Transforming growth factor-beta (TGF-beta) plays a pivotal role in the extracellular matrix accumulation observed in chronic progressive tissue fibrosis, but the intracellular signaling mechanism by which TGF-beta stimulates this process remains poorly understood. We examined whether mitogen-activated protein kinase (MAPK) routes were involved in TGF-beta1-induced collagen expression in L(6)E(9) myoblasts. TGF-beta1 induced p38 and extracellular signal-regulated kinase (ERK) 1/2 phosphorylation whereas no effect on Jun N-terminal kinase phosphorylation was observed. Biochemical blockade of p38 but not of the ERK MAPK pathway abolished TGF-beta1-induced alpha(2)(I) collagen mRNA expression and accumulation. These data indicate that TGF-beta1-induced p38 activation is involved in TGF-beta1-stimulated collagen synthesis.
