According to statistical data published in 2019, breast cancer is among the leading causes of death in women worldwide. The serine/threonine kinase (AKT) or protein kinase B (PkB) signaling pathway is activated by phosphorylation processes, which further is associated with cell growth, proliferation, and survival, but also with activation of glucose metabolism. Mutations of the AKT signaling pathway components (especially PI3KCA and PTEN) have been observed in breast cancer patients, which are associated with resistance to hormonal treatment. Many clinical trials are testing the effect of AKT inhibition in order to block the growth and proliferation of breast cancer cells. The purpose of this review is to present the incidence of this neoplastic disease, to describe AKT signaling pathways activation, mutations that occur at its level, and inhibitors that can block this protein kinase.
