Aldehyde dehydrogenase: Its role as a cancer stem cell marker comes down to the specific isoform
Open accessAbstract
Recent evidence suggests that enhanced aldehyde dehydrogenase (ALDH) activity is a hallmark of cancer stem cells (CSC) measurable by the aldefluor assay. ALDH1A1, one of 19 ALDH isoforms expressed in humans, was generally believed to be responsible for the ALDH activity of CSCs. More recently, experiments with murine hematopoietic stem cells, murine progenitor pancreatic cells, and human breast CSCs indicate that other ALDH isoforms, particularly ALDH1A3, significantly contribute to aldefluor positivity, which may be tissue and cancer specific. Therefore, potential prognostic application involving the use of CSC prevalence in tumor tissue to predict patient outcome requires the identification and quantification of specific ALDH isoforms. Herein we review the suggested roles of ALDH in CSC biology and the immunohistological studies testing the potential application of ALDH isoforms as novel cancer prognostic indicators.

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.
