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.

<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]
