Mengyao et al. reported the correlation of IL-11 expression with Her-2 and Ki-67 expression in breast cancer, the correlation of IL-11Ra expression levels with ER, PR, and Her-2 expression while the co-expression of IL-11 and IL-11Ra was correlated with microvessel density and angiogenesis in breast cancer patients [37]. Here, MKI67 is linked to breast cancer.
