Abstract

Kidney cancers often delete chromosome 3p, spanning the VHL tumor suppressor gene, and chromosome 14q, which presumably harbors ≥1 tumor suppressor genes. pVHL inhibits the hypoxia-inducible transcription factor (HIF), and HIF2α is a kidney cancer oncoprotein. In this article, we identify focal, homozygous deletions of the HIF1α locus on 14q in clear cell renal carcinoma cell lines. Wild-type HIF1α suppresses renal carcinoma growth, but the products of these altered loci do not. Conversely, downregulation of HIF1α in HIF1α-proficient lines promotes tumor growth. HIF1α activity is diminished in 14q-deleted kidney cancers, and all somatic HIF1α mutations identified in kidney cancers tested to date are loss of function. Therefore, HIF1α has the credentials of a kidney cancer suppressor gene. Significance: Deletion of 14q is a frequent event in clear cell renal carcinoma and portends a poor prognosis. In this study, we provide genetic and functional evidence that HIF1α is a target of 14q loss in kidney cancer. Cancer Discovery; 1(3); 222–35. © 2011 AACR.

  • 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].”

    From Revisiting the HIF switch in the tumor and its immune microenvironment. (2022) · cites this paper as [28]

    The Results section ('Frequent Homozygous Deletions of the HIF1α Locus') identifies 786-O as a renal carcinoma line that lacks detectable wild-type HIF1α while producing HIF2α; it also reports an aberrant HIF1α protein, so 'lacking HIF-1α expression' needs that qualification. The Introduction describes HIF2α as a driver in pVHL-defective renal carcinomas, but the paper does not say that 786-O cells adapted to depend selectively on HIF2α, or establish that the cited studies all used 786-O cells.

  • 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 [28]

    The Introduction (page unavailable) reports that HIF-2α, but not HIF-1α, can override pVHL’s tumor-suppressor activity and that eliminating HIF-2α suppresses tumor formation in preclinical models. It does not specify HIF-2α overexpression, pVHL re-expression, HIF-2α shRNA, or xenograft formation as the experiments behind those findings. (LLM, conf=0.84)

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.
