Figure 4Cytoplasmic translocation of Smad7 is increased in
Itga3–/– keratinocytes.
WT or
Itga3–/– keratinocytes were treated with TGF-β1 for 0, 0.5, 1, 2, 3, or 7 hours, and cytoplasmic or nuclear extracts were analyzed by Western blotting for Smad7 (
A), phospho-Smad2 (
B), phospho-Smad3 (
C), and Smad4 (
D). Graphs represent mean (±SEM) densitometry results relative to mean HSC-70 (for cytoplasmic extracts,
A) or PCNA (for nuclear extracts,
B–
D) loading control levels.
n = 3–4 independent experiments. Solid line, WT; dashed line,
