Normal HC11 and ras-transformed mouse mammary cells are resistant to the antiproliferative effects of retinoic acid

Brazilian Journal of Medical and Biological Research, 2003
The objective of the present study was to determine the effects of retinoic acid on the growth of the mouse mammary cells HC11 and HC11ras, which are a model for in vitro breast cancer progression.

Retinoic acid upregulates ret and induces chain migration and population expansion in vagal neural crest cells to colonise the embryonic gut.

PLoS ONE, 2013
Vagal neural crest cells (VNCCs) arise in the hindbrain, and at (avian) embryonic day (E) 1.5 commence migration through paraxial tissues to reach the foregut as chains of cells 1-2 days later.

Retinoic acid receptors and retinoid X receptors: interactions with endogenous retinoic acids. [PDF]

Proceedings of the National Academy of Sciences, 1993
The binding of endogenous retinoids and stereoisomers of retinoic acid (RA) to the retinoid nuclear receptors, RA receptor (RARs) and retinoid X receptors (RXRs), was characterized using nucleosol preparations from transiently transfected COS-1 cells. Among several stereoisomers of RA tested, including 7-cis-, 9-cis-, 11-cis-, 13-cis-, and all-trans-RA,

Bifidobacterium Pseudolongum‐Derived Inosine Mitigates Polystyrene Nanoplastics‐Induced Hepatic Injury by Inhibiting the Polarization of M1 Macrophages

Advanced Science, EarlyView.
Probiotic B.p colonization elevated gut‐derived inosine level in the liver, while elevated inosine activated A2AR and subsequently blocked NPs‐induced polarization of M1 macrophages by repressing the miR155/SOCS1/NF‐κB pathway. This reduced the release of inflammatory cytokines and thereby, mitigated NPs‐induced hepatic injury.

The negative side of retinoic acid receptors [PDF]

Neurotoxicology and Teratology, 2011
This is a review of research that supports a hypothesis regarding early restriction of gene expression in the vertebrate embryo. We hypothesize that vertebrate retinoic acid receptors (RARs for several vertebrates but rars for zebrafish) are part of an embryonic, epigenetic switch whose default position, at the time of fertilization is "OFF".

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Administration of a selective retinoic acid receptor‐γ agonist improves neuromuscular strength in a rodent model of volumetric muscle loss

Journal of Experimental Orthopaedics, 2021
Purpose Volumetric muscle loss is a uniquely challenging pathology that results in irrecoverable functional deficits. Furthermore, a breakthrough drug or bioactive factor has yet to be established that adequately improves repair of these severe skeletal ...

Super‐Multiplexed Label‐Free Raman Imaging Uncovers Novel Testicular Metabolic Couplings for Residual Body and Spermatogonial Differentiation

Advanced Science, EarlyView.
Super‐multiplexed Label‐free Raman Imaging (SLRI) enables 2D/3D metabolic mapping of intact Drosophila testes. Moving beyond descriptive morphology, it establishes a multidimensional tool for tissue metabolic remodeling, and offers a generalizable platform for complex tissue analysis, with implications extending to development and disease. ABSTRACT The

RDH10, RALDH2, and CRABP2 are required components of PPARγ-directed ATRA synthesis and signaling in human dendritic cells

Journal of Lipid Research, 2013
All-trans retinoic acid (ATRA) has a key role in dendritic cells (DCs) and affects T cell subtype specification and gut homing. However, the identity of the permissive cell types and the required steps of conversion of vitamin A to biologically active ...
