Protein expression of p21 and p27 and phosphorylation and protein expression of cdc2 in Jurkat T cells after 1-15 min simulated weightlessness (μg) without (con, a) and with stimulation with PMA at the onset of simulated weightlessness (PMA, b). 1g-control experiments have been performed inside the clinostat, but without rotation. 5 independent experiments were performed and pooled proteins were analyzed. One representative beta-actin control is shown.
