Transcription profiling of blasts from three APL patients expressing PML/RAR before and after treatment with 1 uM retinoic acid (RA) in vitro for four hours

Project description:Gene expression profiles in blasts from three APL patients expressing PML/RAR were assessed before and after treatment with 1 uM retinoic acid (RA) in vitro for four hours. We then studied a U937 clone conditionally expressing PML/RAR (U937-PR), (Grignani et al. 1993) (Alcalay et al. 2003), and compared the gene expression profile prior to and after 4 hours of treatment with 1 uM RA, to that obtained from a cell line bearing an empty vector (U937-MT). For each sample, biotinylated cRNA targets were synthesized starting from 5ug of total RNA, and hybridized to the complete set of HG-U133 Affymetrix oligonucleotide chips, which explores the expression of approximately 45,000 human transcripts. Results were analyzed using MASv5 and further elaborated with the GenePicker software. GeneChip probe sets regulated by RA in each sample were clustered into non-redundant regulated genes according to UniGene release Hs.166.

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.

MicroRNA profiling shows different response to retinoids in estrogen-receptor positive and negative cells

Project description:This Series reports results of miRNA profiling of estrogen-receptor-positive (MCF7) and estrogen-receptor-negative (MDA-MB-231) cells. Retinoic Acid (RA) induces mir-21 in MCF-7 but not in MDA-MB-231 cells. MCF-7 and MDA-MB-231 cells were treated (or not) with retinoic acid (RA) and grown for either 6 hours or 48 hours.

Gene expression from fibroblast-like synoviocytes (FLS) of three patients with rheumatoid arthritis (RA) that were cultured in four conditions: control medium (Basal), ATRA, TNF and ATRA+TNF.

Project description:The aim of this study was to investigate the response of FLS from RA patients to retinoic acid and retinoic acid combined with the central cytokine of RA, TNF.

RNA-Seq of SH-SY5Y cells after DLG2 overexpression

Project description:The aim of this experiment is to study the gene expression response of DLG2 overexpression in neuroblastoma. Four different conditions were compared in neuroblastoma SH-SY5Y cells, with 4 biological replicates each: 1) Control (no DLG2 overexpression, no retinoic acid treatment), 2) RA (no DLG2 overexpression, retinoic acid treatment), 3) DLG2 (DLG2 overexpression, no retinoic acid treatment), 4) DLG2-RA (DLG2 overexpression, retinoic acid treatment)

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.

10x Genonics Drop-seq single-cell RNA-seq of neonatal (P1.5) testis cells from mice treated with DMSO or Retinoic Acid.

Project description:To reveal distinct transcriptomes associated with response of neonatal prospermatogonia to retinoic acid (RA), unselected testis cells from animals treated with RA or DMSO were used for 10x Genomics analysis 12 hours after treatment at P1.

Genome wide expression analysis of Ctbp2 knock down mouse F9 cells

Project description:Using an RNA interference-based genetic screen in mouse F9 cells we identify the transcriptional corepressor CTBP2 as a coactivator critically required for retinoic acid (RA)-induced transcription. Here we perfom a whole genome transcriptome analysis in F9 cells expressing shRNA for Ctbp2 and Rxr in the absence or presence of retinoic acid (RA). A total of 2,754 genes were found to be upregulated (>2 fold) and 1518 genes were downregulated (>2 fold) in response to RA treatment in the control cells. We find that around 52% and 55% of upregulated genes are dependent on Ctbp2 and Rxr for activation respectively suggesting that Ctbp2 is a coactivator of RA signaling.
