MUC1 and cancer: As shown in Figure 2, constitutive levels of mt-associated MUC1 C-ter are significantly linked to the intrinsic Δψm of subclones established from SW480 colonic, and MCF7 mammary, carcinoma cells (2A and 2B;; P = 0.0118 and 0.021, respectively), thereby supporting the relationship between the Δψm and mt associated MUC1 C-ter in cancer cells.
