Abstract

Significance Cytotoxic chemotherapy is frequently used in patients with triple-negative breast cancer (TNBC). Although patients initially respond to the treatment, the cancer often comes back and kills the patient. Recent studies have demonstrated that cancer cells express genes that protect them from killing by immune cells, but the stimulus that prompts this response is unknown. We show that when TNBC cells are treated with chemotherapy, the surviving cells turn on genes that enable them to escape killing by the immune system. We identify hypoxia-inducible factors (HIFs), which are known to promote metastasis of TNBC, as responsible for this countertherapeutic effect. We show that coadministration of an HIF inhibitor with chemotherapy blocks the ability of surviving TNBC cells to evade the immune system.

  • Acriflavine treatment of tumor-bearing mice increases intratumoral CD8+ T cells and NK cells.

    “Acriflavine treatment of tumor-bearing mice was recently reported to increase intratumoral CD8+ T cells and NK cells (42, 43).”

    From HIF inhibitor 32-134D eradicates murine hepatocellular carcinoma in combination with anti-PD1 therapy (2022) · cites this paper as [42]

    In “Acriflavine Blocks Chemotherapy-Induced Immune Evasion in a Syngeneic Mouse Model” (page unavailable), acriflavine coadministration restored intratumoral CD8+ effector T cells reduced by chemotherapy. The paper does not report an increase in intratumoral NK cells with acriflavine; it says carboplatin had no effect on their percentage. The CD8+ finding is also specific to acriflavine given with chemotherapy, not acriflavine treatment alone. (LLM, conf=0.87)

  • In human breast cancer cells, HIF-dependent expression of CD47, CD73, and PDL1 inhibited the ability of both the innate and adaptive immune systems to kill cancer cells.

    “We previously showed that in human breast cancer cells HIF-dependent expression of CD47, CD73, and PDL1 inhibited the ability of both the innate and adaptive immune systems to kill cancer cells (42).”

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.
