Tumor necrosis factor (TNF)-α induces cytoskeleton and intercellular junction remodeling in
tubular epithelial cells; the underlying mechanisms, however, are incompletely explored. We
have previously shown that ERK-mediated stimulation of the RhoA GDP/GTP exchange
factor GEF-H1/Lfc is critical for TNF-α-induced RhoA stimulation. Here we investigated the
upstream mechanisms of ERK/GEF-H1 activation. Surprisingly, TNF-α-induced ERK and
RhoA stimulation in tubular cells were prevented by epidermal growth factor receptor …
