Bmi-1 determines the proliferative capacity of normal and leukaemic stem cells.

Lessard, Julie, Sauvageau, Guy·2003·Nature

Abstract

An emerging concept in the field of cancer biology is that a rare population of 'tumour stem cells' exists among the heterogeneous group of cells that constitute a tumour. This concept, best described with human leukaemia, indicates that stem cell function (whether normal or neoplastic) might be defined by a common set of critical genes. Here we show that the Polycomb group gene Bmi-1 has a key role in regulating the proliferative activity of normal stem and progenitor cells. Most importantly, we provide evidence that the proliferative potential of leukaemic stem and progenitor cells lacking Bmi-1 is compromised because they eventually undergo proliferation arrest and show signs of differentiation and apoptosis, leading to transplant failure of the leukaemia. Complementation studies showed that Bmi-1 completely rescues these proliferative defects. These studies therefore indicate that Bmi-1 has an essential role in regulating the proliferative activity of both normal and leukaemic stem cells.

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.
