Endogenous retinoic acid activity in principal cells and intercalated cells of mouse collecting duct system.

open access: yesPLoS ONE, 2011
BackgroundRetinoic acid is the bioactive derivative of vitamin A, which plays an indispensible role in kidney development by activating retinoic acid receptors.

Potential role of nuclear receptor ligand all-trans retinoic acids in the treatment of fungal keratitis [PDF]

open access: yesInternational Journal of Ophthalmology, 2015
Fungal keratitis (FK) is a worldwide visual impairment disease. This infectious fungus initiates the primary innate immune response and, later the adaptive immune response.

Exploitation of the vitamin A/retinoic acid axis depletes ALDH1-positive cancer stem cells and re-sensitises resistant non-small cell lung cancer cells to cisplatin

open access: yesTranslational Oncology, 2021
Despite advances in personalised medicine and the emerging role of immune checkpoints in directing treatment decisions in subsets of lung cancer patients, non-small cell lung cancer (NSCLC) remains the most common cause of cancer-related deaths worldwide.

In Vivo Imaging of Retinoic Acid Receptor Activity using a Sodium/Iodide Symporter and Luciferase Dual Imaging Reporter Gene

open access: yesMolecular Imaging, 2004
Retinoic acids are natural derivatives of vitamin A, and play important roles in modulating tumor cell growth by regulating differentiation, thus suggesting the potential use of these derivatives in cancer therapy and prevention.

Atypical Rearrangements in APL-Like Acute Myeloid Leukemias: Molecular Characterization and Prognosis

open access: yesFrontiers in Oncology, 2022
Acute promyelocytic leukemia (APL) accounts for 10–15% of newly diagnosed acute myeloid leukemias (AML) and is typically caused by the fusion of promyelocytic leukemia with retinoic acid receptor α (RARA) gene.

Neofunctionalization in vertebrates: the example of retinoic acid receptors. [PDF]

open access: yesPLoS Genetics, 2006
Understanding the role of gene duplications in establishing vertebrate innovations is one of the main challenges of Evo-Devo (evolution of development) studies.

Pathophysiological Role of Nucleic Acid-Sensing Pattern Recognition Receptors in Inflammatory Diseases

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Pattern recognition receptors (PRRs) play critical roles in recognizing pathogen-derived nucleic acids and inducing innate immune responses, such as inflammation and type I interferon production.

The quaternary architecture of RARβ–RXRα heterodimer facilitates domain–domain signal transmission

open access: yesNature Communications, 2017
Nuclear receptors (NR) are multidomain proteins, which makes their crystallization challenging. Here the authors present the crystal structure of the retinoic acid receptor β–retinoic X receptor α (RARβ–RXRα) heterodimer bound to DNA, ligands and ...

Anti-tumor effect in human lung cancer by a combination treatment of novel histone deacetylase inhibitors: SL142 or SL325 and retinoic acids. [PDF]

open access: yesPLoS ONE, 2010
Histone deacetylase (HDAC) inhibitors arrest cancer cell growth and cause apoptosis with low toxicity thereby constituting a promising treatment for cancer.

The conversion of β-carotene to vitamin A in adipocytes drives the anti-obesogenic effects of β-carotene in mice

open access: yesMolecular Metabolism, 2022
Objective: The β-carotene oxygenase 1 (BCO1) is the enzyme responsible for the cleavage of β-carotene to retinal, the first intermediate in vitamin A formation. Preclinical studies suggest that BCO1 expression is required for dietary β-carotene to affect
