Project description:As Trypanosoma cruzi, the etiological agent of Chagas disease, multiplies in the cytoplasm of nucleated host cells, infection with this parasite is highly likely to affect host cells. We performed an exhaustive transcriptome analysis of T. cruzi-infected HeLa cells using an oligonucleotide microarray containing probes for greater than 47,000 human gene transcripts. In comparison with uninfected cells, those infected with T. cruzi showed greater than threefold up-regulation of 41 genes and greater than threefold down-regulation of 23 genes. Real-time reverse transcriptase-polymerase chain reaction (RT-PCR) of selected, differentially expressed genes confirmed the microarray data. Many of these up- and down-regulated genes were related to cellular proliferation, including seven up-regulated genes encoding proliferation inhibitors and three down-regulated genes encoding proliferation promoters, strongly suggesting that T. cruzi infection inhibits host cell proliferation, which may allow more time for T. cruzi to replicate and produce its intracellular nests. These findings provide new insight into the molecular mechanisms by which intracellular T. cruzi infection influences the host cell, leading to pathogenicity. Keywords: infection response

Project description:To generate a high quality, annotated gene expression database of T. cruzi trypomastigotes(TRP), amastigotes (AMA), epimastigotes (EPI), and metacyclic trypomastigotes (MET). The global assessment of transcript abundances in each life-cycle stage of T. cruzi will identify stage-regulated genes and provide an essential element of an integrated database of T. cruzi genomic, proteomic, and transcriptomic data. RNAs from 3 biological replicates from a single time point in each stage will be subjected to DNA microarrays containing probes for the complete, annotated T. cruzi genome, as it is currently known. The arrays for this project will be provided by the Pathogen Functional Genomics Resource Center (PFGRC) at The Institute for Genomic Research (TIGR) sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), and will contain long oligonucleotides complementary to every annotated gene in the newly sequenced T. cruzi genome. The resulting data and analysis results will be deposited in TcruziDB (http://TcruziDB.org). Keywords: Gene expression comparisons between the four life-cycle stages of T. cruzi

Project description:Trypanosoma cruzi is a protozoan parasite and the etiologic agent of Chagas disease, an important public health problem in Latin America. T. cruzi is diploid, almost exclusively asexual, and displays an extraordinarily diverse population structure both genetically and phenotypically. Yet, to date the genotypic diversity of T. cruzi and its relationship, if any, to biological diversity have not been studied at the whole genome level. In this study, we used whole genome oligonucleotide tiling arrays to compare gene content in biologically disparate T. cruzi strains by comparative genomic hybridization (CGH). We observed that T. cruzi strains display widespread and focal copy number variations (CNV) and a substantially greater level of diversity than can be adequately defined by the current genetic typing methods. As expected, CNV were particularly frequent in gene family-rich regions containing mucins and trans-sialidases but were also evident in core genes. Gene groups that showed little variation in copy numbers among the strains tested included those encoding protein kinases and ribosomal proteins, suggesting these loci were less permissive to CNV. Moreover, frequent variation in chromosome copy numbers were observed, and chromosome-specific CNV signatures were shared by genetically divergent T. cruzi strains, suggesting a greater degree of chromosome exchange than previously thought.
