Abstract

Natural killer (NK) cells are immune cells sensing and eliminating foreign, stressed, transformed, and senescent cells through specialized surface receptors, such as NKG2D, that interacts with several virus- or stress-inducible ligands, including ULBP1 and -2, which are expressed on target cell surfaces. For example, induction of DNA damage or cellular senescence pathways in tumor cells led to upregulation of NKG2D ligands that activate NK cells. Although, both pathways activate p53, the relationship of p53 activation to upregulation of NKG2D ligands has not been addressed. In this study, we report that induction of wild-type p53, but not mutant p53, strongly upregulated mRNA and cell surface expression of ULBP1 and -2, whereas expression of other NK cell ligands was not affected. We defined intronic p53-responsive elements in these two novel p53 target genes. Coculture of wild-type p53-induced human tumor cells with primary human NK cells enhanced NKG2D-dependent degranulation and IFN-γ production by NK cells. Accordingly, treatment of certain wild-type p53-expressing tumor cell lines with the p53-reactivating small molecular compound RITA resulted in upregulation of ULBP2 mRNA and cell surface protein expression. Taken together, our findings define the involvement of p53 in the regulation of specific NKG2D ligands that enhance NK cell–mediated target recognition. One implication of our work is that activating p53 after adoptive transfer of NK cells might constitute an effective combinatorial strategy of NK cell–based immunochemotherapy in cancers in which wild-type p53 function is preserved.

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

  • Some missense mutant proteins can lose the transcriptional effects of wild-type genes, such as keeping PDL1 expression low, making cancer cells more susceptible to cytotoxic T cells and NK cells, limiting the immune system's ability to attack cancer cells.

    “Some missense mutant proteins can lose the transcriptional effects of wild-type genes, such as keeping PDL1 expression levels low, thereby making cancer cells more susceptible to cytotoxic T cells and NK cells, limiting the immune system’s ability to attack cancer cells.”
  • Activating wild-type proteins can increase IFNγ signaling and sensitize tumors to immune checkpoint inhibitors, whereas corresponding mutant proteins can reduce the efficacy of immune checkpoint inhibitors.

    “On the other hand, activating wild-type proteins can increase IFNγ signaling and sensitize tumors to immune checkpoint inhibitors, whereas corresponding mutant proteins can reduce the efficacy of immune checkpoint inhibitors.612–614”
  • The status of genes can influence tumor cells through the impact of wild-type gene loss and through their effects on the tumor immune microenvironment.

    “In brief, the status of genes can influence tumor cells not only through the impact of wild-type gene loss but also through their effects on the TIME.”
  • Pharmacological reactivation of p53 in specific cell lines can stimulate the expression of ULPB2, a ligand for human NKG2D.

    “In contrast, two studies reported that pharmacological reactivation of p53 in specific cell lines can stimulate the expression of ULPB2, a ligand for human NKG2D (Li et al., 2011; Textor et al., 2011).”
  • Pharmacological p53 reactivation upregulates NKALs.

    “Additional immunostimulatory effects linked to pharmacological p53 reactivation in cancer cells include (but are not limited to) (1) downregulation of immunomodulatory cytokines linked to tumor progression, such as IL6 (Sahin et al., 2020); (2) upregulation of NKALs (Textor et al., 2011); and (3) establishment of cellular senescence linked to an immunostimulatory SASP that favors the recruitment”

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.
