19255510-4	2009	We found that atRA suppressed chondrogenesis and Smad2/3 phosphorylation regardless of the presence of TGF-beta3.	Tretinoin	14-18	SMAD family member 2	Mus musculus	49-56	
19255510-5	2009	Functional assays indicated that TGF-beta3 treatment or co-transfection of expressing Smad2/3 vectors suppressed atRA-induced RARE-tk-Luc activity.	Tretinoin	113-117	SMAD family member 2	Mus musculus	86-93
