Western blot analysis of eIF4E protein levels in normal breast epithelial and stromal cells and breast cancer cell lines. An analysis was performed for each cell line used (fibroblasts, HMEC, MDA-MB-231, MDA-MB-361, and MDA-MB-435) for expression of CXCR4, eIF4E and b-actin. (A) A representative of three independent Western blot experiments. (B) Densitometric ratios of CXCR4 and eIF4E levels normalized to b-actin.
