1638993-5	1992	Exposure of early neural plate stage embryos to retinoic acid caused reduced expression of TGF beta 1 and TGF beta 2 proteins but had no effect on TGF beta 3.	Tretinoin	48-61	transforming growth factor, beta 1	Mus musculus	91-101	
1638993-5	1992	Exposure of early neural plate stage embryos to retinoic acid caused reduced expression of TGF beta 1 and TGF beta 2 proteins but had no effect on TGF beta 3.	Tretinoin	48-61	transforming growth factor, beta 2	Mus musculus	106-116	
1638993-8	1992	The down-regulation of intracellular TGF beta 1 was observed up to 48 hours after initial exposure to retinoic acid while some down-regulation of TGF beta 2 was still seen up to 60 hours after initial exposure.	Tretinoin	102-115	transforming growth factor, beta 1	Mus musculus	37-47
