Expression data of E. histolytica trophozoites treated with 5AzaC

ABSTRACT: Expression profiling of treatment of E. histolytica HM-1:IMSS trophozoites with 5-Aza cytidine, an inhibitor of DNA methyltransferase Keywords: drug treatment HM1 trophozoites were treated for 3 or 7 days with 23 micromolar 5-Aza cytidine, and RNA extracted and analyzed on a custom Affymetrix array. Data from these two arrays is to be compared to expression data from HM1 trophozoites grown without drug exposure.

Growth of the protozoan parasite Entamoeba histolytica in 5-azacytidine has limited effects on parasite gene expression.

BMC genomics 20070105

<h4>Background</h4>In higher eukaryotes DNA methylation regulates important biological functions including silencing of gene expression and protection from adverse effects of retrotransposons. In the protozoan parasite Entamoeba histolytica, a DNA methyltransferase has been identified and treatment with 5-azacytidine (5-AzaC), a potent inhibitor of DNA methyltransferase, has been reported to attenuate parasite virulence. However, the overall extent of DNA methylation and its subsequent effects o ...[more]

Gene expression in Entamoeba histolytica cysts and trophozoites

Project description:We compared multiple strains of lab trophozoites to recent clinical isolates. Clinical isolates were grown in xenic media, and maintained many characteristics of the cyst stage of devlopment Keywords: Stage conversion E. histolytica trophozoites of three different strains (HM1:IMSS, Rahman, and 200:NIH) and grown under multiple conditions (Long term axenic growth in TYI, Growth in low glucose media, Mouse adapted parasites and in vivo growth in a mouse model) were compared to recent clinical isolates that had grown in xenic culture for 1-8 weeks.

Project description:We examined the stress response in Entamoeba histolytica trophozoites by comparing untreated log-phase HM-1:IMSS trophozoites to those subjected to heat shock at 42C for 1 hour. Keywords: stress reponse We compared two arrays from normal trophozoites to two arrays from trophozoites subjected to heat shock.

Effects of overexpression of EhMyb-dr on transcription in Entamoeba histolytica

Project description:A myb domain containing protein of the SHAQKY family, EhMyb-dr, was overexpressed in E. histolytica trophozoites, and effects on transcription were measured. Two arrays of trophozoites expressing Myc tagged EhMyb-dr were compared to two arrays performed on wild type trophozoites. The effects of transfection and drug were controlled for by including data from trophozoites expressing irrelevant plasmids, and grown in the same level of G418. All parasites were of strain HM-1:IMSS

Effect of treatment with H2O2 or DPTA-NONOate on E. histolytica

Project description:E. histolytica of strains HM1:IMSS (virulent) and Rahman (avirulent) were examined for response to oxidative and nitrosative stress. Response to oxidative stress in E. histolytica was assayed by treating Eh (HM1:IMSS) and Eh (Rahman) with 1mM H2O2 for 60 minutes or 90 minutes and comparing transcription to parasites grown in TYI. In addition, response to nitosative stress was assayed in Eh (HM1:IMSS) by treatment for 60 minutes with 200 µM DPTA-NONOate.

Effect of Rom1 silencing on gene expression in Entamoeba histolytica

Project description:Entamoeba histolytica trophozoites epigenetically silenced for ameobapore A (G3 parasites) were additionally silenced for the Rhomboid gene Rom1 (EHI_197460) using the mechanism outlined in Mirelman et al. Parasite. 2008 Sep;15(3):266-74 (PMID 18814693). Rom1 silencing was confirmed by RT-PCR. Gene expression in these parasites was compared to that of the parent G3 strain. RNA was isolated from axenically grown G3 and Rom1 silenced parasites, and hybridized to a custom Affymetrix array for E. histolytica. Two biological replicates were performed for each condition.

Characterization of an Entamoeba histolytica High-Mobility-Group Box Protein Induced during Intestinal Infection

Project description:The unicellular eukaryote Entamoeba histolytica is a human parasite that causes amebic dysentery and liver abscess. A genome-wide analysis of gene expression modulated by intestinal colonization and invasion identified an up-regulated transcript that encoded a putative high-mobility-group box (HMGB) protein, EhHMGB1. We tested if EhHMGB1 encoded a functional HMGB protein, and determined its role in control of parasite gene expression. Recombinant EhHMGB1 was able to bend DNA in vitro, a characteristic of HMGB proteins. Core conserved residues required for DNA bending activity in other HMGB proteins were demonstrated by mutational analysis to be essential for EhHMGB1 activity. EhHMGB1 was also able to enhance the binding of human p53 to its cognate DNA sequence in vitro, which is expected for an HMGB1 protein. Confocal microscopy, using antibodies against the recombinant protein, confirmed its nuclear localization. Overexpression of EhHMGB1 in HM1: IMSS trophozoites led to modulation of 33 transcripts involved in a variety of cellular functions. Of these, twenty were also modulated at either day one or day 29 in the mouse model of intestinal amebiasis. Notably, four transcripts with known roles in virulence, including two encoding Gal/GalNAc lectin light chains, were modulated in response to EhHMGB1 overexpression. We concluded that EhHMGB1 was a bona fide HMGB protein with the capacity to recapitulate part of the modulation of parasite gene expression seen during adaptation to the host intestine. 6 samples for two groups: 3M and Gir. Each groups contain 3 samples

Expression data comparing azacitidine and decitabine in non-small cell lung cancer lines

Project description:Azacitidine (AZA) and decitabine (DAC) are cytidine azanucleoside analogs with clinical activity in myelodysplastic syndromes (MDS) and potential activity in solid tumors. To better understand the mechanism of action of these drugs, we examined the effects of AZA and DAC in a panel of non-small cell lung cancer (NSCLC) cell lines. Of 5 NSCLC lines tested in a cell viability assay, all were sensitive to AZA (EC50 of 1.8M-bM-^@M-^S10.5 M-BM-5M), while only H1299 cells were equally sensitive to DAC (EC50 of 5.1 M-BM-5M). In the relatively DAC-insensitive cell line A549, both AZA and DAC caused DNA methyltransferase I depletion and DNA hypomethylation; however, only AZA significantly induced markers of DNA damage and apoptosis, suggesting that mechanisms in addition to, or other than, DNA hypomethylation are important for AZA-induced cell death. Cell cycle analysis indicated that AZA induced an accumulation of cells in sub-G1 phase, whereas DAC mainly caused an increase of cells in G2/M. Gene expression analysis of AZA- and DAC-treated cells revealed strikingly different profiles, with many genes distinctly regulated by each drug. In summary, while both AZA and DAC caused DNA hypomethylation, distinct effects were demonstrated on regulation of gene expression, cell cycle, DNA damage, and apoptosis. A549 and H1299 cells were treated with a dose range (0.3M-bM-^@M-^S3.0 M-NM-<M) of AZA or DAC for 48 hours, and effects on gene expression were assessed by microarray analysis.
