SLC39A6 and breast cancer: This result is consistent with that observed by Taylor et al. [20] in breast cancer cell lines; Taylor KM et al. [20] found three SLC39A6 protein bands, particularly those at 103, 68, and 35 kDa; these bands are obtained because of the N-terminal proteolytic cleavage of SLC39A6 by using three anti-SLC39A6 antibodies.
