In our previous study, we found that T. pratense extract inhibited the proliferation of MCF‐7 and MDA‐MB‐231 BC cell lines and induced apoptosis and autophagy via activating genes such as p53, Bax, Caspase‐3, LC‐3, BECN‐1, and ATG‐7 in these cell lines (Khazaei & Pazhouhi, 2019). Here, BECN1 is linked to breast cancer.
