Abstract

Transforming growth factor-beta (TGF-beta) plays central roles in embryonic development, organogenesis, and physiologic connective tissue remodeling during wound healing and tissue repair as well as in carcinogenesis. Estrogens have key roles in a variety of biological events, such as the development and maintenance of female reproductive organs and bone and lipid metabolism. Previous studies demonstrated that estrogens suppress TGF-beta-induced gene expression, such as type IV collagen in kidney mesangial cells. However, the molecular mechanisms that mediate this antagonistic effect are unknown. To elucidate the mechanisms of cross-talk between TGF-beta and estrogen receptor (ER) signaling pathways, we reconstituted TGF-beta and ER signaling in human kidney carcinoma cells. Here we demonstrate that TGF-beta-induced activation of Sma and MAD-related protein 3 (Smad3) activity, one of the major intracellular transducers of TGF-beta signaling, was suppressed by ER, whereas ER-mediated transcriptional activation was enhanced by TGF-beta signaling. We provide evidence that this two-way cross-talk between the estrogen and TGF-beta signaling pathways was the result of direct physical interactions between Smad3 and ER. These findings have implications for a variety of disease states, such as the pathophysiology of kidney function, atherosclerosis, and breast cancer.

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.
