RANKL stimulates MK2 phosphorylation in dOCP^<i>lo</i> pre-osteoclasts.

<p>(A) Representative western blot of pre-osteoclasts from male mice primed with M-CSF (10 ng/mL) for two days and stimulated with RANKL (100 ng/mL) for the indicated minutes (min). Densiometric analysis of (B) p38 (left) and (C) p-p38 (right) as a percent of GAPDH. Data are expressed as means ± SE compared to <i>Mk2</i>^<i>+/+</i> controls (*<i>P</i>≤0.05).
