Wang et al. demonstrated that IL-8 was activated by the PI3K-Akt signalling pathway and was involved in EMT in human breast cancer cells, ultimately promoting tumour growth and metastasis in vivo and in vitro and affecting the expression of the EMT-related biomarkers E-cadherin, Vimentin and Fibronectin [19]. Here, CXCL8 is linked to neoplasm.
