Abstract

Majority of cancer cells upregulate co‐inhibitory molecule B7‐H1 which confers resistance to anti‐tumor immunity, allowing cancers to escape from host immune surveillance. We addressed the molecular mechanism underlying the regulation of cancer‐associated B7‐H1 expression in response to interferon‐γ (IFN‐γ). Using promoter constructs in luciferase assay, the region between 202 and 320 bp from the translational start site is responsible for B7‐H1 expression. Electrophoretic mobility shift assay, site‐directed mutagenesis and knockdown experiment using siRNA revealed that interferon regulatory factor‐1 (IRF‐1) is primarily responsible for the constitutive B7‐H1 expression as well as for the IFN‐γ‐mediated B7‐H1 upregulation in a human lung cancer cell line A549. Additionally, AG490, a Janus activated kinase/signal transducer and activator of transcription inhibitor, greatly abolished the responsiveness of A549 cells to IFN‐γ by reducing the IRF‐1 transcription. Our findings support a critical role of IRF‐1 in the regulation of constitutive and IFN‐γ‐induced expression of B7‐H1 in cancer cells.

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.
