Abstract

The growth of human breast tumor cells is regulated through signaling involving cell surface growth factor receptors and nuclear receptors of the steroid/thyroid/retinoid receptor gene family. Retinoic acid receptors (RARs), members of the steroid/thyroid hormone receptor gene family, are ligand-dependent transcription factors, which have in vitro and in vivo growth inhibitory activity against breast cancer cells. RAR-agonists inhibit the proliferation of many human breast cancer cell lines, particularly those whose growth is stimulated by estradiol (E2) or growth factors. Additionally, RAR-agonists and synthetic retinoids such as Ferentinide have been shown to induce apoptosis in malignant breast cells but not normal breast cells. To better define the genes involved in RAR-mediated growth inhibition of breast cancer cells, we used oligonucleotide microarray analysis to create a database of genes that are potentially regulated by RAR-agonists in breast cancer cells. We found that PDCD4 (programmed cell death 4), a tumor suppressor gene presently being evaluated as a target for chemoprevention, was induced about three-fold by the RARalpha-selective agonist Am580, in T-47D breast cancer cells. RAR pan-agonists and Am580, but not retinoid X receptors (RXR)-agonists, stimulate the expression of PDCD4 in a wide variety of retinoid-inhibited breast cancer cell lines. RAR-agonists did not induce PDCD4 expression in breast cancer cell lines, which were not growth inhibited by retinoi…

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.
