1 We previously showed that atRA (all-trans Retinoic Acid, atRA) inhibites chondrogenesis by downregulation of TGF-beta/Smad signaling. Tretinoin transforming growth factor, beta 1 Mus musculus
2 We previously showed that atRA (all-trans Retinoic Acid, atRA) inhibites chondrogenesis by downregulation of TGF-beta/Smad signaling. Tretinoin transforming growth factor, beta 1 Mus musculus
3 We previously showed that atRA (all-trans Retinoic Acid, atRA) inhibites chondrogenesis by downregulation of TGF-beta/Smad signaling. Tretinoin transforming growth factor, beta 1 Mus musculus
4 Further examinations revealed that TGIF exerted a pivotal role in regulating crosstalk of RA and TGF-beta signaling, since siRNA knockdown of TGIF partially abolished the ability of atRA to suppress TGF-beta3-induced chondrogenesis, whereas forced expression of TGIF blocked the ability of TGF-beta3 to relieve atRA-mediated the suppression of chondrogenesis. Tretinoin transforming growth factor, beta 1 Mus musculus
5 Further examinations revealed that TGIF exerted a pivotal role in regulating crosstalk of RA and TGF-beta signaling, since siRNA knockdown of TGIF partially abolished the ability of atRA to suppress TGF-beta3-induced chondrogenesis, whereas forced expression of TGIF blocked the ability of TGF-beta3 to relieve atRA-mediated the suppression of chondrogenesis. Tretinoin transforming growth factor, beta 1 Mus musculus
6 Furthermore, we demonstrated that the effects of atRA on TGF-beta-dependent gene activation and of TGF-beta on RA-dependent gene activation are mediated by TGIF with siRNA to downregulate TGIF. Tretinoin transforming growth factor, beta 1 Mus musculus
