Identification of Candida albicans genes differentially expressed in the presence of arachidonic acid

Project description:Although Candida species, more specifically C. albicans, are the most common pathogenic yeasts, little is known about the mechanism involved in eicosanoid production, a virulence factor in these organisms. This is an important area of research which may aid in the understanding of the complex interactions between host and pathogen and may possibly lead to the identification of novel antifungals or drug targets. In this study, genomic hybridization studies using C. albicans DNA microarrays were used to evaluate the regulation of C. albicans biofilm genes during incubation in the presence of arachidonic acid, the major precursor for prostaglandin E2 production. The results obtained indicated that the genes differentially expressed had diverse functions not normally required for cell growth. Two-condition experiment, Control biofilms vs. Arachidonic acid treated biofilms at different time intervals. Biological replicates: 3 Control, 3 Arachidonic acid treated, independently grown and harvested. Technical replicate: dye swap included. Triplicate per array.

Effect of valproic acid on hematopoiesis: A functional profiling and cell phenotyping approach

Project description:Analysis of the effects of valproic acid (VPA) on chronic myelogenous leukemia K562 cells. This study attempts to elucidate the effects of VPA on cell homeostasis and hematopoietic differentiation pathways in this cell line. We used ten experimental conditions comparing valproic acid-treated and untreated cells at time points 2, 6, 10, 48 and 72 hrs respectively. Experiments were performed in three biological replicates including a dye swap (represented by replicate 3, for each timepoint).

4PEHz-treated P.falciparum parasites vs. untreated extracted at timepoints t1 (12 Hours post invasion or HPI), t2 (24 HPI) and t3 (36 HPI)

Project description:Plasmodium falciparum parasites were treated with the PfPdx1 inhibitor 4PEHz and the transcriptional responses of three different timepoints throughout the intraerythrocyic developmental cycle of the parasite were compared to untreated parasites. The goal was to determine the functional consequences of attenuating vitamin B6 metabolism in the parasites using 4PEHz (4-phospho-D-erythronhydrazide) Two color array with reference pool design, at least 2 biological replicates from each timepoint of treated and untreated parasites.

The global expression profile of Bacillus subtilis to the toxic carbonyls methylglyoxal (MG) and formaldehyde (FA)

Project description:Abstract of associated menuscript; Quinones and alpha,beta-unsaturated carbonyls are naturally occurring electrophiles that target cysteine residues via thiol-(S)-alkylation. We analyzed the global expression profile of Bacillus subtilis to the toxic carbonyls methylglyoxal (MG) and formaldehyde (FA). Both carbonyl compounds cause a stress response characteristic for thiol-reactive electrophiles as revealed by the induction of the Spx, CtsR, CymR, PerR, ArsR, CzrA, CsoR and SigmaD regulons. MG and FA triggered also a SOS response which indicates DNA damage. Protection against FA is mediated by both the hxlAB operon, encoding the ribulose monophosphate pathway for FA fixation, and a thiol-dependent formaldehyde dehydrogenase (AdhA) and DJ-1/PfpI-family cysteine proteinase (YraA). The adhA-yraA operon and the yraC gene, encoding gamma-carboxymuconolactone decarboxylase, are positively regulated by the MerR-family regulator, YraB(AdhR). AdhR binds specifically to its target promoters which contain a 7-4-7 inverted repeat (CTTAAAG-N4-CTTTAAG) between the -35 and -10 elements. Activation of adhA-yraA transcription by AdhR requires the conserved Cys52 residue in vivo. We speculate that AdhR is redox-regulated via thiol-(S)-alkylation by aldehydes and that AdhA and YraA are specifically involved in reduction of aldehydes and degradation or repair of damaged thiol-containing proteins, respectively. WT (-FA) vs. WT (+ 1 mM FA), WT (-MG) vs. WT (+ 2.8 mM MG), WT (-MG) vs. WT (+ 5.6 mM MG). Each experiement was conducted triplicates using three independent total RNA preparations. For all datasets used for final analysis, untreated samples were labeled with Cy3 and treated samples with Cy5.

H4IIE liver cell line ChIP-Chip with Egr1

Project description:Egr1 regulates genes involved in cholesterol biosynthesis in liver. ChIP-chip assays were performed on H4IIE liver cells that were either treated or untreated with insulin for one hour. This experiment includes a custom ChIP-chip design incorporating many genes that are dynamically regulated by insulin signaling. The Egr1 antibody used was from Santa Cruz sc-189. Egr1 ChIP samples from untreated and 1h insulin treated cells were hybridized.

Saccharomyces cerevisiae mutant strain with R1158 strain background: Fold change after doxycycline treatment

Project description:To understand the extent that Heat shock protein 90 (Hsp90) regulated its target proteins at the transcription level, transcriptomic change was profiled in yeast cells upon Hsp90 compromising. We genetically modified the R1158 strain (resulting genotype of mutant strain: TETp-HSC82 hsp82Δ arg4Δ lys5Δ car2Δ::URA3) and then reduced the Hsp90 amount with doxycycline treatment. Fold change of mRNA from untreated to treated cells indicated the transcriptomic change. Totally, we identified 1104 genes mis-regulated with a fold change of no less than 1.5 (P <0.05) upon Hsp90 compromising. Two-condition experiment, treated vs. untreated cells. Biological duplicates, independently grown and harvested. Technical triplicates for RNA isolation.
