Abstract

Exposure to ionizing radiation (IR) and certain chemotherapeutic agents not only causes acute bone marrow (BM) suppression but also leads to long-term residual hematopoietic injury. This latter effect has been attributed to damage to hematopoietic stem cell (HSC) self-renewal. Using a mouse model, we investigated whether IR induces senescence in HSCs, as induction of HSC senescence can lead to the defect in HSC self-renewal. It was found that exposure of C57BL/6 mice to a sublethal dose (6.5 Gy) of total body irradiation (TBI) resulted in a sustained quantitative and qualitative reduction of LKS+ HSCs. In addition, LKS+ HSCs from irradiated mice exhibited an increased expression of the 2 commonly used biomarkers of cellular senescence, p16(Ink4a) and SA-beta-gal. In contrast, no such changes were observed in irradiated LKS- hematopoietic progenitor cells. These results provide the first direct evidence demonstrating that IR exposure can selectively induce HSC senescence. Of interest, the induction of HSC senescence was associated with a prolonged elevation of p21(Cip1/Waf1), p19(Arf), and p16(Ink4a) mRNA expression, while the expression of p27(Kip1) and p18(Ink4c) mRNA was not increased following TBI. This suggests that p21(Cip1/Waf1), p19(Arf), and p16(Ink4a) may play an important role in IR-induced senescence in HSCs.

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.
