IL-8, but not MCP-1, alleviated serum starvation-induced growth arrest in MDA-MB231 cells in vitro. Serum-free medium (SFM) and SFM+20 nM epidermal growth factor (EGF) serve as the negative and positive controls, respectively. Average RFP% growth fold-change with SD of MCF7 (A) and MDA-MB231 cells (B) in SFM with chemokine treatment at the indicated concentration (n=4). Average RFP% fold-change and average EdU incorporation percentage with SD of MCF7 cells (C) and MDA-MB231 (D) cultured with LX-1-transwell insert±1 μg ml−1 CXCR2 antibody (n=3). *P<0.05, **P<0.01, ***P<0.001.
