Retinoic Acid Isomers Facilitate Apolipoprotein E Production and Lipidation in Astrocytes through the Retinoid X Receptor/Retinoic Acid Receptor Pathway*

Journal of Biological Chemistry, 2014
Background: Apolipoprotein E (apoE) isoforms influence the risk for Alzheimer disease (AD). Results: All-trans-retinoic acid (RA), 9-cis-RA, and 13-cis-RA were identified as compounds that increase apoE expression and lipidation in astrocytes. Conclusion:

Retinoid receptors in ovarian cancer: expression and prognosis [PDF]

, 2017
Background: Ovarian cancer is frequently lethal despite aggressive multimodal therapy, and new therapies are therefore needed. Retinoids are potential candidate drugs: they prevent the development of ovarian carcinoma and enhance the efficacy of ...

NRF2 regulates HER1 signaling pathway to modulate the sensitivity of ovarian cancer cells to lapatinib and erlotinib [PDF]

, 2017
NF-E2-related factor 2 (NRF2) regulates the transcription of a battery of metabolic and cytoprotective genes. NRF2 and epidermal growth factor receptors (EGFRs/HERs) are regulators of cellular proliferation and determinants of cancer initiation and ...

A High‐Fidelity RNA‐Targeting Cas13X Downregulates Connexin43 in Macroglia: A Novel Neuroprotective Strategy for Glaucoma

Advanced Science, EarlyView.
This study highlights the role of connexin43 (Cx43) in mediating glia activation and neuroinflammation in glaucoma. Using Cx43 knockout mice, it is shown that macroglial cells‐derived Cx43 modulates microglial activation, proliferation, migration, and polarization.

Identification of novel NRF2-regulated genes by ChIP-Seq: influence on retinoid X receptor alpha

Nucleic Acids Research, 2012
Cellular oxidative and electrophilic stress triggers a protective response in mammals regulated by NRF2 (nuclear factor (erythroid-derived) 2-like; NFE2L2) binding to deoxyribonucleic acid-regulatory sequences near stress-responsive genes.

Vitamin D Receptor, Retinoid X Receptor, Ki-67, Survivin, and Ezrin Expression in Canine Osteosarcoma

Veterinary Medicine International, 2012
Canine osteosarcoma (OS) is an aggressive malignant bone tumor. Prognosis is primarily determined by clinical parameters. Vitamin D has been postulated as a novel therapeutic option for many malignancies.

Single‐Cell RNA Sequencing Reveals the Heterogeneity in Differentiation Trajectory and Tumor Microenvironment Leading to More Aggressive Phenotypes of Papillary Thyroid Cancer in Children and Young Adult Patients

Advanced Science, EarlyView.
scRNA sequencing reveals distinct tumor ecosystem features in CAYA‐PTC, marked by enriched CD4T_Tfh, CD8T_Tex cells, and rapid malignant thyrocyte differentiation (absent of mild‐state BRAF‐like population) toward invasive states. Prominent emCAF_LAMP5 populations interact with endothelial cells and thyrocytes facilitate angiogenesis and metastasis ...

Interaction of the peroxisome-proliferator-activated receptor and retinoid X receptor. [PDF]

Proceedings of the National Academy of Sciences, 1993
The rat peroxisome-proliferator-activated receptor (PPAR) was expressed in insect cells and was shown to bind to a cognate PPAR response element (PPRE) from the acyl-CoA oxidase gene. Upon purification, PPAR was no longer able to bind DNA, although binding could be restored by addition of insect cell extracts.

The anti-cancer effect of retinoic acid signaling in CRC occurs via decreased growth of ALDH+ colon cancer stem cells and increased differentiation of stem cells [PDF]

, 2018
Background: Tumorigenesis is driven by stem cell (SC) overpopulation. BecauseALDH is both a marker for SCs in many tissues and a key enzyme in retinoid acid (RA)signaling, we studied RA signaling in normal and malignant colonic SCs.Hypothesis: RA ...

Integrated Transcriptome and Metabolomics Analyses Show MYC as a Potential Therapeutic Target for Behçet's Uveitis

Advanced Science, EarlyView.
Integrated single‐cell transcriptomic and metabolomic analyses reveal that MYC‐driven glycolysis activates the PI3K‐AKT‐FOXO1 pathway, disrupting Th17/Treg balance and promoting uveitis. MYC inhibition restores immune homeostasis and alleviates disease symptoms.
