Abstract

Summary: In C andida glabrata , the sirtuins Sir 2 and Hst 1 control the expression of a wide number of genes including adhesins required for host colonization and niacin transporters needed for growth. Given that these sirtuins can be inactivated during infection, we asked if their inhibition could modify the response of C . glabrata to other stressful conditions. Here, we found that deletion of HST1 decreases susceptibility of C . glabrata to fluconazole and hydrogen peroxide. The transcription factor Pdr1 and the ABC transporter Cdr 1 mediated the fluconazole resistance phenotype of the hst1 Δ cells, whereas the transcriptional activator Msn4 and the catalase Cta 1 are necessary to provide oxidative stress resistance. We show that the transcription factor Sum1 interacts with Hst1 and participate in the regulation of these genes. Interestingly, even though C . glabrata and S accharomyces cerevisiae are closely related phylogenetically, deletion of HST1 decreased susceptibility to fluconazole and hydrogen peroxide only in C . glabrata but not in S . cerevisiae , indicating a different transcriptional control by two similar sirtuins. Our findings suggest that Hst 1 acts as a regulator of stress resistance associated‐genes.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lack of the histone deacetylase CgHst1 led to high expression of CgCTA1 and elevated resistance to oxidative stress, which was dependent upon CgMsn4.

    “Additionally, lack of the histone deacetylase CgHst1 led to high expression of CgCTA1 and elevated resistance to oxidative stress, which was dependent upon CgMsn4 [87].”

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.
