Abstract

Defective function of the von Hippel-Lindau (VHL) tumor suppressor ablates proteolytic regulation of hypoxia-inducible factor alpha subunits (HIF-1alpha and HIF-2alpha), leading to constitutive activation of hypoxia pathways in renal cell carcinoma (RCC). Here we report a comparative analysis of the functions of HIF-1alpha and HIF-2alpha in RCC and non-RCC cells. We demonstrate common patterns of HIF-alpha isoform transcriptional selectivity in VHL-defective RCC that show consistent and striking differences from patterns in other cell types. We also show that HIF-alpha isoforms display unexpected suppressive interactions in RCC cells, with enhanced expression of HIF-2alpha suppressing HIF-1alpha and vice-versa. In VHL-defective RCC cells, we demonstrate that the protumorigenic genes encoding cyclin D1, transforming growth factor alpha, and vascular endothelial growth factor respond specifically to HIF-2alpha and that the proapoptotic gene encoding BNip3 responds positively to HIF-1alpha and negatively to HIF-2alpha, indicating that HIF-1alpha and HIF-2alpha have contrasting properties in the biology of RCC. In keeping with this, HIF-alpha isoform-specific transcriptional selectivity was matched by differential effects on the growth of RCC as tumor xenografts, with HIF-1alpha retarding and HIF-2alpha enhancing tumor growth. These findings indicate that therapeutic approaches to targeting of the HIF system, at least in this setting, will need to take account of HIF isoform-specific functions.

  • The HIF-2α bias in ccRCC is attributed to HIF-2α being more potent than HIF-1α at inducing pro-tumorigenic factors such as Cyclin D1, TGF-α, VEGFA, c-Myc, and β-catenin.

    “The HIF-2α bias observed in ccRCC has been attributed to the increased potency of HIF-2α compared to HIF-1α in promoting pro-tumorigenic factors such as Cyclin D1, TGF-α, VEGFA, c-Myc and β-catenin [14,18–20].”

    The Discussion (p. 5683) reports that HIF-2α, unlike HIF-1α, positively regulates cyclin D1, TGF-α and VEGF in VHL-defective renal carcinoma cells. It does not establish HIF-2α promotion of c-Myc or β-catenin, and the Discussion says the authors could not determine what drives the observed HIF-2α bias. (LLM, conf=0.87)

  • Early studies showed that HIF-1 (but not HIF-2) induced expression of several glycolytic genes in various cell types, while unique HIF-2 target genes seemed to be cell type specific.

  • HIF transcriptional target specificity was strikingly different in VHL-defective RCC cells compared to other cell types, and the HIF isoforms also showed a mutually dependent suppressive function in RCC.

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.
