S1943 NMHC-IIA phosphorylation regulates MMP9 secretion. (A) Gelatin zymography of conditioned medium from MDA-MB-231 cells expressing wild-type, S1943A or S1943E NMHC-IIA. Standards are human proMMP9 and active MMP2. (B and C) Biotrak MMP9 activity assay of (B) total MMP9 and (C) active MMP9 in conditioned medium from MDA-MB-231 cells expressing wild-type, S1943A or S1943E NMHC-IIA. Data represent the mean ± SEM from 3 independent experiments. Statistical analyses were performed using ANOVA.
