We analyzed if maternal obesity-inducing high fat diet (HFD) not only raises offsprings mammary malignancy risk but also impairs response to antiestrogen tamoxifen. Female rat offspring of HFD and control diet-fed dams, in which estrogen receptor-positive (ER+) mammary tumors were induced with the carcinogen 7,12-dimethylbenz[a]anthracene (DMBA), exhibited related initial reactions to antiestrogen tamoxifen. However, after tamoxifen therapy was completed, almost all (91%) tumors recurred in HFD offspring, compared with only 29% in control offspring. The increase in local mammary tumor recurrence in HFD offspring was linked to an increase in the markers of immunosuppression (2015). The incidence of maternal obesity was particularly high (56.7%) among African American (AA) women, compared with non-Hispanic White (NHW) ladies (33.2%) (Flegal 2016). Maternal obesity can have long-lasting adverse effects within the offspring that include an increased risk of type 2 diabetes, Danicopan asthma, cardiovascular diseases, autism and Alzheimers disease (OReilly & Reynolds 2013, Martin 2014, Nizari 2016). Maternal obesity also may increase a daughters breast malignancy risk because high birth weight is strongly linked to both maternal obesity (Yu 2013) and an increased breast malignancy risk Alarelin Acetate among daughters (Michels Danicopan 1996, Silva 2008). Inside a preclinical model, we earlier showed that maternal intake of an obesity-inducing high-fat.
