STAT3 and breast cancer: A group of these molecular signaling pathways involved in proliferation and migration of BC cells, and enhance their viability known as oncogenic pathways such as Wnt [15], STAT3 [16], Nrf2 [17], PI3K/Akt [18], ZEB [19], and oncogenic microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) [20,21].
