Expression data from retinoic acid-sufficient and retinoic acid-deficient human airway smooth muscle [human primary ASMs]

ABSTRACT: Observational studies in human suggest involvement of vitamin A/retinoic acid (RA) signaling in the regulation of airway smooth muscle (ASM) function, but the precise mechanisms by which RA impacts ASM phenotype is not clear. Here, we generated trascriptional profiles from primary human ASM from 3 unrelated donoros cultured in control medium or medium containing BMS493 (an retinoic acid receptor antagonist)

Expression data from retinoic acid-sufficient and retinoic acid-deficient mouse airway smooth muscle [mouse ASMs]

Project description:Observational studies in human suggest involvement of vitamin A/retinoic acid (RA) signaling in the regulation of airway smooth muscle (ASM) function, but the precise mechanisms by which RA impacts ASM phenotype is not clear. Here, we generated trascriptional profiles from two different models of RA-sufficient and RA-deficient mouse ASM in order to determine the molecular targets of RA in ASM (VAS/VAD, CTR/BMS) Mouse ASMs were isolated from Acta2-hrGFP;Cspg4-DsRED adult mice using flow cytometry. VAS mice were given normal, vitamin A-sufficient diet (15 IU vitamin/g) while the VAD mice were given 3 days of vitamin A-deficient diet (< 0.1 IU vitamin/g). CTR/BMS mouse ASMs were also isolated from Acta2-hrGFP;Cspg4-DsRED adult mice using flow cytometry. CTR mice were given 3 days of powdered, vitamin A sufficient diet mixed with vehicles (corn oil) while the BMS diet were given 3 days of powdered, vitamin A sufficient diet mixed with a potent pan-RA-receptor antagonist (BMS, 5 mcg/g).

Zebrafish embryos treated with Retinoic Acid or Retinoic acid antagonist during gastrulation and early somitogenesis.

Project description:Retinoic acid (RA) is an important developmental signaling molecule responsible for the patterning of multiple vertebrate tissues. RA is also a potent teratogen, causing multi-organ birth defects in humans. Endogenous RA levels must therefore be tightly controlled in the developing embryo. In order to understand the RA function and regulation at the genomic level, we used a microarray approach to identify genes that function as negative feedback regulators of retinoic acid signaling. To that end, we treated embryos with different chemicals: DMSO as control, AGN193019 as RA antagonist at high concentration 10uM and low concentration 1uM, as well as 0.33uM RA. Each treatment has four biological replicates. We screened for genes expressed in early somite-stage embryos that respond oppositely to treatment with RA versus RA antagonists, and validated them by whole-mount RNA in situ hybridization.

Retinoic acid-free spheroid culture condition is suitable for growth of TH-MYCN neuroblasts

Project description:It has been already reported that there are undifferentiated/proliferating neuroblasts in the postnatal sympathetic ganglia in TH-MYCN mice. Given the fact that neuroblastoma is derived from sympathoadrenal progenitors which are originated from neural crest stem cells, we attempted to use the well-established culture condition that has been utilized to maintain derivatives of neural crest stem cells. However, the medium contained retinoic acid (RA) which is known to induce neuroblastoma differentiation and is used in clinical treatment against high-risk patients. In the present study, the medium with RA (RA (+) medium) and without RA (RA (-) medium) were compared. Since undifferentiated neuroblasts are observable at one of the sympathetic ganglia, superior mesenteric ganglion (SMG), in 3-week-old TH-MYCN hemizygote (TH-MYCN+/-) mice with 129+Ter/SvJcl mice background, we dissected and dissociated the SMG to prepare single cells. These cells were cultured in either RA (+) or RA (-) media. Spheres formed in either RA (+) or RA (-) medium were subjected to microarray analysis.

Human epidermal keratinocytes treated with retinoic acid or thyroid hormone

Project description:Targets of Retinoic Acid (RA) were identified in primary human epidermal keratinocytes grown in the presence or absence of all-trans retinoic acid for 1, 4, 24, 48 and 72 hours. Targets of Thyroid Hormone (T3) were identified in primary human epidermal keratinocytes grown in the presence or absence of the hormone; same controls as for RA.

H9c2 cell response after retinoic acid stimuli

Project description:During culture, H9c2 cells acquire a myotubule phenotype where a critical component is the inclusion of retinoic acid (RA). The results from some authors on H9c2 suggested that thousands of genes respond to RA stimuli, while other authors report hundreds of genes responding to RA over different cell types. We investigated the response to RA in H9c2 cells controlling for culture time.

Gene regulation by phosphomimetic Myc and retinoic acid

Project description:We aimed to investigate the E-box and Max-independent functions of the oncogene Myc in gene regulation and differentiation of leukemic cells. Expression in HL60 leukemic cells of a mutant form of Myc with impaired Max and E-box interaction by replacing the phosphorylation sites of Pak2 kinase to aspartic acid (MycD), resulted in downregulation of 235 genes and, interestingly, upregulation of 586 genes. Eleven percent of the genes upregulated by MycD coincided with those stimulated by a short treatment of retinoic acid (RA) alone. When leukemic cells expressing MycD were stimulated with RA, the overlap with the RA-alone signature increased to 32% (492/1556 genes). Importantly, 320 of these 492 bona-fide direct RA target genes were specifically superactivated in presence of MycD (MycD+RA>RA), and not by MycA (MycD+RA>MycA+RA), further suggesting a synergy between the two pathways. The list of superactivated genes included important regulators of development and differentiation such as GATA6, ICAM1 and HOX genes, whose expression was validated in independent experiments by RT-qPCR. Induced gene expression in HL60 cells was measured after a short-treatment of retinoic acid (100nM, 4 hours). Cells were either wild-type or expressing ER-tagged MycD or MycA. Four biologically independent experiments were performed at each time.

Robustness of retinoic acid regulatory homeostasis during early development (RNA-seq)

Project description:Retinoic acid (RA) is a central developmental signal whose perturbation results in teratogenic outcomes. RA are tightly regulated during early embryonic development to achieve fine-tuning of the instructive and permissive signals regulating multiple developmental processes including head formation. We aim to identify the key mechanisms underlying the homeostatic regulation and tuning of the retinoic acid signaling levels, the disruption of which in the head lead to wide ranging developmental malformations including microcephaly and other craniofacial defects. We performed transient physiological RA signaling disturbances during Xenopus laevis embryogenesis followed by kinetic RNAseq analysis of the recovery at multiple time points.
