Expression of PTEN and DNMT1 in 293T cells with miRNA-148a knockdown and incubated with MDEs. Expression of PTEN (a) and DNMT1 (c) proteins was analyzed in 293T miRNA-148a knockdown cells following incubation with MDEs. Protein expression was determined by Western blot. β-Catenin and β-actin were used as loading controls. Quantification was performed with NIH-Image software (http://rsb.info.nih.gov/nih-image/download.html) (b and d) **p < 0.01
