RAW264.7 cells were pretreated with SKI-5C (10 μM for 24 h) and then stimulated with LPS (1 μg/ml for 16 h). A Immunoblot analysis of Phospho-HDAC4. Data represent three independent experiments. B Colorimetric assay of CaMKII activity. C Immunoblot analysis of CaMKII-δ expression. Data represent three independent experiments. D Immunoblot analysis of phospho-CaMKII-δ. Data represent three independent experiments. E Co-immunoprecipitation analysis of the interaction between SphK1 and CaMKII-δ in LPS-stimulated RAW264.7 cells. F Pull-down analysis of HA, HA-SphK1, and His-CaMKII-δ proteins. Data are expressed as the mean ± standard deviation. *P < 0.05, **P < 0.01, ***P < 0.001. CaMKII-δ, calcium/calmodulin protein kinase II-δ.
