Fig. 9. Myosin inhibitors decrease Arp2 mRNA localization in the CEFs. CEFs were serum starved for 16 hours and then stimulated with 10% FBS alone (no drug) or 10% FBS plus 20 mM BDM, 100 µM H7, 40 µM ML-7 or 100 µM blebbistatin for 2 hours before fixation for FISH-TSA for Arp2 mRNA. Data are from at least 300 cells that derived from at least three independent experiments with error bar indicating s.e.m. All the data from drug-treated samples are significantly different from the no drug control (P<0.01).
