Abstract

Obesity is a risk factor for hormone receptor-positive breast cancer in postmenopausal women. Estrogen synthesis is catalyzed by aromatase, which is encoded by CYP19. We previously showed that aromatase expression and activity are increased in the breast tissue of overweight and obese women in the presence of characteristic inflammatory foci [crown-like structures of the breast (CLS-B)]. In preclinical studies, proinflammatory prostaglandin E2 (PGE2) is a determinant of aromatase expression. We provide evidence that cyclooxygenase (COX)-2–derived PGE2 stimulates the cyclic AMP (cAMP)→PKA signal transduction pathway that activates CYP19 transcription, resulting in increased aromatase expression and elevated progesterone receptor levels in breast tissues from overweight and obese women. We further demonstrate that a measure of in-breast inflammation (CLS-B index) is a better correlate of these biologic end points than body mass index. The obesity→inflammation→aromatase axis is likely to contribute to the increased risk of hormone receptor-positive breast cancer and the worse prognosis of obese patients with breast cancer. Significance: We show that obesity-associated inflammatory foci in the human breast are associated with elevated COX-2 levels and activation of the PGE2→cAMP→PKA signal transduction pathway resulting in increased aromatase expression. These findings help to explain the link among obesity, low-grade chronic inflammation, and breast cancer with important clinical implications. Cancer Discov; 2(4); 356–65. ©2012 AACR.

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.
