Abstract

Clear cell renal cell carcinoma, the most common form of kidney cancer, is usually linked to inactivation of the pVHL tumour suppressor protein and consequent accumulation of the HIF-2α transcription factor (also known as EPAS1). Here we show that a small molecule (PT2399) that directly inhibits HIF-2α causes tumour regression in preclinical mouse models of primary and metastatic pVHL-defective clear cell renal cell carcinoma in an on-target fashion. pVHL-defective clear cell renal cell carcinoma cell lines display unexpectedly variable sensitivity to PT2399, however, suggesting the need for predictive biomarkers to be developed to use this approach optimally in the clinic.

  • Those studies used 786-0 cells, which are pVHL-deficient RCC cells lacking HIF-1α, and may have adapted to depend selectively on HIF-2α.

    “However, these studies were performed using 786–0 cells, which are pVHL deficient RCC cells that intrinsically lack HIF-1α expression, and may have thus adapted to selectively depend on HIF-2α [26–28].”

    The supplied Abstract passages identify 786-O as VHL-deficient ccRCC cells lacking wild-type HIF-1α and show HIF-2α-dependent growth. But the paper also studied other cell lines and explicitly says HIF-2α dependence is not linked to HIF-1α status; it does not support the proposed adaptation from HIF-1α loss. Page numbers were not supplied. (LLM, conf=0.88)

  • The initial proposal that HIF-2α is pro-tumorigenic came from studies where HIF-2α overexpression, but not HIF-1α, blocked pVHL re-expression from inhibiting xenograft formation, and HIF-2α shRNA prevented xenograft formation.

    “Specifically, the pro-tumorigenic role of HIF-2α was initially proposed based on studies showing that overexpression of HIF-2α, but not HIF-1α, abrogated the ability of pVHL re-expression to inhibit xenograft formation, and the converse that HIF-2α shRNA prevented tumor xenograft formation [26–28].”

    From Revisiting the HIF switch in the tumor and its immune microenvironment. (2022) · cites this paper as [27]

    The paper’s main text (indexed under Abstract; page unavailable) says that inhibiting A498 tumors was consistent with earlier effects of HIF-2α shRNAs, supporting the claim’s general point that HIF-2α promotes tumor growth. It does not state that shRNA prevented xenograft formation or describe the claimed comparison in which HIF-2α, but not HIF-1α, overexpression overcame inhibition by pVHL re-expression. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • HIF-2α can be targeted by selective inhibitors, and these molecules effectively suppress cancer cell growth and tumor angiogenesis characteristics in ccRCC.

    “Indeed, recent studies have shown that HIF-2α can be targeted by selective inhibitors and have indicated that these molecules effectively suppress cancer cell growth and tumor angiogenesis characteristics in ccRCC79–82.”

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.
