Description:
Despite the tremendous progress in breast cancer diagnosis and treatment, the mortality rate
is expected to increase due to the emergence of drug resistance. Pro-inflammatory markers
are thought to contribute to drug resistance by activation of its naive receptors and its
downstream signaling pathways. Elevation of pro-inflammatory markers leads to an increase
in the biosynthesis of estrogen which can promote the proliferation of estrogen receptor (ER)+
breast cancer. Inflammation also results in obesity which is one of the key risk factors. Estrogen
receptor-beta (ER-?) is an important target that has been widely studied and accepted to possess
anti-cancer activity in a number of cancers including breast cancer. ER-? elicits its action through
genomic and non-genomic pathways. The genomic pathway increases the transcription of
potent cyclin-dependent kinase inhibitor (p21), and tumor suppressor genes such as melanoma
differentiation associated gene 7 and tumor protein (p53). The non-genomic pathway works
through protein-protein interaction and phosphorylation. Here, we propose that the activation
of ER-? might enhance the activation of nuclear factor-erythroid factor 2-related factor 2 (Nrf2)
via estrogen receptor-alpha (ER-?) repression. The activation of Nrf2 increases the transcription
of antioxidant genes such as NADH quinone oxidoreductase 1 (NQO1), heme oxygenase-1 (HO1), etc., and decreases the expression of pro-inflammatory genes such as tumor necrosis factor-?
(TNF-?), interleukin-1 (IL-1), etc. This review hypothesizes and suggests that ER-? agonists
could play a beneficial role to overcome inflammation-related drug resistance by modulation of
the Nrf2/antioxidant response element (Nrf2/ARE) pathway
