A) The expression level of FABP7 as detected by Affymetrix microarray analysis in WM35 cells grown as spheroids for 24 hrs with or without PMA and/or PD98059 compared to untreated monolayer control. B) FABP7 mRNA expression levels in the same cells as in (A) measured by real time RT-PCR. The results presented are relative to untreated monolayer control. The average was calculated from three independent experiments and presented with standard deviation. C) Expression of the FABP7 protein by Western blot analysis. Down-regulation of FABP7 mRNA and protein was seen after treatment with PMA and PD98059 for 24 hrs. α-tubulin was used as loading control.
