Catechins such as catechin, GC, and catechin gallate (CG) induced breast cancer cell apoptosis by suppressing the expression of anti-apoptotic factors such as B cell lymphoma 2 (Bcl-2), Bcl-xL, and survivin, accompanied by the inhibition of NFκB, JAK/STAT, and PI3K pathways [65]. Here, NFKB1 is linked to breast cancer.
