Transcriptome regulation in response to respiratory inhibition with antimycin A in: (a) wild type fission yeast grown in minimal media (EMM) (b) minimal media supplemented with arginine or in (c) strain with deletion of ssp1 gene.

ABSTRACT: We observed that in fission yeast respiration inhibition with drug antimycin A results in arginine auxotrophy. To get insights into transcriptional response for respiratory inhibition and attenuating role of arginine supplementation we performed microarray experiment. Yeast were growing exponentially (OD600 around 0.5) in minimal media (EMM), transcript abundance was monitored immediately prior (Time 0), and 30 and 120 minutes after addition to the media antimycin A (to the concentration 0.15 µg/ml). We performed such experiment for wild type yeast (strain 972 h-), wild type yeast grown in minimal media supplemented with arginine (to the concentration 0.2g/L), and for ssp1 deletion strain grown in minimal media. Ssp1 regulates AMPK kinase and our microarray data show that is can modulate response for respiration block. Two biological samples for each condition (EMM, EMM with arginine and ssp1 deletion) was collected. Part of all the samples were pooled and used as reference in dye swap design.

Communication between mitochondria and nucleus: defining a retrograde response in fission yeast

Project description:Retrograde response was widely studied in budding yeast but the main transcription factors that transmit it (RTG1,2 and 3) are not conserved in other organisms, thus it is interesting to study how communication between mitochondria and nucleus evolved in distantly related fission yeast, and which are the common aspects of this conserved pathway between yeast and higher organisms.To analyse any retrograde response in fission yeast, we inhibited the electron transport chain activity by antimycin A and studied cellular gene expression changes by microarrays. Cells treated with antimycin A in fermentative medium (YE with 3% glucose), showed the same growth rate as untreated cells, but they reached a lower biomass in stationary phase. Antimycin A treated cells consumed glucose at a faster rate and produced more ethanol, indicating that the energy metabolism was shifted even more towards fermentation. We analyzed the transcriptomes of antimycin A-treated cells to untreated control cells during early exponential growth phase (OD 0.5).

Expression data from antimycin A-treated BE(2)-C cells

Project description:Analysis of transcription response of undifferentiated human BE(2)-C neuronal cells to stimulation with purified antimycin A1a or unfractionated commercially available antimycin A (Sigma A8674). Three independent sets of BE(2)-C cells were treated DMSO control or 200 nM of either purified antimycin A1a or unfractionated antimycin A. Total RNA was harvested at 24 h after stimulation and analyzed with Affymetrix U133 Plus 2.0 chips.

Control of RpoS in global gene expression of Escherichia coli in minimal media

Project description:RpoS, an alternative sigma factor, is critical for stress response in Escherichia coli. The RpoS regulon expression has been well characterized in rich media that support fast growth and high growth yields. In contrast, though RpoS levels are high in minimal media, how RpoS functions under such conditions has not been clearly resolved. In this study, we compared the global transcriptional profiles of wild type and an rpoS mutant of E. coli grown in glucose minimal media using microarray analyses. The expression of over 200 genes was altered by loss of RpoS in exponential and stationary phases, with only 48 genes common to both conditions. The nature of the RpoS-controlled regulon in minimal media was substantially different from that expressed in rich media. Specifically, the expression of many genes encoding regulatory factors (e.g., hfq, csrA and rpoE) and genes in metabolic pathways (e.g., lysA, lysC and hisD) were regulated by RpoS in minimal media. In early exponential phase, protein levels of RpoS in minimal media were much higher than that in LB media, which may at least partly account for the observed difference in the expression of RpoS-controlled genes. Expression of genes required for flagellar function and chemotaxis was elevated in the rpoS mutant. Western blot analyses show that the flagella sigma factor FliA was expressed much higher in rpoS mutants than in WT in all phase of growth. Consistent with this, the motility of rpoS mutants was enhanced relative to WT. In conclusion, RpoS and its controlled regulators form a complex regulatory network that mediates the expression of a large regulon in minimal media.
