Randomized trial investigates TGF-β's role in aggrecan expression in chondrogenic cells, indicating critical signaling pathways.

The study aims to elucidate the role of Smad and MAPK pathways in TGF-β-induced aggrecan gene expression in chondrogenic ATDC5 cells.
Utilized chondrogenic ATDC5 cell line to study TGF-β signaling pathways
Administered various inhibitors to dissect the roles of ERK1/2 and p38 MAPK
Measured aggrecan expression following TGF-β treatment and pathway inhibition.
TGF-β rapidly induced aggrecan expression within 3 hours, requiring de novo protein synthesis (p<0.05)
Inhibition of Smad, ERK1/2, or p38 pathways significantly reduced aggrecan expression (p<0.01)
Basal ERK1/2 and p38 MAPK activation correlated with aggrecan levels, indicating their essential roles.

Watanabe et al. (2001) studied this question.
