MetabolomicsDiagnostic metabolite biomarkers of chronic typhoid carriage
Background: Salmonella Typhi and Salmonella Paratyphi A are the agents of enteric (typhoid) fever; both can establish chronic carriage in the gallbladder. Chronic Salmonella carriers are typically asymptomatic, intermittently shedding bacteria in the feces, and contributing to disease transmission. ...

TranscriptomicsComparative genomic hybridization of Saccharomyces boulardii and Saccharomyces cerevisiae to determine genomic differences
A comparative genomic hybridisation experiment using Affymetrix YG-S98 arrays to study the genetic background of S. Boulardii compared to S. Cerevisiae strain BY4743. Background: Saccharomyces boulardii, a yeast that was isolated from fruit in Indochina has been used as a remedy for diarrhoea since ...

TranscriptomicsS phase and HU profiles in wild-type and mutant cells
Total S phase was measured for wild-type cells undergoing meiS and mitS. Early replication origins were mapped in mitS in wild-type cells, and in meiS for wild-type, sml1 delete, rec8 delete and spo11 delete cells. Comparative genome hybridization was used to measure the kinetics and final extent of...

TranscriptomicsWidespread Use of Non-Productive Alternative Splice Sites in Saccharomyces cerevisiae
Using RNA-Seq analysis of nonsense-mediated mRNA decay (NMD) mutant strains, we show that many Saccharomyces cerevisiae intron-containing genes exhibit usage of alternative splice sites, but most transcripts generated by splicing from these sites are non-functional because they introduce premature t...

TranscriptomicsRole of Histone Ubiquitylation and Deubiquitylation as Determined by the Analysis of an HTB1_K123R S. cerevisiae Strain
In Saccharomyces cerevisiae histone H2B is ubiquitylated at lysine 123. The SAGA complex component, Ubp8, is one of two proteases that remove this ubiquitin moiety. We analyzed gene expression in a strain containing a variant of histone H2B with lysine 123 converted to arginine to address the mechan...

TranscriptomicsComparative genomic hybridization of forty clinical isolates from twelve common serovars within Salmonella enterica subspecies I (sspI) to identify the conserved gene pool present
We have performed microarray hybridization studies on forty clinical isolates from twelve common serovars within Salmonella enterica subspecies I (sspI) to identify the conserved gene pool present.

TranscriptomicsGene profiling of TRA1 and tra1-L3733A
Tra1 is a component of the Saccharomyces cerevisiae SAGA and NuA4 complexes and a member of the phosphatidylinositol 3-kinase kinase family that contain a C-terminal PI3K domain followed by a 35-residue FATC domain. We analyzed alleles with single residue changes in the FATC domain. Of these tra1-L3...

TranscriptomicsSeparation of DNA replication from the assembly of break-competent meiotic chromosomes
The meiotic cell division reduces the chromosome number from diploid to haploid to form gametes for sexual reproduction. Although much progress has been made in understanding meiotic recombination and the two meiotic divisions, the processes leading up to recombination, including the prolonged pre-m...
