Abstract
A human mammary carcinoma originating from a postmenopausal patient was successfully transplanted into nude mice. According to the adopted criteria the tumour proved to be oestradiol- and progesterone-receptor-positive. Histological studies of the patient tumour revealed a ductal invasive mammary carcinoma with 80% tubular growth pattern. Following transplantation the adenoid structures decreased to 30%; the mitosis rate and grade of malignancy increased. Treatment of the nude mice with 20 micrograms oestradiol benzoate/mouse caused a loss of the oestradiol receptor of the mammary carcinoma. The mammary carcinoma 3366 can be used for testing of antineoplastic substances, antihormones and for studies in regard to down-regulation or blocking of hormone receptors and possible consequences for therapies.Entities:
