Effect of retinoid analogues on mammary cancer in transgenic mice with c-neu breast cancer oncogene.
    Breast cancer research and treatment, 1998, Volume: 48, Issue:3

    Breast cancer is one of the most common cancers and is a leading cause of mortality in women. The TG.NK transgenic mouse line expresses the c-neu breast cancer oncogene under the control of an MMTV promoter and appears to be a useful animal model for evaluation of intervention strategies to delay/prevent breast cancer. Fiber-rich nonpurified diet (NTP-2000), as compared to a purified diet (AIN-76A), has previously been shown to significantly delay the development of mammary cancer in the TG.NK model. Four-week old hemizygous TG.NK female mice with MMTV/c-neu oncogene were fed NTP-2000 diet containing the retinoid analogue 4-hydroxyphenyl retinamide (4-HPR) at 5 mM/kg or an arotinoid Ro 40-8757 at 2 and 3 mmol/kg for 26 weeks. The 4-HPR at 5 mmol/kg diet delayed the development of palpable tumors up to 24 weeks, but by 26 weeks, the incidence was not significantly different from the NTP-2000 diet control group. However, the 4-HPR diet markedly decreased the average weight of the tumors at 26 weeks. The 4-HPR diet also caused a significant increase in body weight without an increase in food consumption. Arotinoid Ro-40-8757 at both doses inhibited the development of mammary tumors for the duration of the study. However, the Ro 40-8757 at 3 mmol/kg appeared to be toxic as indicated by a significant depression of the average body weight with alopecia and skin scaling in some mice. Our observations with TG.NK transgenic mouse and fiber-rich diet (NTP-2000) indicate that the arotinoid Ro 40-8757 has a markedly higher inhibitory effect on the development of mammary cancer than 4-HPR. Studies to evaluate genetic changes and expression of hormonal receptors and growth factors associated with the inhibition of mammary cancer development by the retinoid analogues are in progress.
