Project description:Ureaplasma are widespread parasites colonizing the mucosal surface of the human urogenital tract, and it has been suspected as a causative agent of nongonococcal urethritis, pregnancy complications and prenatal infections. Ureaplasma may also cause central nervous system infections and affect the lower respiratory tract of newborn babies. However, Ureaplasma spp. have also been detected in the urogenital tracts of clinically healthy patients, and their role in the development of infections thus remains unclear. Like in other organisms, virulence of Ureaplasma is determined by the presence of virulence factors - adhesions, human IgA protease, phospholipase and urease. However, the existence of interrelationships between the presence of these genes in the Ureaplasma genome and the incidence of diseases in man has not been demonstrated. Difficulties in the elucidation of these interrelationships may arise from significant macro- (gene mutation, chromosomal rearrangements) and micro- (nucleotide polymorphism) genomic heterogeneity. It is possible that the combination of the variable strain-specific genes in Ureaplasma with generally known virulence factors determine the development of pathological processes on the mucosal surface of the human urogenital tract. Keywords: macroarray, variability of genome, Ureaplasma parvum

Project description:Cryptosporidium parvum is an important opportunistic parasite pathogen for immunocompromised individuals and a common cause of diarrhea in young children in developing countries. Infection by this parasite causes significant alterations in the gene expression profiles in infected host cells. This study aims to measure the genomic wide alterations in gene expression profiles in host intestinal epithelial cells following C. parvum infection. Mouse intestinal epithelial (IEC4.1) cells were grown to 80% confluence and exposed to C. parvum infection for 24h. Total RNA was collected for the genome-wide analysis. The Agilent SurePrint G3 mouse Gene Expression Microarray (G4852A) was used for the genome-wide analysis, which provides full coverage of genes and transcripts with the most up-to-date content, including mRNAs and lincRNAs (http://www.chem.agilent.com/store/en_US/Prod-G4852A/G4852A).
