We hypothesized that a coactivator of the serum response factor (SRF), megakaryoblastic leukemia factor-1 (MKL1), stimulates alpha-smooth muscle actin (alpha-SMA) transcription in primary cultures of renal tubular epithelial cells (RTC), which convert into myofibroblasts on treatment with TGF-beta1.

We also show that Barx2, MyoD, and serum response factor simultaneously occupy the SMA promoter in cells and that Barx2 interacts with MyoD.

The expression of the transcriptional co-activator of SMA, serum response factor, was reduced by 50% after siRNA knockdown of mDia or by 100% in cells transfected with catalytically inactive mDia.

RhoAV14, lysophosphatidic acid, and TGF-beta (2) stimulated significant increases in Erk1/2 phosphorylation, paralleled by profound increases in fibronectin, serum response factor (SRF), and alpha-SMA expression.

The Rho-Rho kinase-myosin light chain-myocardin-related transcription factor (MRTF)-serum response factor (SRF) pathway and Rac1, p21-activated kinase (PAK) and p38 were described as important regulators of MRTF localization and SMA expression.

By using specific inhibitors and small interfering RNA (siRNA), we demonstrated that p38 MAPK pathway and serum response factor (SRF)-DNA binding activity is critical for the polymerized collagen-induced PDMC differentiation into SMCs.
