Fig. 1. Estrone sulfatase activities in the homogenate in various breast cancer cell lines. The estrone sulfatase activities were measured in function of the substrate concentration and using the homogenates of the hormone-dependent cells MCF-7 and T-47D, or in hormone-independent MDA-MB-231 and M D A - M B - 4 3 6 cells. The data represent the mean of 2-4 determinations. Quoted from Ref. [18] with the permission 'Breast Cancer Research and Treatment'.
