(Submitter supplied) Transmission of the malaria parasite Plasmodium falciparum from the human to the mosquito is mediated by the intraerythrocytic gametocytes, which, once taken up during a blood meal, become activated to initiate sexual reproduction. Because gametocytes are the only parasite stages able to establish an infection in the mosquito, they are crucial for spreading the tropical disease. During gametocyte maturation, different repertoires of genes are switched on and off in a well-coordinated sequence, pointing to regulatory mechanisms of gene expression. more...

(Submitter supplied) Expression profiling the response to inhibition of DNA methylation and histone deacetylation. Comparison of expression in HepG2 cells treated with 5-aza-dC, Trichostatin A, both, or none (control) to change methylation and acetylation status. Background:DNA methylation and histone deacetylation are epigenetic mechanisms that play major roles in eukaryotic gene regulation. We hypothesize that many genes in the human hepatoma cell line HepG2 are regulated by DNA methylation and histone deacetylation. more...

(Submitter supplied) Histone acetylation is involved in the regulation of gene expression in plants and eukaryotes. Histone deacetylases (HDACs) are enzymes that catalyze the removal of acetyl groups from histones, which is associated with the repression of gene expression. To study the role of histone acetylation in the regulation of gene expression during seed germination, trichostatin A (TSA), a specific inhibitor of histone deacetylase, was used to treat imbibing Arabidopsis thaliana seeds. more...

(Submitter supplied) Abstract: We have developed an Entamoeba histolytica genomic DNA microarray and used it to develop a transcriptional profile of 1,971 E. histolytica (HM-1:IMSS) genes. The arrays accurately detected message abundance and 31-47% of amebic genes were expressed under standard tissue culture conditions (levels detectable by Northern blot analysis or RT-PCR respectively). Genes expressed at high levels ( approximately 2% of total) included actin (8.m00351), and ribosomal genes (20.m00312). more...

(Submitter supplied) Entamoeba histolytica is a protozoan parasite which causes colitis and liver abscesses. Using a genomic DNA microarray consisting of 1.6 - 2.0 kb genomic inserts we have generated a transcriptional profile of 1,971 unique parasite transcripts. The arrays in this experiment set were used to (1) estimate relative transcript abundance for Entamoeba histolytica (HM-1:IMSS) trophozoites in mid-logarithmic growth and (2) to examine changes in the transcriptional profile of Entamoeba histolytica when the parasite interacts with colonic epithelial cells (Caco-2). more...

(Submitter supplied) Entamoeba histolytica is a protozoan parasite which causes colitis and liver abscesses. A pilot microarray consisting of 360 unique parasite genes was constructed using identical methods to the larger array (1,971 unique genes). The four arrays in this data set were used to ascertain whether the microarrays would be useful in detecting changes in transcript abundance by exposing parasites to heat shock (42 0C for 1 hr). more...
