The patterns of mHsp70 and EpCAM expression by MDA-MB-231 (mHsp70: 50 ± 3%, EpCAM: 90 ± 2%), MCF7 (mHsp70: 51 ± 6%, EpCAM: 99 ± 4%), and T47D (mHsp70: 25 ± 7%, EpCAM: 98 ± 5%) breast cancer cells that were analyzed at TUM and NTU were nearly identical (data not shown). Here, EPCAM is linked to breast cancer.
