Transcription profiling of human neuroblastoma cells lines following DAC and ATRA treatment

Project description:Following treatment with the de-methylating agent 5-aza-deoxycytidine (DAC), the gene expression profiles of neuroblastoma cell lines Kelly, SK-N-AS and NGP were analysed in order to examine the relationship between transcriptional re-activation and promoter region DNA methylation.<br>In addition, the neuroblastoma cell line SK-N-BE was treated with all-trans-retinoic acid (ATRA) in order to examine the impact this differentiation agent has on DNA methylation status.

Glycosyl-T expression in NB cells

Project description:Dr. Ladisch's work focuses on the establishment of the biological significance of gangliosides that are shed by tumor cells, particularly those involved in pediatric cancers, including brain tumors and neuroblastoma. These studies are directed toward illuminating the hypothesis that shed gangliosides enhance tumor formation, possibly both by inhibiting the antitumor immune response and by enhancing growth factor-induced signaling and proliferation of fibrobalsts and vascular endotheilial cells in the tumor microenvironment. Delineation of the signaling pathways affected by ganglioside exposure is currently under study. The effect of retinoic acid on the mRNA levels of ganglioside glycosyltransferases in neuroblastoma cells in vitro Experiment to determine mRNA expression for ganglioside glycosyltransferases in NB cells (untreated versus treated with ATRA) using the Glyco-gene Chip by the Consortium for Functional Glycomics. Human NB cell lines LAN-5 were incubated with 10 µM of all-trans retinoic acid or untreated as control, and total RNA harvested after 24 hours, 72 hours and 120 hours of exposure to retinoic acid. We performed three independent experiments on either cell line so that for each cell line and each time point three replicates were be obtained (total: 18 chips). Glycosyltransferases of particular interest are LacCer synthase, GlucCer synthase, GM3 synthase, GD3 synthase, GM2/GD2 synthase, GD1b/GM1a synthase, GT1b/GD1a synthase and GQ1b/GT1a synthase.

Cole Lab Fred- genotypeRA experiment

Project description:Mammalian lung development during the saccular and alveolar stages is dependent upon antagonistic molecular signalling by endogenous retinoic acid (RA) and glucocorticoids (GCs) which regulate gene expression via the retinoic acid receptor (RAR) family and the glucocorticoid receptor (GR), respectively. The genomic mechanism of this antagonism was investigated with in vitro distal lung explant cultures from E18.5 GR-null (GR-/-) mice treated with all-trans-RA (atRA) for 2h . Whole mouse genome microarray analysis from lung explant tissue identified a small number of gene targets which were not only significantly induced by atRA in the wildtype lung, but also significantly stimulated to levels greater than atRA-treated wildtype lungs in GR-/- lungs.

RNA seq of HL-60 cells in untreated, ATRA (All- trans retinoic acid) and Vitamin D3 treated conditions

Project description:The leukemic cell line HL-60 is widely used to study normal and aberrant myelopoiesis. HL-60 cells can be treated with ATRA (all-trans retinoic acid) and Vit-D3 (1,25-Dihydroxyvitamin D3, calcitriol) to differentiate into granulocytes and monocytes respectively. Induced myeloid differentiation helps us to understand the molecular basis of myeloid differentiation. To understand the genome-wide gene expression changes associated with HL-60 cells upon myeloid differentiation, RNA-sequencing was carried out. We subjected the HL-60 cells with 10 µM ATRA and 50 nM Vit-D3 for 72 hours. Post induction, the uninduced and induced cells were sorted based on CD11b and CD14 markers. The uninduced cells were negative for both the markers while ATRA and Vit D3 inductions were highly positive for CD11b-FITC and CD14-APC-H7 markers respectively. Two biological replicates were used for this experiment. Sorted cells were collected for RNA extraction using RNAeasy Kit from Qiagen and RNA quality was assessed using Bioanalyzer. High quality RNA with RIN values greater than 8, were used to generate library using TrueSeq stranded library preparation kit from Illumina following manufacturer’s instructions. Finally, barcoded libraries were pooled, and a final concentration of 10 nM was loaded in HiSeq 2500 Illumina platform and paired-end sequencing for 2*126 cycles were carried out.

HIC1 interacts with FOXP3 multi protein complex: a novel mechanism to regulate human regulatory T cell differentiation and function

Project description:Recent data have shown that Hypermethylated in cancer 1 (HIC1) is an important contributor to iTreg cell development and function. Using affinity-purification and tandem mass spectrometry we systematically characterized the HIC-1 interactome in human iTreg cells. On the basis of these data, we have shown that HIC1 is a part of FOXP3-RUNX1-CBFβ protein complex that regulates Treg signature genes and is indispensable for the suppressive function of FOXP3+ regulatory T cells. SRM was used to validate HIC1 interactors
