Comparison of steroid receptors from the androgen responsive ddt₁ cell line and the nonresponsive hvp cell line

Two hamster cell lines have been isolated from androgen target tissue. The DDT, cells derived from ductus deferens tissue exhibit a growth response to androgens, while the HVP cells derived from ventral prostate are androgen unresponsive. Both cell lines contain androgen receptors that are similar when compared by kinetic methods, sedimentation velocity, chromatographic procedures or nuclear translocation ability. The forms of the high salt extracted nuclear receptors are indistinguishable chromatographically. Therefore, we postulate that the lesion preventing androgen induced growth in the HVP cell line is subsequent to nuclear translocation of the steroid receptor complex.
