VIM and breast carcinoma: When quantified, vimentin expression was significantly decreased in all NHE1 mutant breast cancer cells (*P < 0.001, N = 3, Figure 6d); however, the down-regulation of vimentin observed in S703A cells (+P < 0.01, N = 3, Figure 6d) was greater than that of SSSA and 1K3R4E cells.
