Induction of retinoic acid receptor-beta by retinoic acid is cell specific.
Endocrinology, 1993The retinoic acid (RA) receptor-beta (RAR beta) gene is dramatically up-regulated by RA in F9 teratocarcinoma cells due to the presence of an RA-responsive element (RARE) in its promoter. Remarkably, however, RAR beta mRNA was essentially unaffected by RA in rat pituitary GH3 cells, even though the GH gene was induced by RA, and these cells express ...

Nuclear retinoic acid receptors: Conductors of the retinoic acid symphony during development
Molecular and Cellular Endocrinology, 2012The vitamin A derivative, retinoic acid (RA), is essential for embryonic development through the activation of cognate nuclear receptors, RARs, which work as ligand dependent regulators of transcription. In vitro studies revealed how RARs control gene expression at the molecular level and now it appears that it is fine-tuned by a phosphorylation code ...

Retinoic acid receptors, hematopoiesis and leukemogenesis
Current Opinion in Hematology, 2008All-trans retinoic acid therapy of acute promyelocytic leukemia represents the most successful example of differentiation-induction therapy in clinical oncology. However, acute promyelocytic leukemia represents only a small minority (10-15%) of the myeloid leukemias.

Modulation of limb bud chondrogenesis by retinoic acid and retinoic acid receptors.
The International journal of developmental biology, 1995An excess of retinoic acid (RA) in the mouse embryo in utero produces hypochondrogenesis and severe limb bone deformities. Since one of the RA receptors--RAR-beta 2, is specifically induced in the limb bud cells upon treatment of embryos with teratogenic doses of RA, we investigated if this receptor played a role in teratogenesis by regulating the ...

Effects of retinoic acid on the expression of retinoic acid receptors during zebrafish embryogenesis
Mechanisms of Development, 1994The cDNAs encoding the zebrafish homologs of retinoic acid receptor alpha(zRAR alpha) and gamma (zRAR gamma) were isolated and their expression studied in normal and retinoic acid (RA) treated embryos. Expression boundaries in the central nervous system are clearly different from those observed in the mouse, which can only partly be explained by ...

AIDS, 1994
To analyze the effect of retinoic acids (RA) on HIV-1 expression and correlate this effect with expression levels of RA receptors (RARs) in T-lymphoid and monocytoid cell lines.The effect of all-trans and 9-cis RA on HIV-1 production in T-lymphoid (H9, CEM) and monocytoid (U937,THP-1) cell lines was measured during acute and chronic infection.
