Abstract

ABSTRACT During hypoxia, a cellular adaptive response activates hypoxia‐inducible factors (HIFs; HIF‐1 and HIF‐2) that respond to low tissue‐oxygen levels and induce the expression of a number of genes that promote angiogenesis, energy metabolism, and cell survival. HIF‐1 and HIF‐2 regulate endothelial cell (EC) adaptation by activating genesignaling cascades that promote endothelial migration, growth, and differentiation. An HIF‐1 to HIF‐2 transition or switch governs this process from acute to prolonged hypoxia. In the present study, we evaluated the mechanisms governing the HIF switch in 10 different primary human ECs from different vascular beds during the early stages of hypoxia. The studies demonstrate that the switch from HIF‐1 to HIF‐2 constitutes a universal mechanism of cellular adaptation to hypoxic stress and that HIF1A and HIF2A mRNA stability differences contribute to HIF switch. Furthermore, using 4 genome‐wide mRNA expression arrays of HUVECs during normoxia and after 2, 8, and 16 h of hypoxia, we show using bioinformatics analyses that, although a number of genes appeared to be regulated exclusively by HIF‐1 or HIF‐2, the largest number of genes appeared to be regulated by both.—Bartoszewski, R., Moszynska, A., Serocki, M., Cabaj, A., Polten, A., Ochocka, R., Dell'Italia, L., Bartoszewska, S., Króliczewski, J., Dabrowski, M., Collawn, J.

  • In primary human endothelial cells, our analyses uncovered over 150 hypoxia-responsive genes involved in metabolic control and angiogenic regulation, erythropoiesis, autophagy, and pro-survival signaling.

    The Results (page unavailable) report 280 genes affected after 16 hours of hypoxia, with gene-ontology signals for angiogenesis, glycolysis, and antiapoptotic responses. The paper also discusses erythropoietin expression, but the retrieved passages do not establish erythropoiesis or autophagy as functions of the genes identified in its analysis. (LLM, conf=0.87)

  • Diversity in HIF complex composition contributes to cell type-specific hypoxic transcriptional responses.

    “This diversity in HIF complex composition contributes to cell type–specific hypoxic transcriptional responses”

    From HIF inhibition: Current strategies and clinical challenges (2026) · cites this paper as [7]

    The Results report differences in HIF-1α timing among endothelial cells from different vascular beds, and the Discussion links the HIF-1-to-HIF-2 switch to transcriptional consequences in endothelial cells. But the paper does not establish that differences in HIF complex composition cause distinct transcriptional responses across cell types; its gene-expression analysis concerns endothelial cells during hypoxia. The indexed passages provide section labels but no page numbers. (LLM, conf=0.82)

  • The global architecture of HIF-1- and HIF-2-dependent target gene networks remains largely conserved across different cell types.

    “Notwithstanding these distinctions, the global architecture of HIF-1- and HIF-2-dependent target gene networks remains largely conserved across different cell types [7,66,68,70]”

    From HIF inhibition: Current strategies and clinical challenges (2026) · cites this paper as [7]

    The Discussion (page unavailable) says the paper’s HIF-binding-motif analysis agrees well with results from cancer cell lines, despite the different cell types. It also reports overlapping HIF-1 and HIF-2 targets in endothelial cells. These findings support some cross-cell-type similarity, but do not establish that the global architecture of their target-gene networks is largely conserved across different cell types. (LLM, conf=0.82)

  • Genes governed by overlapping HIF-1- and HIF-2-dependent regulatory inputs exhibited the strongest induction during hypoxia, including classical targets such as VEGFA and GLUT1.

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.
