Development of a novel method for measuring in vivo breast epithelial cell proliferation in humans

Abstract

Cell proliferation plays an important role in all stages of carcinogenesis. Currently, no safe, direct, in vivo method of measuring breast epithelial cell (BEC) proliferation rates in humans exists. Static immunohistochemical markers of cell proliferation, such as Ki-67 and PCNA indices, have technical limitations including high inter-lab variability, inaccuracy in the presence of agents that cause G1/S cell cycle block and inadequate sensitivity in post-menopausal women with low BEC proliferation rates. We describe here a safe, direct method of measuring BEC proliferation rates in vivo in women using heavy water ((2)H(2)O) labeling coupled with mass spectrometric analysis. Proliferation of normal and tumor BEC was measured from breast tissue biopsies in women undergoing mastectomy (n = 11) and normal BEC from healthy volunteers (n = 16). Women took heavy water (50-150 ml per day) for 1-4 weeks. Pre-menopausal women had significantly higher proliferation rates than post-menopausal women (0.7 +/- 0.1 versus 0.2 +/- 0.1 new cells per day, respectively), and tumor BEC had different proliferation rates than normal BEC from the same breast. The method is analytically reproducible and remains sensitive in the range of low proliferation rates. In summary, this novel method of measuring BEC proliferation in vivo holds promise for assessing the effects of anti-proliferative chemopreventive and chemotherapeutic agents.

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.
