Tidal stretch differently regulates the tensile and compressive cytoskeletal elements.

<p>Effects of static and dynamic Ptm on β-actin (act, ∼42 KDa) (<b>A</b> and <b>B</b>) and α-tubulin (tub, ∼50 KDa) (<b>C</b> and <b>D</b>) in intact bovine airways after 90 min of mechanical loading with (<b>B</b> and <b>D</b>) or without (<b>A</b> and <b>C</b>) constriction assessed by Western blots. T0: time 0 before stretch, St: static Ptm. D: dynamic Ptm oscillation. GAPDH (∼35 KDa) is loading control. Data are normalized such that the mean of the dynamic group is unity.
