Abstract

Mitochondrial dysfunction can lead to diverse cellular and organismal responses. We used DNA microarrays to characterize the transcriptional responses to different mitochondrial perturbations in Saccharomyces cerevisiae. We examined respiratory-deficient petite cells and respiratory-competent wild-type cells treated with the inhibitors of oxidative phosphorylation antimycin, carbonyl cyanide m-chlorophenylhydrazone, or oligomycin. We show that respiratory deficiency, but not inhibition of mitochondrial ATP synthesis per se, induces a suite of genes associated with both peroxisomal activities and metabolite-restoration (anaplerotic) pathways that would mitigate the loss of a complete tricarboxylic acid cycle. The array data suggested, and direct microscopic observation of cells expressing a derivative of green fluorescent protein with a peroxisomal matrix-targeting signal confirmed, that respiratory deficiency dramatically induces peroxisome biogenesis. Transcript profiling of cells harboring null alleles of RTG1, RTG2, or RTG3, genes known to control signaling from mitochondria to the nucleus, suggests that there are multiple pathways of cross-talk between these organelles in yeast.

  • This aspect of the response shows some similarities between C. albicans and S. cerevisiae, as DIC1 and PEX11 are upregulated in respiratory-deficient ρ0 strains in S. cerevisiae, albeit by a different mechanism that does not involve the Rtg1/Rtg3 transcription factors.

    “This aspect of the response shows some similarities between C. albicans and S. cerevisiae, as DIC1 and PEX11 are upregulated in the respiratory-deficient ρ0 strains in the latter, albeit by a different mechanism that does not involve the Rtg1/Rtg3 transcription factors (Epstein et al. 2001).”

  • Only two C. albicans Rtg targets, DIC1 and PEX11, were found to be upregulated in respiratory-deficient strains of S. cerevisiae, albeit in a manner that does not depend on the Rtg transcription factors.

    “Yet, only two of them—DIC1 and PEX11 were found to be upregulated in respiratory-deficient strains of S. cerevisiae, albeit in a manner that does not depend on the Rtg transcription factors (Epstein et al. 2001; Guaragnella et al. 2018).”

    The Supplementary Material reports that DIC1 and PEX11 are upregulated in respiratory-deficient S. cerevisiae (ρ° cells), by 5.0- and 2.4-fold, respectively. The RTG Genes passage describes some induced genes as nearly RTG-independent, but does not establish that for DIC1 or PEX11 specifically. This paper also does not identify them as C. albicans Rtg targets or establish the 'only two' comparison. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
