require heterodimerization with a common partner, the retinoid X receptor (RXR), to bind cognate DNA recognition sites in chromatin. Based on previous biochemical and overexpression studies, binding of T2NRs to chromatin

Vitamin D Represses Retinoic Acid-Dependent Transactivation of the Retinoic Acid Receptor-ß2 Promoter: The AF-2 Domain of the Vitamin D Receptor Is Required for Transrepression [PDF]

open access: yes, 1999
10 pages, 8 figures.Retinoic acid (RA)-dependent activation of the RA receptor ß2 (RARß2) gene in embryonal carcinoma cells is mediated by binding of retinoid receptor heterodimers (RAR/RXR) to a RA response element (RARE) located closely to the TATA box.
