Figure 6. Rho GTPases facilitate TGF-β2 expression and secretion.
Confluent transformed human TM cells were incubated x 24h in the absence (PBS) or presence of C3 exoenzyme (10 μg/ml). Data shown are the means ± SEM (n=6) of (A) GAPDH-normalized TGF-β2 mRNA content or (B) biologically-active TGF-β2 protein present in media collected from cells treated as indicated. *, p < 0.05, Student’s t-test.
