(Submitter supplied) Iron is an essential cofactor for enzymes involved in numerous cellular processes. We analyzed the metabolomes and transcriptomes of yeast grown in iron-rich and iron-poor media to determine which biosynthetic processes are altered when iron availability falls.

(Submitter supplied) The Saccharomyces cerevisiae transcription factor Aft1 is activated in iron-deficient cells to induce the expression of iron regulon genes, which coordinate the increase of iron uptake and remodel cellular metabolism to survive low iron conditions. In addition, Aft1 has been implicated in numerous cellular processes including cell cycle progression and chromosome stability; however it is unclear if all cellular effects of Aft1 are mediated through iron homeostasis. more...

(Submitter supplied) We performed transcriptional and metabolic profiling for yeast at early stages of senescence (4th, 7th and 11th generation), that is, for populations in which most cells are still alive. Transcriptional profiles showed up- and down-regulation for about 20% of the genes profiled after the first 4 generations, few further changes by the 7th generation, and an additional 12% of the genes were up- and down-regulated after 11 generations. more...

(Submitter supplied) The COP9 signalosome (CSN) is a highly conserved eukaryotic protein complex which regulates the Cullin-RING family of ubiquitin ligases and carries out a deneddylase activity that resides in subunit 5 (CSN5). The budding yeast CSN is biochemically active and deletion mutants of each of its subunits exhibit deficiency in deneddylation of cullins, although the biological context of this activity is still unknown in this organism. more...

(Submitter supplied) The budding yeast S. cerevisiae responds to depletion of iron in the environment by activating Aft1p, the major iron-dependent transcription factor, and by transcribing systems involved in the uptake of iron. Here we have studied the transcriptional response to iron deprivation, and have identified new Aft1p target genes. We find that other metabolic pathways are regulated by iron: biotin uptake and biosynthesis, nitrogen assimilation, and purine biosynthesis. more...

(Submitter supplied) Saccharomyces cerevisiae is unique among yeasts for its ability to grow rapidly in the complete absence of oxygen. S. cerevisiae is therefore an ideal eukaryotic model to study physiological adaptation to anaerobiosis. Recent transcriptome analyses have identified hundreds of genes that are transcriptionally regulated by oxygen availability but the relevance of this cellular response has not been systematically investigated at the key control level of the proteome. more...

(Submitter supplied) Sampangine, a plant-derived alkaloid found in the Annonaceae family, exhibits strong inhibitory activity against the opportunistic fungal pathogens Candida albicans, Cryptococcus neoformans and Aspergillus fumigatus. In the present study, transcriptional profiling experiments coupled with the analysis of mutants were performed in an effort to elucidate its mechanism of action. Using Saccharomyces cerevisiae as a model organism, we show that sampangine produces a transcriptional response indicative of hypoxia, altering the expression of genes known to respond to low oxygen conditions. more...

Herein, we explored how Saccharomyces cerevisiae (budding yeast) respond to trivalent arsenic (arsenite) by quantitative and kinetic transcriptome, proteome and sulfur metabolite profiling. Arsenite exposure affected transcription of genes encoding functions related to protein biosynthesis, arsenic detoxification, oxidative stress defense, redox maintenance and proteolytic activity. more...
