Smurf2 is upregulated in human breast cancer cell lines. (A) Smurf2 was found to be specifically upregulated in MDA-MB-231 cell line compared to other breast cancer cell lines. An untransformed immortalized cell line, MCF-10A was used as the control. β-actin was used to verify equal gel loading. (B) The bar graph indicates relative levels for Smurf2 protein in cancer cell lines to that in MCF10A. The density of each Smurf2 signal was normalized by β-actin. Data shows mean value ± S.E. from three independent experiments.
