Overall, our results point to the prognostic and therapeutic value of identifying AGTR1 overexpression in a subset of HER2-negative breast cancers, and they provide a mechanistic rationale to explore the repurposing of drugs that target angiotensin II-dependent NFκB signaling pathways to improve the treatment of this breast cancer subset.<b>Significance:</b> These findings offer a mechanistic rationale to explore the repurposing of drugs that target angiotensin action to improve the treatment of AGTR1-expressing breast cancers.<i></i>.

Recent studies on the role of two opposite axes of angiotensinogen metabolism - ACE (angiotensin-converting enzyme)/ANGII/AT1R (angiotensin receptor type 1) and ACE-2/ANG 1-7/MAS (mitochondrial assembly) - indicate their importance in tumor growth and invasion, but studies describing the metabolic pathways in breast cancer and the role of newer angiotensins, such as ANG 1-12, remain lacking.

In conclusion, it is hypothesized that Angiotensin II may be involved in regulation of tumor angiogenesis especially in receptor negative breast cancer by regulation of angiogenesis associated genes via At(1)R. These findings are the first evidence for targeting tumor angiogenesis by inhibition of At(1)R in receptor negative human breast cancer cells and may lead to new therapeutical anticancer strategies based upon inhibition of At(1)R.

Thus, we hypothesized that angiotensin II (Ang Ⅱ) can promote proliferation of breast cancer via activated AT1R; the activation of AT1R may play an important role in promoting breast cancer growth, and AT1R blocker (ARB) may suppress the promotional effect on proliferation by antagonizing AT1R.
