Table 1 Effects of genistein, EGF, 17β-estradiol and combinations of genistein with EGF or 17β-estradiol on accumulation of lysosomes containing complex storage structures in MPS IIIA fibroblasts

From: Genistein-mediated inhibition of glycosaminoglycan synthesis, which corrects storage in cells of patients suffering from mucopolysaccharidoses, acts by influencing an epidermal growth factor-dependent pathway
