Abstract

Recent research has identified critical roles for microRNAs in a large number of cellular processes, including tumorigenic transformation. While significant progress has been made towards understanding the mechanisms of gene regulation by microRNAs, much less is known about factors affecting the expression of these noncoding transcripts. Here, we demonstrate for the first time a functional link between hypoxia, a well-documented tumor microenvironment factor, and microRNA expression. Microarray-based expression profiles revealed that a specific spectrum of microRNAs (including miR-23, -24, -26, -27, -103, -107, -181, -210, and -213) is induced in response to low oxygen, at least some via a hypoxia-inducible-factor-dependent mechanism. Select members of this group (miR-26, -107, and -210) decrease proapoptotic signaling in a hypoxic environment, suggesting an impact of these transcripts on tumor formation. Interestingly, the vast majority of hypoxia-induced microRNAs are also overexpressed in a variety of human tumors.

  • miR-23a was induced under hypoxic circumstances and can act upon pro-apoptotic signals to promote tumor formation and oncogenic transformation.

    “miR-23a was induced under hypoxic circumstances and can ultimately act upon pro-apoptotic signals to promote tumor formation and oncogenic transformation [89].”

    From Recent advances of miR-23 in human diseases and growth development (2025) · cites this paper as [89]

    The Results table reports increased miR-23a expression under hypoxia. The Discussion predicts that miR-23 targets pro-apoptotic components, but the paper does not demonstrate this effect for miR-23a or show that it promotes tumor formation or oncogenic transformation. The Results report caspase inhibition for miR-26, miR-107, and miR-210 instead. (LLM, conf=0.90)

  • Hypoxia, a general feature of all solid tumors, can induce miR-21 expression.

    “Another factor that can induce miR-21 expression is hypoxia, a general feature of all solid tumors (30).”

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.
