Background:

BMS 453 is a synthetic RAR (retinoic acid receptor) antagonist [1].
The retinoic acid receptors (RARα, RARβ, RARγ) belong to steroid nuclear receptor superfamily and the expressions of retinoid receptor RARα and RARβ are correlated with the antiproliferative effects of retinoids.
In normal breast cells, BMS453 inhibited the cell proliferation without significantly apoptosis. BMS 453 blocked the G1/S transition of the cell cycle with an increase in the amount of cells in G0/G1 and a decrease in the amount of cells in S phase. Also, BMS453 increased active TGFβ activity by 33-fold, which show BMS453 induces conversion of latent TGFβ to active TGFβ. TGFβ mediates the anti-proliferative effect of BMS453 in breast cells [1]. BMS 453 transrepresses AP-1 but does not activate RAR-dependent gene expression. In normal breast cells (HMEC and 184) and T47D breast cancer cells, BMS453 inhibited the growth of T47D breast cancer cells and normal breast cells (HMEC and 184). Breast cancer cells were resistant to BMS453 and normal human breast cells were most sensitive to BMS453. BMS453 may suppress growth by inhibiting transcription factors such as AP-1 [2].
