Retinoic acid is a potent regulator of growth plate chondrogenesis.
Vitamin A deficiency and excess both cause abnormalities in mammalian longitudinal bone growth. Because all-trans retinoic acid (RA) is synthesized from vitamin A, we hypothesized that RA regulates growth plate chondrogenesis. Consistent with this hypothesis, a single oral dose of RA reduced the height of the rat proximal tibial growth plate. To determine whether RA acts directly on growth plat...
متن کاملThe cellular retinoic acid binding protein II is a positive regulator of retinoic acid signaling in breast cancer cells.
The role of the cellular retinoic acid binding protein type II (CRABPII) in the retinoic acid (RA) signaling pathway is poorly understood. Northern blot analysis of 12 breast cell lines showed that CRABPII mRNA content correlated with growth inhibition by RA, suggesting that this binding protein enhances cellular response to RA. Ectopic CRABPII expression supported dose-dependent growth inhibit...
متن کاملCOUP-TFI is a potential regulator of retinoic acid-modulated development in Xenopus embryos
Isomers of retinoic acid are considered likely regulators of developmental pattern formation in vertebrate embryos. The orphan receptor COUP-TFI, which can alter cellular responses to retinoic acid in cultured cells, is expressed in distinct regions of the developing zebrafish and mouse anterior central nervous system. We asked if COUP-TFI can modulate retinoic acid signaling and anterior neura...
متن کاملPLZF is a negative regulator of retinoic acid receptor transcriptional activity
BACKGROUND: Retinoic acid receptors (RARs) are ligand-regulated transcription factors controlling cellular proliferation and differentiation. Receptor-interacting proteins such as corepressors and coactivators play a crucial role in specifying the overall transcriptional activity of the receptor in response to ligand treatment. Little is known however on how receptor activity is controlled by i...
متن کاملToll-like receptor 3 is a potent negative regulator of axonal growth in mammals.
Toll is a cell surface receptor with well described roles in the developmental patterning of invertebrates and innate immunity in adult Drosophila. Mammalian toll-like receptors represent a family of Toll orthologs that function in innate immunity by recognizing molecular motifs unique to pathogens or injured tissue. One member in this family of pattern recognition receptors, toll-like receptor...
