产品描述:
Nuclear retinoic acid receptors (RARs) are transcriptional regulators with roles in cell proliferation and differentiation. BMS 453 is a synthetic retinoid that acts as an agonist of RARβ and an antagonist of RARα and RARγ.{30780} It has been shown to inhibit the proliferation of normal breast cells via the induction of TGF-β activity, causing G1 arrest.{30782} BMS 453 binding to RARα and RARγ can induce a transrepression of phorbol ester-induced AP-1 activity (IC50s = ~0.1 nM in HeLa and MCSF-7 cells), which also correlates with reduced cell proliferation.{30780} BM 453 has been used to trigger the differentiation of mouse embryonic stem cells (mES) in a study of RARβ-induced mES cell adipogenesis.{30781}
